BACKGROUND OF THE INVENTION

0002Analyte monitoring devices have been used as medical diagnostic devices to determine a level of analyte from a sample. One common application is glucose measurements. For example, an analyte monitoring device is used with a remote sensor to perform an analyte reading. The sensor may be configured for implantation (e.g., subcutaneous, venous, or arterial implantation) into a patient. The analyte monitoring device processes signals from the remote sensor to determine the concentration or level of analyte in the subcutaneous tissue and may display the current level of the analyte.

DETAILED DESCRIPTION OF THE INVENTION

0004Before the present inventions are described, it is to be understood that this invention is not limited to particular aspects described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

0005Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limits of that range is also specifically disclosed. Each smaller range between any stated value or intervening value in a stated range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included or excluded in the range, and each range where either, neither or both limits are included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.

0006Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, some potential and preferred methods and materials are now described. All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. It is understood that the present disclosure supercedes any disclosure of an incorporated publication to the extent there is a contradiction.

0007It must be noted that as used herein and in the appended claims, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a program update" includes a plurality of such program updates and reference to "the program update" includes reference to one or more program updates and equivalents thereof known to those skilled in the art, and so forth.

0008Generally, embodiments of the present disclosure relate to in vivo methods and devices for detecting at least one analyte such as glucose in body fluid. Accordingly, embodiments include in vivo analyte sensors configured so that at least a portion of the sensor is positioned in the body of a user (e.g., within the ISF), to obtain information about at least one analyte of the body, e.g., transcutaneously positioned in user's body. In certain embodiments, an in vivo analyte sensor is coupled to an electronics unit that is maintained on the body of the user such as on a skin surface, where such coupling provides on body, in vivo analyte sensor electronics assemblies.

0009In certain embodiments, analyte information is communicated from a first device such as an on body electronics unit to a second analyte monitoring device which may include user interface features, including a display, and/or the like.

0010In many embodiments of the system, analyte information derived by the sensor/on body electronics (for example, on body electronics assembly) is made available in a user-usable or viewable form only when queried by the user such that the timing of data communication is selected by the user. The on-body electronics may take periodic measurement and record such data until an on-demand reading is taken by the user (e.g., the display device brought in close vicinity of the on-body electronics and sensor). Upon communication, the on-body electronics may communicate the recorded data for a set time period. For example, the on-body electronics may have 8 hours of memory in which it stores periodic measurements taken every 15 minutes. When an on-demand reading is taken, the entire 8 hours is transferred to the device. It should be appreciated that if the user does not take an on-demand reading for longer than 8 hours, some of the data may be lost.

0011Accordingly, in certain embodiments once a sensor electronics assembly is placed on the body so that at least a portion of the in vivo sensor is in contact with bodily fluid such as ISF and the sensor is electrically coupled to the electronics unit, sensor derived analyte information may be communicated from the on body electronics to a display device on-demand by powering on the display device, and executing a software algorithm stored in and accessed from a memory of the display device, to generate one or more request commands, control signal or data packet to send to the on body electronics. The software algorithm executed under, for example, the control of the microprocessor or application specific integrated circuit (ASIC) of the display device may include routines to detect the position of the on body electronics relative to the display device to initiate the transmission of the generated request command, control signal and/or data packet.

0012Display devices may also include programming stored in memory for execution by one or more microprocessors and/or ASICs to generate and transmit the one or more request command, control signal or data packet to send to the on body electronics in response to a user activation of an input mechanism on the display device such as depressing a button on the display device, triggering a soft button associated with the data communication function, and so on. The input mechanism may be alternatively or additionally provided on or in the on body electronics which may be configured for user activation. In certain embodiments, voice commands or audible signals may be used to prompt or instruct the microprocessor or ASIC to execute the software routine(s) stored in the memory to generate and transmit the one or more request command, control signal or data packet to the on body device. In the embodiments that are voice activated or responsive to voice commands or audible signals, on body electronics and/or display device includes a microphone, a speaker, and processing routines stored in the respective memories of the on body electronics and/or the display device to process the voice commands and/or audible signals. In certain embodiments, positioning the on body device and the display device within a predetermined distance (e.g., close proximity) relative to each other initiates one or more software routines stored in the memory of the display device to generate and transmit a request command, control signal or data packet.

0013Different types and/or forms and/or amounts of information may be sent for each on demand reading, including but not limited to one or more of current analyte level information (i.e., real time or the most recently obtained analyte level information temporally corresponding to the time the reading is initiated), rate of change of an analyte over a predetermined time period, rate of the rate of change of an analyte (acceleration in the rate of change), historical analyte information corresponding to analyte information obtained prior to a given reading and stored in memory of the assembly. Some or all of real time, historical, rate of change, rate of rate of change (such as acceleration or deceleration) information may be sent to a display device for a given reading. In certain embodiments, the type and/or form and/or amount of information sent to a display device may be preprogrammed and/or unchangeable (e.g., preset at manufacturing), or may not be preprogrammed and/or unchangeable so that it may be selectable and/or changeable in the field one or more times (e.g., by activating a switch of the system, etc). Accordingly, in certain embodiments, for each on demand reading, a display device will output a current (real time) sensor-derived analyte value (e.g., in numerical format), a current rate of analyte change (e.g., in the form of an analyte rate indicator such as a arrow pointing in a direction to indicate the current rate), and analyte trend history data based on sensor readings acquired by and stored in memory of on body electronics (e.g., in the form of a graphical trace). Additionally, the on skin or sensor temperature reading or measurement associated with each on demand reading may be communicated from the on body electronics to the display device. The temperature reading or measurement, however, may not be output or displayed on the display device, but rather, used in conjunction with a software routine executed by the display device to correct or compensate the analyte measurement output to the user on the display device.

0014As described, embodiments include in vivo analyte sensors and on body electronics that together provide body wearable sensor electronics assemblies (also referred to herein as a "patch"). In certain embodiments, in vivo analyte sensors are fully integrated with on body electronics (fixedly connected during manufacture), while in other embodiments they are separate but connectable post manufacture (e.g., before, during or after sensor insertion into a body). On body electronics may include an in vivo glucose sensor, electronics, battery, and antenna encased (except for the sensor portion that is for in vivo positioning) in a waterproof housing that includes or is attachable to an adhesive pad.

0015Embodiments include sensor insertion devices, which also may be referred to herein as sensor delivery units, or the like. Insertion devices may retain on body electronics assemblies completely in an interior compartment, i.e., an insertion device may be "pre-loaded" with on body electronics assemblies during the manufacturing process (e.g., on body electronics may be packaged in a sterile interior compartment of an insertion device). In such embodiments, insertion devices may form sensor assembly packages (including sterile packages) for pre-use or new on body electronics assemblies, and insertion devices configured to apply on body electronics assemblies to recipient bodies.

0016Embodiments include portable handheld display devices, as separate devices and spaced apart from an on body electronics assembly, that collects information from the assemblies and provide sensor derived analyte readings to users. Such devices may also be referred to as meters, readers, monitors, receivers, human interface devices, companions, or the like. Certain embodiments may include an integrated in vitro analyte meter. In certain embodiments, display devices include one or more wired or wireless communications ports such as USB, serial, parallel, or the like, configured to establish communication between a display device and another unit (e.g., on body electronics, power unit to recharge a battery, a PC, etc).

0017Compatible informatics software in certain embodiments include, for example, but not limited to stand alone or network connection enabled data management software program, resident or running on a display device, personal computer, a server terminal, for example, to perform data analysis, charting, data storage, data archiving and data communication as well as data synchronization. Informatics software in certain embodiments may also include software for executing field upgradable functions to upgrade firmware of a display device and/or on body electronics unit to upgrade the resident software on the display device and/or the on body electronics unit, e.g., with versions of firmware that include additional features and/or include software bugs or errors fixed, etc.

0018Embodiments may include a haptic feedback feature such as a vibration motor or the like, configured so that corresponding notifications (e.g., a successful on-demand reading received at a display device), may be delivered in the form of haptic feedback.

0019Embodiments include programming embedded on a computer readable medium, i.e., computer-based application software (may also be referred to herein as informatics software or programming or the like) that processes analyte information obtained from the system and/or user self-reported data. Application software may be installed on a host computer such as a mobile telephone, PC, an Internet-enabled human interface device such as an Internet-enabled phone, personal digital assistant, or the like, by a display device or an on body electronics unit. Informatics programming may transform data acquired and stored on a display device or on body unit for use by a user.

0020Embodiments of the subject disclosure are described primarily with respect to glucose monitoring devices and systems, and methods of glucose monitoring, for convenience only and such description is in no way intended to limit the scope of the disclosure. It is to be understood that the analyte monitoring system may be configured to monitor a variety of analytes at the same time or at different times.

0021For example, analytes that may be monitored include, but are not limited to, acetyl choline, amylase, bilirubin, cholesterol, chorionic gonadotropin, creatine kinase (e.g., CK-MB), creatine, DNA, fructosamine, glucose, glutamine, growth hormones, hormones, ketones, lactate, oxygen, peroxide, prostate-specific antigen, prothrombin, RNA, thyroid stimulating hormone, and troponin. The concentration of drugs, such as, for example, antibiotics (e.g., gentamicin, vancomycin, and the like), digitoxin, digoxin, drugs of abuse, theophylline, and warfarin, may also be monitored. In those embodiments that monitor more than one analyte, the analytes may be monitored at the same or different times, with a single sensor or with a plurality of sensors which may use the same on body electronics (e.g., simultaneously) or with different on body electronics.

0022As described in detail below, embodiments include devices, systems, kits and/or methods to monitor one or more physiological parameters such as, for example, but not limited to, analyte levels, temperature levels, heart rate, user activity level, over a predetermined monitoring time period. Also provided are methods of manufacturing. Predetermined monitoring time periods may be less than about 1 hour, or may include about 1 hour or more, e.g., about a few hours or more, e.g., about a few days of more, e.g., about 3 or more days, e.g., about 5 days or more, e.g., about 7 days or more, e.g., about 10 days or more, e.g., about 14 days or more, e.g., about several weeks, e.g., about 1 month or more. In certain embodiments, after the expiration of the predetermined monitoring time period, one or more features of the system may be automatically deactivated or disabled at the on body electronics assembly and/or display device.

0023For example, a predetermined monitoring time period may begin with positioning the sensor in vivo and in contact with a body fluid such as ISF, and/or with the initiation (or powering on to full operational mode) of the on body electronics. Initialization of on body electronics may be implemented with a command generated and transmitted by a display device in response to the activation of a switch and/or by placing the display device within a predetermined distance (e.g., close proximity) to the on body electronics, or by user manual activation of a switch on the on body electronics unit, e.g., depressing a button, or such activation may be caused by the insertion device, e.g., as described in <patcit id="pcit0004" dnum="US69812910A"><text>U.S. Patent Application No. 12/698,129 filed on February 1, 2010</text></patcit> and <patcit id="pcit0005" dnum="US61238646A"><text>U.S. Provisional Application Nos. 61/238,646</text></patcit>, <patcit id="pcit0006" dnum="US61246825B"><text>61/246,825</text></patcit>, <patcit id="pcit0007" dnum="US61247516B"><text>61/247,516</text></patcit>, <patcit id="pcit0008" dnum="US61249535B"><text>61/249,535</text></patcit>, <patcit id="pcit0009" dnum="US61317243B"><text>61/317,243</text></patcit>, <patcit id="pcit0010" dnum="US61345562B"><text>61/345,562</text></patcit>, and <patcit id="pcit0011" dnum="US61361374B"><text>61/361,374</text></patcit>, the disclosures of each of which are incorporated herein by reference for all purposes.

0024When initialized in response to a received command from a display device, the on body electronics retrieves and executes from its memory software routine to fully power on the components of the on body electronics, effectively placing the on body electronics in full operational mode in response to receiving the activation command from the display device. For example, prior to the receipt of the command from the display device, a portion of the components in the on body electronics may be powered by its internal power supply such as a battery while another portion of the components in the on body electronics may be in powered down or low power including no power, inactive mode, or all components may be in an inactive mode, powered down mode. Upon receipt of the command, the remaining portion (or all) of the components of the on body electronics is switched to active, fully operational mode.

0025Embodiments include transcutaneous sensors and also wholly implantable sensors and wholly implantable assemblies in which a single assembly including the analyte sensor and electronics are provided in a sealed housing (e.g., hermetically sealed biocompatible housing) for implantation in a user's body for monitoring one or more physiological parameters.

0035After the positioning of on body electronics 1110 on the skin surface and analyte sensor 1101 in vivo to establish fluid contact with ISF (or other appropriate body fluid), on body electronics 1110 in certain embodiments is configured to wirelessly communicate analyte related data (such as, for example, data corresponding to monitored analyte level and/or monitored temperature data, and/or stored historical analyte related data) when on body electronics 1110 receives a command or request signal from display device 120. In certain embodiments, on body electronics 1110 may be configured to at least periodically broadcast real time data associated with monitored analyte level which is received by display device 1120 when display device 1120 is within communication range of the data broadcast from on body electronics 1110, i.e., it does not need a command or request from a display device to send information.

0036For example, display device 1120 may be configured to transmit one or more commands to on body electronics 1110 to initiate data transfer, and in response, on body electronics 1110 may be configured to wirelessly transmit stored analyte related data collected during the monitoring time period to display device 1120. Display device 1120 may in turn be connected to a remote terminal 1170 such as a personal computer and functions as a data conduit to transfer the stored analyte level information from the on body electronics 1110 to remote terminal 1170. In certain embodiments, the received data from the on body electronics 1110 may be stored (permanently or temporarily) in one or more memory of the display device 1120. In certain other embodiments, display device 1120 is configured as a data conduit to pass the data received from on body electronics 1110 to remote terminal 1170 that is connected to display device 1120.

0037Referring still to <figref idref="f0001">FIG. 1</figref>, also shown in analyte monitoring system 1100 are data processing module 1160 and remote terminal 1170. Remote terminal 1 170 may include a personal computer, a server terminal a laptop computer or other suitable data processing devices including software for data management and analysis and communication with the components in the analyte monitoring system 1100. For example, remote terminal 1170 may be connected to a local area network (LAN), a wide area network (WAN), or other data network for unidirectional or bi-directional data communication between remote terminal 1170 and display device 1120 and/or data processing module 1160.

0038Remote terminal 1170 in certain embodiments may include one or more computer terminals located at a physician's office or a hospital. For example, remote terminal 1170 may be located at a location other than the location of display device 1120. Remote terminal 1170 and display device 1120 could be in different rooms or different buildings. Remote terminal 1170 and display device 1120 could be at least about one mile apart, e.g., at least about 110 miles apart, e.g., at least about 1100 miles apart. For example, remote terminal 1170 could be in the same city as display device 1120, remote terminal 1170 could be in a different city than display device 1120, remote terminal 1170 could be in the same state as display device 1120, remote terminal 1170 could be in a different state than display device 1120, remote terminal 1170 could be in the same country as display device 1120, or remote terminal 1170 could be in a different country than display device 1120, for example. In certain embodiments, a separate, optional data communication/processing device such as data processing module 1160 may be provided in analyte monitoring system 1100. Data processing module 160 may include components to communicate using one or more wireless communication protocols such as, for example, but not limited to, infrared (IR) protocol, Bluetooth protocol, Zigbee protocol, and 802.11 wireless LAN protocol. Additional description of communication protocols including those based on Bluetooth protocol and/or Zigbee protocol can be found in <patcit id="pcit0104" dnum="US20060193375A"><text>U.S. Patent Publication No. 2006/0193375</text></patcit> incorporated herein by reference for all purposes. Data processing module 1160 may further include communication ports, drivers or connectors to establish wired communication with one or more of display device 1120, on body electronics 1110, or remote terminal 1170 including, for example, but not limited to USB connector and/or USB port, Ethernet connector and/or port, FireWire connector and/or port, or RS-232 port and/or connector.

0039In certain embodiments, control logic or microprocessors of on body electronics 1110 include software programs to determine future or anticipated analyte levels based on information obtained from analyte sensor 1101, e.g., the current analyte level, the rate of change of the analyte level, the acceleration of the analyte level change, and/or analyte trend information determined based on stored monitored analyte data providing a historical trend or direction of analyte level fluctuation as function time during monitored time period. Predictive alarm parameters may be programmed or programmable in display device 1120, or the on body electronics 1110, or both, and output to the user in advance of anticipating the user's analyte level reaching the future level. This provides the user an opportunity to take timely corrective action.

0040Information, such as variation or fluctuation of the monitored analyte level as a function of time over the monitored time period providing analyte trend information, for example, may be determined by one or more control logic or microprocessors of display device 1120, data processing module 160, and/or remote terminal 1170, and/or on body electronics 1110. Such information may be displayed as, for example, a graph (such as a line graph) to indicate to the user the current and/or historical and/or and predicted future analyte levels as measured and predicted by the analyte monitoring system 1100. Such information may also be displayed as directional arrows (for example, see trend or directional arrow display 1131) or other icon(s), e.g., the position of which on the screen relative to a reference point indicated whether the analyte level is increasing or decreasing as well as the acceleration or deceleration of the increase or decrease in analyte level. This information may be utilized by the user to determine any necessary corrective actions to ensure the analyte level remains within an acceptable and/or clinically safe range. Other visual indicators, including colors, flashing, fading, etc., as well as audio indicators including a change in pitch, volume, or tone of an audio output and/or vibratory or other tactile indicators may also be incorporated into the display of trend data as means of notifying the user of the current level and/or direction and/or rate of change of the monitored analyte level. For example, based on a determined rate of glucose change, programmed clinically significant glucose threshold levels (e.g., hyperglycemic and/or hypoglycemic levels), and current analyte level derived by an in vivo analyte sensor, the system 1100 may include an algorithm stored on computer readable medium to determine the time it will take to reach a clinically significant level and will output notification in advance of reaching the clinically significant level, e.g., 30 minutes before a clinically significant level is anticipated, and/or 20 minutes, and/or 10 minutes, and/or 5 minutes, and/or 3 minutes, and/or 1 minute, and so on, with outputs increasing in intensity or the like.

0041Referring again back to <figref idref="f0001">FIG. 1</figref>, in certain embodiments, software algorithm(s) for execution by data processing module 1160 may be stored in an external memory device such as an SD card, microSD card, compact flash card, XD card, Memory Stick card, Memory Stick Duo card, or USB memory stick/device including executable programs stored in such devices for execution upon connection to the respective one or more of the on body electronics 1110, remote terminal 1170 or display device 1120.

PDAs as described above include, for example, portable electronic devices including one or more microprocessors and data communication capability with a user interface (e.g., display/output unit and/or input unit, and configured for performing data processing, data upload/download over the internet, for example. In such embodiments, remote terminal 170 may be configured to provide the executable application software to the one or more of the communication devices described above when communication between the remote terminal 1170 and the devices are established.

0043In still further embodiments, executable software applications may be provided over-the-air (OTA) as an OTA download such that wired connection to remote terminal 1170 is not necessary. For example, executable applications may be automatically downloaded as software download to the communication device, and depending upon the configuration of the communication device, installed on the device for use automatically, or based on user confirmation or acknowledgement on the communication device to execute the installation of the application. The OTA download and installation of software may include software applications and/or routines that are updates or upgrades to the existing functions or features of data processing module 1160 and/or display device 1120.

The installer program may be executed when the user couples the analyte monitoring device to the remote device. The installer program may then initiate the launch of the RD software on the remote device.

0051In some embodiments, the RD software is not stored in non-volatile memory on the remote device. The RD software is stored on the analyte monitoring device and used to launch the RD software on the remote device is coupled to the analyte monitoring device.

0052In some embodiments, the RD software may be downloaded and stored in non-volatile memory on the remote device. For example, the RD software may be downloaded via a network connection (e.g., via an internet connection), by storage device (e.g., CD-ROM, memory stick, etc.), and/or downloaded from the analyte monitoring device. In some instances, the RD software is capable of being run even when the device is not coupled to the computer.

0053It should be understood that the RD software may be compatible with various hardware systems (e.g., PC, MAC) and various operating systems (e.g., Windows, MAC OS, Linux).

0054The analyte monitoring device may be communicatively coupled to the remote device via wired technologies. Example wired technologies may include, but are not limited to, the following technologies, or family of technologies: USB, FireWire, SPI, SDIO, RS-232 port, etc.

0055The analyte monitoring device may include, for example, a communication connector unit to permit wired communication and coupling to the remote device. The communication connector unit provides the capability to communicate with a remote device having an appropriate interface to operatively couple with the communication connector. In some embodiments, the communication connector is configured to communicate with a smartphone such as an iPhone or Blackberry.

0056The communication connector unit may be any variety of connection interfaces-e.g., male or female connection interfaces. Using USB as an example, the communication connector may be any of the variety of USB plugs or USB receptacles/ports. As USB receptacles are typically located on computer and other devices, a corresponding USB plug used as a communication connector unit will enable the analyte monitoring device to be plugged directly into the USB receptacle, avoiding the use of cables. In other instances, the appropriate USB receptacle may be used on the analyte monitoring device to enable communication using a USB cable (similar to many other devices such as digital cameras, cellular phones, smartphones, etc.).

0057It should be appreciated that the in some embodiments the analyte monitoring device may be communicably coupled to the remote device via wireless technology.

0059The RD software may be launched on a remote device and used by the user (e.g., the patient) and/or a health care provider (HCP) (e.g., physician, hospital staff, etc.). For example, the HCP and/or patient may use the RD software on a remote device to analyze the patient data, view and print reports, view and change device settings, update device firmware and application software, etc.

0060In some instances, the RD software may initiate a comparison between the time date on the analyte monitoring device and that on the remote device and/or remote time server accessed via an internet connection from the remote device. The RD software may account for discrepancies and take action accordingly. For example, thresholds may be set (e.g., 5 minute difference) and if the threshold is reached, the analyte monitoring device prompts the user with a warning, question, indicator, etc., to acknowledge the discrepancy and/or remedy the discrepancy (e.g., adjust the time on one of the devices). In some instances, a similar comparison may be performed by the RD software to account for other discrepancies between the analyte monitoring device and remote device-e.g., discrepancies between data logs, data values, stored files, device and/or user interface configurations and settings, etc. The appropriate action can then be taken or requested.

0061Various defaults and customized configurations and settings may be established for generating, printing, saving, exporting, etc., reports. For example, the various formats for the report may be established (e.g., layout, style, themes, color, etc.); various file types to save the report as (e.g., PDF, Word document, Excel spreadsheet, etc. In some instances, for example, the RD software may provide the user with the ability to export tab-delimited text files or XML exports of the meter data (e.g., including blood glucose, ketones, carbs, insulin, and event tags, etc.).

The updates may be detected and downloaded automatically in some instances (e.g., when an internet connection is active) and/or detected and downloaded upon user confirmation or request. In some instances, updates to the software shall also update its installation files stored on the device. Moreover, in some instances, when the device firmware is updated, required labeling/user documentation is also updated on the device. In some instances, when device firmware is updated, the existing device settings and testing history (e.g., blood glucose, insulin, carb data, etc.) is preserved.

0064In some aspects of the present disclosure, Auto-Assist software may be loaded and launched on a remote data processing device to operate with a coupled analyte monitoring device. The Auto-Assist software may include one or more GUI's for communicating with the analyte monitoring device.

<i>Example Devices &amp; Systems</i>

0066<figref idref="f0002"><b>FIG. 2</b></figref> illustrates a block diagram of a system including an analyte monitoring device and remote data processing device, according to some embodiments. System 1500 is shown to comprising analyte monitoring device 1501 communicably coupled to remote device 1505. In some instances, as shown, remote device 1505 may have network access to a network 1510 in which a second remote device 1515 is shown coupled to. It should be understood that network 1510 may include one or more networks, including LANs, WANs, and/or the internet.

0067Analyte monitoring device 1501 is shown removably coupled to remote device 1505 via communication connector unit 1422. Communication connector unit, for example, includes a USB plug which couples with a USB receptacle 1507 in remote device 1505. Remote device 1505 may include peripheral devices, such as printer, keyboard, monitor, CD drive, etc. Remote device 1505 may also include, as shown, a network interface 1530 which connects it to network 510. Remote device 1515 is also connected to network 1510 and may communicate with remote device1 505 via network 1510.

0068The following paragraphs describe system 1500 during operation, according to some embodiments. In some instances, the analyte monitoring device described is a glucose monitoring device which measures the glucose concentration level of a blood sample. It should be understood that the description applies equally to other analytes and to other forms of samples.

0069In use, analyte monitoring device 1501 receives a test strip 1525 for measuring an analyte level of a sample applied to test strip 1525. Test strip 1525 is received at strip port unit 1520. Analyte monitoring device 1501 performs a measurement computation on the sample and the user can view the measurement reading on, for example, a touchsreen display (not shown). The user may also be presented with a menu on the touchscreen display to view and select-e.g., menus for storing data, downloading data, performing bolus calculations based on the measurement, etc.

0070The user may couple the analyte monitoring device 1501 to remote device 505 (e.g., a personal computer) via a communication connector unit. For example, the user may decide to store the measurement data and then choose to download stored test data (including stored measurement readings) to a remote device 1505.

0071Analyte monitoring device1 501 may then be coupled to remote device 1505 via communication connector unit 1422. Communication connector unit 1422 may, for example, include a USB plug which couples to a USB receptacle 1507 on remote device 1505.

0072In some instances, the analyte monitoring device 1501 may be powered by the remote device 1505 when coupled via the communication connector unit 1422. In such case, the user would couple the analyte monitoring device 1501 to the remote device 1505 and then insert test strip 1525 into the strip port 1520 to take a measurement reading. In some instances, the analyte monitoring device includes its own power source, such as button or AAA-size batteries, for example, and is not powered by the remote device 1505.

0073In some instances, the analyte monitoring device may be "locked" or prevented from performing a test while coupled to the remote device 1505. For example, medical device regulations such as high voltage isolation testing may be required if the analyte monitoring device is configured to perform tests while coupled to a remote device. Thus, "locking" or preventing the analyte monitoring device from performing a test while coupled to the remote device allows the analyte monitoring device to not be subjected to the additional testing, if so desired.

0074In some aspects, the analyte monitoring device 1501 may initiate a user interface application (e.g., RD software) to execute on the analyte monitoring device, and/or the remote device 1505 when coupled to the remote device 1505. The user interface application may be stored in a memory unit on the analyte monitoring device 1501, for example. In some aspects, the user is not required to have previously loaded software on the remote device 1505 to operate with the analyte monitoring device 1501. In some aspects, the analyte monitoring device may be configured to initiate the user interface application automatically upon coupling to the remote device. It should be understood that the user interface application may be configured to be compatible with various hardware systems (e.g., PC, MAC) and various operating systems (e.g., Windows, MAC OS, Linux).

0075The user interface application may include, for example, diabetes management related applications. The user interface application may provide a variety of menus, selections, charts, alarms, reminders, visual indicators, etc. For example, the user may be presented with menus and options, such as whether to take a measurement reading, to view stored measurement readings, to store data, to download data, to perform bolus calculation based on the measurement, etc.

0076The user interface program may, for example, allow the user to perform the following steps: (1) create a replica of the test data stored on the analyte monitoring device 1501, on the remote device 1505; and (2) synchronize test data from the analyte monitoring device 1501 to the database on the remote device 1505. Meter settings and/or user settings/preferences from the analyte monitoring device may also be included in the test data and synchronized with the remote device. Date and time for the remote device 1505 and analyte monitoring device 1501 may also be synched.

0077To read test data from the analyte monitoring device 1501 and write it to the remote device 1505, it is recognized herein that data in the remote device may be organized into tables, which may be organized into records, which may be broken down into predefined fields. Similarly, at some level data will be organized into records with a consistent field structure on the analyte monitoring device 1501. The user interface application may read test data from the analyte monitoring device and write it out to tables on the remote device 1505. The user interface application may also read data from table in the remote device 1505 and write them out to the analyte monitoring device 1501. Various types of data conversion may be used. For example, data residing in fields in the analyte monitoring device may be converted from the format it exists in the analyte monitoring device to a format compatible with the remote device, and vice versa. The logical structure of the records in the two systems may be different.

0078Remote device 1505 may include peripheral devices, such as printer, keyboard, monitor, CD drive, etc. Remote device 1505 includes a network interface which connects it to network 1510 (e.g., the internet). The user interface application may provide the user with the option to view test data on the monitor, to store test data on storage media (e.g., CD-ROM, memory card, etc.), further analyze and/or manipulate test data, transmit data to another device), and/or print out test data such as charts, reports, etc., on the printer.

0079As shown, remote device 1505 may also include a network interface 1530 (e.g., network interface card (NIC), modem, router, RF front end, etc.) used to connect the remote device 1505 to network 1510. For example, in some aspects, analyte monitoring device 1501 may couple via a USB connection to the remote device which may be a personal computer or laptop connected to the internet using a wireless modem and/or router. In some aspects, analyte monitoring device 1501 may couple via a micro USB connection to a remote device 1505 which is a smartphone having an RF front end to access a mobile network. The user interface application may provide a user interface for using the network connection of the remote device 1505-e.g., to forward test data to a physician, hospital, health provider, and/or other third party located at a second remote device 1515 on network 1510. Appropriate action may then be taken by the receiving party at the second remote device 1515.

0085<figref idref="f0002"><b>FIG. 3</b></figref> illustrates an analyte monitoring device used with a remote sensor, according to some embodiments. Sensor 1605 may be configured for implantation (e.g., subcutaneous, venous, or arterial implantation) into a patient. The sensor 1605 is coupled to sensor control unit 1610 which is typically attached to the skin of a patient. The sensor control unit 1610 operates the sensor 1605, including, for example, providing a voltage across the electrodes of the sensor 1605 and collecting signals from the sensor 1605. The sensor control unit 1610 may evaluate the signals from the sensor 605 and/or transmit the signals to wireless communication unit 1423 on analyte monitoring device 1501 for evaluation.

0086In some aspects, the wireless communication unit 1423 is configured to receive a signal from a remote sensor using radio-frequency identification (RFID) technology. This configuration may be used to provide glucose on demand capabilities, in which case when a measurement reading is desired, the analyte monitoring device is brought within close vicinity of the implantable sensor. In some instances, RFID technology may be used in continuous glucose monitoring (CGM) applications.

0087The analyte monitoring device 1501 processes the signals from the on-skin sensor control unit 1610 to determine the concentration or level of analyte in the subcutaneous tissue and may display the current level of the analyte via display unit 1421. Furthermore, the sensor control unit 1610 and/or the analyte monitoring device 1501 may indicate to the patient, via, for example, an audible, visual, or other sensory-stimulating alarm, when the level of the analyte is at or near a threshold level. For example, if glucose is monitored then an alarm may be used to alert the patient to a hypoglycemic or hyperglycemic glucose level and/or to impending hypoglycemia or hyperglycemia.

0088The analyte monitoring device 1501 may perform a variety of functions, including for example: modifying the signals from the sensor 605 using calibration data and/or measurements from a temperature probe (not shown); determining a level of an analyte in the interstitial fluid; determining a level of an analyte in the bloodstream based on the sensor measurements in the interstitial fluid; determining if the level, rate of change, and/or acceleration in the rate of change of the analyte exceeds or meets one or more threshold values; activating an alarm system if a threshold value is met or exceeded; evaluating trends in the level of an analyte based on a series of sensor signals; therapy management (e.g., determine a dose of a medication, etc.); and reduce noise or error contributions (e.g., through signal averaging or comparing readings from multiple electrodes); etc. The analyte monitoring device may be simple and perform only one or a small number of these functions or the analyte monitoring device may perform all or most of these functions.

0089Analyte monitoring device 1501 may communicate with a remote device 505 via communication connector unit 1422, and/or wireless communication unit 1423, and/or a second wireless communication unit (not shown), as described earlier.

<i>Hardware</i> - <i>Power On Interface</i>

0113<figref idref="f0003 f0004"><b>FIG. 4</b></figref> illustrates a method 100 of powering on an analyte monitoring device, such as a glucose monitoring device, according to one embodiment. The analyte monitoring device may also be referred to herein as a "reader" which takes measurement readings from the analyte sensor. From the off state, as represented by block 102, the device can be powered on by depressing a power button-e.g., by a "short" press or a "long press", as represented by block 104. At block 106, a test is performed to determine if the batter is depleted. If so, the device is powered off, as shown by block 108. In some instances, when the device recovers from a power loss, it can remember "sensor" status information and resume use of the same sensor if the sensor has not expired-e.g., a 14-day period, or other predetermined period. If the battery is determined to not be depleted, then the device is powered on, as shown at block 110.

0114At block 112, it is determined if this is the first time the device is to be set up. If it is the first time, then a First Start procedure is initiated to begin the setup of the device, as shown at block 114. If it is determined that this is not a first time setup, then it is determined if the sensor has already been activated. If not activated, then the home screen is displayed, as shown at block 118. If already activated, then it is determined whether the sensor is expired, as shown at block 120. If the sensor is expired, it is determined if the sensor expiration message has been previously displayed, as shown at block 130. If so, then the home screen is displayed, as shown at block 134. If not, then a sensor expiration screen is displayed, as shown at block 132. In some instances, an audible notification may also be provided. The sensor expiration screen may also inform the use that a new sensor must be started to take a glucose reading. Once confirmed by the user, for example by pressing "ok", the home screen is displayed on the device.

0115Referring back to block 120, if the sensor is not expired, then it is determined if the sensor is warming up, as shown by block 122. If not, then a prompt is displayed for a sensor scan. If the sensor is warming up, then a warm-up message screen is displayed that informs the user that the sensor is warming up, as shown at block 126. In some instances, such as shown, the warm-up message screen indicates the time remaining before the sensor can be used. An audible reminder may also be present, as shown. Once confirmed by the user, for example by pressing "ok", the home screen is displayed on the device.

At block 152, a current screen is displayed on the device. When a screen has been displayed for a predetermined period of time-e.g., 45 seconds or some other period of time, the screen brightness may dim to say power, as shown at block 154. If the user touches the dimmed screen the display returns to full brightness and the timeout timer resets. After the screen is dimmed, if another predetermined period of time has passed without any activity-e.g., 15 seconds or other time period-then the device will power off. It should be appreciated that there may be certain screens in which such method does not apply.

0118<figref idref="f0005"><b>FIG. 5C</b></figref> illustrates a method 160 of powering an analyte monitoring device off, according to one embodiment. From the home screen, shown at block 162, the pressing (e.g., short or long) of the home trigger button, as shown at block 164, will trigger the display of a screen indicating the device is to powering off. The user may be provided with an option to cancel the power down process. If no selection is detected, as shown at block 168, then the device may power down after a predetermined period of time-e.g., 5 seconds or some other time period, as represented by block 172. If at block 166 the trigger button is pressed, as shown at block 170, then the device is powered off, as represented by block 172.

0119<figref idref="f0005"><b>FIG. 5D</b></figref> illustrates a method 180 of powering off an analyte monitoring device, according to one embodiment. From a current screen, shown at block 182, the depression of the trigger button (e.g., a long depression) triggers the display of a power down screen shown at block 186. The user may be provided with an option to cancel the power down process. If no selection is detected, as shown at block 188, then the device may power down after a predetermined period of time-e.g., 5 seconds or some other time period, as represented by block 192. If at block 186 the trigger button is pressed, as shown at block 190, then the device is powered off, as represented by block 192.

<i>Low Battery Interface</i>

0120<figref idref="f0006"><b>FIG. 5E</b></figref> illustrates a battery low screen 196 for an analyte monitoring device that indicates that the battery of the device is low, according to one embodiment. In one embodiment, for example, this screen may appear after scanning of the sensor or a strip test, but before the results are shown. In some instance, this screen will start appearing when the battery capacity reaches a level equivalent to 1 day of typical use. This may be a predetermined value or based on a user history. In some instances, when the screen is display, a reminder auditory/vibratory signal is the only signal broadcast. The standard confirmation signal is omitted. A user confirmation element may be displayed that directs the user to scan results when the user confirms. In some instances, if the charger is plugged in from the battery low screen, the device will transition to the results screen.

<i>PC link</i> / <i>Data Transfer Interface</i>

0121<figref idref="f0007"><b>FIG. 5F</b></figref> illustrates a method 200 for linking an analyte monitoring device to a PC and transferring data between the two, according to one embodiment. At block 202, the device is connected to the PC via a wired or wireless connection, and data is transferred between the device and the PC. When data is being transferred, a data transfer screen is displayed and indicates that the data transfer is in process. The example shown also instructs the user not to unplug the device from the computer. If the data transfer completes or the connection between the device and PC (e.g., USB connection) is disconnected, then the home screen is displayed. In one embodiment, if the initial Reader settings have not been saved the Reader will go to the First Start procedure after attempting to transfer data. It should be appreciated that engineering implementation may dictate changes to these screens in other embodiments, In some instances, if the device is plugged into a computer before initial setup, the language will default to English until it is set by PC App.

<i>Charging Battery Interface</i>

0122<figref idref="f0007"><b>FIG. 5G</b></figref> illustrates a method 210 for charging a battery for an analyte monitoring device, according to one embodiment. The device may be charged by connecting the device to a PC or other device (e.g., via a USB connection, etc.) or by connecting the device to an AC adapter that is plugged into an AC outlet, for example.

In one embodiment, while charging every screen is subject to a standard time-out period, such as a 60 second time-out period for instance.

0123If the device is disconnected from the charger (e.g., from the USB connection port), shown at 216, then the home screen continues to be displayed without the charging symbol or icon. This may be replaced by an icon or symbol indicating the current state of the battery life. In one embodiment, if the device is displaying any screen, including the home screen, it will remain on that screen when the charger is disconnected, and the predetermined timeout period will reset when the charger is disconnected.

<u>Home Screen</u>

0124An exemplary embodiment of a graphical user interface which may be utilized in connection with a reader as described herein and which functions to navigate the device in relation to the Home screen is provided.

<i>Sensor Scan or System Check Interface</i>

0125<figref idref="f0008"><b>FIG. 6A</b></figref> illustrates a method 220 for performing a sensor scan or system check, according to one embodiment. From the home screen at block 222, if a glucose check is initiated, it is determined if a system check is required, as shown at block 230. If so, then a system check is performed, as shown at block 232. If a system check is not required, then a sensor scan prompt is displayed, as shown at block 234. The home screen may enable other features to be initiated as well. For example, a readers summaries menu screen may be displayed when the corresponding icon is triggered at the home screen, as shown by block 224. Also, a settings screen may be displayed when the corresponding icon is triggered at the home screen, as shown by block 226.

0126In addition, an insulin on board screen may be displayed when the corresponding icon is triggered at the home screen, as shown by block 236. The insulin on board screen provides information related to the estimated active insulin remaining in a user's body according to insulin data previously entered. Additional details may be provided when a corresponding icon is initiated from the insulin on board screen. In one embodiment, a timer counts down from time of dose for insulin duration as set in a calculator setup. In one embodiment, the insulin on board screen with active countdown appears if the insulin on board is enabled in the calculator setup and the insulin on board is calculated to be present. The icon shown provides a visual indication that reflects the amount of rapid-acting insulin estimated to be still in body-e.g., a percentage of the body-shaped icon filled corresponding to a percentage of the active insulin remaining in the body.

0127Also, a reminder screen may be displayed when the corresponding icon is triggered at the home screen, as shown by block 228. In one embodiment, when a reminder is set, the time at which the alarm will sound appears next to a reminders icon. If, for example, multiple reminders are active, the time shown is the time of the reminder that will sound soonest.

<i>Expired</i>/<i>No Sensor Interface</i>

0128<figref idref="f0009"><b>FIG. 6B</b></figref> illustrates a method for activating a sensor, according to one embodiment. In the embodiment shown, the home screen 242 indicates that no sensor is currently paired to the analyte monitoring device is displayed on the device. For example, a sensor may have never been paired to the device, or a previously paired sensor may have expired. From home screen 242, the user may trigger the activation of a sensor by pressing or otherwise selecting a corresponding icon or other trigger element displayed on the display of the device.

<i>Sensor Warming Up Interface</i>

0129<figref idref="f0009"><b>FIG. 6C</b></figref> illustrates a method 246 for activating a sensor, according to one embodiment. After a user initiates the activation of a sensor, e.g., as represented by block 250, the device may indicate if the sensor is warming up. As illustrated, during the warm up period, the home screen 248 indicates that the sensor is warming up. For example, home screen 248 indicates the time remaining before the sensor is ready, as shown in screen 248-e.g., "Ready in 60 min".

<i>Sensor Near Expiration Interface</i>

0130<figref idref="f0009"><b>FIG. 6D</b></figref> illustrates a method 252 for scanning a sensor if the sensor is nearing expiration, according to one embodiment. In the embodiment shown, a screen 254 indicates the time remaining before the currently paired sensor is expired-e.g., in 16 hours. From home screen 254, the user may still trigger the activation of a sensor by pressing or otherwise selecting a corresponding icon or other trigger element displayed on the display of the device, since the sensor is not yet expired.

<u>Sensor Activation</u>

0131An exemplary embodiment of a graphical user interface which may be utilized in connection with a reader as described herein and which functions activate the sensor is provided.

0132<figref idref="f0010 f0011"><b>FIG. 7</b></figref> illustrates a method 260 for activating a sensor after the device is powered on, according to one embodiment. At block 262, the device is powered on. Once powered, a home screen 264 is displayed. The home screen 264 indicates that there is no active sensor, and further includes an icon or other trigger element 265 that enables the start of a new sensor. Once icon 265 is selected by the user, as represented by block 266, a "Start New Sensor" screen 268 for starting the sensor is displayed. The start new sensor screen 268 enables the user to start a new sensor-e.g., by informing the user to scan the sensor to start it. The user may then scan a sensor to start a pairing, as indicated by block 270. If an expired sensor is scanned, the device may display a screen indicating the sensor is expired. If the scan fails, the device may display a screen informing the user that the scan failed.

0133In some instances, the device may include a masked mode that enables the user to take readings of a paired sensor, but does not display the resulting readings to the user, or otherwise limits the resulting data to the user. As shown by reference pathway B, after a non-expired sensor has been successfully scanned, the device may display a masked mode screen to indicate or configure a masked mode. For example, masked mode screen 272 indicates that the device will operate in the masked mode, unless otherwise changed by the user. Screen 272 enables the user to make a selection and be taken to a settings screen to edit the masked mode setting, as shown at block 274. In some instances, the initial configuration may be set up by the doctor or other health care profession for the patient. If the user wishes to remain in the masked mode, then it may be determined if the sensor has been already activated, as shown at block 276.

0134If the sensor has not been previously activated by another analyte monitoring device, then a warmup message screen 282 is displayed that indicates that the sensor is warming up. The remaining time may also be displayed. If the user confirms the message, for example by selecting the "ok" icon, then the home screen 284 is displayed and indicates the sensor is warming up-e.g., by showing the remaining time until the sensor is ready. If the user attempts to perform a sensor scan as shown by block 286-e.g., by selecting the check glucose icon, then the warmup message screen 282 is displayed again. In some instances, the home screen may be displayed after a predetermined time showing the warmup message, after the sensor is ready, etc.

0135Referring back to block 276, if the sensor has already been activated by another device, then a screen 278 indicating that the sensor is already paired with another device is displayed. Upon user confirmation, the home screen is displayed, as shown at block 280.

<u>Sensor Scan and Results</u>

0136Exemplary embodiment of a graphical user interfaces which may be utilized in connection with a reader as described herein and which function to scan and to provide results are provided.

<i>Sensor Scan Interface</i>

0137<figref idref="f0012 f0013 f0014 f0015"><b>FIG. 8</b></figref> illustrates a method 290 for scanning a sensor with an analyte monitoring device, according to one embodiment. At block 292, the device is powered on. A scan prompt screen 294 is displayed and indicates to the user to scan the sensor to check an analyte level (e.g., glucose level).

0138In the embodiment shown, an icon or trigger element is provided on screen 294 for going to the home screen 296. If selected by the user, the home screen 296 is displayed. From the home screen 296, the user may initiate a sensor scan thereafter and return to the scan prompt screen 294.

0139If a sensor is scanned, as shown at block 298, it is determined if the scan is successful, as shown at block 300. If the scan is not successful, it is determined whether there was an error or whether the sensor was deactivated, as shown at block 302. If there was an error, then a scan error screen 304 is displayed indicating to the user that an error occurred. If the sensor was deactivated, then a start sensor again screen 306 may be displayed to enable the user to restart the sensor. If it is determined that the sensor has fallen out, then a sensor fall out screen 308 is displayed and indicates that the sensor may have fallen loose and that a new sensor may be required. Screens 304, 306, and 308, provide a user confirmation element-e.g., an "ok" element. Upon selection, the home screen 296 is displayed.

0140Returning to block 300, if the scan is successful, then it is determined whether the sensor is new and has not been previously activated, as represented by reference pathway C and block 310. If the sensor is a new inactive sensor, then a new sensor detected screen 312 is shown and indicates that the sensor is a new sensor. Screen 312 provides the user with an option to start the new sensor or not. If the user elects to start the new sensor, then the device initiates the sensor activation process, as shown by block 316. If the user elects to not start the new sensor, then the device displays the home screen, as shown by block 314.

0141Returning to block 310, if the scanned sensor is determined to not be a new inactive sensor, then it is determined if the sensor is the current sensor paired with the device, as shown at block 318. If the sensor is not the current sensor for the device, and is instead already paired with another device, then a screen 320 is displayed that indicates that the sensor is already in use with another device and is not the current sensor for this device. Upon user confirmation, the home screen is displayed, as shown at block 322. If at block 318, it is determined that the sensor is the current sensor paired with the device, then it is determined if the sensor is expiring within a predetermined amount of time-e.g., 3 days in the embodiment shown-as shown by block 324. It should be appreciated that the amount of time may vary in other embodiments, and in one embodiment check to see if the sensor is expired. It should also be appreciated that the predetermined amount of time may be preprogrammed in manufacturing, and/or set within the settings, etc.

0142If at block 324, it is determined that the sensor is expiring within the predetermined amount of time, then a sensor near expiration screen 326 is displayed to indicate the sensor is close to expiring. The remaining time until the sensor expires may be displayed, for example.

0143If at block 324, it is determined that the sensor is not expiring within the predetermined amount of time, then it is determined whether the sensor battery is low, as represented by reference pathway D and block 328. If the battery is low, then at block 330, the device indicates that the battery is low-e.g., via a low battery screen, or a low battery icon, etc. In some instances, a reading is not taken and no results are shown for the scan.

0144If the battery is not low, then at block 332, it is determined if the skin temperature is too hot or cold-e.g., using a "safe" range of temperatures. The sensor may provide the temperature data to the device. If the temperature is determined to be too hot or cold, then the device displays the resulting reading and indicates that the sensor temperature was too hot or too cold, respectively, as shown at block 334.

0145If the skin temperature is not too hot or cold, then it is determined whether the resulting reading is out of range, as shown at block 336.

0146If the sensor is out of range, then it is determined if a high or low glucose condition has occurred, as shown at block 340. For example, a target range or acceptable range may be preset by the manufacturer or customizable by the user. If a high or low condition is present, then the user is taken to the Sensor Results screen and the high or low condition may be indicated on the Sensor Results screen (e.g., via a message, icon, etc.) along with the sensor results, as shown at block 342.

0147If a high or low condition is not present, then it is determined whether a high or low condition is projected, as shown at block 344. A high or low condition may be projected, for example, by trends in the measurement readings. If a high or low condition is projected, then the user is taken to the Sensor Results screen and the projected high or low condition is indicated on the Sensor Results screen along with the sensor results, as shown at block 346.

0148In some instances, the device is programmed such that the skin temperature test takes priority over other test conditions (e.g., out-of-range test, high/low glucose test, projected high/low glucose test, etc.) that may occur simultaneously.

<i>Consecutive Scans Interface</i>

0149An exemplary embodiment of a graphical user interface which may be utilized in connection with a reader as described herein and which functions to provide navigation when consecutive scans are present is provided.

Two Scans within Predetermined Period of Time

0150In some aspects, the analyte reader device is programmed to perform specific navigations when the device is scanned multiple times within a predetermined period of time.

0151<figref idref="f0016"><b>FIG. 9A</b></figref> illustrates a method 350 for performing two scans within a predetermined period of time with the analyte reader, according to one embodiment. After the first scan is performed, a Sensor Results screen is displayed, as shown at block 352. If the power is turned off or the Sensor Results screen is left before a predetermined period of time (e.g., 3 minutes in the example embodiment shown), the results from the first scan are saved, as represented by block 354. If the device is powered back on, or another scan is attempted, within the predetermined period of time, the device will prevent the user from performing a new scan and display a No New Scan screen indicating that the a new sensor reading is not available at this time., as shown by blocks 356 and 358. The No New Scan screen may also indicate the time remaining until another scan, as well as, enable the user to view the last Sensor Results screen if desired, as represented by Sensor Results screen 362.

Device Timeout at the Suggest Dose Screen from BG Result

0152In some aspects, the analyte reader device is programmed to return to a saved suggested dose screen if the reader is powered off or leaves a "Calculator/Suggested Dose" screen when a dose has been calculated but not logged, and the device is powered back on or another scan is attempted within a predetermined period of time.

0153<figref idref="f0017"><b>FIG. 9B</b></figref> illustrates a method 364 of logging a dose calculation, according to one embodiment. After a glucose reading is taken, a "Calculator/Suggested Dose" (CALC SGTD) screen 366 may be displayed to calculate and log a suggested dose of insulin. From screen 366, the user can adjust the suggested does if desired and log the dose. However, if within a predetermined period of time (e.g., 3 minutes in the embodiment shown), the device is powered off, or screen 366 is left, after a suggested dose has been calculated but not logged, then the suggested dose data is saved, as shown at block 368. If the device is powered back on, or another glucose scan is attempted, within the predetermined period of time, as shown by block 370, then the user is returned to the CALC SGTD screen 372 having the saved suggested dose data. From here, the user may continue with the dose calculation and log the calculated dose. If a dose is logged at this point, the dose is stored within the Logbook along with the test results. In one embodiment, the dose is logged as having been taken at the time the test was taken rather than at the time the dose was actually logged. The insulin in body countdown, however, starts from the time at which the does is actually logged.

Suggested Dose from BG Result Logged

0154In some aspects of the present disclosure, after a first scan and calculated insulin dose logged, the device is programmed to prevent a second scan within a predetermined period of time from a first scan. The user will not be able to perform the second scan, but will be able to view the Logbook.

0155<figref idref="f0018"><b>FIG. 9C</b></figref> illustrates a method 374 for enabling two consecutive scans, according to one embodiment. At block 376, the reader is powered off, or the Sensor Results screen is left, within a predetermined period of time after a first scan was taken (e.g., 3 minutes in the embodiment shown). If the device is powered back on, or another scan is attempted, within the predetermined period of time from the first scan, as shown at block 378, then the second scan is prevented from occurring until the predetermined period of time has lapsed. A No New Scan screen 380 is displayed indicating that another scan is not currently permitted. In some instances, as shown, screen 380 provides the time remaining until the another scan can be taken. In the embodiment shown, user confirmation form screen 380 takes the user to the Home screen as shown at block 382. Screen 380 may also provide a selection to allow the user to view the last reading in the Logbook, as shown at block 384.

<i>Sensor Results Interface</i>

0156In some aspects of the present disclosure, a graphical user interface is provided that may be utilized in connection with a reader as described herein and which functions generally to provide sensor results.

Results

0157<figref idref="f0019"><b>FIG. 10A</b></figref> illustrates an example Sensor Results screen 388, according to one embodiment. Screen 388 may be provided, for example, after a scan has been successfully performed. The example sensor results screen 388 is shown to include a sensor reading 389a, a graph 389b of glucose readings taken, and various reader/sensor related information, such as a trending arrow, current time, battery life, sensor expiration, etc. A trigger element 389c for navigating to the Notes interface is also provided to take the user to the Notes screen as shown by block 390. It should be appreciated that other combinations of these, and other, features and trigger elements may be included in other embodiments.

0158In one embodiment, graph 389b does not display if the current glucose value is unavailable. Instead, a screen indicating that the glucose results are unavailable is displayed.

0159In one embodiment, graph 389b displays the past resulting readings for a given time period. The total time period may be sectionalized into a first predetermined period of time 389d, and a second predetermined period of time 389f. The second predetermined period 389f is subsequent to the first predetermined period of time 389d and includes more recent readings than the first predetermined period of time389d. For example, in the embodiment shown, at time 10:23pm, graph 389b displays readings in a first predetermined time period 389d of 8 hours (e.g., 2pm to 10pm), and also displays more recent readings within the second predetermined time period 389f of 1 hour (e.g., 10pm to 11pm). As graph 389b is displayed at 10:23pm, readings for the last 23 minutes (e.g., 10pm to 10:23pm) are shown in the second predetermined time period 389f. As subsequent readings are taken, graph 389b will track the readings within the second predetermined time period 389f. Once subsequent readings are taken for the entire second predetermined period of time 389f, the entire plot of readings are shifted in time by the second predetermined period of time 389f (e.g., 1 hour). In other words, once subsequent readings are obtained up to 11pm, the plot of readings from 3pm to 11 pm will shift to the first predetermined period of time 389d, and the second predetermined time period 389f will begin without any readings and start to track subsequent readings between 11pm and 12pm. Once subsequent readings are obtained up to 12pm, then entire plot of readings are again shifted by the second predetermined period of time 389f (e.g., 1 hour), and the process repeats.

0160In one embodiment, when scanning is first started and no data has been obtained for the graph 389b, the graph 389b is not displayed until the device has obtained sensor readings for at least the first predetermined period of time 389d (e.g., 8 hours).

0161Thus, graph 389b begins with readings for at least the entire first predetermined period of time 389d. For example, in one embodiment, this threshold time period is equal to the first predetermined period of time 389d. In another embodiment, the threshold time period is longer than the first predetermined period of time such that sensor readings have been obtained for part or all of the second predetermined period of time.

0162It is appreciated that in other embodiments, a template of the graph may be displayed at first, but no sensor readings are shown on the graph until the device has obtained sensor readings for at least the first predetermined period of time 389d.

<i>Non-Actionable Reading</i>

0163<figref idref="f0019"><b>FIG. 10B</b></figref> illustrates an example Results Non-Actionable screen 388, according to one embodiment. When a scan is performed and the resulting reading is non-actionable, a Results Non-Actionable screen 388 indicates to the user that the result is non-actionable and that the result should be confirmed. For example, a non-actionable result is a reading that is determined to be too high or too low for a therapy treatment, decision, or recommendation to be made-e.g., an insulin calculation. Screen 388 includes a trigger element for providing more information to the user regarding the non-actionable reading. When selected by the user, a Non-Actionable Message screen 396 is provided additional details, recommendations, etc., such as recommending that the user take a test strip measurement before making any treatment decisions. User confirmation (e.g., by touching the "OK" button 396a) will return the user to the previously displayed Results screen.

<i>Results</i> - <i>Masked Mode</i>

0164<figref idref="f0019"><b>FIG. 10C</b></figref> illustrates an example Results - Masked screen 398, according to one embodiment. When a scan is performed while the device is set for the Masked Mode, a Results - Masked screen 398 is displayed and indicates to the user that the reading was successful. Screen 398 does not provide the resulting reading to the user. The resulting reading is stored along with resulting readings from other scans in the device. These stored readings can later be accessed by a physician or other health care professional at a later time. For example, the physician or HCP may download the data during the next patient visit (e.g., via a wired or wireless connection between the reader and the physician's or HCP's computer,); or the data may be transferred via the internet from the reader (or patient's PC) to the physician's or HCP's computer or server; etc.

<i>Sensor Temperature (Too Hot</i> / <i>Too Cold)</i>

0165<figref idref="f0020"><b>FIG. 10D</b></figref> illustrates an interface for indicating that the sensor temperature is too high, according to one embodiment. The Results Sensor Temp High screen 402 is displayed to indicate to the user that the sensor temperature is too high, such as with respect to a predetermined "safe" range of temperatures. For example, screen 402 may have a warning message and/or icon indicating a high sensor temperature and may further indicate that a glucose reading is not available, as shown. Screen 402 provides a trigger element 402a for providing additional information regarding the high sensor temperature. For example, when the user touches the touch-sensitive button 402a, another screen 404 is displayed to provide additional details or information, such as that the sensor temperature is too high and that the user should try again later.

0166<figref idref="f0020"><b>FIG. 10E</b></figref> illustrates an interface for indicating that the sensor temperature is too low, according to one embodiment. The Results Sensor Temp Low screen 406 is displayed to indicate to the user that the sensor temperature is too low, such as with respect to a predetermined "safe" range of temperatures. For example, screen 406 may have a warning message and/or icon indicating a low sensor temperature and may further indicate that a glucose reading is not available, as shown. Screen 406 provides a trigger element 406a for providing additional information regarding the high sensor temperature. For example, when the user touches the touch-sensitive button 406a, another screen 408 is displayed to provide additional details or information, such as that the sensor temperature is too high and that the user should try again later.

<i>Out of Range High</i>/<i>Low Readings</i>

0167<figref idref="f0021"><b>FIG. 10F</b></figref> illustrates an interface for indicating that the sensor reading is out of range, according to one embodiment. The Results Sensor HI screen 412 is displayed to indicate to the user that the sensor reading is too high and out of range of readings. Instead of a sensor reading being displayed, screen 412 displays an indicator element 412a, such as a message, icon, symbol, etc. For example, in the embodiment shown, the term "HI" 412a is shown in place of a sensor reading to indicate that the reading is out of range and too high.

0168The predetermined upper threshold reading value may be determined based on a predetermined number (e.g., 500 mg/dL), or may be determined relative to a predetermined "acceptable" range of readings to display (e.g., 40 mg/dL to 500 mg/dL), or with respect to a target range (e.g., 350 mg/dL over the target range), etc.

0169Screen 412 may also include a graph 412b of sensor readings that also indicates a target range 412D. Screen 412 provides a trigger element 412c for providing additional information, warning, instructions, etc., regarding the out of range and high sensor reading. For example, when the user touches the touch-sensitive button 412c, another screen 414 is displayed to provide additional details or information, such as that the glucose level is out of range high, that a high glucose level may be dangerous, and that the user should check again later and treat as recommended by their health care professional. Upon user confirmation (e.g., via selection of the "OK" button) the user is taken back to screen 412.

0170<figref idref="f0021"><b>FIG. 10G</b></figref> illustrates an interface for indicating that the sensor reading is out of range, according to one embodiment. The Results Sensor LO screen 416 is displayed to indicate to the user that the sensor reading is out of range and too low. Instead of a sensor reading being displayed, screen 416 displays an indicator element 416a, such as a message, icon, symbol, etc. For example, in the embodiment shown, the term "LO" 416a is shown in place of a sensor reading to indicate that the reading is out of range and too low.

0171The predetermined lower threshold reading value may be determined based on a predetermined number (e.g., 40 mg/dL), or may be determined relative to a determined "acceptable" range of readings to display (e.g., 40 mg/dL to 500 mg/dL), or with respect to a target range (e.g., 20 mg/dL below the target range), etc.

0172Screen 416 may also include a graph 416b of sensor readings that also indicates a target range 416D. Screen 416 provides a trigger element 416c for providing additional information, warning, instructions, etc., regarding the out of range and low sensor reading. For example, when the user touches the touch-sensitive button 416c, another screen 418 is displayed to provide additional details or information, such as that the glucose level is out of range low, that a low glucose level may be dangerous, and that the user should check again later and treat as recommended by their health care professional. Upon user confirmation (e.g., via selection of the "OK" button) the user is taken back to screen 416.

For example, when the user touches the touch-sensitive button 588b, another screen 590 or 592 is displayed to provide additional details or information, such as that the device temperature is too low or too high, respectively, and that the user should try again later.

0222Results Ketone Temp High1/Low1 screen 594 is an example interface that is displayed when a ketone test measurement is available, but also indicates to the user that the device temperature is either high or low, such as with respect to a predetermined "safe" range of temperatures. For example, screen 594 displays the resulting test measurement 594a and also displays a warning message and/or icon 594b indicating a high or low device temperature. Icon 502b also serves as a trigger element for providing additional information regarding the high or low device temperature. For example, when the user touches the touch-sensitive button 502b, another screen 598 or 596 is displayed to provide additional details or information, such as that the device temperature is too low or too high, respectively, and that the user should try again later.

Out of Range High Screen

0223<figref idref="f0036"><b>FIG. 14D</b></figref> illustrates an interface for indicating that the measurement reading is out of range, according to one embodiment. The Ketone Results Out of Range High screen 602 is displayed to indicate to the user that the ketone measurement reading is too high and out of range of readings. Instead of a ketone measurement reading being displayed, screen 602 displays an indicator element 602a, such as a message, icon, symbol, etc. For example, in the embodiment shown, the term "HI" 602a is shown in place of a measurement reading to indicate that the reading is out of range and too high.

0224The predetermined upper threshold reading value may be determined based on a predetermined number, or may be determined relative to a predetermined "acceptable" range of readings to display, or with respect to a target range, etc.

0225Screen 602 provides a trigger element 602b for providing additional information, warning, instructions, etc., regarding the out of range and high ketone measurement reading. For example, when the user touches the touch-sensitive button 602b, another screen 604 is displayed to provide additional details or information, such as that the ketone level is out of range high, that a high ketone level may be dangerous, and that the user should check again later and treat as recommended by their health care professional. Upon user confirmation (e.g., via selection of the "OK" button) the user is taken back to screen 602.

High Ketones Screen

0226<figref idref="f0037"><b>FIG. 14E</b></figref> illustrates an interface for indicating that the ketone measurement reading is high, according to one embodiment. The Ketone Result - High Ketones screen 608 is displayed to indicate to the user that the ketone measurement reading is a high reading, such as via a message, icon, symbol, trigger element, etc., 608c.

0227The predetermined upper threshold reading value may be determined based on a predetermined number, or may be determined relative to a predetermined range of readings, or with respect to a target range, etc.

0228In the embodiment shown, after a high ketone reading is obtained, screen 608 is displayed and the measurement reading 608a is shown. In addition to showing the sensor reading 608a, screen 608 includes a trigger element 608c for indicating the high ketone reading and for accessing additional information, warning, instructions, etc., regarding the high measurement reading. For example, when the user touches the touch-sensitive button 608c, another screen 610 or 612 is displayed to provide additional details or information about the high reading, such as that the ketone level is high, that a high ketone level may be dangerous, and that the user should check again later and treat as recommended by their health care professional. In the embodiment shown, screen 610 is displayed if the ketone reading is between a predetermined range (e.g., .6 to 1.5) and the second screen 612 is displayed if the ketone reading is between a high predetermined range (e.g., 1.6 to 8).

0229Screen 608 may also include an indicator element (e.g., icon, symbol, etc.) 608b that indicates that the measurement reading pertains to a strip test measurement (e.g., ketone test strip measurement). In the embodiment shown, a symbol of a blood drop 608b is used. Screen 608 may also include other trigger elements, such as a trigger element 608e for initiating the Notes interface.

<u>Notes Interface</u>

0230An exemplary embodiment of a graphical user interface which may be utilized in connection with a Reader as described herein and which facilitates a Notes procedure 3000 for entering notes into the logbook is provided. This graphical user interface is now described in greater detail with reference to <figref idref="f0038 f0039 f0040 f0041">FIG. 15</figref>.

0231A graphical user interface which facilitates the Notes procedure 3000 of the reader may include two different notes interfaces; a first notes interface for embodiments where the insulin calculator is disabled 3002, and a second notes interface for embodiments where the insulin calculator is enabled 3004. The Note (Insulin Calculator Disabled) Interface 3002, shown in <figref idref="f0038">FIG. 15A</figref>, begins with the display of an "Add to Logbook" screen 3006. This "Add to Logbook" screen 3006 includes a list of several different notes that may be entered into the Logbook. The list of user selectable notes may include default (e.g., preset notes) and, in some instances, custom (e.g., user-defined) notes. For example, the default notes may include one or more of the following: rapid-acting insulin 3008, long-acting insulin 3010, food 3012, exercise 3014, and medication 3016. The custom notes may include any notes created by the user through the associated informatics software. In some cases, 12 notes may be included in the list of user-selectable notes. For example, 5 default notes and 7 custom notes may be included. In certain embodiments, 4 user-selectable notes are displayed on the touchscreen at once. If there are more than 4 user-selectable notes, the list of notes may be scrolled as necessary to view the list using scroll touchscreen buttons, such as down arrow (e.g., down triangle) touchscreen button 3018 and up arrow (e.g., up triangle) touchscreen button 3020. One or more user-selectable notes may be selected by touching the touchscreen checkbox adjacent the note desired to be selected. Touching a touchscreen checkbox will toggle the checkbox from a checked to unchecked state indicating whether the associated not is selected or not selected, respectively. For instance, the rapid-acting insulin note may be selected by touching the touchscreen checkbox 3022, which then displays a check mark in the touchscreen checkbox to indicate that the rapid-acting insulin note has been selected. The other user-selectable notes may be selected or unselected (e.g., checked or unchecked) as desired in an analogous manner.

0232The selection of notes may be saved by touching the "OK" touchscreen button 3024, which saves the selection of user-selectable notes and returns the graphical user interface to the previous screen. If the "OK" touchscreen button 3024 is pressed without changing the selection of user-selectable notes, then the previous selection of user-selectable notes is retained and saved.

0233In some embodiments, the amount of rapid-acting insulin, long-acting insulin, food, exercise, and medication may be entered by touching the numerical input touchscreen button (e.g., the "1 2 3" touchscreen button) associated with the desired selection. In some cases, the numerical input touchscreen button may not be displayed if the corresponding touchscreen checkbox is not checked, and may only be displayed if the corresponding touchscreen checkbox is checked. For example, when rapid-acting insulin checkbox 3008 is unchecked, the numerical input touchscreen button 3026 for rapid-acting insulin is not displayed. When the rapid-acting insulin checkbox is checked 3022, the numerical input touchscreen button 3026 for rapid-acting insulin is displayed and may be selected.

0234The amount of rapid-acting insulin may be entered by pressing the numerical input touchscreen button 3026 associated with the rapid-acting insulin note selection. Pressing the numerical input touchscreen button 3026 for rapid-acting insulin will cause a numerical input screen 3028 for rapid acting insulin (e.g., the "Enter Rapid-Acting Insulin" screen) to be displayed, as shown by reference path (J) (see <figref idref="f0039">FIG. 15B</figref>). In the numerical input screen 3028 for rapid-acting insulin, the amount (e.g., units) of rapid-acting insulin may be entered. The numerical input screen initially displays no value (e.g., "- -" is displayed in place of any numbers), however, the amount of rapid-acting insulin may be adjusted by pressing the up arrow 3030 (e.g., "+") touchscreen button or the down arrow 3032 (e.g., "-") touchscreen button to increase or decrease, respectively, the amount of rapid-acting insulin as desired. For example, the amount of rapid-acting insulin 3034 may be adjusted by 1 unit increments by tapping the up arrow 3030 or the down arrow 3032. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount of rapid-acting insulin is entered, the amount may be saved by pressing the "OK" touchscreen button 3036, which saves the entered amount of rapid-acting insulin and then returns the graphical user interface to the "Add to Logbook" screen 3006, as shown by reference path (J). Numerical values for long-acting insulin may be entered in an analogous manner by pressing the numerical input touchscreen button 3038 (e.g., the "1 2 3" touchscreen button) associated with the long-acting insulin selection on the "Add to Logbook" screen 3006.

0235Numerical values for food may be entered by pressing the numerical input touchscreen button 3040 (e.g., the "1 2 3" touchscreen button) associated with the food selection on the "Add to Logbook" screen 3006. Pressing the numerical input touchscreen button 3040 for food will cause a numerical input screen 3042 for carbohydrates to be displayed (e.g., the "Enter Carbs" screen), as shown by reference path (J) (see <figref idref="f0039">FIG. 15C</figref>). In the numerical input screen 3042 for food, the amount (e.g., grams) of carbs may be entered. The numerical input screen initially displays no value (e.g., "- -" is displayed in place of any numbers), however, the amount of carbs may be adjusted by pressing the up arrow 3044 (e.g., "+") touchscreen button or the down arrow 3046 (e.g., "-") touchscreen button to increase or decrease, respectively, the amount of carbs as desired. For example, the amount of carbs 3048 may be adjusted by 1 gram increments by tapping the up arrow 3044 or the down arrow 3046. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount of carbs is entered, the amount may be saved by pressing the "OK" touchscreen button 3050, which saves the entered amount of carbs and then returns the graphical user interface to the "Add to Logbook" screen 3006, as shown by reference path (J).

0236In certain embodiments, instead of entering the amount of food as grams of carbs, the amount of food may be entered as servings of carbs, as shown in <figref idref="f0041">FIG. 15E</figref>. In the numerical input screen 3068 for servings of carbs, the screen initially displays no value (e.g., "- -" is displayed in place of any numbers), however, the servings of carbs may be adjusted by pressing the up arrow 3070 (e.g., "+") touchscreen button or the down arrow 3072 (e.g., "-") touchscreen button to increase or decrease, respectively, the servings of carbs as desired. For example, the servings of carbs 3074 may be adjusted by 0.5 serving increments by tapping the up arrow 3070 or the down arrow 3072. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some cases, the numerical input screen 3068 for servings of carbs may include a display of the grams of carbs 3076 that corresponds to the number of servings entered. In some cases, the numerical input screen 3068 for servings of carbs may include a display of the energy (e.g., kcal) of carbs 3078 that corresponds to the number of servings entered. Once the desired servings of carbs is entered, the value may be saved by pressing the "OK" touchscreen button 3080, which saves the entered servings of carbs and then returns the graphical user interface to the "Add to Logbook" screen 3006.

0237Referring back to the numerical input screen 3042 for the amount (e.g., grams) of carbs (see <figref idref="f0039">FIG. 15C</figref>), the numerical input screen 3042 also includes two touchscreen checkboxes configured to allow the selection of reminders to check a user's glucose. For example, the numerical input screen 3042 includes a "1 hr" touchscreen checkbox 3052 and a "2 hr" touchscreen checkbox 3054. None, one or both of the touchscreen checkboxes may be selected as desired. Pressing the "1 hr" touchscreen checkbox 3052 will display a check mark in the "1 hr" touchscreen checkbox 3052 indicating that the "1 hr" touchscreen checkbox 3052 has been selected and will set the Reader to alert the user to check the user's glucose level after 1 hour. Pressing the "2 hr" touchscreen checkbox 3054 will display a check mark in the "2 hr" touchscreen checkbox 3054 indicating that the "2 hr" touchscreen checkbox 3054 has been selected and will set the Reader to alert the user to check the user's glucose level after 2 hours. The check glucose reminder checkboxes may also be displayed on the numerical input screen 3068 for entering the servings of carbs as described above (see <figref idref="f0041">FIG. 15E</figref>).

0238As indicated above, a second notes interface may be provided for embodiments where the insulin calculator is enabled 3004. The Note (Insulin Calculator Enabled) Interface 3004, shown in <figref idref="f0040">FIG. 15D</figref>, begins with the display of an "Add to Logbook" screen 3056. This "Add to Logbook" screen 3056 includes a list of several different notes that may be entered into the Logbook, similar to the "Add to Logbook" screen 3006 in the Note (Insulin Calculator Disabled) Interface 3002 described above. In the "Add to Logbook" screen 3056 of the Note (Insulin Calculator Enabled) Interface 3004, the user-selectable notes (e.g., default and custom notes) may be selected (e.g., checked) or unselected (e.g., unchecked) as desired in an analogous manner as described above in relation to the Note (Insulin Calculator Disabled) Interface 3002. In addition, the numerical input touchscreen buttons (e.g., the "1 2 3" touchscreen buttons) of the Note (Insulin Calculator Enabled) Interface 3004 function in an analogous manner as described above in relation to the Note (Insulin Calculator Disabled) Interface 3002.

0239In the Note (Insulin Calculator Enabled) Interface 3004, the insulin on board and rapid-acting insulin calculator features of the graphical user interface are enabled. For instance, in the Note (Insulin Calculator Enabled) Interface 3004, rather than displaying a numerical input touchscreen button for rapid-acting insulin, a calculator touchscreen button 3058 is displayed with the rapid-acting insulin selection. Pressing the calculator touchscreen button 3058 will cause the graphical user interface to display the Insulin on Board Interface 3060 (see <figref idref="f0042 f0043 f0044">FIG. 16</figref>) and the Insulin Calculator Interface 3062 (see <figref idref="f0045 f0046 f0047 f0048 f0049">FIG. 17</figref>). In some embodiments, if food information (e.g., amount of carbs) is entered as described above, then when the calculator touchscreen button 3058 is pressed, the amount of carbs that was previously entered will automatically be displayed in the corresponding insulin on board and calculator interface screens.

0240In certain embodiments, the Notes - From Logbook Entry Interface 3064 may be displayed from the Logbook Entry screen if the "add or edit notes" touchscreen button is pressed. The Notes - From Logbook Entry Interface 3064 begins with the display of an "Add to Logbook" screen 3066. This "Add to Logbook" screen 3066 includes a list of several different user-selectable notes that may be entered into the Logbook, similar to user-selectable notes described above. In certain embodiments, the "Add to Logbook" screen 3066 of the Notes - From Logbook Entry Interface 3064 does not include a user-selectable note for rapid-acting insulin or food. The other default notes (e.g., long-acting insulin, exercise, medication) and custom notes may still be available for selection by the user as desired.

<u>Insulin on Board Interface</u>

0241As described above, pressing the calculator touchscreen button 3058 from the "Add to Logbook" screen 3056 of the Notes (Insulin Calculator Enabled) Interface 3004, will cause the graphical user interface to display the Insulin on Board Interface 3060 (see <figref idref="f0042 f0043 f0044">FIG.16</figref>). Regarding <figref idref="f0042">FIG. 16A</figref>, in certain embodiments, a user's insulin on board (IOB) information is used in the calculation of a recommended rapid-acting insulin dosage amount. For example, if an insulin dosage has been logged (e.g., logged as a calculated dose, or entered into the logbook as a rapid-acting dose), then the insulin dosage information may be used in the calculation of a recommended rapid-acting insulin dosage amount 3082.

0242In certain embodiments, a user's insulin on board information is used in the calculation of a recommended rapid-acting insulin dosage amount if the user's most recent insulin dose was administered within a certain time period. In some instances, the insulin calculator may be partially locked out if the difference between the current time and the time the most recent rapid-acting insulin was administered is less than a lock out time period (e.g., the most recent insulin dose was administered within a preceding lockout time period, such as within the past 2 hours). During the lockout time period, the insulin calculator may be programmed to only calculate a meal bolus and may not calculate an additional correction bolus 3084. During the lockout time period, the insulin calculator may not include insulin on board into the calculation of a meal bolus.

0243If the difference between the current time and the time the most recent insulin bolus was administered is greater than a threshold time period (e.g., the lockout time period) and less than the duration of insulin action, then the insulin calculator may be programmed to include the user's IOB into the calculation of the recommended rapid-acting insulin dosage amount 3086. In the time period between the end of the lockout time period and the end of the user's duration of insulin action, the insulin calculator may be programmed to determine the recommended rapid-acting insulin dosage amount based on the determined analyte concentration and the insulin on board information. For instance, in the time period between the end of the lockout time period and the end of the user's duration of insulin action, the insulin calculator may be programmed to subtract the user's IOB from the rapid-acting insulin dosage based upon the current glucose concentration level to determine the recommended rapid-acting insulin dosage amount.

0244In certain instances, if the difference between the current time and the time the most recent insulin bolus was administered is greater than the user's duration of insulin action, then the insulin calculator will not include insulin on board into the calculation of a recommended rapid-acting insulin dosage amount 3088. In the time period after the user's duration of insulin action has expired (and before the next dose of insulin is administered), the insulin calculator may assume the user's insulin on board is zero. In the time period after the user's duration of insulin action has expired (and before the next dose of insulin is administered), the insulin calculator may be programmed to determine the rapid-acting insulin dosage amount based on the determined glucose concentration (without including the insulin on board information).

0245Regarding <figref idref="f0043">FIG. 16B</figref>, the Insulin on Board Interface is shown, and begins with a prompt screen 3090 prompting the user with a question asking if the user has forgotten to log any rapid-acting insulin the user has taken since a prior predetermined time point. The prior predetermined time point corresponds to the most recent of either: (a) the current time minus the set insulin duration of action, or (b) the time of the last logged dose of rapid-acting insulin. The prompt screen 3090 has a "Yes" touchscreen button 3092 and a "No" touchscreen button 3094 to select a yes or no answer to the prompted question. If the "No" touchscreen button 3094 is pressed, then the graphical user interface displays the Insulin Calculator Interface 3062 (see <figref idref="f0045 f0046 f0047 f0048 f0049">FIG. 17</figref>). If the "Yes" touchscreen button is pressed, then the graphical user interface displays a numerical input screen 3096 in the Insulin on Board Interface. On the numerical input screen 3096, the amount of rapid-acting insulin that the user has forgotten to log since the prior predetermined time point may be entered. The amount (e.g., units) of rapid-acting insulin may be adjusted by pressing the up arrow 3098 (e.g., "+") touchscreen button or the down arrow 3100 (e.g., "-") touchscreen button to increase or decrease, respectively, the amount of rapid acting insulin as desired. For example, the amount of rapid acting insulin 3102 may be adjusted by 1 unit increments by tapping the up arrow 3098 or the down arrow 3100. In some embodiments, the amount of rapid-acting insulin may be adjusted by 0.5 unit increments (not shown) if the calculator is set to allow half-unit increments. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Numerical input screen may also include a "?" touchscreen button 3104, which, when pressed, provides a help screen 3106 that includes additional instructions to the user. For example, the help screen 3106 may instruct the user to enter the sum total of insulin units that the user has taken over the last X hours that the user has not already logged, where X is the insulin duration of action time. The help screen 3106 may also inform the user that the Reader will use the entered amount of rapid-acting insulin to calculate the user's next rapid-acting insulin dose. The help screen 3106 includes an "OK" touchscreen button 3108, which, when pressed, returns the display to the numerical input screen 3096.

0246On the numerical input screen 3096, once the desired amount of rapid-acting insulin has been entered, the "Next" touchscreen button 3110 may be pressed to advance the graphical user interface to a time input screen 3114, as shown by reference path (M) (see <figref idref="f0044">FIG. 16C</figref>). Alternatively, on the numerical input screen 3096, the "Back" touchscreen button 3112 may be pressed, which returns the graphical user interface to the prompt screen 3090.

0247Regarding <figref idref="f0044">FIG. 16C</figref>, on the time input screen 3114, the display presents a question asking the user how long ago was the unlogged dose of rapid-acting insulin. On the time input screen 3114, the time since the last unlogged rapid-acting insulin dose may be adjusted by pressing the up arrow 3116 (e.g., "+") touchscreen button or the down arrow 3118 (e.g., "-") touchscreen button to increase or decrease, respectively, the time as desired. For example, the time 3120 may be adjusted by 15 minute increments by tapping the up arrow 3116 or the down arrow 3118. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some instances, the default time is 15 minutes (e.g., displayed as "15 minutes or less"). In some cases, the maximum time is the time value set for the insulin duration of action. If the user presses the up arrow 3116 once while the time is at the maximum value, then the time displayed may be shown as "[insulin duration] hours or more", and the up arrow 3116 may be displayed as greyed out and may be un-selectable by the user.

0248The time input screen 3114 also includes a "?" touchscreen button 3122, which, when pressed, provides a help screen 3106 that includes additional instructions to the user as described above and as indicated by reference path (K). The time input screen includes a "Back" touchscreen button 3124, which, when pressed, returns the display to the numerical input screen 3096 as shown by reference path (L). Once the desired time since the last unlogged rapid-acting insulin dose has been entered on the time input screen 3114, the "Next" touchscreen button 3126 may be pressed to advance the graphical user interface to the next screen in the Insulin on Board Interface, such as screen 3128. Pressing the "Next" touchscreen button will save the entered rapid-acting insulin dose with a time stamp reflecting the time calculated based on the interval since the dose was taken as indicated by the user in the previous time input screen 3114. Screen 3128 informs the user that the entered dose of rapid-acting insulin will be used in the calculation of the user's suggested insulin dose, and that the next screen will allow the user to enter what the user plans to eat. Screen 3128 includes a "Back" touchscreen button 3130, which, when pressed, returns the display to the time input screen 3114. Screen 3128 includes a "Next" touchscreen button 3132, which, when pressed, causes the graphical user interface to display the Insulin Calculator Interface 3062 (see <figref idref="f0045 f0046 f0047 f0048 f0049">FIG. 17</figref>).

<u>Insulin Calculator Interface</u>

0249An Insulin Calculator Interface 3062 begins with the display of an "Enter Carbs" screen (see <figref idref="f0046">FIG. 17B</figref>). On the "Enter Carbs" screen, the amount of carbs may be entered. The amount of carbs may be entered as grams, servings, or by meal, depending on the settings of the Reader.

0250For example, the amount of carbs may be entered as grams of carbs on the "Enter Carbs" (grams) screen 3200. The "Enter Carbs" (grams) screen 3200 initially displays no value (e.g., "- -" or "0" is displayed), however, the grams of carbs may be adjusted by pressing the up arrow 3202 (e.g., "+") touchscreen button or the down arrow 3204 (e.g., "-") touchscreen button to increase or decrease, respectively, the grams of carbs as desired, as shown by reference path (T) (see <figref idref="f0047">FIG. 17C</figref>). For example, the grams of carbs 3206 may be adjusted by 1 gram increments by tapping the up arrow 3202 or the down arrow 3204. In some cases, the minimum grams of carbs that may be entered is zero carbs, and the maximum grams of carbs that may be entered is 200 grams of carbs. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. Once the desired amount is entered, the amount may be saved by pressing the "Done" touchscreen button 3208, which saves the entered grams of carbs and then advances the graphical user interface to the Insulin Calculation Interface 3212, as shown by reference paths (S and V) (see <figref idref="f0046">FIGS. 17B</figref>, <figref idref="f0047">17C</figref> and <figref idref="f0049">17E</figref>). The "Enter Carbs" (grams) screen 3200 includes a "Back" touchscreen button 3210, which, when pressed, returns the display to the Results screen.

0251In certain embodiments, the amount of carbs may be entered as servings of carbs on the "Enter Carbs" (servings) screen 3216. The "Enter Carbs" (servings) screen 3216 initially displays no value (e.g., "- -" or "0" or "0.0" is displayed), however, the servings of carbs may be adjusted by pressing the up arrow 3218 (e.g., "+") touchscreen button or the down arrow 3220 (e.g., "-") touchscreen button to increase or decrease, respectively, the servings of carbs as desired, as shown by reference path (T) (see <figref idref="f0047">FIG. 17C</figref>). For example, the servings of carbs 3222 may be adjusted by 0.5 serving increments by tapping the up arrow 3218 or the down arrow 3220. In some cases, the minimum servings of carbs that may be entered is zero servings. In some instances, the serving size may be set to 10 or 12 grams of carbs per serving and the maximum servings of carbs that may be entered is 20 servings. In some instances, the serving size may be set to 15 grams of carbs per serving and the maximum servings of carbs that may be entered is 15 servings. In some embodiments, the amount increases or decreases as appropriate at a slow-rate for the first 2 seconds and at a faster rate after 2 seconds when the up or down arrow is pressed and held. In some cases, the "Enter Carbs" (servings) screen 3216 may include a display of the grams of carbs 3228 that corresponds to the number of servings entered (see <figref idref="f0047">FIG. 17C</figref>). In some cases, the "Enter Carbs" (servings) screen 3216 may include a display of the energy (e.g., kcal) of carbs 3230 that corresponds to the number of servings entered (see <figref idref="f0047">FIG. 17C</figref>). Once the desired amount is entered, the amount may be saved by pressing the "Done" touchscreen button 3224, which saves the entered servings of carbs and then advances the graphical user interface to the Insulin Calculation Interface 3212, as shown by reference paths (S and V) (see <figref idref="f0046">FIGS. 17B</figref>, <figref idref="f0047">17C</figref> and <figref idref="f0049">17E</figref>). The "Enter Carbs" (servings) screen 3216 includes a "Back" touchscreen button 3226, which, when pressed, returns the display to the Results screen.

0252In certain embodiments, the amount of carbs may be entered by meal on the "Enter Carbs" (meal) screen 3232. The "Enter Carbs" (meal) screen 3232 displays a list of meals, such as breakfast, lunch, dinner, or no meal. Each selection includes a corresponding touchscreen radio button. For example, to select the "Dinner" meal, the touchscreen radio button 3234 associated with the "Dinner" selection may be pressed. The "Enter Carbs" (meal) screen 3232 includes a "Back" touchscreen button 3238, which, when pressed, returns the display to the Results screen. The "Enter Carbs" (meal) screen 3232 includes a "Next" touchscreen button 3236, which, when pressed, may advance the graphical user interface to the "Double Check" screen 3240 via reference path (Z), as shown in <figref idref="f0047">FIG. 17C</figref>.

0253The "Double Check" screen 3240 (see <figref idref="f0047">FIG. 17C</figref>) is displayed if the user has marked the same meal since midnight (12:00AM) of the current day. The "Double Check" screen 3240 displays a warning to the user indicating that the user has already logged insulin for the selected meal that day, and asks the user if the user wants to log more insulin for the same meal that day. The "Double Check" screen 3240 includes a "No" touchscreen button, which, when pressed, returns the graphical user interface to the "Enter Carbs" (meal) screen 3232 via reference path (A1). The "Double Check" screen 3240 includes a "Yes" touchscreen button, which, when pressed, advances the graphical user interface to the Insulin Calculation interface 3212 via reference path (Q) (see <figref idref="f0049">FIG. 17E</figref>).

0254Referring again to <figref idref="f0046">FIG. 17B</figref>, the "Enter "Carbs" screens (e.g., the "Enter Carbs" (grams) screen 3200, and the "Enter Carbs" (servings) screen 3216) both include a "?" touchscreen button 3214, which, when pressed, causes the graphical user interface to display help screens 3246, as shown by reference path (O) in <figref idref="f0046">FIG. 17B</figref>, or by reference path (N) in <figref idref="f0047">FIG. 17C</figref>. Help screens 3246 (see <figref idref="f0045">FIG. 17A</figref>) may display information to the user depending on whether the Reader is set to display carbs as grams, servings by grams of carbs, or servings by kcal of carbs. For example, a help screen 3248 may be shown that displays a set of help information to the user regarding carbohydrates when the Reader is set to display carbs as grams. In other instances, the help screen 3250 may be shown that displays a different set of help information to the user regarding carbohydrates as servings by grams of carbs when the Reader is set to display servings by grams of carbs. In other instances, the help screen 3252 may be shown that displays yet a different set of help information to the user regarding carbohydrates as servings by kcal of carbs when the Reader is set to display servings by kcal of carbs. In certain instances, if the help information includes more text than is able to be displayed on a single help screen, the help screen may include a down arrow 3254, which, when pressed, causes the graphical user interface to display the remaining text on a second help screen 3256. The second help screen 3256 includes an up arrow 3258, which, when pressed, returns the graphical user interface to the first help screen 3248, 3250 or 3252 depending on the settings of the Reader as described above. The help screens 3248, 3250, 3252 and 3256 include an "OK" touchscreen button 3260, which, when pressed, returns the graphical user interface to the "Enter "Garbs" screen (e.g., the "Enter Carbs" (grams) screen 3200, or the "Enter Carbs" (servings) screen 3216) from which the help screen was launched, via reference path (P).

0255Referring to <figref idref="f0046">FIG. 17B</figref>, once the desired amount of carbs is entered, the amount may be saved by pressing the "Done" touchscreen button 3208 or 3224, which saves the entered amount of carbs (e.g., grams of carbs or servings of carbs) and then advances the graphical user interface to the appropriate Insulin Calculation Interface 3212, as shown by reference path (S) (see <figref idref="f0049">FIG. 17E</figref>). The Insulin Calculation Interface 3212 displays the suggested dose of insulin based on the amount of carbs entered by the user on the previous screens as described above and/or the user's insulin on board, if any, as described above. The Insulin Calculation Interface 3212 may vary in appearance depending on whether the Reader is set to display whole units of insulin, half units of insulin, or a decimal point or a comma between the whole and half units of insulin.

0256Referring to <figref idref="f0049">FIG. 17E</figref>, in embodiments of the Insulin Calculation Interface 3212 where the Reader is set to display whole units of insulin, the Insulin Calculation Interface 3212 will appear as Suggested Dose screen 3262. Suggested Dose screen 3262 displays the suggested dose of insulin 3264 as units of insulin. The suggested dose of insulin may be adjusted in 1 insulin unit increments by pressing the up arrow 3266 (e.g., "+") touchscreen button or the down arrow 3268 (e.g., "-") touchscreen button to increase or decrease, respectively, the suggested dose of insulin as desired. The minimum and maximum values for the suggested dose of insulin are 0 and 99, respectively. If the suggested dose of insulin is adjusted by the user from its initial value, the amount of units increased or decreased by the user 3270 will be shown below the suggested insulin dose 3264. If the user adjustment of the suggested dose of insulin is calculated to reduce the user's blood glucose below the target range, then the graphical user interface will display a warning screen 3292 that displays a caution to the user that the insulin dose entered may take the user's blood glucose lower than the user's target range and put the user at risk for a low glucose event (see <figref idref="f0048">FIG. 17D</figref>). The warning screen 3292 includes an "OK" touchscreen button, which, when pressed, returns the graphical user interface to the Suggested Dose screen 3262 via reference path (W). The Suggested Dose screen 3262 includes a "Back" touchscreen button 3272, which, when pressed, returns the user to the prior "Enter "Carbs" screen (e.g., the "Enter Carbs" (grams) screen 3200, or the "Enter Carbs" (servings) screen 3216) via reference path (R). The Suggested Dose screen 3262 also includes a "Log dose" touchscreen button 3274, which, when pressed, saves the suggested insulin dose in the logbook along with an associated glucose test result and the time the test was taken (e.g., the insulin dose is not saved as delivered at the time the "Log dose" touchscreen button is pressed) and advances the graphical user interface to the Logbook via reference path (Y) (see <figref idref="f0048">FIG. 17D</figref>).

0257Referring to <figref idref="f0049">FIG. 17E</figref>, in embodiments of the Insulin Calculation Interface 3212 where the Reader is set to display half unit increments of insulin and a decimal point between the whole and half units, the Insulin Calculation Interface 3212 will appear as Suggested Dose screen 3276. Suggested Dose screen 3276 displays the suggested dose of insulin 3278 as units of insulin in 0.5 unit increments. The suggested dose of insulin may be adjusted in 0.5 insulin unit increments by pressing the up arrow 3280 (e.g., "+") touchscreen button or the down arrow 3282 (e.g., "-") touchscreen button to increase or decrease, respectively, the suggested dose of insulin as desired. The minimum and maximum values for the suggested dose of insulin are 0 and 50, respectively. If the suggested dose of insulin is adjusted by the user from its initial value, the amount of units increased or decreased by the user 3284 will be shown below the suggested insulin dose 3278. If the user adjustment of the suggested dose of insulin is calculated to reduce the user's blood glucose below the target range, then the graphical user interface will display a warning screen 3292 that displays a caution to the user that the insulin dose entered may take the user's blood glucose lower than the user's target range and put the user at risk for a low glucose event (see <figref idref="f0048">FIG. 17D</figref>). The warning screen 3292 includes an "OK" touchscreen button, which, when pressed, returns the graphical user interface to the Suggested Dose screen 3276 via reference path (W). The Suggested Dose screen 3276 includes a "Back" touchscreen button 3286, which, when pressed, returns the user to the prior "Enter "Carbs" screen (e.g., the "Enter Carbs" (grams) screen 3200, or the "Enter Carbs" (servings) screen 3216) via reference path (R). The Suggested Dose screen 3276 also includes a "Log dose" touchscreen button 3288, which, when pressed, saves the suggested insulin dose in the logbook along with an associated glucose test result and the time the test was taken (e.g., the insulin dose is not saved as delivered at the time the "Log dose" touchscreen button is pressed) and advances the graphical user interface to the Logbook via reference path (Y) (see <figref idref="f0048">FIG. 17D</figref>).

0258Referring to <figref idref="f0049">FIG. 17E</figref>, in embodiments of the Insulin Calculation Interface 3212 where the Reader is set to display half unit increments of insulin and a comma between the whole and half units, the Insulin Calculation Interface 3212 will appear as Suggested Dose screen 3290. The functions of Suggested Dose screen 3290 are analogous to those described for Suggested Dose screen 3276 above.

0259If the insulin calculator of the Reader determines that no insulin dose is suggested, then the Insulin Calculation Interface 3212 will be displayed as No Suggested Dose screen 3298, which displays information indicating that based on the user's current glucose level, no rapid-acting insulin is being suggested. The No Suggested Dose screen includes a "Back" touchscreen button 3300, which, when pressed, returns the user to the prior "Enter "Carbs" screen (e.g., the "Enter Carbs" (grams) screen 3200, or the "Enter Carbs" (servings) screen 3216) via reference path (R). The No Suggested Dose screen 3298 includes a "Next" touchscreen button 3302, which, when pressed, advances the graphical user interface to Suggested Dose screen 3304. Suggested Dose screen 3304 begins by displaying a suggested does of insulin 3306 as 0 units of insulin. The suggested dose of insulin may be adjusted in 1 unit or 0.5 insulin unit increments, depending on the Reader settings, by pressing the up arrow 3308 (e.g., "+") touchscreen button or the down arrow 3310 (e.g., "-") touchscreen button to increase or decrease, respectively, the suggested dose of insulin as desired. If the suggested dose of insulin is adjusted by the user from its initial value, the amount of units increased or decreased by the user will be shown below the suggested insulin dose 3306. If the user adjustment of the suggested dose of insulin is calculated to reduce the user's blood glucose below the target range, then the graphical user interface will display a warning screen 3292 that displays a caution to the user that the insulin dose entered may take the user's blood glucose lower than the user's target range and put the user at risk for a low glucose event (see <figref idref="f0048">FIG. 17D</figref>). The warning screen 3292 includes an "OK" touchscreen button, which, when pressed, returns the graphical user interface to the Suggested Dose screen 3304 via reference path (W). The Suggested Dose screen 3304 includes a "Back" touchscreen button 3312, which, when pressed, returns the user to the prior No Suggested Dose screen 3298. The Suggested Dose screen 3304 also includes a "Log dose" touchscreen button 3314, which, when pressed, saves the suggested insulin dose in the logbook along with an associated glucose test result and the time the test was taken (e.g., the insulin dose is not saved as delivered at the time the "Log dose" touchscreen button is pressed) and advances the graphical user interface to the Logbook via reference path (Y) (see <figref idref="f0048">FIG. 17D</figref>).

0260Suggested Dose screens 3262, 3276, 3290 and 3304 include a "Dose details" touchscreen button 3294 (e.g., an "i" touchscreen button), which, when pressed, causes graphical user interface to display Dose Details Interface via reference path (X) (see <figref idref="f0048">FIG. 17D</figref>).

0261Dose Details Interface 3296 is shown in <figref idref="f0050">FIGS. 18A</figref> and <figref idref="f0051">18B</figref>. Dose Details Interface begins a Dose Details screen (e.g., 3316, 3318 and 3320) that displays a summary of the calculated insulin dose. The Dose Details screen (e.g., 3316, 3318 and 3320) may have various appearances depending on the settings of the Reader (e.g., whether the Reader is set to display carbs as grams of carbs, servings of carbs, or by meal) and the data input by the user or calculated by the Reader (e.g., amount of carbs, insulin on board, user adjustment to the suggested dose of insulin, etc.). The Dose Details screen displays the amount of carbs by meal 3322, as grams of carbs 3324, or as servings of carbs 3326. If insulin correction is enabled on the Reader, the Dose Details screen will display the suggested insulin dose 3328. If insulin correction is disabled on the Reader (e.g., the Easy setup sets "no correction insulin") then the suggested insulin dose is not displayed. If the Reader determines that insulin on board is present, then the Dose Details screen displays the amount of insulin on board 3330. In the Reader determines that no insulin on board is present, then the amount of insulin on board is not displayed. If the user adjusted the suggested insulin dose, the Dose Details screen will display the amount the user adjusted the suggested insulin dose 3332. Based on the above data, the Dose Details screen displays the calculated insulin dose 3334.

0262The Dose Details screen includes a down arrow touchscreen button 3336, which, when pressed, advances the Dose Details screen to the second page of the Dose Details screen via reference path (B1) (see <figref idref="f0051">FIG. 18B</figref>). The information displayed on the second page of the Dose Details screen may vary depending on whether insulin on board is present and whether the suggested dose of insulin only accounts for carbs in the user's meal. If insulin on board is not present, then the second page of the Dose Details screen 3338 displays information indicating that the suggested dose of rapid-acting insulin covers the carbs in the user's meal and corrects for the user's current glucose level. If insulin on board is present and the user has taken insulin within the past 2 hours, then the second Dose Details screen 3340 displays information indicating that the user has taken rapid-acting insulin in the past 2 hours, and the suggested dose of insulin covers the carbs in the user's meal but does not correct for the user's current glucose level. If insulin on board is present and the time when the user has last taken insulin is more than 2 hours from the current time but less than the duration of insulin action, then the second Dose Details screen 3342 displays information indicating that the user has taken rapid-acting insulin in the past 4 hours, and the suggested dose of insulin covers the carbs in the user's meal, corrects for the user's current glucose level, and accounts for insulin that was previously logged. The second Dose Details screen (e.g., 3338. 3340 and 3342) include an up arrow touchscreen button 3344, which, when pressed, returns the graphical user interface to the previous Dose Details screen.

<u>Reminders Interface</u>

0263An exemplary embodiment of a graphical user interface which may be utilized in connection with a Reader as described herein and which facilitates a Reminders procedure 3400 for setting reminders is provided. This graphical user interface is now described in greater detail with reference to <figref idref="f0052 f0053 f0054 f0055">FIG. 19</figref>.

0264The Reminder Interface 3400, shown in <figref idref="f0052">FIG. 19A</figref>, begins with the display of a Home Screen 3402 of the Reader. The Home Screen includes a reminders touchscreen button 3404 (e.g., a bell shaped icon, an alarm clock icon, a clock icon, etc.), which, when pressed, begins the procedure to set and/or adjust reminders. If a reminder has been previously set, then next reminder time 3406 is displayed next to the reminders touchscreen button 3404.

<u>Receive Reminders Interface</u>

0272An exemplary embodiment of a graphical user interface which may be utilized in connection with a Reader as described herein and which facilitates a Receive Reminder procedure 3500 for receiving reminders is provided. This graphical user interface is now described in greater detail with reference to <figref idref="f0056 f0057">FIG. 20</figref>.

0273The Receive Reminder Interface 3500, shown in <figref idref="f0057">FIG. 20B</figref>, begins when a reminder (e.g., a reminder that has been set using the Reminders Interface 3400 described above) is activated, such as when the time or triggering event of a scheduled reminder is reached. A scheduled reminder should be displayed when the time / triggering event of the reminder is reached even if the Reader display is off. In certain embodiments, a scheduled reminder is not displayed on the Reader if the time / triggering event of the reminder is reached: (1) During a blood glucose test using a strip - instead the reminder is presented after the results have been displayed; (2) When the battery is critically low - instead the reminder is presented when the battery is sufficiently charged, and the Reader is powered on; (3) During error conditions - instead the reminder is presented the next time the Reader is powered on; or (4) When the Reader is connected to a computer and data transfer is in process - instead the reminder is presented when the data transfer is completed.

0274When the time / triggering event of the reminder is reached, a Reminder screen is 3502 displayed (<figref idref="f0057">FIG. 20B</figref>). The Reminder screen 3502 includes display of the reminder with a reminder icon 3504 representing the type of reminder. For example, the reminder icon may be an "Alarm" reminder icon 3504 (e.g., a picture of a bell or alarm clock, etc.), indicating that the type of reminder is an alarm. In some instances, the reminder icon is a "Take Insulin" reminder icon 3506 (e.g., a picture of a syringe) (see <figref idref="f0056">FIG. 20A</figref>), indicating that the type of reminder is a reminder to the user to take insulin. In some instances, the reminder icon is a "Check Glucose" reminder icon 3508 (e.g., a picture of a glucose Reader) (see <figref idref="f0056">FIG. 20A</figref>), indicating that the type of reminder is a reminder to the user to check their glucose level. Other types of icons and reminders are possible.

0275If the Reminder sound is set to on, a beep sounds with appearance of any reminders screen. If a reminder is ignored, the reminder will appear on the screen with the next power on (whether by hardware button or strip insertion). If multiple reminders are active, the reminder screens will stack up with the most recent reminder showing first. The reminder screens will require dismissal one by one. If daily repeated reminders have been missed, once a new day's reminder is current, the previous day's reminder for that time is no longer active and is not part of the stack-up of reminder screens.

0276The Reminder screen 3502 includes a "Snooze 15 min" touchscreen button 3510, which, when pressed, sets the active reminder to re-active in 15 minutes, and returns the graphical user interface to the next active reminder or, if there are no other active reminders, to the previously displayed screen before the reminder was activated. The Reminder screen 3502 also includes an "OK" touchscreen button 3512, which, when pressed cancels the active reminder and returns the graphical user interface to the next active reminder or, if there are no other active reminders, returns the graphical user interface to the Home Screen.

<u>Reader Summaries</u>

0277In some aspects of the present disclosure, the analyte monitoring device may be programmed with software to provide summaries of information and data related to obtain readings. The software provides an interface to view and manage features related to generated reports. Different types of summaries may be generated. For example, <figref idref="f0058 f0059">FIGS. 21A-D</figref> illustrate various types of interfaces for displaying summaries on the analyte monitoring device, according to certain embodiments. It should be appreciated that the summary screens illustrated are exemplary and should not be interpreted as limiting.

0278An exemplary embodiment of a graphical user interface which may be utilized in connection with a reader as described herein and which functions to provide the user with summaries of information and data related to obtained readings.

<i>Summaries Menu Interface</i>

0279<figref idref="f0058"><b>FIG. 21A</b></figref> illustrates an exemplary interface for providing a summaries menu on the analyte monitoring device. History Menu01 screen 622 is shown in <figref idref="f0058">FIG. 21A</figref> and provides a menu of summary options that the user can select. Option 622a takes the user to a Logbook screen for viewing logged data, as shown by block 626. Option 622b takes the user to a Daily Graph screen which provides a summary of data in a daily graph format. Option 622c provides a screen for averages for glucose readings obtained for a period of time. If more options are available that can fit on a single screen shot, then a trigger element 622h (e.g., an arrow symbol) for scrolling or otherwise viewing the remaining options may be selected. When arrow 622h is selected, the user is taken to screen 624 wherein the remaining options are displayed. For example, option 624 provides a summary screen of low glucose events for a period of time. Option 622d provides a screen showing a summary of time that obtained readings were in the target zone. Option 622f provides a screen showing summarizing information related to the user of the reader device. Option 622g provides a summary screen of daily patterns that have been determined or identified based on reading acquired for a period of time. Trigger element 622i takes the user back to screen 622.

0280When one of the options are selected, it is determined if sensor data is present, as shown at block 628. If no data is present, a No Sensor Data screen 630 is displayed to indicate to the user that no sensor data is available for the summary. In one embodiment, the all summaries except for logbook include sensor data only (e.g., glucose data obtained from the sensor). If the device includes only strip data and insufficient sensor data, then the No Sensor Data screen is still provided when a summary option is selected.

0281If sensor data is provided, then the corresponding screen for the selected summary option is displayed, as represented by reference path T1. From the selected summary screen, the user can navigate back to the menu options screens 622,624 to select another menu option if desired, as shown by reference path S1.

0282<figref idref="f0059"><b>FIG. 21B</b></figref> illustrates a Daily Graph screen 632 for showing a daily graph 632a of sensor readings obtained over a single day or 24 hour time period. For example, graph 632a illustrates the readings obtained on Wednesday, February 22. The horizontal axis of graph 632a represents time throughout the day, while the vertical axis represents sensor reading values. A target zone 632d may also be provided on graph 632 to represent the target zone for readings. Also shown, are event indicators 632b which indicate various events with symbols or icons on the graph 632a. For example, the needle icon represents a logged insulin event indicating that an insulin dose was taken, and the apple icon represents a logged food event indicating that food was eaten. More details may be stored or logged for the given event, and in one embodiment, the event indicators 632b may be selected by the user to provide additional details regarding the event.

0283In the embodiment shown, trigger elements 632c (e.g., left and right arrows) are also provided to enable the user to navigate forwards and backwards to another day or 24-hour time period. For example, the user could navigate to the next day after Wednesday using the right arrow, or go to the previous day by selecting the left arrow.

0284<figref idref="f0060"><b>FIG. 21C</b></figref> illustrates an exemplary Average Glucose Summary interface for providing a graph of sensor readings obtained over a time period that is summarized with respect to a predetermined time period such as single day or 24 hour time period as shown. For example, Average Glucose (GLUC) 01 screen provides a bar graph 634a for sensor readings taken over the last 7 days. The bar graph 634a includes bars for various increments of time throughout a single day. Each bar represents the average glucose reading that was obtained at that increment of time of day for the last 7 days. For example, the average of all the sensor readings obtained between 12am and 6am over the last 7 days, is 121 mg/dL. For 6am to 12, the average glucose reading was 152 mg/dL, etc.

0285Screen 634 also includes an average glucose value 634b for the time period of data. For example, the average glucose reading for all readings obtained over the last 7 days was 119 mg/dL. Screen 634 also includes a trigger element 634c (e.g., an arrow icon) for changing the different time period of obtained data. For example, if the user selects the right arrow icon 634c, the user is taken to AVG GLUC02 screen 636, which similarly displays a bar graph 636a and average glucose value 636b, but for a different time period, such as the last 14 days as shown. Similarly, screen 636 also includes trigger elements 634c for again increasing the time period. In this way, the user can change to AVG GLUC03 screen 638, which similarly displays a bar graph 638a and average glucose value 638b, but for a different time period, such as the last 30 days as shown. Similarly, the user can change to AVG GLUC04 screen 640, which similarly displays a bar graph 640a and average glucose value 640b, but for a different time period, such as the last 90 days as shown. Trigger elements 634c enable the user to navigate forwards and backwards between screens 634,636,638,640 to change the time periods as desired. From any of the screens, user confirmation (e.g., by selecting the "ok" button) will take the user back to the options menu interface 622,624.

0286<figref idref="f0059"><b>FIG. 21D</b></figref> illustrates an exemplary screen for showing the percentage of time the sensor readings were within a target zone. Time In Target screen 642 displays a representation 642a of the percentage of time within a target zone, above a target zone, and below a target zone, for sensor readings obtained for a period of time (e.g., 7 days in the embodiment shown). Trigger element 642c is provided to enable the user to change the time period-e.g., similarly as described in <figref idref="f0060">FIG. 21c</figref>. Representation 642a also includes bar graphs for the associated percentages.

<i>Summaries Menu</i> - <i>Masked Mode Interface</i>

0287<figref idref="f0059"><b>FIG. 21E</b></figref> illustrates an exemplary screen 644 for showing a graph 644a of the number of events associated with sensor readings obtained over a time period, wherein the events are summarized with respect to a predetermined time period, such as single day or 24 hour time period as shown. For example, screen 644 indicates a graph 644a for sensor readings obtained over the last 7 days, wherein 1 event occurred between 12am and 6am, 0 events occurred between 6am and 12pm, 3 events between 12pm and 6am, etc. In the embodiment shown, the event corresponds to a low glucose reading-e.g., with respect to a target zone. Other events may also be implemented-e.g., high glucose readings, insulin dosages, food intake events, etc. Trigger element 644c is provided to enable the user to change the time period.

0288<figref idref="f0059"><b>FIG. 21F</b></figref> illustrates an exemplary screen 648 for indicating information associated with the use of the sensor over a time period. For example, screen 648 indicates the average scans per day, and the number of days with sensor data, for sensor readings obtained over the last 7 days. Similarly, trigger element 648c is provided to enable the user to change the time period.

0289<figref idref="f0058"><b>FIG. 21G</b></figref> illustrates an example interface for providing a summaries menu on the analyte monitoring device, when the device is in masked mode. History Menu Masked screen 620 is shown provides a menu of summary options that the user can select. Option 620a takes the user to a Logbook screen for viewing logged data. Option 620b provides a screen showing summarizing information related to the use of the reader device. Since the device is in masked mode and does not permit the user from viewing sensor readings, summary screens related to obtained readings are also not available.

The standard operation system (OS) installer application is run and the RD software is launched, as shown at block 4012 and 4014.

0381Referring back to block 4004, if the RD software is already installed on the remote device, then it is determined if the RD software is currently running. If so, then the user is taken to the Reader Landing screen at block 4026.

0382If the RD software is not currently running, then it is determined if an auto-launch is enabled to automatically launch the RD software if the analyte monitoring device is coupled to the remote device, as shown at block 4020. If the auto-launch is enabled, then the RD software is launched on the remote device. If the auto-launch is not enabled, then the user may manually launch the software when desired, as shown at block 4022.

0383When the RD software is launched, the software may automatically perform or ask to determine if updates to the software are available, as represented by block 4034. The RD software may, for example, access a server via the internet to determine what updates are currently available, and then compare the version of the software and any previous updates to see if any additional updates are missing. If new updates are not available, then the RD software application continues with the Auto-Assist Startup process to enable the user to use the RD software, as represented at block 4036.

0384If new updates are available, then the Reader Landing screen is displayed, as shown at block 4026. If the user elects not to run the update routines at this time, the RD software application continues with the Auto-Assist Startup process to enable the user to use the RD software, as represented at block 4036. If the user elects to install the updates, then the update routines are run, as shown at block 4024, before continuing on with the Auto-Assist Startup process at block 4036

0385If instead of starting at block 4002, the user launches RD software already installed on a remote device, as shown at block 4028, then it is determined if the analyte monitoring device is coupled to the remote device, as shown at block 4030. If the reader device is not connected, then a Reader Welcome screen is displayed to assist the user as the RD software is running, as shown at block 4032. If the reader is coupled to the remote device, then it is determined if any updates are available as shown and discussed for block 4034.

0386<figref idref="f0100"><b>FIG. 37</b></figref> illustrates a flowchart for the Auto-Assist Startup process 4036, according to one embodiment. As the RD software starts up, it is determined if there is date (e.g., sensor readings) on the reader device, as shown at block 4042. If there is no data on the reader device, then it is determined if the reader device has already been set up, as shown at block 4044. If not, then the user is taken to a Guided Reader Setup - Welcome screen for guiding the user through the reader setup process, as shown at block 4046. If the reader device has been setup before, then it is determined if the reader device and remote device are out of sync (e.g., the time on the Reader device and the remote device are different) If the reader device is out of sync, then a Reader Out of Sync screen is provided, as shown at block 4052, to inform the user and to enable synchronization. If the reader device is not out of sync, then the Reader Landing Screen is displayed, as shown at block 4050.

0387Referring back to block 4042, if sensor reading data is on the reader device, then the data may be downloaded to the remote device, either automatically or upon user confirmation, as shown by block 4054. At block 4054, it is determined if the reader device and remote device are out of sync. If so, then the Reader Out of Sync screen is displayed. If no out of sync, then it is determined if it is the first time creating reports on the remote device, as shown at block 4058., If so, then a Guided Reports Setup - Welcome screen is displayed, as shown at block 4060, to assist the user with setting up reports. If it is not the first time creating reports on the remote device, then it is determined if a quick print feature is enabled to allow quick display and/or printing of predetermined or pre-customized reports. If the quick printing feature is not enabled, then the user is taken to a Create Reports screen to enable the user to create reports, as shown at block 4068.

0388<figref idref="f0101"><b>FIG. 38</b></figref> illustrates an example Welcome screen, according to one embodiment.

Insulin Calculator Setup Interface:

0398An exemplary embodiment of a graphical user interface which may be utilized in connection with Health Management Software for a Reader as described herein and which facilitates a procedure for inputting the insulin calculator settings via the Health Management Software is provided. This graphical user interface is now described in greater detail with reference to <figref idref="f0108 f0109 f0110 f0111 f0112 f0113">FIGS. 43-46</figref>.

0399In some cases, the Health Management Software for the Reader may include programming for two or more types of medication dosage calculators. During setup of the Health Management Software, the Health Management Software may prompt the user and/or the health care professional to select a type of medication dosage calculator (e.g., insulin bolus calculator). The initial selection of the type of medication dosage calculator may be changed as desired by the user or the health care professional. In certain embodiments, the two or more types of medication dosage calculators include two types of bolus calculators. For instance, the two types of bolus calculators can include an easy bolus calculator and an advanced bolus calculator.

0400By "easy calculator", "easy bolus calculator", "simple bolus calculator", "easy insulin calculator" or "simple insulin calculator" is meant a bolus calculator that includes basic features for determining a recommended medication dosage amount, such as a recommended insulin dosage amount. For example, an easy bolus calculator may include algorithms configured to determine a recommended medication dosage amount based on a fixed medication dosage amount. In these instances, the easy bolus calculator may be appropriate for a user that administers a fixed medication dosage amount (e.g., a fixed insulin dosage amount) for each meal. In some embodiments, the easy bolus calculator only takes into account the fixed medication dosage amount when recommending the medication dosage amount to the user, and thus functions as a reminder and/or log for the fixed medication dosage amount.

0401The insulin calculator setup procedure begins on the Insulin Calculator Interface Setup screen 3800, where the user can select an Insulin Calculator On/Off toggle button 3802 to turn the insulin calculator on or off. When the Insulin Calculator On/Off toggle button is selected into the "On" position, the insulin calculator is activated and may be set up as described below. The desired type of insulin calculator (e.g., easy or advanced calculator) can be selected by selecting the insulin calculator selection box 3804, which allows the selection of "Easy" to activate the easy insulin calculator, and "Advanced" to activate the advanced insulin calculator.

0402If the user selects the "Easy" selection in the insulin calculator selection box 3804, the Insulin Calculator Setup Interface screen 3800 displays the set up options for the easy bolus calculator. Set up for the easy bolus calculator is shown in <figref idref="f0108">FIG. 43</figref>.

0403In certain embodiments, the easy bolus calculator may determine a recommended medication dosage amount (e.g., a recommended rapid-acting insulin dosage amount) based on information, such as, but not limited to, a fixed medication dosage amount, a target blood glucose range (e.g., correction target), and an insulin sensitivity (e.g., correction factor). In some instances, the easy bolus calculator may also include information, such as the patient's insulin on board, in the determination of a recommended medication dosage amount. For example, a fixed medication dosage amount may be entered by meal (e.g., breakfast, lunch and dinner).

0404The Insulin Calculator Setup Interface screen 3800 includes amount entry boxes for each meal. A fixed medication dosage amount may be entered into the breakfast amount entry box 3806, the lunch amount entry box 3808 and the dinner amount entry box 3810 as units of insulin. In some embodiments, the correction target range may be entered. The Insulin Calculator Setup Interface screen 3800 includes correction target range amount entry boxes for the minimum target range value 3812 and the maximum target range value 3814. In some embodiments, the Insulin Calculator Setup Interface screen 3800 includes a correction factor amount entry box 3816 in which the insulin sensitivity (e.g., correction factor) may be entered as 1 unit per X mg/dL, where X is the amount entered for the correction factor. In some embodiments, the Insulin Calculator Setup Interface screen 3800 includes radio buttons for enabling or disabling insulin calculator trend correction by selecting either the trend correction enabled radio button 3818 or the trend correction disabled radio button 3820, respectively.

0405If the user selects the "Advanced" selection in the insulin calculator selection box 3824, the Insulin Calculator Setup Interface screen 3822 displays the set up options for the advanced bolus calculator. Set up for the advanced bolus calculator is shown in <figref idref="f0109">FIG. 44</figref>, which shows advanced bolus calculator settings available when the insulin calculator is set to count carbs by grams of carbs.

0406By "advanced calculator", "advanced bolus calculator" or "advanced insulin calculator" is meant a bolus calculator that includes additional information, such as, but not limited to, the amount of carbohydrates consumed, the carbohydrate ratio, a target blood glucose range (e.g., correction target), and an insulin sensitivity (e.g., correction factor), in determining a recommended medication dosage amount (e.g., a recommended insulin dosage amount). For example, rather than using a fixed medication dosage amount for each meal as in the easy calculator, the advanced bolus calculator may use dose determination information entered by the user, such as the amount of carbohydrates consumed, to determine a recommended medication dosage amount. The advanced bolus calculator may also include additional dose determination information into the determination of the recommended medication dosage amount, such as but not limited to, a patient's the current blood glucose level, an amount of exercise, a target analyte concentration (e.g., a target blood glucose range), an insulin sensitivity (e.g., correction factor), a duration of insulin action, a carbohydrate ratio, and insulin on board information, such as an administered medication dose time information, an administered dose frequency information over a predetermined time period, and an administered medication dose amount.

0407The Insulin Calculator Setup Interface screen 3822 includes an "Enter Food By" selection box 3826, which, when selected, allows the user to set the insulin calculator to enter food by grams of carbs or by servings. If "Grams of Carbs" is selected in the "Enter Food By" selection box 3826, then Insulin Calculator Setup Interface screen 3822 displays the set up options for the advanced bolus calculator by grams of carbs.

0408In some embodiments, the carbohydrate ratio may be entered. The Insulin Calculator Setup Interface screen 3822 includes a carbohydrate ratio amount entry box 3828 for entering the amount of the user's carbohydrate ratio as 1 unit per X grams of carbs, where X is the amount entered. In some embodiments, the correction target range may be entered. The Insulin Calculator Setup Interface screen 3822 includes correction target range amount entry boxes for the minimum target range value 3832 and the maximum target range value 3834. In some instances, the correction target may be entered as a single target value rather than a target range by selecting "Single Target" (not shown) from the correction target selection box 3830. In some embodiments, the Insulin Calculator Setup Interface screen 3822 includes a correction factor amount entry box 3836 in which the insulin sensitivity (e.g., correction factor) may be entered as 1 unit per X mg/dL, where X is the amount entered for the correction factor. In some embodiments, the Insulin Calculator Setup Interface screen 3822 includes radio buttons for enabling or disabling insulin calculator trend correction by selecting either the trend correction enabled radio button 3838 or the trend correction disabled radio button 3840, respectively.

0409In certain instances, the carbohydrate ratio, the target range, and/or the correction factor may be entered by time of day, as shown in <figref idref="f0110 f0111">FIG. 45</figref>. To enable the carbohydrate ratio time of day settings, the carbohydrate ratio "By Time of Day" checkbox 3842 may be selected.

0418The Professional Options screen also enables the Masked Mode setup to be viewed and set on the remote device. The setup screen provided functions similar to the Masked Mode setup discussed earlier, except that the setup takes place via the RD software application.

0419<figref idref="f0114"><b>FIG. 47</b></figref> illustrates a Masked Mode setup screen 5090, according to one embodiment. As shown, Masked Mode setup screen 5090 provides a section 5092 in which the user can activate the Masked Mode and set reminders to check glucose at preset intervals. For example, the reminder is reset every time the sensor is scanned. As shown, the menu 5058 of trigger elements for initiating various screens is maintained in the Profile screen 5086.

Reset System:

0420The Professional Options screen also enables the user reset settings of the Reader device. The Reset System interface may permit reset of all settings at once, and/or permit the user to selectively reset specific setting on the device.

0421Referring back to <figref idref="f0102 f0103 f0104">FIG. 39</figref>, at block 4094, the user is taken to a Backups screen where the user can save a backup file of a current Reader setting. In one embodiment, the backup files do not save glucose results or other Reader logbook entries.

0422Thus, from the menu 5058 of trigger elements for initiating various Reader Mode screens, which remains on the various Reader Mode screens to enable quick reference and access to those screens, the user is able to navigate to the desired Reader Mode screen. Once the settings are viewed, edited, or deleted, the user can save the setting to the reader, as shown by reference path X3. At block 4096, a Reader Status screen is displayed to indicate to the user that a save is in progress. In block 4098, a Progress screen is shown to indicate a save to the reader, and after the save the user is taken to a Reader Landing - Settings saved screen to indicate that the save was successful, as shown by block 4100.

0423If changes to any settings in menu 5058 are cancelled, as shown by reference path Y3, or the user navigates away, as shown by reference path A4, then the user is taken to a warming Alert screen to alert the user that changes will be lost, as shown at 4102 via reference path Z3. If changes are cancelled, then the user is navigated back to the Reader Landing screen 4082. If the user elects to save the changes, then to blocks 4096 and 4098 as previous described. If the user elects to not save the settings, then the user is taken to the Reader Landing - Setting saved screen 4100.

0424From the Backups screen, the user can save a backup file, as shown at block 4104. Progress screen 4106 is displayed while the save is in progress. If the save should be cancelled before complete, then the user is taken back to the Backups screen 4108.

0425If the save is determined to be not valid, as shown at block 4105, then the user is taken to an Alert screen 4110 to indicate to the user that a save is not valid. For example, if the filename already exists, then the user can elect to either save it and overwrite the previous file, and will be taken to the Progress screen 4106. If the user elects not to save it, then the user is then back to the Backups screen 4112.

0426From the Backups screen at block 4094, the user can select a backup file to restore, as shown by block 4114 and reference path C4. Once the backup file is selected the user is taken to a Progress screen 4116 that indicates that the backup file is being processed. If the processing of the backup file is determined to not be valid or encounters an error, then the Alert screen 4120 is displayed to indicate that there was an error with the backup file (e.g., that the file is damaged). The user is then taken back to the Backups screen, as shown by block 4122. If the processing of the backup file is valid, then the Restore Reader Setting is displayed to indicate that the Reader settings are being restored to the settings on the backup file. If the restore should be cancelled, then the user is taken back to the Backups screen, as shown by block 4126. If the restore is not cancelled, then the user is taken to either a Reader Status screen 4128, or to a Progress screen 4130 and Backups screen 4132, similarly as described above.

0427<figref idref="f0115"><b>FIG. 48</b></figref> illustrates a method 5100 for a flow for syncing the Reader device when the Reader is coupled to the remote device and determined to be out of sync with the remote device. For example, when out of sync, the time on the Reader is different than the time on the remote device.

0428If the Reader is coupled to the remote device and determined to be out of sync with the remote device, then the Reader Out of Sync screen at 5102 is initiated, as shown by block 5102. An Alert screen is displayed to alert the user of the sync and ask if the user wishes to synch the Reader with the remote device. The user is also taken to the Alert screen at 5106 from the General Reader Settings screen when it is determined that the two devices are out of sync, as shown by block 5104.

0429If the user elects to sync the two devices, then a Reader Status screen at 5108 and Progress screen at 5110 are displayed while the update is in progress. When the update is complete, the user is taken back to the Reader Landing - Reader updated screen, as shown at block 5112.

Guided Reader Setup Flow

0430When a new Reader that has never been used is connected to the remote device, the user is guided through the initial setup of that Reader in a step-by-step fashion. Along the way, basic Reader configuration settings such as name, patient ID, date, time, and language are collected for the purpose of initializing the Reader. In one embodiment, the patient name and ID are optional settings while the date, time, and language options must be set to complete the setup process.

0431<figref idref="f0116"><b>FIG. 49</b></figref> illustrates a method 5100 for a flow for the Guided Reader Setup interface, according to one embodiment. When a new Reader that has never been used is connected to the remote device, the New Reader Welcome screen is displayed to start the guided setup process, as shown at block 5116. The Start/Patient info screen is initiated to receive patient info, as shown at block 5118. The Confirm Date/Time/Language screen is initiated to receive the appropriate entries from the user, as shown at block 5118. Once entered, the Ready to Save screen is initiated to indicate to the user that the entries are to be saved. As the save is in progress, the Reader Status screen at 5130 or the Progress screen at 5128 is displayed. From the Progress screen at block 5128, the Reader Landing - Reader ready screen at block 5132 is displayed when the save is complete.
