POftTATlty WIRELESS REMOTE CONTROL DEVICE

FOR USE WITH A DRIVING VEHICLE PC MATERIAbtrS *

TECHNICAL FIELD

The present invention relates generally to material handling vehicles, and more particularly, to complementary portable wireless remote control devices for use with material handling vehicles for better operation thereof.

BACKGROUND OF THE INVENTION

Forklifts are commonly used to pick up low-level orders for the purpose of picking up supplies in warehouses and distribution centers. These order picking trucks typically include load hauling forks, a power unit, and a platform on which an operator can stand and drive while controlling the truck. The power unit has a steering wheel and corresponding steering control and traction mechanisms, for example a movable steering arm that engages the steering wheel. A control handle attached to the steering arm typically includes the operational controls necessary to operate the forklift, such as the controls for raising and lowering the forks and for controlling the speed and direction (forward or reverse) of the forklift.

In a typical supply pickup operation, an operator fills orders by selecting from supply items

The operator drives a forklift to pick up low-level orders to a first location where items from a first order are to be picked up. In a picking process, the operator retrieves the ordered supply items from their associated storage areas, and places the picked supplies on a pallet, picking cage, or other support structure carried by the forklift forks to pick up orders. The operator then advances the forklift to pick up orders to the next location where items are to be picked up. The above process is repeated until all the supply items from the orders have been collected.

The operator typically stands on the forklift platform to ride the forklift to pick up orders when the distance between consecutive picks is longer, for example, twenty feet or more (approximately 6.1 meters). In a corresponding manner, the operator walks alongside the forklift when the distance along the route between consecutive pickups is short. In accordance with the foregoing, some order picking trucks include rocker switches located on the truck in the vicinity of the forks and / or on or near the control handle. The rocker switches can be used by a walking operator l r.

However, for these actions, the operator is required to interrupt picking while the forklift is relocated to pick up orders at the next location. Accordingly, the operator may be required to move out of a desired working position or modify a desired walking route to reach the rocker switches.

It is not uncommon for an operator to be required to repeat the picking process several hundred times per order. Furthermore, the operator may be required to collect numerous orders per shift. As such, the operator may be required to spend a considerable amount of time relocating and repositioning the forklift to pick up orders, reducing the time available for the operator to pick up supplies.

Referring now to the drawings, and in particular to Figure 1, a material handling vehicle, which is illustrated as a low-level order picking forklift 10, generally includes a cargo handling assembly 12 that is extends from a power unit 14. The load handling assembly 12 includes a pair of forks 16, each fork 16 having a load bearing wheel assembly 18. The load handling assembly 12 may include other load handling features in addition to, or in lieu of, the illustrated configuration of the forks 16, such as a load backrest, scissor lift forks, spacers, and height adjustable forks. separated, a mast, a loading platform, a collection cage or other support structure carried by the forks 16 or otherwise provided for handling a load supported and carried by the forklift 10.

The illustrated power unit 14 comprises an operator area 30 having a first end section 32 positioned opposite the forks 16, a second end section 34 positioned adjacent to the forks 16, and an operator step station 36 that divides the first end section 32 of the second end section 34. A first work area is provided towards the first end section 32 of the power unit 14 and includes a control area 40 for driving the forklift 10 and for controlling the features of the ί assembly:

cargo handling institute 12. The first extension section / ^ f, may optionally comprise a first storage area 46, for example, to secure loose items that a corresponding forklift operator can keep track of. The first end section 32 also defines a compartment 48 for containing a battery, control electronics, and motors, such as a traction motor, a steering motor, and a lift motor for the forks (not shown).

As shown for purposes of illustration, and not by way of limitation, the control area 40 comprises a handle 52 for directing the forklift 10, which may include controls such as clips, butterfly switches, thumb wheels, rocker switches. , a hand wheel, a rudder, etc., to control acceleration / braking and the direction of travel of the forklift 10. For example, as shown, a control such as a switch clip 54 may be provided on the handle 52, which is spring biased to a central neutral position. Rotation of switch clip 54 forward and up will cause forklift 10 to move forward, eg, power unit 14 first, at a speed proportional to the amount of rotation of switch clip 54. In a similar manner, rotation of the switch clip 54 towards the rear and down of the forklift 10 will cause the forklift 10 to move in reverse, for example,

U «J» «'t-' ·« - y '' / í_z·, The forks 16 first, at a speed proportional to P ^ ifí ^ scÁntilfewJsL ^ '' of rotation of the switch holder 54. Tamhián ... &amp; «- may-B —-— provide devices for sounding a horn or to carry out other forklift functions.

The operator step station 36 provides a platform 56 upon which an operator can stand to drive the forklift 10 and operate the load handling features of the forklift 10.

Presence sensors 58 may also be provided, for example, on, above, or below the floor of platform 56, or may be otherwise provided around operator station 36, to detect the presence of an operator on the forklift. 10 as will be explained in more detail herein.

In the example forklift of Figure 1, the presence sensors 58 are shown in hatched lines, indicating that they are positioned under the platform 56. Under this configuration, the presence sensors 58 may comprise load sensors, switches, and the like. As an alternative, presence sensors 58 can be implemented above platform 56, such as through the use of ultrasonic, capacitive, or other suitable sensing technology.

The second end section 34 of the power unit 16 may comprise an operator rest cushion or other suitable support structure, a grab bar 62, and a second storage area 64. An antenna 66 is provided.

IT 'inst ii - o, Λ to receive the control signals from a corresponding remote device ^ wj ^ tf ^ coL ^ f ^ bi * /' 70, which, in one embodiment, comprises a transmitter, a battery, and a control structure, as will be described in greater detail herein. As shown, radio frequency (RF) operation is facilitated by coupling antenna 66 to second end section 34 of power unit 14, for example, along or otherwise near a pole that is vertically extends 67, which can also support a light source 68. Placing antenna 66 over light source 68 on pole 67 provides a convenient location to promote radio frequency (RF) reception, and can eliminate variability from light source 68 and its associated cables running through the line. antenna 66. Alternatively, antenna 66 can be positioned elsewhere on forklift 10. The light source 68 can be used to provide information about the status of the forklift 10 and / or the status of wireless communication between a wireless remote control and the appropriately paired forklift.

For example, the light may illuminate when the forklift 10 is in motion, and it may blink or illuminate in defined patterns to indicate prescribed conditions.

The grab bar 62 can be used by the operator as a holding surface, for example, when entering, exiting, or operating the forklift 10. Additionally, the grab bar 62 and other included posts can be used in addition, for example, A bar

For example, grab bar 62, or second end section 34 in general, can be used to mount supplemental operating controls.

The example forklift 10 is provided for illustration and not by way of limitation. In practice, the forklift 10 can be implemented in other formats, styles, and features, such as an end control pallet forklift that includes a tiller arm that engages a tiller handle to steer the forklift. In this regard, the forklift 10 may have similar or alternative control configurations to those shown in Figure 1.

In addition to, or instead of, light source 68, an indicator, eg, audible, visible etc., may be associated with the remote control device system, as will be described in greater detail herein. For example, as shown, the forklift 10 may include an indicator, such as a strobe light 72, which is illustrated positioned on or adjacent to the second end section 34 of the power unit 14 mounted tv-i15'k i ;

Strobe 72 can be set to a unique pattern that is associated with remote control operation. As such, when the forklift 10 is not operating under the wireless remote control, the strobe pattern may change in relation to when the forklift 10 is operating under the wireless remote control. For example, the strobe light 72 can be turned off or its intensity, pattern, etc. can be changed when the forklift 10 is not under the wireless remote control. Comparatively, the strobe can flash when the forklift 10 is under it. wireless remote control. Speed, intensity, or other patterns may vary based on forklift operating conditions, for example to indicate motion, fault conditions, etc. As illustrated, the light pattern 74 from the strobe 72 is directed generally downward at an angle toward the forks 16. As such, the strobe area is not distracting the operator or others in the vicinity of the forklift 10, for For example, in the work aisle of forklift 10, yet it is obvious and visible to the operator and others in the vicinity of forklift 10.

The forklift 10 may also comprise one or more '' 'Ά

from the power unit 14 and / or to the sides of the power unit 14. The object sensors 76 may comprise any suitable contact or proximity sensing technology, such as ultrasonic sensors, optical recognition devices, Infrared sensors, etc. For example, object sensors 76 can be implemented by Bosch URF6 ultrasonic sensors and a corresponding controller.

The object sensors 76 can be used to detect the presence of objects within a previously defined area of ​​the power unit 14, such as within a previously defined detection area 78, as illustrated in hatched lines. In practice, the range of each object sensor 76 may be different, and the sensing areas of sensor 78 may overlap or otherwise be arranged, depending on the specific implementation and selection of proximity sensing technology. For example, the object sensors 76 towards the front of the power unit 14 may have a range of approximately 0 to 5 feet (0 to 1.5 meters), and the object sensors 76 towards the sides of the power unit 14 they can range from about 0 to 2 feet (0 to 0.6 meters). Furthermore, the detection range of the object sensors 76 can be adjustable or can be made dynamically variable in another way. For example, the range of object sensors 76 can be extended if certain

<img file="MX354755B_D0009.tif" />

or rare '>>; · O' operating conditions, etc. As an example, eP^£of <lge ^> and object sensors 76 can be adjusted based on the speed of the forklift 10 when moving under the wireless remote control.

In addition, the forklift 10 may comprise one or more load presence sensors 80. The charge presence sensors 80 may comprise proximity or contact technology, for example, a contact switch, a pressure sensor, an ultrasonic sensor, an optical recognition device, an infrared sensor, or other suitable technology that detects the presence of a suitable load bearing structure, for example pallet or other platform, collection cage, etc. The load presence sensors 80 can be mounted towards the front of the power unit 14, on a load backrest or other suitable support structure, the location of which will likely depend on the technology deployed.

Referring to Figure 2, a block diagram 100 illustrates a control configuration for integrating remote control commands with forklift 10. Antenna 66 is coupled with a receiver 102 to receive commands issued by remote control device 70 . Receiver 102 passes received commands to controller 103, which implements appropriate actions in response to received commands, for example, by operating relays or other actuation devices controlled by electricity, magnetism, hydraulics, pneumatics, etc. , or by

In an exemplary configuration, remote control device 70 is operative to wirelessly transmit a tour request as a signal of a first type, also referred to herein as a tour signal or day signal, to the receiver. on the forklift 10. The travel request is used to request the forklift 10 to advance or move in a first direction. The first direction can be defined, for example, by the movement of the forklift 10 in a power unit 14 first, that is, the direction of the forks 16 rearward.

However, in an alternative way, other directions of travel can be defined. Furthermore, the forklift 10 can be controlled to travel in a generally straight direction or along a predetermined orientation.

The signal of the first type is received by receiver 102 and communicated to controller 103. If controller 103 determines that the course signal is a valid course signal and that the current vehicle conditions are appropriate (as explained in more detail later), the controller 103 sends a signal

As will be described in greater detail herein, stopping the forklift 10 can be implemented either by allowing the forklift 10 to slow down to a stop, or by applying of a brake to stop the forklift.

As an example, the controller 103 may be coupled in a communicable manner with a traction control system, illustrated as a controller for the traction motor 106 of the forklift 10. The controller responds to the reception of the signal of the first type by the receiver 102 in order to evaluate at least one condition of the vehicle, to decide whether to implement the drive request based on the evaluation of the condition of the vehicle (s) and to cause the traction control system to advance the vehicle if the controller decides to implement the ride request based on the evaluation of the condition (s).

Traction motor controller 106 is coupled with traction motor 107 that drives at least one steered wheel 108 of forklift 10. Controller 103 can communicate with traction motor controller 106 in such a way as to limit speed. of the forklift 10 in response to receiving a request for a ride from the remote control device 70. For example, the travel speed of the forklift 10 can be limited to the typical walking speed, for example, up to or about 2.75 miles per hour (4.4 kilometers per hour).

There may be noise and / or interference, for example remote and wireless control systems in the neighborhood '4e + forklift 10. As such, either the receiver 102 or the controller 103 can perform signal analysis to discriminate. valid travel signals from invalid signals. For example, controller 103 may determine that receiver 102 has provided a path signal at an inappropriate frequency or on an inappropriate channel. Furthermore, an operator and / or transmitter identification (ID) code may be embedded in the tour request as will be described in more detail below. In that case, the controller 103 can be operatively configured to respond to messages bearing only certain ID codes, or to exclude / disregard commands from certain ID codes.

Also, the travel signal can be detected at a power level that is too strong or too weak to be considered a valid signal. For example, if a signal is too strong, it may indicate that an operator is too close to the forklift 10 to start the automated tour. In a corresponding way, if a signal is too weak, that may indicate that an operator has exceeded a previously determined range from the forklift 10 for permitted remote control.

Still further, the controller 103 may require an acknowledgment signal or other two-way communication from the

Under these and similar circumstances, the controller 103 may choose to disregard a received tour request and take no action if two-way communication is not properly confirmed. Still further, two-way communication can be used to pair receiver 102 on forklift 10 with a corresponding instance of a wireless remote control device 70 as will be described in greater detail herein.

Controller 103 may also refuse to recognize the course signal depending on vehicle conditions that are related to environmental or operational factors. For example, controller 103 may disregard an otherwise valid request for travel based on information derived from one or more of sensors 58, 76, 80. In this regard, sensors 58, 76, 80, etc., can be coupled to controller 103 via inputs 104 or via a suitable forklift network, such as a control area network bus (CAN ) 110. Also / alternatively, controller 103 may implement any other number of reasonable conditions to interpret and take action in response to received signals.

INSTITUTO MEXICANO Dfc THE PROPERTY controller 103 of the forklift 10 communicates with any forklift system or module connected with the can 1 tu bus to make decisions on how to implement the commands received from the remote control device 70. Furthermore, the relevant information derived from the forklift 10 can be communicated back to the remote control device 70 by using the transmitter 109 of the forklift 10 to communicate with a corresponding receiver in the remote control device 70.

The CAN protocol is a convenient network platform for material handling vehicles because there is no subscriber or station address in the conventional network sense. Rather, CAN defines a prioritized system of transmitted messages wherein the priority of a given message transmission over CAN bus 110 depends on a corresponding message identifier code. All nodes or modules connected to the CAN bus 110 can receive a message transmission from a first module. Accordingly, controller 103 can make intelligent decisions regarding wireless remote control and / or information exchange with a corresponding paired wireless remote control device 70, based on any number of factors, states, conditions, etc., that are can transmit through the CAN 110 bus.

The network may alternatively comprise any other bus system, for example a Local Interconnection Network (LIN) or a Vehicle Area Network (VAN), etc., or capabilities of

After recognition of a valid ride request, controller 103 interacts with traction motor controller 106, for example, via CAN bus 110 or other communication link, to advance the forklift.

10. Depending on the particular implementation, controller 103 may interact with traction motor controller 106 to advance forklift 10 a predetermined distance. Alternatively, controller 103 may interact with traction motor controller 106 to advance forklift 10 for a period of time in response to detection and sustained actuation of control on remote control device 70. In addition, the forklift 10 can be configured to travel for as long as a travel control signal is received. However, the controller 103 can be further configured to time out and stop the forklift 10 travel based on a predetermined event, such as exceeding a predetermined travel distance or time period regardless of whether the drive was maintained. a corresponding control on the remote control device 70.

Controller 103 may also communicate, for example, via CAN bus 110 or otherwise, with a steering control system to cause forklift 10 to adjust a travel path of forklift 10. For example, controller 103 may communicating with a steering controller 112 to command or otherwise control a steering motor 114 or other suitable control device, which also engages the steered wheels 108 of forklift 10. For example, controller 103 may straighten forklift 10, or adjust a steering angle of forklift 10 before or during a tour operation initiated by the wireless remote control. As such, the controller 103 can be defaulted to a mode of operation where the forklift 10 travels in a straight direction or along a predetermined orientation when the forklift 10 is moving under the wireless remote control in response to reception. of a tour request. Controller 103 may further impose a steering angle limit during remote control operations if forklift 10 is to travel in a direction where steered wheels 108 are not straight. For example, controller 103 may limit the angle that forklift 10 can travel when

IKÜ'JJIaíAL a range of about 5 to 10 degrees. Accordingly, in addition to moving the traction motor 107, the controller 103 may also straighten or adjust or otherwise control the steered wheel 108.

Remote control device 70 may also be operative to transmit a signal of a second type, such as a stop signal, designating that forklift 10 should brake and / or otherwise come to a stop. The signal of the second type may also be involved, for example, after implementing a tour command. The signal of the second type is received by receiver 102 and communicated to controller 103. If controller 103 determines that the stop signal is a valid stop signal, controller 103 sends a signal to a brake control system, for example, via CAN bus 110 or otherwise. For example, controller 103 may communicate with a brake controller 116 of forklift 10 to cause an appropriate brake setting 117 to bring forklift 10 to a stop.

As an alternative to a stop signal, the second type signal may comprise a coast signal, which designates that the coast signal allows the forklift 10 to eventually come to a stop. For example, if controller 103 recognizes a coasting signal as a valid coasting signal, then controller 103 can decouple drive with forklift 10, for example,

JL JL

IMS '! 'instructing the traction controller 106 to stop applying a signal to drive the traction motor 107, allowing the forklift 10 to coast and gradually slow to a stop. Controller 103 may consider any number of reasonable conditions or factors to interpret and take action in response to received stop or coast signals. Furthermore, instead of remote control device 70 transmitting a signal of a second type to request that forklift 10 to implement a particular function, remote control device 70 can transmit multiple instances of the signal of the first type, i.e. , if a button on the remote control device 70 is double-clicked to request that the forklift 10 implement a particular function, as will be discussed below.

The time it takes to bring the forklift 10 to a complete standstill may vary, depending, for example, on the intended application, environmental conditions, the capabilities of the particular forklift 10, and other similar factors. For example, after completing an appropriate travel motion, it may be desirable to allow the forklift 10 to coast some distance before coming to a stop, such that the forklift 10 comes to a slow stop. This can be achieved by using regenerative braking to slow the forklift 10 to a stop, such that a predetermined range of

Alternatively, a braking operation may be applied after a predetermined delay time to allow the forklift 10 to have a predetermined range of additional travel after the start of the stopping operation. It may also be desirable to bring the forklift 10 to a relatively quicker stop, for example, if an object is detected in the path of the forklift 10 or if an immediate stop is desired after a successful creep operation. For example, the controller can apply a predetermined torque to the braking operation. Under these conditions, controller 103 instructs brake controller 116 to apply brakes 117 to stop forklift 10.

Furthermore, if a forklift disable function is implemented, the forklift can stop with maximum braking torque. For example, wireless remote control 70 may include a disable control that transmits a message instructing forklift 10 to brake and / or shut down. In response to the disable function, the forklift 10 may also disconnect a main contact 118 that is used to power the forklift 10. Under this configuration, the forklift 10 may require a restart operation, for example, through the use of a key switch or other.

Controller 103 can also interact with other forklift outputs 119 to implement desired activities, for example, to control a horn, light source, display, etc. As such, controller 103 can interact with different components of forklift 10, with the operator, and with wireless remote control devices 70 to implement different travel, stop, coast forward, and power enable strategies.

As noted above, controller 103 can communicate with brake controller 116 to cause brake settings 117 to bring forklift 10 to a stop under various conditions. For example, the emissions from the object sensors 76 can be nullified while the operator is driving the forklift 10, for example, to allow the operator to navigate the forklift 10 in tight spaces and around corners, which might otherwise activate one. or more of the object sensors 76. However, the emissions from the object sensors 76 may be effective and would not cancel out when no operator is detected on the forklift 10. As such, controller 103 may communicate with brake controller 116 to stop forklift 10 if controller 103 determines that there is an object in the travel path of forklift 10, for example, as detected by object sensors 76 during the tour in response to the receipt of

Additionally, controller 103 may refuse to implement a ride request in response to receiving a ride signal from a corresponding wireless remote control 70 if platform presence sensors 58 detect the presence of a person on the forklift, or wherein the load presence sensors 80 indicate that a corresponding pallet, for example, a pallet, is not in position on the forks of the forklift. Still further, the controller 103 may communicate with the brake controller 116 to stop the forklift 10 if the load presence sensors 80 detect a pallet shift from a valid designated position.

Remote control device 70, receiver 102, and transmitter 109 can communicate over a range of frequencies, thereby allowing remote control device 70 and corresponding forklift 10 to be locked on a frequency or frequencies that have minimal interference from external sources. Additionally, any number of wireless technologies can be used to facilitate interaction between the forklift 10 and the remote control device 70, including the use of spread spectrum technologies.

As an example, technologies such as a Bluetooth communications link or a derivative thereof can be formed, among

<img file="MX354755B_D0016.tif" />

<img file="MX354755B_D0017.tif" />

the transmitter of the remote control device 70 and the forklift 10. Bluetooth technology and similar communication allow control over remote output power intensity, adjustable output power, multiple sub-channels, and frequency hopping to reduce the probability of noise and other interference in the work area. Bluetooth bandwidth can also simplify voice transmission control, as will be described in greater detail herein.

IF the forklift 10 includes a tiller arm instead of the steering control shown, the forklift may include a steering arm brake. As such, a steering arm lock device may be provided to place the forklift in a coasting mode of operation when using the remote control device, for example, as disclosed in US Pat. United States of America

Number 6,595,306, assigned to the same assignee, and which is hereby incorporated by reference.

Referring to Figure 3, the remote control device 70 and the corresponding receiver 102 can be configured such that the wireless control is operable over a predetermined distance. Forklift 10 is located in a typical warehouse aisle 120 having a plurality of storage locations 122 on either side of aisle 120. As illustrated, remote control device 70 is capable of doing so. i 9999

... Β, 5ητυτο.Μί.χτ; .ν; τ communicate with forklift 10 over a dotted path radius range 130. The range may vary depending on a particular implementation. For example, an operating range may depend on an anticipated distance an operator is expected to walk from forklift 10 to pick up an item during a picking process. In an illustrative example, this distance can be approximately 25 feet (7.62 meters). Furthermore, the operating range need not be the same in all directions or under all conditions. For example, the operating range may have a pattern that is elliptical or some other directional pattern, etc. Still further, there may be a minimum range within which the wireless remote may not be functional. As described above, controller 103 can discriminate signals that are too strong, suggesting that the operator is stationary or in too close proximity to forklift 10 for remote operation. As yet another example, the operating range can be affected by operating conditions and environmental conditions, such as the speed of the forklift, when the forklift is located within a facility, etc.

It may be desirable to set or otherwise program the range of the object sensors 76 to detect obstacles in the path of the forklift 10, which it is traveling in response to receiving a request for a course from the remote control device 70. By example, as shown,

ΒβΤίΤ'Ρ-::: /: 'each of the object sensors 76 set ^ jáana.iJdeteddayxY' * objects on their path within a _ distance. . -giie. — is—— schematically suggested by the range designated by the dotted detection area 78 next to each object sensor 76. Object sensors 76 located on the sides are not illustrated in Figure 3 for clarity of the discussion. The range of the object sensors 76 can also be configured to change either statically or dynamically. For example, the range of the object sensors 76 may change as the speed of the forklift 10 changes in response to received travel commands, etc.

For each actuation of the ride request on the remote control device 70, the operator can advance the forklift 10 without taking the time to physically engage the forklift 10 controls. For example, after issuing a ride request via the remote control device 70, the operator may walk to the next item to be retrieved, or may carry out some other task. The forklift 10 automatically travels forward by an amount corresponding to the request for travel. For example, if a trip is commanded for a predetermined distance, after traveling the predetermined distance, the forklift 10 stops, without requiring a separate control action from the operator.

Alternatively, the forklift 10 can stay in motion for as long as a command is issued.

movement by remote control device 70, for example, by maintained actuation of a travel button. Under the latter configuration, the forklift 10 continues to travel until the operator releases the travel button, the operator actuates a stop or coast button, a specified maximum continuous travel expires, or some other appropriate action stops the forklift 10.

As an example, in a first optional way in which the operator can interact with the forklift 10, it is assumed that the operator travels the forklift 10 down the aisle 120. A first row 142 of storage locations 122 is located at a first side of forklift 10. A second row 144 of storage locations 122 is located on a second side of forklift 10. Each of the first and second rows 142, 144 of storage locations 122 include a plurality of storage areas, which may be containers, pallets, delineated or otherwise designated areas, and the like. Furthermore, each storage location 122 may comprise several independent storage areas that are vertically stacked, such as in a rack system in a warehouse facility or distribution center. As such, there may be multiple levels of storage at each storage location 122. During automatic operation of the forklift by means of the remote control device 70, the forklift 10 travels down the aisle 120. For example, the forklift 10 is illustrated traveling with the unit of

Therefore, the forks 1 · 6 »are-n> haei» · »! rá-ft of the forklift 10 when traveling under the remote control. Other directions of travel can be implemented in an alternative way.

It is assumed that the operator is initially located at position, and that the item to be picked up is at the location 122 designated as storage location 122-1 in column 144. The operator walks from position A, to the storage location 122-1 to retrieve the desired pickup item. After picking up the desired items, the operator is in position B, which is directly across from storage location 122-1. It is further assumed that the operator has advanced or is in the process of advancing the forklift 10 using the remote control device 70 such that a pallet 146 which is positioned on the forks 16 of the forklift 10 is located at position C , which is in the vicinity of position B. The operator need not carry any items from the pick-up order to forklift 10 when walking from position A to storage location 122-1. Furthermore, by the time the operator reaches position B with the items picked up from storage location 122-1 (or shortly before or after), the forklift 10 has come to remain in position C. Consequently, the operator only needs to load the pickup items a relatively short distance from the

INSTITUTE n / 7 storage location 122-1 to position B. ^{of the}i £ dustrial

After placing the pickup on the pallet 146 of the forklift 10, the operator can then ride on the forklift 10 to drive it to the next location, or if there are additional items to be picked up in the aisle 120, the operator can move the forklift 10 using the travel control of the remote control device 70.

Continuing with the previous example, it is assumed that the operator is now in position B, and that the item is to be picked up from storage location 122 designated as storage location 122-2 in row 142. The operator walks from position B to storage location "122-2" to retrieve the desired pickup item. Furthermore, the operator initiates the ride request on a wireless remote control, for example, by using the remote control device 70 which wirelessly transmits a first type of signal (tour) to the receiver on the forklift 10. By the time the operator reaches position D with the item picked up from storage location “122-2” (or a little earlier or later), the forklift 10 has traveled under the wireless remote control from position C and has come to stay at position E, which is in the vicinity of position D. Again, the operator places the picked item on the pallet 146 of the forklift 10 in such a way as to minimize the distance the operator must walk while loading the order items of:> 'Λ' 3: ./ 33

pickup.

Furthermore, when moving the forklift 10 forward! i in traja., collect, the time required to collect from aisle 120 can be reduced because the operator does not need to interrupt the collection process to reposition or reorient the forklift 10. Still further, as schematically illustrated, a single drive of A travel control on the remote control device 70 can cause the forklift 10 to advance a distance S1 and then stop. As such, after operating the travel control by means of the remote control device 70, the forklift 10 is positioned in a convenient location for the operator to place the previously collected items, thereby minimizing the distance the operator must load collected items. Furthermore, because the operator does not need to interrupt picking or other work-related tasks, the operator can save energy and time to complete a given task, for example compared to an operation that requires the operator to stop. continuously work to advance the forklift to the next location.

One measure of an operator's productivity is the time the operator spends in the collection phase. That is, how much time is spent picking up the orders compared to the time spent relocating the forklift 10 and performing other tasks not immediately related to locating and loading the pickup items. As is evident from the previous discussion, the βτπ · ': ·· / i

This minimizes the distance the operator must travel to reach and pick up items, and further reduces the distance the operator must walk while loading the pickup items. This can become significant, especially when the forks 16 of the forklift 10 are relatively long. For example, certain forks 16 can support loads three times the length, such as three pallets.

Furthermore, the warehouse management system software that directs operators in their picking operation can take into account the remote control of forklift 10 when planning picking orders, so that the benefits of the picker can be enhanced. remote control through a more efficient metering process when picking orders are prepared.

Referring to Figure 4, in accordance with one aspect of the present invention, additional features may be incorporated into the warehouse or other facility and / or forklift 10 to provide improved functionality. For example, the remote control travel control functionality may be disabled in certain locations within the facility, such as at the end of a hallway, at the intersection or

I f *^τ^τ o ¿¡7 · .: yy '' Rt-RR / R intersection of roads, in the areas of the bays'^Fde''ca rg reception, in high traffic areas pea tona Γ ^ Τε'ΓΡ^,5Γ3ΊΓϊ1δΓΓ5Γ '' “this functionality, it is assumed that the remote control travel control is disabled on forklift 10 while forklift 10 is approaching the end of aisle 120. To facilitate disabling the wireless control travel control of forklift 10 At a predetermined location, the forklift 10 includes one or more devices 148, such as radio frequency identification (RFID) antennas. The corresponding RFID 150 markings are placed at the end of the corridor in a suitable position.

Devices 148 generate signals in response to the end-of-aisle detector, for example, sensing the corresponding RFID markings 150, which causes the forklift 10 to stop if it is under the travel control of the remote control.

For example, signals from devices 148 can be coupled to corresponding inputs, eg, those appropriate for inputs 104 on controller 103. For example, if the controller 103 detects an appropriate signal from one of the devices 148 and the controller 103 detects that the forklift 10 is currently being operated in response to a request for travel from the remote control device 70, the controller may send a appropriate command to brake controller 116 to stop forklift 10.

In the illustrated example, aisle 120 is 15 feet

ΙΜΡΪ

INSTITUTO MEXICAN ~> 'Λίΐ * !!?

(approximately 4.6 meters) wide and the antennas are configured to detect the corresponding Hp rfir 15 están breasts within a radius of 13 feet (approximately 3.9 meters). This provides sufficient overlap of coverage in the aisle 120 for the detection of the forklift 10 and provides a wide distance for the example forklift 10 to stop or otherwise come to a stop approximately at the end of the aisle. In practice, other ranges may be used and may be varied, based, for example, on the stopping requirements of the forklift 10 and the corresponding Implementations of the Wireless remote control, the sensing technology used, and other suitable factors.

Referring to Figure 5, a method 200 for implementing the traversal function is illustrated. Method 200 can be implemented, for example, by controller 103 on forklift 10. As described herein, controller 103 can respond to receipt of a request for travel from remote control device 70 to advance the driver. forklift 10 unless a condition is satisfied. Method 200 establishes several example vehicle conditions that can affect how controller 103 interprets the remote control device 70's request for a ride.

The process waits to receive a tour request at 202.

If a tour request is not received, the process continues on hold. IF a tour request is received, the process can now h% y

208 and 210.

For example, the process may require the forklift to stop before recognizing a new request for travel. This vehicle condition requirement can be implemented, for example, where the controller 103 limits the maximum amount of continuous travel of the vehicle without stopping when under the wireless remote control in response to the reception of the signals of the first type ( tour request). In this regard, controller 103 can determine if the forklift is stopped at 204, for example, using feedback from a decoder or other suitable device to detect forklift movement. If the forklift is not stopped, the process can optionally wait for the forklift to stop or the process can ignore or otherwise terminate the evaluation of whether it implements the received tour request as indicated by the hatched lines.

Furthermore, the process may require that not only is the forklift stopped, but that there is no movement of the forklift for a predetermined period of time. Therefore, for example, if the forklift is stopped, the process can determine if a previously determined interval has passed

The process can also review 208 vehicle conditions, such as operational conditions and / or environmental conditions that may affect forklift operation in response to the request for travel from the remote control device. If the vehicle condition verification indicates that it is satisfactory to proceed with the processing of the received tour request, then the process continues. Otherwise, the process can wait for the condition to resolve, or the process can ignore or otherwise finish processing the received tour request as indicated by the hatched lines.

Operational and environmental conditions that can cause the process to ignore or otherwise reject the implementation of a walk-through request from remote control device 70 may include factors such as detecting an operator on the platform, detecting an object on the platform. forklift travel path, detect that the forklift is in an area or location where wireless remote control is not allowed, for example, at the end of the corridors or in the

described with reference to Figure 4, detect the lack of tarim-e or other suitable conveyor structure on the forklift forks, detect that an Invalid operator has registered with the forklift and / or that the forklift is linked to a user unauthorized, detect that the energy level is out of range for the received tour request, for example, too weak, indicating that the operator is out of a previously determined maximum range, or too strong, indicating that the operator is too close to the forklift, etc. Consequently, the operator may have to wait, clear an obstacle, or otherwise remedy the condition before the forklift is ready to respond to remote route requests.

The process can also verify that the forklift's steering angle is within the range of steering angles previously determined in step 210. If the forklift's wheels are steered beyond the previously determined angle, the steering angle can be corrected by step 212. Alternatively, the system can put the steer wheel in a predetermined position, for example, directed forward, or the system can ignore or otherwise terminate processing of the received drive request.

The forklift then moves to step 214. For example, if each evaluated vehicle condition is satisfied by the '- <7>

controller to allow remote travel, the control will H ^ W «f the traction control system moves the forklift forward · The forklift can also sound an alarm or provide other form of audible or visual signals when the forklift is in response travel to wireless remote control commands, or when the tour control on remote control device 70 remains on, such as by use of light source 68 and / or indicator such as strobe 72. As additional illustrative examples, a horn and / or other signal may be controlled by relays or other suitable switching devices to be concomitantly active. with the action of the traction motor while the forklift operates in response to commands from the wireless remote control.

The process checks in step 216 to determine if a stop incident has occurred. For example, the process may check to determine if the operator has disabled travel control on remote control device 70. After travel control is disabled, the forklift is stopped, for example, by applying a brake, for example. inertia, or carrying out other suitable stopping operations. The process may also check in step 216 to determine if the travel time, travel distance, or other similar incident has passed in response to vehicle movement in response to the wireless remote control.

For example, the forklift can be configured to tour

As another example, the forklift can be configured to travel a maximum distance of continuous motion in response to successive repeated requests for travel from the wireless remote control. An example range may comprise a limited travel distance of 25 to 50 feet (approximately 7.6 meters to 15.2 meters). As another example, the forklift can be configured to travel for a predetermined maximum continuous travel time.

Other example stop incidents may comprise vehicle conditions, such as those imposed by previously defined travel limits, receiving a stop or disable command, detecting an obstacle in the forklift 10's travel path, detecting a person on the forklift, detect a change in the position of the load-carrying device (for example, pallet, collection cage), detect mechanical, electrical, abnormal pneumatic, or hydraulic of the forklift, etc. If the previously determined stop incident is reached in step 216, the forklift is stopped or coasting to a rest in step 218 and the system is reset. If the operator sends a tour request from a wireless control device 70 before a task is completed, the system can wait for the current task to complete before issuing the next command.

According to various aspects of the present invention al. remote control device 70 is a wireless remote control device that is used by the operator who interacts with the forklift. In general, the portable wireless remote control device may comprise a wireless transmitter and a course control, eg, a button or switch that is coupled in a communicable manner with the wireless transmitter. As will be described in greater detail later, actuation of the travel control causes the wireless transmitter to transmit a first type of signal, which may request the forklift to move in a first direction. Depending on the particular implementation, the wireless remote control device may further include an electrical unit such as a battery to power the electronics of the remote control device, a control area where the path control is located at the operator, for example, on or around the operator's hand, and a communications link between the transmitter and the control area where the transmitter is physically separated from the control area when used by the operator.

Referring to Figure 6, an example garment 250 comprises a glove-like structure carried by an operator's hand. The illustrated garment 250 includes a first control area 252, a docking area 254 that supports a detachable transmitter and power source, and a "μτ" "ί" ·· αλ λ communications link implemented as a 256 circuit. que'InlerconeqtgiteJ¹'the first control area 252 with the coupling area. As shown, control area 252 includes a first control 258, for example, a button that faces toward the finger portion of the garment 250. In an illustrative example, the button extends from the finger of the glove. where the forklift operator's finger extends when the garment 250 is properly carried. The orientation of the button provides the main face of the button juxtaposed with the forklift operator's thumb. As will be described in greater detail below, this configuration allows the forklift operator to reach out and actuate the first control 258 using his thumb, and consequently makes it possible to operate the remote control device 70 using a single hand gesture. Furthermore, as will be described in greater detail later, this hand gesture can be performed even when performing operational job tasks, such as holding or carrying boxes, scanning devices, tools, etc.

Coupling area 254 includes a plurality of contacts 260 that are electrically coupled to first control area 252 via circuit 256. As an example, circuit 256 may comprise a flexible circuit that is integrated or otherwise hidden in the material of construction of the garment 250. The circuit 256 further supports one or more antennas 262. The docking area 254 is configured to receive the device for

IMPI institute 'c + c.'. And or corresponding releasable communications 264. For example, communications device 264 may comprise contacts that mate with contacts 260 in the mating area when communications device 264 is properly attached to garment 250. Communications device 264 can be instantly adjusted, locked, or secured using a hook and loop fastener, such as a cloth or hook and loop material, or a material sold under the registered trademark Velero® by Velero Industries, Manchester, New Hampshire, USA, secure using magnetic forces or other suitable techniques.

Referring to Figures 7A and 7B generally, the communication device cover 264 has been removed to illustrate an example configuration of the components on a first surface (shown in Figure 7A) and the components on a corresponding second surface (shown in Figure 7B) of a circuit board of the communication device 264. Communications device 264 comprises carrier 270, for example, a two-sided printed circuit board including, on a first side thereof, regulator circuitry 272 to regulate power used to operate communications device 264, 274 visual display indicators such as Light Emitting Diodes (LEDs) that provide visual feedback of the operation of the monitoring device.

The carrier further supports on a second side thereof, a battery 282, a communications circuitry 284 such as a transmitter, receiver, transceiver, etc., and the contacts 286 communicate with the mating area contacts 254 when the Communications device 264 is fitted in a corresponding garment 250.

The visual display indicators 274 can be used to provide visual feedback to the operator on the status of the remote control device control system. For example, the first of the indicators can be used as an indicator of a fault condition. For example, an LED can illuminate an X symbol centered in a circle (best seen in Figure 6) to indicate a fault condition such as where the Go 258 button is not connected, where either button has a short or failure, where the radio link is down, where you cannot find a receiver ID paired with the transmitter as will be explained in more detail later, etc. Another indicator 274 can be used to indicate a low battery represented by a battery icon, best seen in Figure 6. Other uses of the indicators can be implemented, and more or less than two indicators can be provided. The remote control device 70 may further include alert elements

Additional features such as sounds from the désfáíé screen ^^^ sfe ^^ Feature photos that provide a visual and / or audible signal about the status of the remote control device and / or associated forklift 10.

The input components 276 may comprise, for example, two buttons. The first of the buttons may correspond to a horn button. When the horn button is pressed, the corresponding message is transmitted to receiver 102 on forklift 10 to sound the horn of the forklift. The second of the buttons may comprise an emergency disconnect button. Pressing this button causes an emergency shutdown command that is transmitted to receiver 102 on forklift 10. In response to receipt of the emergency shutdown command, forklift 10 can be stopped and shut down, thus requiring the operator to stop. Restart the start-up procedure to restart the forklift as described in more detail herein.

The transmitter in communication circuitry 284 can transmit information in analog or digital form using any suitable registered or standardized wireless transmission format. For example, transmission can be done using existing technologies, such as 802.11, 802.16, Bluetooth, Short Message Service (SMS), Amplitude Shift Keying (ASK), Digital Amplitude Modulation (OOK), Local Area Network wireless (WLAN), inst> and code division multiple access (CDMA), amplitude modulated (AM), ffiáddbíta frequency & a universal mobile telecommunications system (llMTR), cell phone technology such as global system for mobile communications (GSM), etc. In practice, the way the transmitter transmits messages must correspond to the format that is recognizable by the corresponding receiver on the forklift.

10. Furthermore, the communication circuitry 284 of the remote control device 70 may also contain its own receiver for two-way communication with the corresponding forklift 10.

When the communications device 264 is properly attached to the corresponding garment 250, the remote control device 70 provides a convenient platform to allow the forklift operator to control his vehicle remotely. For example, a user may operate Go button 258, which communicates with processor 278 of communication device 264 via circuit 256 and corresponding contacts 260 and contacts 286. The "Go" button causes processor 278 to format and transmit a ride request that will advance the forklift if the ride request is received by the forklift and determined to be a valid command.

If the ride request is properly received by receiver 102 and determined to be a valid ride request, forklift 10 can be wirelessly controlled j / p and vo x Y · '-n remotely for a time and / or distance. prescribed, and then PST ^^ geHs ^^ siZ controlled braking or coasting described in greater detail herein. The button 258 can alternatively facilitate the travel of the forklift 10 for as long as the button 258 is pressed (or until an intervention incident occurs, such as the forklift 10 reaches its maximum travel distance, travel time, detect an environmental or operational condition that stops the forklift, etc. Control area 252 and / or communications device 264 may also optionally include driving and / or steering controls to provide commands to the forklift to adjust the steering angle of the forklift as described in greater detail herein.

Still further, an optional stop button may be provided, for example, within control area 252 and / or on communication device 264 to stop the forklift, which may be useful where the coasting function is implemented. . If the stop command is properly received by receiver 102, forklift 10 will be controlled to a controlled stop. Alternatively, an optional additional button may correspond to a coast forward command, which, if properly received by receiver 102 on forklift 10, will cause forklift 10 to coast to a stop.

When any of the buttons on the device is pressed

; -s and transmits the resulting signal via transmitter 284 to receiver 102. In this regard, processor 278 may append to the command a sequence, control or other identifying information, a time stamp, channel indication, or other data necessary to for receiver 102 to discriminate that particular remote control device 70 is a valid communications device, to authenticate operators, to record historical data or other purposes, etc.

While remote control device 70 is illustrated as a glove that is worn by the operator around the wrist or arm, other configurations can alternatively be implemented. For example, the transmitter, power source, and / or any of the one or more controls, such as button 258, can be worn separately or together anywhere on the body that is comfortable, practical, or desirable, such as dictated by the specific request. For example, as shown, garment 250 is worn by the corresponding operator. As such, each operator may have their own glove that contains the button 258, circuit 256, and antenna (s) 262 integrated within it. When the operator begins a shift, a communication device 264 can be retrieved from an appropriate charging station or other stopping point, and docked with the corresponding docking area 254.

By separating the communications device 264 - 6 from the garment 250 and the corresponding button 258, a single transmitter with multiple instances of the garment 250 is enabled. As such, operators on different shifts can maintain their own garments 250, including finger and hand controls, eg, button 258, and simply plugging or docking a communications device into your garment 250 at the start of your shift. This further allows for the incorporation of identification technologies such as Radio Frequency Identification (RFID) tags that are incorporated with the garment 250, the information of which can subsequently be transmitted to the forklift 10. As such, the forklift 10 can record the operator, productivity, or other relevant information during the operation.

Referring to Figures 8A and 8B, the button 258 of the remote control device can be easily reached and operated with the corresponding thumb of the operator, as schematically represented by the directional arrows. This action requires deliberate, yet easily achievable action on the part of the operator to actuate the button 258. Furthermore, operational sequences may be required to actuate the button 258. For example, double pressure in rapid succession, ie, double click, may be required to actuate a control, as will be discussed herein. The remote control device 70 can be used in such a way that neither hand of the forklift operator will inconvenience or otherwise interfere with an operator using both hands to pick up items. More faith faith,

-. -, A fe., Fe \ nsr-τυτο JY-.ffe'fe! what ewiQJSEvg ráfwtaafe-i ^ yet, there is no inconvenience, such as requew ^ uWiOS¹limb movements, elusive or otherwise inaccessible controls for moving or stopping the forklift 10, even when the operator's hands are currently engaged in a picking operation. As such, the operator can move or stop the forklift 10, even when loading large items, such as boxes, etc. with both hands, using a single simple gesture.

In accordance with one aspect of the present invention, an area 288 around the button 258 may include a raised / contoured collar. To actuate and / or select button 258, an operator must press down in the direction of the arrow illustrated inside the collar, and actuate button 258. As yet another optional configuration, button 258 may require multidimensional operation before successful actuation is transmitted. For example, button 258 may require to be depressed, and then slide in a lateral direction generally orthogonal to the direction in which the button is depressed.

Garment 250 can be constructed of any number of materials, such as stretch fabrics, plastics, synthetics, leather, or other materials alone or in combination. Furthermore, the different components of the remote control device 70 can be worn as an arm band, as a belt or a device attached to the shirt, or by other means. Furthermore, the communications link that connects the control area with the transmitter in the garment is relatively thin than retractable.

<img file="MX354755B_D0022.tif" />

Button 258 can be positioned under a spring loaded rocker member, which can be manually slid down to expose button 258. In addition, button 258 can optionally be programmed to support multiple commands. For example, remote control device 70 can be configured to transmit a "stop command" if a single push of button 258 is detected. Furthermore, a scroll command can be transmitted if a double click or double actuation of the button 258 is detected within a predetermined time period.

Alternatively, instead of transmitting different types of signals corresponding to each respective requested command, e.g., stop, walk, etc., remote control device 70 may transmit successive single or multiple instances of the same signal based on the number of clicks implemented by the operator, where the controller 103 on the forklift 10, after receiving the signal instances, decides which command to actuate, if any, based on the number of received signal instances and / or current vehicle conditions, for example, whether the forklift 10 is currently moving under the wireless remote control or is stopped.

For example, a single click of a button on the device

ΚΛ vi I '.O' ¿el J „';

remote control 70 by the operator can cause a single instance of a signal to be transmitted by the remote control device 70 to the forklift 10, and a double click of the button by the operator can cause a double instance of the signal to be transmitted by the device remote control 70 to forklift 10. The single instance of the signal can cause the forklift 10 to implement a stop function, and the double instance of the signal can cause the forklift 10 to implement a travel function as described herein, although instances of the signal can causing the forklift 10 to implement other previously defined functions, as described herein.

As another example, the controller 103 of the forklift 10, after receiving one or more instances of a signal, can evaluate the condition of the vehicle and implement a particular forklift function based on the number of instances of received signals and the conditions of the vehicle. . In this example, a single click of the button by the operator can cause a single Instance of a signal to be transmitted via the remote control device 70 to the forklift 10, and a double click of the button by the operator can cause a double signal instance via remote control device 70 to forklift 10. A single instance of the signal can cause the forklift 10 to implement a stop function if the forklift 10 is moving under the wireless remote control after the forklift 10 receives the signal. A double instance of the signal can also do

INSTÍTUtC MEXICANO DB THE INDUSTRIAL PROPERTY that the forklift 10 implements a stop function forklift 10 is moving under the wireless remote control after the forklift 10 receives the signal. If the forklift 10 stops after receiving the signals, a double instance of the signal may cause the forklift 10 to implement a tour function while a single instance of the signal may not cause the forklift 10 to implement the tour function, that is, the forklift 10 ignores the signal.

Alternatively, redundant travel controls may be provided on communication device 264, which controls may be independently depressed or may be programmed to require concomitant actuation to move forklift 10. As such, the communications device 264 can be worn on the operator's arm, for example, just above the wrist or anywhere easily accessible, such as on a belt, shirt, or pants, in which case, the communications device 264 can be attached with a suitable wiring harness to button 258. Still further, short-range wireless technology, such as Bluetooth, can be used to enable a communications device 264 to communicate with the garment 250 and the corresponding button 258, allowing the communications device 264 to be carried by the device. operator moving away from garment 250 and corresponding button

Under this configuration, button 258 may comprise a pair of Switches Implemented as textured rubber surfaces on opposite sides of remote control device 70. As such, an operator must depress remote control device 70 to operate travel control. By having two switches, concomitant actuation of both switches may be required. This also allows the transmitter, power source, and controls to be integrated into a single housing, thereby minimizing the interference of the remote control device 70 with the operator, for example, eliminating cables and other structures that may loosen. or that may be inconvenient for the operator. To operate a stop or coast control, the operator, for example, can hold the earring and pull the remote control device 70 in a downward direction. The downward force causes the transmitter to transmit a stop or coast forward command, depending on the particular programming. The portable remote control device 70 is used by sliding the lanyard around the operator's neck.

In accordance with another aspect of the present invention, remote control device 70 can be used by attaching remote control device 70 to a shirt, belt, pants, vest, uniform, or other garment, using a suitable bra. This example configuration provides another vi p.

Furthermore, the fastener allows the operator to attach the remote control device 70 to any convenient item of clothing or other suitable location on or around the operator. The bra can also be attached to a lanyard to be worn around the operator's neck. A generally round and smoothly shaped configuration of the remote control device 70 can allow for a relatively low profile design that is used well, because the remote control device can be carried in a way that positions the remote control device 70 close to the operator's body.

In accordance with yet another exemplary aspect of the present invention, remote control device 70 may be implemented as a voice-controlled transmitter. The remote control device 70 can be mounted, for example, on a torso strap or other suitable device. Remote control device 70 further comprises a microphone. The microphone can be rotated or otherwise adjusted to provide flexible placement of the microphone input for the operator. Although voice activation is provided, a redundant stop or coast button may also be provided. This configuration provides for flexible placement of remote control device 70 on the operator. Furthermore, the remote control device can be operated in a hands-free mode. Preferred voice commands are a simple set of commands.

When used with the control system^Gaveand $ yfeft'¿ remote control device 70, the operator's voice can be used for commands such as TRAVEL, FORWARD, COAST, STOP, etc., to make the forklift 10 move for a previously set distance and still hold the orientation established by the direction controller 112 (shown in Figure 2), for example, parallel to the storage locations 122 in the aisle 120. The command words TRAVEL, FORWARD, COAST, STOP, etc., can be used to communicate with the traction motor controller 106 while the steering controller 112 automatically corrects itself to maintain a straight or other desired orientation. . The remote control device 70 may further allow the operator to make minor adjustments to the orientation of the forklift 10, for example, by allowing voice commands such as LEFT or RIGHT to adjust the orientation of the forklift 10. Herein, the translation From voice commands to control commands for the forklift 10 can be carried out either in the processor of the remote control device 70 or in the controller 103 of the forklift 10.

Still another alternative configuration for the remote control device comprises a variation on the thumb-activated button 258. Instead of a single button, two buttons are provided. The first and second buttons each comprise a first component of the switch and also share a second

In particular, a first band or finger is held, for example, to receive fluid from the forklift operator, and which supports the first component of the first button switch and the first component of the forklift switch. second button, for example, as recesses. When wearing the garment, the first switch components are oriented toward the operator's index finger side. A first contact button is provided generally along the base of the recess of the first component of the Switch. In a similar manner, a second contact button is provided generally along the base of the recess of the second switch component.

In a corresponding manner, the garment includes a band that supports the second component of the common Switch near the thumb of the operator. The second switch component includes a common contact generally at the tip of a protrusion that generally corresponds to the recesses of the first switch components of the first and second buttons. To actuate the first button, the common contact on the operator's thumb leads to an intimate electrical connection with the first contact button, for example by directing the protrusion of the second switch component into the recess of the first switch component. When electrical contact is made between the first contact button and the common contact member, actuation of the corresponding control is achieved. In a similar way, to actuate the

second button, the common contact on the operator's thumb, to an intimate electrical connection with the second button, for example, directing the protrusion of the second switch component into the recess of the first switch component. When electrical contact is made between the second contact button and the common contact member, actuation of the corresponding control is achieved.

Any of the disclosed configurations for remote control device 70 may be equipped with steering trim controls. For example, remote control device 70 may include additional controls within the control area, such as a left direction button and a right direction button in addition to the travel button and the optional stop or coast button. The amount of remote controllable steering correction will depend on a number of factors such as environment of use, typical anticipated correction, etc. However, in an example configuration, small steering angle corrections, eg, on the order of 1 degree or less, can be implemented for each actuation of the left and right steering controls.

In addition, the remote control system may be integrated with a forklift steering angle control 10. The steering angle control is typically implemented using a potentiometer, encoder, or other input / Vi device. jr X

INSTITUTO MEXICAN!) YX-.N OF PROPERTY V \ ¡* ea ** suitable, and can be placed in any convenient location¹ on the forklift 10. When used in combination with RfSP additional steering controls, the steering angle control sets a desired orientation of the forklift 10. As an example, an operator can align the forklift 10 in an aisle parallel to a row of shelves in a warehouse operation. Using the angle sensing feedback from the steering controller 112 (shown in Figure 2), the orientation of the forklift 10 can be kept parallel to the shelves as the forklift 10 moves down the aisle. The steering angle control, therefore, prevents the forklift 10 from drifting and maintains its course. Under this configuration, a request for travel from remote control device 70 causes forklift 10 to travel substantially straight on the orientation defined by the steering controller.

A system that implements the functionality of the displacement control provided herein may implement additional advanced features to meet performance requirements. For example, transmitters may be equipped with a global stop command that turns off all forklifts 10 within range of the transmitter that are operating under remote control. Accordingly, all receivers can be programmed or otherwise configured to acknowledge the stop command, for example, using a global or common script. Furthermore, the command of ϊ Μ ΡI

KIXICANO INSTITUTE Yh D5 La!>? Or? Ir: 'Aii V \ »_and global stop can be transmitted by appending a l, D of the^iNoperator ^ so that the identity of the operator that * sends the global stop command can be identified.

In each of the illustrated example systems, an antenna for the transmitter could be located in a transmitter box, sewn into the garment, for example, integrating the antenna into Sailboat, straps, bands, or other components associated with the transmitter, which is carried by the operator, located in the wiring between the transmitter box and the controls, etc.

Still further, the transmitter can be directional. For example, a target may be provided on forklift 10, for example, as part of receiver 102 or antenna 66. Accordingly, the operator must point the transmitter of the remote control device 70 at or toward the target to make the operation of the control, for example, a travel command, is received by the forklift 10.

Alternatively, certain commands may be non-directional, where other controls are directional. For example, global arrest (when provided) may not require detection of a target to take effect. On the other hand, a control to initiate a scrolling operation may require the detection of a suitable target. Target detection can be performed, for example, using infrared technologies or other suitable technologies.

If the operator has not done this, the garment is also carried by the operator.

The forklift operator then initiates a power-up sequence to enable the forklift to operate, that is, the operator starts the forklift at step 306. When starting the forklift, the operator may be required to provide a login identification code to the forklift. lift truck. This identification can be provided, for example, by entering a personal identification number (PIN) into a forklift control panel, using a key fob to provide the forklift's entry ID, or the operator's PIN can be encoded into a forklift device. memory, such as an RFID chip embedded in the garment of the remote control device worn by the operator.

This information can be useful, for example, to validate the commands received by the receiver on the forklift, to record data for subsequent analysis, to record productivity, forklift performance, etc.

Referring to Figure 10, a method 320 is illustrated for a forklift operator initiating a shift using the remote control device in accordance with various aspects of the present invention. The forklift operator obtains a communications device from a suitable storage area at 322. As with the previous example, the communications device may be stored in a battery charging station, etc. The forklift operator loads the communications device onto the garment at 324. The communications device is then caused to begin transmitting a pairing mode trust tone at 326. For example, the trust tone may comprise repeatedly transmitting a message. It must include the Identification of the transmitter. In this respect / aspect? ”^ Identification code of the transmitter being transmitted may match a transmitter identification code that is written on the communications device or is otherwise known to the forklift operator.

The forklift operator starts the forklift at 328, which may comprise registering with the forklift as set forth in greater detail above. The forklift operator can then enter a pairing mode at 330 to synchronize the forklift receiver with the particular transmitter retrieved by the forklift operator. During the pairing operation, the receiver in the forklift collects all the trusted tones in its range in 332 and lists the tones, for example, by the transmitter identification code in a suitable visual display. In an illustrative example, the visual display may prioritize the identification codes of the transmitter located by signal strength or by any other suitable measure. The forklift operator selects the transmitter identification code that matches the transmitter code associated with the communications device that was retrieved and uploaded to their remote control device garment at 334. The transmitter identification code selected by the operator is stored in the forklift, for example, in a memory of the controller in the forklift.

The controller on the forklift can eηvi'aY¹^ nBSfetóífe communications device attached to the forklift operator remote control device garment at 336 that includes a unique forklift receiver identification code and / or other information, which can be stored in the memory of the carried communications device by the operator. The transmitter and receiver are then synchronized at 338, for example, as described above. For example, the forklift operator may be asked to press a particular sequence of controls on the remote control device. In response to detecting the actuation of the controls and / or the requested control sequence, the communications device may send a message to the receiver on the forklift that identifies the transmitter identification code, the receiver identification code, and a code corresponding to the controls and / or the requested control sequence, actuated to synchronize the receiver on the forklift with the remote control device carried by the operator.

In this regard, the controller in the forklift may associate the transmitter identification code with the operator identification code that was provided to the forklift controller by the operator as a part of the record in the operation required to start the forklift. The controller can also associate the identification code associated with the forklift / receiver. In this way, the identification code

INSTITUTO MEXICANO of the forklift / receiver, the code of identification^Dy '^; ndí ^ oá> BW of remote control, and the code of ¡HpntificaiAn dai npgradnr ca associated in a unique way. The controller in the forklift can use this three-way association to discriminate received commands. Furthermore, the remote control device also stores the information about the forklift with which it is paired and / or other optional information, for example, an operator identification code, etc., which can be used in the formatting information. and transmission.

Referring to Figure 11, after carrying out work operations, the forklift operator may need to temporarily leave the forklift, for example, to take a break. A method 350 is illustrated for deactivating, re-engaging, and re-synchronizing the forklift receiver and the forklift operator-carried communications device transmitter. The forklift operator turns the forklift off at 352, such as to take a lunch break, etc. After a predetermined time, the forklift operator powers the forklift back at 354. During this break time, the transmitter on the operator-worn remote control device can continue to transmit its synchronized confidence tone, which identifies the transmitter identification code and the corresponding forklift / receiver identification code. The synchronized confidence tone transmitted by the transmitter in the communications device used by the

kept in the forklift's memory the association of the transmitter identification code with the receiver / forklift identification code.

The forklift controller may further require the forklift operator to recognize the system at 358, for example, by entering their PIN code, or providing some other authentication measure to verify that the current operator is the same operator who was using the forklift prior to the break. The pairing is confirmed and displayed in 360 if the operator identification code entered as part of the recognition operation authenticates the operator identification code that was retained in the forklift's memory as the operator who was using the forklift prior to the break. .

For example, the controller in the forklift may maintain the three-way identification code association described above, that is, the forklift / receiver identification code, the remote control device identification code, and the receiver identification code. operator, even when the forklift is turned off. As such, if another operator arrives, that operator cannot use the wireless control of the remote control device with the forklift, even if that new operator comes into possession of the old operator's transmitter, because the new operator does not have the access code. previous operator identification. In a similar way, if a new operator starts the

Ι ~ $ ί ΡΓ _ instituted '-, / · .- ··. > Α forklift and enter a new operator code as part of the forklift start-up process, then the wireless remote tour request issued by the new operator will not be recognized by the controller on the forklift because it does not three-way identification is preserved, meaning the new operator's transmitter will not sync with the receiver on the forklift.

Rather, in order for a new user to successfully use the forklift's wireless remote control features, that new operator must register with the forklift using their operator identification code and use a new pairing mode sync process to sync the new operator's transmitter with the forklift's receiver, such as using the methods described herein.

Referring to Figure 12, a more detailed method 370 is illustrated for temporarily shutting down the forklift, restarting the forklift, and re-synchronizing the transmitter carried by the forklift operator with the receiver on the forklift. The forklift operator deactivates the forklift at 372, for example, to take a break, etc. When the forklift is turned off, a timer associated with the controller on the forklift starts at 374. During the interval where the forklift is off, the transmitter in the communications device carried by the forklift operator continues to transmit its confidence tone synchronized at 376. For example, because the j K4 fc¹ The transmitter has been previously paired with the forklift receiver, the confidence tone may comprise a message that includes both the transmitter identification code and the forklift / receiver identification code. The forklift is activated again at 378. Once reactivated, the receiver on the forklift begins searching for the corresponding confidence tone at 380 that matches the transmitter identification code that it previously stored in memory.

If the synchronized confidence tone is detected within a time limit prescribed in 282, then the pairing is maintained. If the confidence tone is detected to be outside the prescribed time limit, the forklift operator may be required to re-synchronize, for example, employing a start-up procedure, as stipulated in the examples described with reference to Figures 9 and 10. If the pairing is maintained, then the transmitter identification code at 384 can be detected, for example, by receiving a predetermined message from the remote control device's transmitter, such as a re-sync acknowledgment. The forklift operator may also be required to recognize the forklift system at 386, for example, by providing an operator identification code on the forklift, and the pairing confirmation is completed at 388, for example, by displaying a confirmation to the operator of the forklift. lift truck.

Under this configuration, if another forklift user 10, that new user will have to clean and re-synchronize the forklift receiver with the new remote control device transmitter identification code carried by the new operator. However, if the new operator tries to do it in this manner, the forklift 10 may optionally refuse to respond to remote commands from the new operator, for example, where the forklift is further tied to the operator's identification code. As such, a new operator may be required to initiate a complete forklift actuation sequence, as well as a wireless remote control pairing sequence, in which case, the new operator's operator identification code may be registered by the forklift 10 .

If the prescribed period of time expires, then the pairing information stored in the forklift's memory can be cleared, for example, by erasing an association between the receiver's identification code and the transmitter's identification code. Similarly, when the communications device is removed from the corresponding docking area of ​​a garment and returned to its storage location, for example a charging station, the memory within the communications device corresponding to the pairing information. For example, when the communications device is removed from the garment and charged in a recharger or another

Furthermore, this information can be downloaded from a corresponding commercial company. This configuration can be beneficial, for example, where communication devices are shared among a community of users.

In accordance with additional aspects of the present invention, individual communication devices can be assigned to particular forklift operators as an alternative to having a reserve of available transmitters. For example, suppose the forklift operator deactivates the forklift. In response to deactivation, a timer starts to run. At this time, the pairing information is still stored in memory. After a prescribed interval of time, the Pairing Information is cleared from the forklift's memory. Suppose the forklift operator leaves the communications device attached to the garment for an extended amount of time. After a certain period of inactivity, the communications device may enter a sleep mode where another timer is set, for example for the shutdown mode. During this time, the Pairing Information is stored in memory and the communications device continues to transmit 'ftd ^ / íSiú'

INÍ. / U5Í RIAL confirmation. During power-off mode, the pairing information is saved. However, the communication device stops transmitting the confirmation tone. After a third prescribed period of time expires, the receiver's identification code is erased from the memory of the communications device.

Referring to Figure 13, an example implementation of remote control device 70 comprises a transmitter 1302, a battery 1304, a control structure 1306, and a communication link 1308 between the transmitter 1302 and the control structure 1306. The transmitter 1302 can transmit information in an analog or digital form using any suitable wireless transmission element, including standard or proprietary formats. For example, transmission can be done using existing technologies, such as 802.1 1, 802.16, Bluetooth, short message service (SMS), amplitude shift keying (ASK), digital amplitude modulation (OOK), area network wireless local (WLAN), code division multiple access (CDMA), amplitude modulated (AM), frequency modulated (FM), universal mobile telecommunications system (UMTS), cell phone technology such as global system for mobile communications (GSM), etc. In practice, the way the transmitter 1302 transmits messages should correspond to the format that is recognizable by the receiver.

Corresponding ΡI 102 (Figure 2) on the forklift ^ pgu ^ a; 1). More_s„,^? still, the remote control device 70 may also contain its own receiver for two-way communication with a corresponding forklift 10.

Control structure 1306 contains controls that instruct transmitter 1302 to transmit an appropriate command.

In the illustrated example of Figure 13, there are two controls, implemented as switches or buttons. A first button 1310 corresponds to a travel command, which, if actuated, causes transmitter 1302 to transmit a travel command. If the travel command is properly received by receiver 102, forklift 10 will be controlled to travel forward.

Alternatively, the first button 1310 could comprise a Go button that instructs the forklift 10 to travel for a prescribed time and / or distance, and then enter a brake or controlled coasting. The first button 1310, alternatively, may provide travel as long as the actuation of the first button 1310 is maintained. The control structure 1306 may also optionally include directional and / or directional controls, as described in detail herein.

A second button 1312 corresponds to a stop command, which, if actuated, causes transmitter 1302 to transmit a stop command. If the stop command is properly received by receiver 102, forklift 10 will stop.

Π. 4Γ T ?, Τ

Β ίί 0 «” '· J will control to reach a controlled stop, De., A. Alternatively, second button 1312 may correspond to a coast forward command, which, if properly received by receiver 102 on forklift 10, will cause forklift 10 to coast to a stop.

When either first or second button 1310, 1312 is pressed, transmitter 1302 formats an appropriate message, and transmits the resulting signal to receiver 102. In this regard, the transmitter 1302 can append to the command, a sequence, a control or other Identification Information, a time stamp, a channel indication, or other data necessary for the receiver 102 to discriminate that the remote control device 70 particular on a valid communications device, to authenticate operators, to record data for history or other purposes, etc.

The first and second buttons 1310, 1312 are integrated into a suitable finger garment 1314 which is illustrated including a first finger segment band 1316, a second finger segment band 1318, and a bridge 1320. The first finger segment band 1316 supports the first 1310 button to implement tour commands. Signals from first button 1310 travel along a first signal carrier cable that extends through bridge 1320, across the band of second finger segment 1318, and to communication link 1308, which can comprise a second signal carrier cable

integral with, or coupled to, the first carrier cable⁴# ^ sign.

While communication link 1308 is illustrated as a wired connection, any suitable technology can be used to communicateably link transmitter 1302 to control structure 1306. In addition, Figure 13 illustrates that transmitter 1302 and power source 1304 are worn by the operator around the wrist or arm. However, transmitter 1302 and power source 1304 can be used separately or together anywhere on the body where it is comfortable, practical, or desirable, as dictated by the specific application. For example, as shown, transmitter 1302 and power source 1304 are attached to the operator's wrist or arm using a flexible, adjustable band 1321. Arm band 1321 can be easily removable from transmitter 1302 and power source 1304, such that each operator can use personal or new bands 1321.

By separating transmitter 1302 from control structure 1306 and coupling both via communication link 1308, a single transmitter 1302 can be reused with multiple instances of control structures 1306. As such, for example, operators at different Shifts can maintain their own control structures 1306, for example, by means of finger or hand controls, and simply plugging it into the transmitter 1302 corresponding to the Start of their shift. This also allows the labels of jl ly á 'to be incorporated: L INSTITUTE; ··· &lt;, GCANü / f

Radio Frequency Identification (RFID) with the priiw &amp; ^ j ^^ eáwiT ^ t ^ buttons 1310, 1312, the information of which can subsequently be transmitted to the forklift 10. As such, the forklift 10 can enter the operator, productivity and other relevant information during the operation.

The remote control device 70, therefore, defines a portable control device that is carried by the operator who interacts with the forklift 10. This example remote control device 70 comprises a flexible band 1321 that is supported on the arm or operator's wrist, and finger garment 1314, which is positioned on the operator's index finger such that the first and second buttons 1310, 1312 face the operator's thumb.

The remote control device 70 according to this embodiment minimizes the number and size of the items mounted on the operator's finger / hand, because the control structure

1306 according to this mode it is the only structure mounted on the operator's finger / hand. Therefore, the interference caused by the remote control device 70 with the operator's work functions, such as grabbing, loading, and placing articles, is reduced. Furthermore, while the remote control device 70 according to this mode is especially suitable for high temperature environments, that is, because the operator's sweat is reduced by the components mounted on the finger / hand, the control device remote 70 of

INSTITUTE 3 - 'according to this modality a glove can also be made, so that the use of the remote control device 70 ... is also particularly suitable for cold environments. Furthermore, the remote control device 70 according to this embodiment is designed as a "one size fits all" device, that is, it can accommodate operators with different hand sizes, and can be designed to fit right-handed or left-handed operators.

Referring to Figures 14 and 15, the first and second buttons 1310 and 1312 of the control structure 1306 of the remote control device 70 can be easily reached and operated with the corresponding thumb of the operator, as schematically represented by the directional arrow. 1322. This action requires deliberate, yet easily achievable action on the part of the operator to actuate either the first or the second button 1310, 1312. Furthermore, operational sequences may be required to actuate the first and / or second buttons 1310, 1312 or for the forklift 10 to actuate a particular command, as described herein. For example, a double click in rapid succession, that is, a double click, may be required to transmit a signal or for the forklift 10 to actuate a control.

Referring to Figure 16, the remote control device 70 can be used in such a way that no hand will inconveniently or otherwise interfere with the operator OR_p to use both hands to pick up items. Furthermore, there is no inconvenience, such as requiring large limb movements, difficult-to-reach or otherwise inaccessible controls to move or stop the forklift 10, even when the operator's hands are O_p are currently engaged in a collection operation. As such, the OR operator_pYou can move or stop the forklift 10, even when you are loading large items with both hands.

Referring to Figure 17, the control structure 1306 of a remote control device 70 in accordance with another embodiment of the present invention may include a raised / contoured collar 1330 around each of the first and second buttons 1310, 1312 ( only the first button 1310 is shown in Figure 17). To actuate and / or select one of the first or second buttons 1310, 1312, an operator must press down in the direction of arrow 1332.

With reference to Figure 18, as another alternative embodiment, the first finger segment band 1316 and the second finger segment band 1318 may comprise a fabric or material adjustable, for example, by locks or hooks such as a hook material. and loops sold, for example, under the trademark Velero®, owned by Velero Industries BV of the Netherlands.

Referring to Figures 19A through 19D, yet another exemplary remote control device configuration is illustrated. Remote control device 70 includes a single button 1334. Button 1334 can be programmed to support multiple commands. For example, remote control device 70 can be configured to transmit a stop command if a single actuation of button 1334 is detected. Furthermore, a travel command can be transmitted if a double click or double actuation of the button 1334 is detected within a predetermined period of time. Alternatively, single or multiple instances of the same signal can be transmitted using

1Ν5Τ; ~ Όϊν Κ £ the remote control device 70 based on erf⁵Operator-implemented clicks, where controller 103 on forklift 10 decides which command to actuate, if any, based on the number of signals received and / or current vehicle conditions, as discussed above. Transmitter 1302 and power source 1304 can be worn as an arm strap, as a belt or shirt-attached device, or by other means. Furthermore, the communications link 1308 can be implemented as a relatively thin cable that can be optionally tied onto a retractable spool 1336 as best seen in Figure 1-9D.

Referring to Figure 20, a control structure 1306 is illustrated comprising two sections 1338 and 1340 that hinge around a hinge point 1342, where a spring member (not shown) can be used to provide partial closure. for the two sections 1338 and 1340.

Referring to Figures 21A and 21B, yet another exemplary remote control device 70 is illustrated. As shown the control frame 1306 is clamped over two adjacent fingers of the operator. As such, the 1306 control structure is easily adaptable to right- or left-handed operators without modification. For example, communication link 1308 can be constructed such that it can be "flipped" to the opposite side of control structure 1306 by rotating it 180 degrees, thereby making control structure 1306 suitable for operations.

I?^rright-handed or left-handed. As with the .70 coefficient devices in the previous examples, the controls can be operated with a single gesture of the hand, even when items such as boxes, etc. are being loaded.

As shown, travel button 1310 is positioned adjacent to a downward, spring-loaded, spring-loaded member 1344, which can be manually slid down to expose travel button 1310. As can be seen in Figure 21B, in the illustrated remote control device 70, the cover 1346 for the transmitter 1302 further comprises additional controls. Such buttons can be used to activate the forklift 10 to sound the horn or otherwise provide an audible and / or visual signal, to immediately stop and / or terminate the autoscroll operation, or to perform other desired functions. Alternatively, such controls may implement redundant 1348 travel controls, which may be independently depressed or programmed to require a concomitant actuation to move the forklift 10. In addition, an additional button 1350 is illustrated, the which can be used, for example, as a stop button or a coasting button. As such, cover 1346 can be worn in an easily accessible location, such as attached to a belt, shirt, or pants using clip 1352. Also, communications link 1308 can be retracted into transmitter 1302

Referring to Figures 22A-22B, yet another exemplary remote control device 70 is illustrated. As shown, the transmitter 1302 integrates with the control structure 1306 and, consequently, the need for the communication link 1308 illustrated in the previous examples is avoided. As illustrated, an adjustable strap 1354 is used to support remote control device 70 near the palm / wrist area of ​​an operator.

Referring to Figures 23 and 24, exemplary embodiments are illustrated where the remote control device 70 is carried so as to be supported on the operator's arm, eg, just above the wrist. These remote control devices 70 include 1356 alert elements, such as light-emitting diodes (LEDs), lights, displays, sound generating devices, or other features that provide an audible and / or visual signal about the status of the control device. remote and / or associated forklift 10, for example, when remote control device 70 is in two-way communication with associated forklift 10. These remote control devices 70 are carried by the operator by sliding an appropriate support structure 1358 over the arm, wrist and / or hand. The frame comprises the buttons 1310, 1312, and subsequently alerting elements 1356 of the remote control device 70 can be added to the support frame 1358, or the frame

Referring to Figures 25A through 25C, yet another example remote control device 70 is illustrated. As shown, the controls are thumb-activated. The first and second buttons 1310, 1312 each comprise a first switch component 1310A, 1312A, respectively. Each of the first components of Switch 1310A, 1312A can be actuated by a second component of common switch 1313. In particular, the remote control device 70 includes a first band 1321 that is provided as a finger garment that supports the first component of the switch 1310A of the first button 1310 and the first component of the switch 1312A of the second button 1312 in cavities on the side. of the operator's index finger. The first component of the switch comprises a first cover that includes a cavity and a first contact button 1315 located in the cavity. In a similar manner, the second component of the switch comprises a second cover that includes a cavity and a second contact button 1317 located in the cavity.

To actuate the first button 1310, the common contact 1319 on the operator's thumb is brought into intimate electrical connection with the first contact button 1315, for example, by directing the protrusion of the second switch component 1313 into the recess in the first cover. of the first component of the 1310A switch. When electrical contact is made between the first contact button 1315 and the common contact member 1319, actuation of the corresponding control is achieved. In a similar manner, to actuate the second button 1312, the common contact 1319 on the operator's thumb is brought into intimate electrical connection with the second contact button 1317, for example, by directing the protrusion of the second switch component 1313 to the recess of the second cover of the first component of the switch 1312A. When electrical contact is made between the second contact button 1317 and the common contact member 1319, actuation of the corresponding control is achieved. Although it is disclosed that an intimate electrical connection is required in this embodiment between the common contact 1319 on the thumb and the first and second pot ^ p ^ .cl ^ contact₍1315 and 1317 to actuate the respective controls, proximity structures are also contemplated, wherein the common contact 1319 on the thumb would only have to be brought into very close proximity to the first and second touch buttons 1315 and 1317 to actuate the respective controls. .

Figures 26-28 illustrate a remote control device 70 in accordance with yet another aspect of the invention. Remote control device 70 can be carried such that it is supported on the arm, wrist, and / or hand of the operator. Remote control device 70 in accordance with this aspect of the invention is carried by the operator by sliding a strap 1452 coupled to a support structure 1454 of device 70 over the operator's arm or wrist.

Support structure 1454 contains wireless transmitter / removable power source 1402, 1404, as described herein. Support structure 1454 further comprises alert elements 1456, such as light-emitting diodes (LEDs), lights, visual display screens, sound generating devices, or other features that provide visual and / or audible signals about the status of the device. remote control 70 and / or associated forklift 10, for example, when remote control device 70 is capable of two-way communication with associated forklift 10. Support structure 1454 further comprises connectors 1458 for connection to other functional elements? such as iin -y forklift horn button and / or a brake button, ie, similar to the second button 1312 described in the previous embodiments.

The remote control device 70 further comprises a control structure 1406 comprising a rigid control device 1460 and an elongated and flexible communication link 1408 between the transmitter / power source 1402, 1404 contained in the support structure 1454 and the structure. control 1406. Communications link 1408 in the embodiment shown provides a detachable wired connection between support frame 1454 and control frame 1406 to provide electrical communication between wireless transmitter / power source 1402,

1404 and control device 1460. By separating support structure 1454 from control structure 1406 via communication link 1408, a single power source / transmitter 1402, 1404 can be reused with multiple instances of control structures 1406. As such, for example, operators on different shifts can maintain their own control structures 1406, for example, by means of controls worn on the finger, and simply plug them into the support structure 1454 corresponding to the start of their shift.

Control device 1460 is adapted to be mounted on the operator's hand, for example, one or more fingers of the operator. The control device 1460, which comprises a single

With remote control device 70 in the illustrated position, one-handed operation to access button 1410 is allowed, and button 1410 is actuated to send a signal of the first type comprising a request for travel to the forklift, and can also optionally used to send a signal of a second type comprising a stop or coasting request to the forklift, as described herein.

The button 1410 of the remote control device 70 can be easily reached and operated with the corresponding thumb of the operator. This action requires deliberate, yet easily achievable action on the part of the operator to actuate the button 1410. Furthermore, operational sequences may be required to actuate the button 1410. For example, double pressure in rapid succession, that is, a double click may be required to operate a control, such as a request for travel. Furthermore, a double click may be required if there is no vehicle-related activity, eg, forklift 10 movement, operator-requested wireless commands, etc., or a period of time, eg, 30 seconds, has elapsed. In addition, a double click may be required for the first wireless command requested by an operator after the operator alights from the forklift 10, for example, detected by the sensors of

presence 58 described above.

The remote control device 70 can be used in such a way that neither hand of the forklift operator will inconvenience or otherwise interfere with an operator who is using both hands to pick up items. Furthermore, there is no inconvenience, such as requiring large limb movements, controls that are difficult to reach or otherwise inaccessible, to move or stop the forklift 10, even when the operator's hands are currently engaged in a lifting operation. pickup. As such, the operator can move or stop the forklift 10, even when loading large items, such as boxes, etc. with both hands, using a single simple gesture.

Any of the disclosed configurations for remote control device 70 can be equipped with steering trim controls and / or can be integrated with a forklift steering angle control 10. Steering angle control is typically implemented using a potentiometer, encoder, or other suitable input device, and can be placed in any convenient location on the forklift 10.

When used in combination with additional steering controls, the steering angle control sets a desired orientation for the forklift 10. As an example, an operator aligns the forklift 10 in an aisle parallel to a row of shelves in the operation of a stock. Using feedback from

<img file="MX354755B_D0038.tif" />

¡? O „; / ////.// X'7 angle detection, as described in I presented; t »-Ofienía« ián--^>The forklift 10 can be held parallel to each other as the forklift 10 moves down the aisle. The steering angle control therefore prevents the forklift 10 from drifting and maintains its course. Under this configuration, a request for travel from remote control device 70 causes forklift 10 to travel substantially straight on the orientation defined by steering controller 112.

A system that implements the functionality of the displacement control provided herein may implement additional advanced features to meet performance requirements. For example, transmitters may be equipped with a global stop command that turns off all forklifts 10 within range of the transmitter that are operating under remote control. Accordingly, all receivers can be programmed or otherwise configured to acknowledge the stop command, for example, using a global or common script.

In each of the illustrated example systems, an antenna for the transmitter could be located in a transmitter box, sewn into the garment, for example, integrating the antenna into Sailboat, straps, bands, or other components associated with the transmitter, that is carried by the operator, located in the wiring between the transmitter box and the controls, etc.

Still further, the transmitter can be directional. For

100 yry, τ „

Ivi ri INSTnuTDMV.iCV-O,, - for example, a target can be provided on the rrfba eg as part of receiver 102 (Figure 2) or antenna 66 (Figure 1).

Accordingly, the operator must point the transmitter of the remote control device 70 at the target to cause the control operation, for example, a drive command, to be received by the forklift 10. Alternatively, certain commands may not be directional, where other controls are directional. For example, global arrest (when provided) may not require detection of a target to take effect. On the other hand, a control to initiate a scrolling operation may require the detection of a suitable target. Target detection can be performed, for example, using infrared technologies or other suitable technologies.
