Apparatus, system, and method for detecting the presence and controlling the operation of a mobile device within a vehicle

0001The present specification relates to devices, systems, and methods for detecting the presence of mobile devices inside a vehicle and controlling their operation.

0002Wireless devices, including mobile devices such as mobile phones, smartphones, laptops, laptops and tablets (eg Apple's iPad®) are well established in modern society. However, it is dangerous to use mobile devices while driving a vehicle. This problem is serious for inexperienced vehicle drivers, such as young people who have just learned how to drive. The rate of vehicle accidents involving mobile devices is increasing, especially for teenagers. Sending text messages while driving a moving vehicle is dangerous and can lead to accidents. More generally, operating the keyboard while driving a vehicle is dangerous.

0003As described above, there is a concern that the driver's attention will be distracted due to the widespread use of mobile devices and the general use of mobile devices while driving. When a driver speaks or text-messages on his cell phone, he or she may be distracted from driving and lose control of the vehicle he or she is driving. Therefore, it is not uncommon to see someone involved in an accident who is speaking or texting on a mobile device without paying attention to the road. Recent studies have shown that people who drive a vehicle and talk on their cell phones have as many drawbacks as those who drive drunk. Not only is the driver's attention distracted, but the driver also looks aside to make a call or see who the call came from.

0007This specification describes devices, systems and methods that detect the presence of a mobile device, such as a wireless device, and control or disable its operation when it is detected. In particular, the present specification detects the presence of a mobile device, eg, a wireless device, in place inside a vehicle, and if it is detected in place, part or all of the functionality of that mobile device. It is about an embodiment of a device, system and method of disabling. More specifically, this specification is about automatically preventing a person in the driver's seat of a vehicle from using a mobile device to perform text messages or other similar very dangerous actions. is there.

0008It should be understood that the specification is not limited to the particular embodiments or embodiments described, and that they can be modified. Also, the terms used herein are intended only to describe a particular aspect or embodiment, and are not intended to be limiting, to detect the presence of a mobile device inside a vehicle. The technical scope of the devices, systems and methods that control the operation of the mobile device when it is detected is defined only by the appended claims.

0009In one embodiment, the present specification provides devices, systems and methods for detecting mobile devices inside a vehicle and limiting its use, whether the vehicle is moving or stationary. Mobile devices, such as wireless devices, include, for example, mobile phones, smartphones, laptops, laptops, tablets (eg Apple iPads), netbooks, and other wireless mobile devices that users may be involved in in the car. It may be, but it is not limited to these. In one embodiment, at least one sensor located inside the vehicle detects the presence of the mobile device in the driver's side area of the vehicle. When the presence of a mobile device is detected, the behavior of the mobile device is controlled, disabled, or changed for a person located in the driver's side area, but for other persons located in other areas of the vehicle. , Mobile device behavior is not controlled, disabled, or changed.

0010FIG. 1 shows a vehicle 100 with a cabin 104 for accommodating a person in the driver's seat 106. It should be noted that in the present specification, the term "vehicle" is used in a broad sense, and it will be understood that it has a meaning including all kinds of transportation equipment. For example, Vehicle 100 is any type of vehicle, truck, SUV, aircraft, ship, spacecraft, or other means of transportation, or a combination thereof, that should detect and control communication by a driver using a mobile device. You may.

0011The mobile device detection and control system 102 is located on the dashboard 108 of the vehicle 100 or inside the dashboard 108. In one embodiment, the mobile device detection and control system 102 detects the presence of a mobile device located on the driver's seat 106 side of the vehicle 100 and interferes with the communication of the mobile device, or a specific function or feature of the mobile device. Interfere with or redirect the operation of the mobile device to a hands-free alternative system. In other embodiments, at least some elements or components of the mobile device detection and control system 102 may be located in other areas of the vehicle 100.

0012It would be desirable to place the detection and jamming elements of the mobile device detection and control system 102 as close to the driver as possible. For example, the sensor and directional antenna of the mobile device detection and control system 102 may be located in the vicinity of the driver's seat 106. According to this configuration, the presence of the mobile device on the driver's seat 106 side of the vehicle 100 is detected more accurately, and interference with other mobile devices or other persons located inside the vehicle 100 is prevented, thereby driving. It is possible to allow a person in the passenger seat to use a mobile device while prohibiting the person from using the mobile device. Other elements or components, such as control logic, may be located elsewhere in the vehicle 100 away from the driver's seat 106.

0013In one embodiment, the mobile device detection control system 102 is configured to detect a signal transmission from a mobile device located within or near the detection area. According to the above-described embodiment, the detection region is substantially defined as a region on or near the driver's seat 106 side of the vehicle 100. However, in other embodiments, the detection region may be any predetermined region within the vehicle 100 without limitation. In one embodiment, the detector of the mobile device detection and control system 102 may be tuned to detect signal transmission in the frequency band used by conventional mobile phones operating on common cellular channels. When the signal is detected, the mobile device detection and control system 102 wirelessly controls the operation of the mobile device in one or more ways. For example, in one embodiment, the mobile device detection and control system 102 transmits a control signal to invalidate the operation of the mobile device via an interfering signal that interferes with the communication mechanism of the mobile device. While the jamming signal is being transmitted, the mobile device or other communication device within the detection area is disabled or only operational with limited capabilities. By transmitting noise or other signals on one or more channels used by the mobile device, the jamming signal forces it to interfere with the communication mechanism of the mobile device. In other embodiments, the jamming signal may be interpreted by the mobile device to disable one or more functions of the mobile device. In such an embodiment, the jamming signal may be communicated to the mobile device via a secondary channel, such as a Bluetooth® wireless connection, or another connection secondary to the primary cellular communication channel. Good. In some embodiments, the jamming module may communicate only on the primary communication channel of the mobile device, or in addition on one or more secondary channels.

0014Therefore, the mobile device detection and control system 102 may completely block the ability of the mobile device to make and receive calls, or may interfere sufficiently with the signal of the mobile device to make the use of the mobile device undesirable. Good. For example, if the jamming signal interferes with most of the conversation, the user will either postpone the conversation or stop the vehicle to continue the conversation uninterrupted. In another embodiment, the mobile device detection and control system 102 may disable the operation of certain components or functions of the mobile device. For example, the keyboard portion of the mobile device may be obstructed to prevent the user from using the text message function of the mobile device. In another embodiment, the mobile device detection and control system 102 may redirect the operation of the mobile device to a hands-free operation. These and other embodiments are described in more detail below.

0015In one embodiment, the mobile device detection control system 102 starts the detection process by transmitting a probe signal for detecting the presence of the mobile device in the detection area. When the probe signal is transmitted, the detection control system 102 waits for the echo signal reflected by the mobile device or the response signal transmitted by the mobile device. When the detection control system 102 detects an echo signal or transmission by the mobile device, the detection control system 102 transmits a control signal for controlling the operation of the mobile device. For example, in one embodiment, the detection and control system 102 transmits a control signal to disable the operation of the mobile device via a jamming signal that interferes with the communication mechanism of the mobile device. In another embodiment, the detection and control system 102 changes the communication path to a hands-free system, such as a Bluetooth communication system.

0016FIG. 2 shows an embodiment of the mobile device detection control system 102. In one embodiment, the mobile device detection and control system 102 is configured to detect the presence of a mobile device 200 located within or near the area of the driver's seat 106 of the vehicle 100. When the mobile device 200 is detected, the mobile device detection control system 102 is configured to control the operation of the mobile device 200. In one embodiment, the mobile device detection and control system 102 comprises a detection module 202 and a control module 204 coupled to the detection module 202. The detection module 202 includes a multi-band antenna 208 that receives a signal transmission from the mobile device 200, and the control module 204 includes an antenna 210 that transmits a control signal to the mobile device 200. In various embodiments, the detection module 202 and the control module 204 may share an antenna if these components are located in close proximity to each other.

0017In various embodiments, the mobile device 200 may be embodied as a handheld mobile device, computer, mobile phone, smartphone, tablet personal computer (PC), laptop personal computer, or a combination thereof. Examples of smartphones include Palm products, such as Palm's Treo® smartphones (currently Hewlett-Packard and HP), Blackberry® smartphones, and Apple's iPhone®. Includes Motorola's Droid® and others. Tablet devices include the iPad by Apple and the more common lightweight class of mobile computers known as netbooks. In some embodiments, the mobile device 200 comprises any type of wireless device, mobile station, or portable computer device, such as a laptop computer, ultra laptop computer, communication function, with an independent power source (eg battery). Mobile information terminal (PDA), mobile phone, PDA integrated with mobile phone, mobile unit, subscriber station, user terminal, portable computer, handheld computer, palmtop computer, wearable computer, media player, pager, It may be provided with, or implemented by, a message device, a data communication device, and the like.

0018In one embodiment, the detection module 202 is configured to detect the presence of a mobile device 200 located within a detection area 220 defined as a three-dimensional area within or near the driver's seat 106. The method of detecting the presence of the mobile device 200 may be modified based on the communication standard of the wireless technology used by the mobile device 200. Examples of wireless technology communication standards that can be used in the United States include code division multiple access (CDMA) systems, pan-European digital mobile communication systems (GSM®) systems, and North American digital cellular (NADC) systems. , Time Division Multiple Access (TDMA) Systems, Extended TDMA (E-TDMA) Systems, Narrowband High Performance Mobile Phone Services (NAMPS) Systems, 3G Systems, For example Wideband CDMA (WCDMA®), 4G Systems, CDMA- 2000, Universal Mobile Communication System (UMTS) system, Digital Integrated Extension Network (iDEN) (improved method of TDMA / GSM), etc. may be included. These wireless communication standards are well known to those skilled in the art. The frequency and signal strength of the radio frequency (RF) signal transmitted by the mobile device 200 depends on the type of network and communication standard. Generally speaking, the detection module 202 detects an RF signal or electromagnetic energy emission transmitted by the mobile device 200. Thus, in one embodiment, the detection module 202 can also be configured to lock to a particular cellular frequency or cellular frequency band, or scan all available cellular or cellular frequency bands for mobile. It can also be configured to lock on the RF signal transmitted by device 200.

0019In one embodiment, the detection module 202 may include a sensor module 216 coupled to the multiband antenna 208. The sensor module 216 may be tuned to detect energy at a predetermined signal strength in an electromagnetic signal 206, such as an RF signal, transmitted by the mobile device 200 and received by the antenna 208. By the electromagnetic signal 206 transmitted by the mobile device 200 when the mobile device 200 makes a call or communicates with a cellular base station (eg, searching for a base station signal or contacting a base station or cell). It will be appreciated that the signal strength or power of the radiated energy is maximized. When the mobile device 200 is turned off or not communicating with a cellular base station, little energy is radiated in the electromagnetic signal 206. In the latter case, that is, when the mobile device 200 is powered on but not communicating with the cellular base station, the mobile device 200 will probably only detect if the detection module 202 has extremely sensitive components. Will be done. Many common mobile devices 200 radiate energy at power levels ranging from about 0.5 mW to about several hundred mW. The detection module 202 with appropriate sensitivity can be configured to detect electromagnetic signals 206 at power levels in this range. Many wireless electronic devices are capable of detecting low level power in the electromagnetic signal 206. This is because airlines are very sensitive to the behavior of electronics at key points in the flight, some electronics should be turned off near sites where there is a risk of explosion, and some. One reason is that mobile phones should be turned off around the types of medical equipment.

0020Mobile devices 200, such as mobile phones using the GSM standard, are known to generate detectable radio interference. GSM mobile phone users can use the mobile phone near electronic devices (eg, radio receivers, stereo systems, TV sets, wired / landlines, or other GSM mobile phones) from the GSM mobile phone. It is well known that a radio transmission can be "picked up" by the electronic device and a signal proportional to the envelope of the wireless transmission can be generated inside the electronic device. In fact, this normally undesired signal can even interfere with the operation of electronic devices. For example, it is particularly well known that GSM mobile phones pose a potential risk for cardiac pacemaker wearers. This is because if the GSM mobile phone is very close to the wearer's chest, the GSM signal can interfere with proper pacemaker operation.

0021In one embodiment, the sensor module 216 may be configured to take advantage of the detectable radio interference of the electromagnetic signal 206 generated by the mobile device 200 when the mobile device 200 is communicating with the cellular base station. it can. When the sensor module 216 of the detection module 202 detects the electromagnetic signal 206, the sensor module 216 estimates the presence of the mobile device 200 located in or near the detection area 220, that is, the driver's seat 106, and the control module 204 Communicate signal 212 to. The jamming module 218 is arranged so as to be able to communicate with the control module 204. In one embodiment, when the control module 204 receives the signal 212 from the detection module, the jamming module 218 transmits the jamming signal 214, which can only be detected by the mobile device 200 located in the detection area 220, via the antenna 210. To do. In various embodiments, the electromagnetic interference signal 214 may be a signal that disables the operation of the mobile device 200, may disable certain functions of the mobile device 200, or may disable the operation of the mobile device 200. You may redirect to hands-free operation. The control module 204 may be arranged communicably with the system of the vehicle 100, such as the ignition system 224, the gearbox 226, or various sensors 228. The logic of the control module 204 monitors the function of the system of the vehicle 100 in addition to detecting the presence of the mobile device 200. Therefore, the jamming module 218 may be activated only when the monitored function of vehicle 100 is activated. For example, if the sensor module 216 detects the presence of the mobile device 200 in the detection area 220, the jamming module 218 will use the jamming module 218 when the vehicle 100 is activated, when the vehicle 100 moves out of the parking lot, or when it is in gear. , Or one or more sensors may only be activated when the motion of the vehicle 100 is detected.

0022In one embodiment, the sensor module 216 may include an energy recovery device that recovers the energy in the electromagnetic signal 206 transmitted by the mobile device 200. The energy recovery device receives the radiated energy at the antenna 208 and converts the energy into a voltage for driving the detection module 202 and communicating the signal 212 to the control module 204. In another embodiment, the energy recovery device may be provided separately from the sensor module 216, or the sensor module 216 may be driven by the voltage generated by the energy recovery device. In any embodiment, the voltage generated by the energy recovery device may be used to determine the presence of the mobile device 200 in the detection area 220. Therefore, the sensitivity of the sensor module 216 is such that the energy recovery device responds only to radiant energy levels that would normally occur if the mobile device 200 is located inside the detection area 220, and is located outside the detection area 220. It is adjusted so that it does not react to the electromagnetic energy transmitted by the device 222. In this case, the non-driver occupant is free to use his or her mobile device 222 located outside the detection area 220 without triggering the detection module 202.

0023In other embodiments, the detection module 202 is coupled to the electrical system of vehicle 100 and may be powered by the vehicle's battery or from another battery. In such an embodiment, the detection module 202 comprises a frequency scan / power level measurement module that measures the power of the electromagnetic signal 206 transmitted by the mobile device 200. Therefore, the sensitivity of the detection module 202 triggers the detection signal 212 when the detection module 202 detects the transmission power level corresponding to the mobile device 200 located in the detection area 220 and is located outside the detection area 220. It may be tuned so that it does not trigger the detection signal 212 for the transmit power level corresponding to the mobile device 222. This has maximum sensitivity to the transmission power level radiated by the mobile device 200 located inside the detection area 220 and to the transmission power level of the mobile device 222 located outside the detection area 220. This is achieved by devising the arrangement of the directional multi-band antenna 208 so that it has the minimum sensitivity.

0024In one embodiment, the control module 204 may include a jamming module 218 coupled to the antenna 210. The jamming module 218 is arranged to communicate with the antenna 210. The antenna 210 transmits a jamming signal 214 that interferes with the signal of the mobile device 200 and interferes with or interferes with the ability to make and receive calls using the mobile device 200. The jamming module 218 and the antenna 210 may be powered by the electrical system of vehicle 100 or by another battery. The jamming module 218 may be any device that interferes with the mobile device 200 or renders the mobile device 200 inoperable, transmitting a jamming signal 214. In some embodiments, the jamming module 218 may transmit a special signal selected to interfere with noise or one or more communication frequencies of the mobile device 200. For example, the jamming module 218 may transmit noise and interference signals that repeat on the control channel frequency of the mobile phone system. In some embodiments, the jamming module 218 may transmit on a narrow frequency band, or in other embodiments, a very wide frequency band may be selected. The exact method of interfering with the mobile device 200 by the jamming module 218 depends on the transmit and receive characteristics of the mobile device 200. One of ordinary skill in the art would be able to use any suitable jamming module 218 for any particular mobile device 200 considered.

0025According to one aspect, the jamming module 218 may be mounted on the vehicle 100. When the jamming module 218 is activated, it interferes with the ability of mobile phones to make and receive calls using the mobile device 200 located within the detection area 220. Depending on the wattage of the jamming module 218 (or the use of a directional antenna), the area where the mobile device 200 is jammed may be controlled. Thus, for example, the jamming module 218 interferes with the space 1-3 feet from the location of the jammer 218, or the ability of the driver to make and receive calls and send text messages, and occupants other than the driver. The mobile device 200 may be set to effectively interfere with incoming and outgoing calls in a space that does not interfere with the ability of the mobile phone to make and receive calls and send text messages.

0026In one embodiment, the antenna 210 can be placed under the dashboard of the vehicle 100 or on the windshield on the driver's side. Alternatively, a directional antenna can be placed inside the driver's seat to interfere with the driver making a call or sending a text message.

0027In one embodiment, the control module 204 is driven by the driver of the vehicle 100 when the mobile device 200 is detected inside the detection area 220 in combination with an ignition switch, transmission switch, or other vehicle sensor mechanism. It can also be used to interfere with communication. In one embodiment, the ignition switch may be monitored to cause the jamming module 218 to transmit only if the mobile device 200 is detected on the driver's seat 106 side of the vehicle 100 and the ignition switch is turned on. .. As a result, the driver of the vehicle 100 needs to stop the vehicle 100 in order to communicate with the outside. Interference module 218 will interfere with further communication until the vehicle 100 is switched off. In another embodiment, the jamming module 218 only occurs when the mobile device 200 is detected inside the detection area 220 and the automatic transmission of the vehicle 100 is moved from "parking" to a position where the vehicle 100 can move. It may be activated. When such a system operates normally, the driver of the vehicle 100 needs to stop the vehicle 100 and move the transmission to "parking" or turn off the engine in order to operate the mobile device 200.

0028In one embodiment, the jamming module 218 may be configured to operate inside the vehicle 100. In some cases, the antenna 210 coupled to the jamming module 218 of the control module 204 is provided with a jamming signal 214 so that occupants other than the driver of the vehicle 100 can continue to operate the other mobile device 222. It may be configured to have a given power level and directional attributes that act only on the detection area 220. In such a case, the jamming signal 214 may be generally limited to the detection area 220 of the vehicle 100. In some embodiments, the jamming signal 214 is localized to another region of the vehicle 100, disabling the operation of the mobile device inside that region, and allowing other mobile devices outside that region to operate. It can also be.

0029In various embodiments, the power levels of the antenna 210 and the jamming signal 214 can be configured to deliver the jamming signal to the detection area 220 very accurately. In one embodiment, using a directional antenna located inside the vehicle 100, where the largest jamming signal is delivered to the detection area 220 and the smallest jamming signal is delivered outside the detection zone 220, the above. May be implemented. In such an embodiment, the detection module 202 indiscriminately detects any transmission from all mobile devices 200, 222 inside the vehicle 100, and the jamming module 218 transmits the jamming signal to the detection area 220. It may be configured to interfere with the mobile device 200 inside the detection area 220 without affecting the mobile device 222 outside the detection area 220. In such an embodiment, it is not necessary to determine whether the mobile device is inside the detection area 220, so that the design of the detection module 202 can be simplified.

0030In one embodiment, the jamming module 218 may allow incoming calls on the mobile device 200 while prohibiting outgoing calls from the mobile device 200. When the detection module 202 detects the energy of the electromagnetic signal 206 from the outgoing call attempted by the mobile device 200, the signal 212 activates the jamming signal 214. In such an embodiment, the detection module 202 comprises an additional module that identifies the ID of the mobile device 200, whereby the jamming signal 214 after the control module 204 has authenticated the ID of the mobile device 200. May be transmittable.

0031In other embodiments, the sensor module 216 may be used to detect and allow or disallow any kind of operation of the mobile device 200. For example, the mobile device 200 may receive a call but interfere with the outgoing call. In another embodiment, some calls, such as emergency calls, may be allowed to originate and other calls may be blocked. Any other detectable feature of the mobile device 200 can also be selectively allowed or disabled by the jamming module 218.

0032In one embodiment, the mobile device 200 receives the jamming signal 214 and operates in degraded mode. For example, the mobile device 200 may be prohibited from making calls except for emergency calls to the 911. In another embodiment, the mobile device 200 may be allowed to receive all calls or calls from callers in a given list, while making calls is prohibited. Various degraded modes may be used, and in some embodiments, details of the operation allowed by the configuration may be defined.

0033In one embodiment, the control module 204 initiates the detection process by transmitting a probe signal to detect the presence of the mobile device 200 inside the detection area 220. When the probe signal is transmitted, the detection module 202 waits for an echo signal reflected by the mobile device 200 or a response signal transmitted by the mobile device 200. When the detection module 202 detects an echo signal or transmission by the mobile device 200, the control module 204 transmits a control signal for controlling the operation of the mobile device 200. For example, in one embodiment, the jamming module 218 transmits a control signal to nullify the operation of the mobile device 200 by a jamming signal 214 that interferes with the communication mechanism of the mobile device 200. In another embodiment, the control module 204 may change the communication path to a hands-free system, such as a Bluetooth communication system.

0034FIG. 3 shows an embodiment of a power sensor circuit 300 that detects radiant energy from an electromagnetic signal 206 transmitted by a mobile device 200. The illustrated power sensor circuit 300 is an embodiment of the sensor module 216 described in connection with FIG. The power sensor circuit 300 also converts the energy of the electromagnetic signal 206 into a voltage indicating the position of the mobile device 200. In the illustrated embodiment, the power sensor circuit 300 is not connected to the power source of the vehicle 100 or another battery. Rather, the power sensor circuit 300 is an implementation example of an energy recovery circuit that extracts its own power from the radiant energy from the electromagnetic signal 206 transmitted by the mobile device 200. The electromagnetic signal 206 detected by the antenna 208 is filtered by the tuning circuit 306 to fit into the most common frequency band used by mobile devices. In one embodiment, the tuning circuit 306 may include an inductor L and a capacitor C selected to tune the power sensor circuit 300 to a desired frequency band. Those skilled in the art will appreciate that tuning circuits can be implemented using digital or analog tuning techniques and are therefore not limited to the embodiments disclosed in FIG.

0035Diode D_rfIs a high frequency diode that operates to partially rectify the electromagnetic signal 206 received by the antenna 208 and tuned by the LC circuit. The output of the high frequency diode is the capacitor C_oThe predetermined voltage V_dTo charge. Therefore, the power sensor circuit 300 transmits the radiated electromagnetic signal 206 to the voltage V corresponding to the position of the mobile device 200 inside the vehicle 100._dConvert to. Here, referring to FIGS. 2 and 3, the output capacitor C_oVoltage V across_dIf is above a predetermined level, it indicates the presence of the mobile device 200 inside the detection area 220. Voltage V_dIs compared with the threshold voltage Vt by the comparator 306. The threshold voltage Vt is predetermined as a voltage level corresponding to the mobile device 200 located in the detection area 220. The output of the comparator 306 is provided to the detection logic module 304. The detection logic module 304 may be a part of the detection module 202. The detection logic module 304 generates the detection signal 212 and communicates the detection signal 212 with the control module 204. Upon receiving the detection signal 212, the control module 204 activates the jamming module 218 to interfere with the operation of the mobile device 200. As mentioned above, in certain embodiments, the jamming module 218 may be activated only if other logical conditions, such as conditions for the state of the ignition system, gearbox or other sensor, are met.

0036Further referring to FIGS. 2 and 3, it is desirable to determine when to turn off jamming module 218. Therefore, in one embodiment, once V_dWhen the signal is provided to the control module 204, the detection logic module 304 activates the switch 302 and outputs the capacitor C._oDischarge from. At about the same time, the interfering circuit 218 is turned off. If the mobile device 200 is still active in the detection area 220, the electromagnetic signal 208 is picked up by the antenna 208 and the capacitor C_oFill the voltage V to activate the jamming module 218_dWill generate. In this cycle, the mobile device 200 is removed from the detection area 220 and the emitted electromagnetic signal 208 is too weak to activate the power sensor circuit 300, or the mobile device 200 is deactivated or turned off. It will be repeated until there is little or no electromagnetic signal 208 radiated.

0037In the embodiment shown in FIG. 3, the tuning circuit 306 may be implemented to have a bandwidth that includes the most commonly used mobile phone frequencies. Since the tuning circuit 306 is fixed, it is tuned to a wide frequency band so as to receive the electromagnetic signal 208 from about 0.8 GHz to about 2 GHz, as shown in Table 1 below. However, in other embodiments, the tuning circuit 306 ensures that the power sensor circuit 300 is more accurately tuned to the appropriate frequency band of the mobile device 200 located in the detection area 220, as described in connection with FIG. A frequency band scanner may be included that scans the detection area 220 by switching between multiple tuning elements for multiple frequencies.

0038FIG. 4 shows an embodiment of a power sensor circuit 400 including a tuning circuit 406 with a scanner 402 arranged in series with the antenna 208.

0041The multi-band detector 500 detects the radiant energy in the signal 506 received by the unidirectional multi-band antenna 508 to detect the presence of the mobile device 200 in the detection area 220, and the low level by the detection module 502. It can be mounted using a variety of components that perform RF power measurements in. RF power levels may be measured directly or sampled. Recently, multiple integrated RF power detectors have become available, intended for wireless networks and mobile phones. Since these integrated circuits are mass-produced using integrated circuit technology, they are reliable, inexpensive, and often have typical microwave diodes such as the high frequencies shown in FIGS. 3 and 4. Cheaper than diodes. Many of them are designed to operate in the GHz range, cover some amateur radio microwave bands, and some operate above 10 GHz.

0042In one embodiment, the RF power detection module 502 can be implemented using Linear Technology's LTC5508 integrated circuit capable of up to 7 GHz. It works well within the band required for the mobile device frequency bands shown in Table 1. This integrated circuit operates at 3-5V and a few mA and can be connected to a vehicle power source or another battery. The LT5534 log-amplifier detector, capable of up to 3GHz and having a dynamic range of 60dB, can be used to amplify the RF power signal detected by the LTC5508 integrated circuit.

0043The multi-band detector 500 can be used to measure the RF power transmitted by the mobile device 200, or it can be used to measure the antenna emission pattern. The sensitivity of the multi-band detector 500 will be useful in low-level power measurements as an "RF detector" that detects RF leaks from the mobile device 200. Since the multi-band detector 500 provides a fast response, it can be used to detect modulation and noise level from the multi-band antenna 506.

0044FIG. 6 is a diagram showing an inner portion of the vehicle 100 comprising one embodiment of the mobile device detection and control system 102 located inside the dashboard 108 of the vehicle 100. Figure 6 shows three potential locations inside dashboard 108 where the mobile device detection and control system 102 can be deployed. It will be appreciated that the detection and control system 102 can be located on or within dashboard 108, one or more of these locations. It would be preferable to place the detection control system 102 inside the dashboard 108 to prevent unauthorized modification by the user. Therefore, the detection control system 102 shown is virtual to indicate the detection control system 102 located inside the dashboard 108. In another embodiment, the control module 203 records the situation in which the detection control system 102 is disabled by the owner of the vehicle 100 with or without the help of an auto mechanic. It can be configured to carry out a collection process. Such tampering recording and detection capabilities will help in post-accident investigations in deciding whether detection control system 102 will be disabled and thereby exempt from insurance coverage. Let's go.

0045With reference to FIGS. 1 to 6, the mobile device detection control system 102 includes a detection module 202 and a control module 204 coupled to the detection module 202. The detection module 202 detects the presence of the mobile device 200 inside the detection area 220 (discovery umbrella). When the detection module 202 detects the presence of the mobile device 200 inside the detection area 220, the control module 204 activates the jamming module 218 that transmits the control signal 214. The control signal 214 interferes with the operation of the mobile device 200 located inside the detection area 220 without interfering with the mobile device 222 located outside the detection area 220.

0046In one embodiment, the mobile device detection and control system 102 may trigger when the driver gets into the vehicle 100. When triggered, the mobile device detection and control system 102 is activated to enter detection mode and establish no communication system (NoCom system). The detection mode is that the mobile device detection and control system 102 uses one or more sensors and logic to signal 206 electromagnetic signals from the mobile device 200, such as RF, WiFi®, cellular, and satellite communications signals. It is the process of detecting the existence. In one embodiment, the detection process is initiated by the mobile device detection and control system 102. The start of this detection process does not depend on the operation from the driver. Separation of the above process from drivers (young and old) is advantageous as it eliminates trust in self-defense, which is not working well under currently valid legislation. Thus, the trigger condition may be the activation of a switch, eg, the ignition switch 602 of the vehicle 100, or the deactivation of the "parking" sensor 604 of the automatic transmission of the vehicle 100.

0047Therefore, when the vehicle 100 is ignited, the mobile device detection and control system 102 will initiate the detection process via logic that controls the operation of the detection module 202 and the control module 204. According to the detection process, the logic instructs the sensor module 216 to start sensing and scanning any kind of communication signal 206 transmitted from the mobile device 200 inside the detection area 220 inside the driver's seat 106 of the vehicle 100. Will. In one embodiment, the sensor module 216 can be located inside the console of dashboard 108 or inside the microphone of a hands-free set. According to this configuration, hiding the sensor module 216 can prevent the driver from tampering with the mobile device detection and control system 102 by shielding the sensor module 216 or preventing the detection process from being activated. .. In one embodiment, the sensor module 216 may be coupled to the ignition 602 to render the vehicle 100 inoperable if the sensor module 216 is shielded.

0048The above logic provides a detection process that detects the communication signal 206 transmitted by the mobile device 200 located inside the detection area 220 to prevent the driver from using the mobile device 200 normally. The detection process will detect and control the driver's side mobile device 200. However, the above logic does not prevent occupants other than the driver from using the mobile device 222 outside the detection area 220.

0049When the detection process is initiated, in one embodiment, if the mobile device 200 is a smartphone, the mobile device detection and control system 102 can automatically connect to the hands-free communication system of the vehicle 100. If a hands-free communication system is not available, the mobile device 200 will be disabled by the control signal 214 transmitted by the jamming module 218. Even in this case, the mobile device detection and control system 102 will always allow 911 emergency calls.

0050Also, when the detection process is initiated, if the mobile device 200 is a smartphone and is detected inside the detection area 220, in one embodiment the mobile device detection control system 102 will be a text message of the mobile device 200. It may be configured to disable the send / receive function. In one embodiment, all received text messages are stored, as they are today. In one embodiment, the mobile device detection and control system 102 reads the text aloud via a Bluetooth / hands-free communication system and replies with the text input voiced via the Bluetooth / hands-free communication system via logic. It may be configured. In such an embodiment, the jamming module 216 may communicate with the mobile device 200 via a secondary channel, such as a Bluetooth wireless connection or any other secondary secondary connection to the primary cellular communication channel. .. In some embodiments, the jamming module 216 may communicate on the primary communication channel of the mobile device 200, or in addition, on one or more secondary cellular communication channels.

0051Further, when the detection process is initiated, if the mobile device 200 is a smartphone and is detected inside the detection area 220, in one embodiment, the mobile device detection control system 102 disables the email sending and receiving function. It may be configured to be. In one embodiment, all received emails are stored, as they are today. The mobile device detection and control system 102 is configured via a logic module to read e-mails via a Bluetooth / hands-free communication system and reply by voice-input e-mails via a Bluetooth / hands-free communication system. You may be.

0052Further, when the detection process is initiated, if the mobile device 200 is an iPad or netbook device and is detected inside the detection area 220, in one embodiment, the mobile device detection control system 102 will send a text message / It may be configured to disable the e-mail sending and receiving function. As it is, all received emails are saved. The mobile device detection and control system 102 has a logic module that reads out the email / text via the Bluetooth / hands-free communication system and returns the voice-input email / text via the Bluetooth / hands-free communication system. It may be configured via.
