Additional details regarding the remote control device 32 will be discussed in detail below. The vehicle 10 also comprises one or more non-contact obstacle sensors 40, which are provided around the vehicle 10, for example, towards the first end section of the power unit 14, as shown in Figures 1 and 2. 2. The obstacle sensors 40 can be operated in such a way as to define at least one detection zone. For example, at least one detection zone may define an area at least partially ahead of a forward direction of travel of the vehicle 10 when the vehicle 10 is moving in response to a move request received wirelessly from the vehicle. remote control device 32, as will also be described in greater detail herein. Obstacle sensors 40 may comprise any suitable proximity sensing technology, such as ultrasonic sensors, image capture devices, infrared sensors, laser scanner sensors, etc., which are capable of detecting the presence of objects or obstacles, or that are capable of generating signals that can be analyzed in order to detect the presence of objects or obstacles within the previously defined detection zones. In the exemplary embodiment shown in Figures 1 and 2, the vehicle 10 includes a first obstacle detector 42 and a pair of second obstacle detectors 44A and 44B mounted on the control unit. power 14. The first obstacle detector 42 is spaced apart from the second obstacle detectors 44A and 44B along a vertical axis Va of the vehicle 10 defining a vertical direction, that is, the second obstacle detectors 44A and 44B are are located below (closer to the ground than) the first obstacle detector 42, see Figure 1. The second obstacle detectors 44A and 44B are spaced apart from each other along a horizontal axis Ha of the vehicle 10 that defines a horizontal direction, see figure 2. The first obstacle detector 42 may comprise a scanning laser sensor capable of detecting objects, for example, in the first, second and third zones Ζ1, Z2 and Z3 (also referred to herein as scan zones or detection zones). ), wherein the first, second and third zones Ζ1, Z2 and Z3 can comprise flat zones (see Figures 1 and 2). The second zone Z2 may comprise a stop zone, and the first and third zones Z1 and Z3 may comprise the left and right direction bumper zones, such as the stop zone and the left and right direction bumper zones that are described in United States Patent No. 8,452,464, issued May 28, 2013, entitled "STEER CORRECTION FOR A REMOTELY OPERATED MATERIALS HANDLING VEHICLE", the full disclosure of which is incorporated by reference herein. It should be noted that the first obstacle detector 42 may be capable of detecting the objects in zones additional to or less than the three zones Ζ1, Z2 and Z3 that are illustrated. In an exemplary detection zone configuration, any or all of the detection zones may be used as disclosed in United States Patent No. 9,002,581 issued April 7, 2015 and entitled “OBJECT TRACKING AND STEER MANEUVERS FOR MATERIALS HANDLING VEHICLES”, the full disclosure of which is incorporated by reference herein. The second obstacle detectors 44A and 44B may comprise point laser sensors that are capable of detecting objects between one or more of the zones Ζ1, Z2 and Z3 of the first obstacle detector 42 and the vehicle 10, that is, below one or more of the zones Ζ1, Z2 and Z3, as illustrated in figure 1, and / or beyond the zones Ζ1, Z2 and Z3, and are preferably capable of detecting at least the objects by below the second zone Z2. The second obstacle detectors 44A and 44B are thus capable of detecting objects that are located in a non-detection zone DZ of the first obstacle detector 42, see FIG. 1, that is, where the non-detection zone DZ is defined as an area below the zones Ζ1, Z2 and Z3 and is therefore not detected by the first obstacle detector 42. Therefore, the first obstacle detector 42 functions in such a way as to detect objects that are located along the path of travel of the power unit 14 beyond the non-detection zone DZ, while the second obstacle detectors 44A and 44B function in such a way as to detect the objects along the travel path of the power unit 14 in the non-detection zone DZ, which is located just in front of the vehicle 10, as shown in figure 1. Additional sensor configurations and / or detection zones may be used, such as the oncAnn / i ζπζ / β / υ discussed in the various patents and patent applications incorporated by reference herein. The vehicle 10 shown in Figures 1 and 2 further includes a charging station 50 which comprises an additional system component 8 and which is provided for charging a rechargeable power supply of the remote control device 32. describe additional details in connection with the charging station 50. Control system for remote operation of a low level order picking truck Referring to Figure 3, a block diagram illustrates a control arrangement for integrating remote control commands with the vehicle 10. A receiver 102, which may be a Bluetooth Low Energy (BLE) radio ), for example, is provided to receive the commands issued by the remote control device 32. The receiver 102 passes the received control signals to a controller 103, which implements the appropriate response to the received commands and thus may also be referred to herein as a master controller. In this sense, the controller 103 is implemented in hardware and can also run software (including firmware, resident software, microcode, etc.). Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable media having the computer readable program code embodied therein. For example, the vehicle 10 may include a memory that stores the computer program product, which, when implemented by a controller processor 103, implements the steering correction, as described in more detail in This document. Therefore, the controller 103 may define, at least in part, a data processing system suitable for storing and / or executing the program code and may include at least one processor directly or indirectly coupled to the memory elements, for example, via a system bus or other suitable connection. Memory elements may include local memory used during the actual execution of the program code, memory that is integrated into a microcontroller, or an application-specific integrated circuit (ASIC), a gate array programmable or other reconfigurable processing device, etc. The response implemented by the controller 103 in response to commands received wirelessly, for example, through a wireless transmitter 178 of the remote control device 32 (discussed later) and sent to the receiver 102 in the vehicle 10 , can comprise one or more actions, or inaction, depending on the logic being implemented. Positive actions may include controlling, adjusting or otherwise altering one or more components of the vehicle 10. The controller 103 may also receive the information from other inputs 104, for example from sources such as presence sensors 22, obstacle sensors 40, switches, load sensors, encoders, and other devices or features available to the vehicle 10, in order to determine appropriate action in response to commands received from the vehicle. remote control device 32. Sensors 22, 40, etc. can be coupled to controller 103 oncBnn / i znz / B / v via inputs 104 or via a suitable truck network such as a control area network (CAN) bus 110 . In an exemplary arrangement, remote control device 32 is operative to wirelessly transmit a control signal representing a signal of a first type, such as a drive command, to receiver 102 in vehicle 10. The move command is also known herein as a move signal, move request or go signal. The drive request is used to initiate a request to the vehicle 10 to drive, for example, for as long as the drive signal is received by the receiver 102 and / or sent by the remote control device 32, for an amount previously determined, for example, to cause the vehicle 10 to advance or jog in a first direction for a limited travel distance, or for a limited time. The first direction can be defined, for example, by the movement of the vehicle 10 in a direction of the power unit 14 first, that is, the forks 16 towards the rear. Alternatively, however, other directions of travel can be defined. Furthermore, the vehicle 10 can be controlled to move in a generally straight direction or along a predetermined heading. In a corresponding manner, the limited travel distance can be specified by means of an approximate travel distance, a travel time or another measure. Therefore, a signal of a first type received by receiver 102 is communicated to controller 103. If controller 103 determines that the offset signal is a valid offset signal and that the current vehicle conditions are appropriate (such as explained in more detail in US Patent No. 9,082,293, which is already incorporated by reference herein), controller 103 signals the appropriate vehicle control arrangement 10 to advance and then stopping the vehicle 10. Stopping the vehicle 10 can be implemented, for example, either by allowing the vehicle 10 to slow to a stop or by initiating a braking operation to cause the vehicle 10 to slow to a stop. As an example, the controller 103 may be communicatively coupled to a traction control system, which is illustrated as a traction motor controller 106 of the vehicle 10. The traction motor controller 106 couples to a traction motor 107 that drives at least one steering wheel 108 of vehicle 10. Controller 103 may communicate with traction motor controller 106 in order to speed up, slow down, adjust and / or otherwise limit the speed of the vehicle 10 in response to receiving an offset request from the remote control device 32. The controller 103 may also be coupled in a communicable manner to a steering controller 112, which is coupled with a steering motor. 114 that directs at least one steering wheel 108 of the vehicle 10. In this regard, the vehicle 10 may be controlled by the controller 103 to move along a predicted path or to maintain a predicted direction in response to receiving inputs. a displacement request from the remote control device 32. As yet another illustrative example, controller 103 may be coupled in a communicable oncAnn / i znz / B / v manner with a braking controller 116 that controls the brakes of the vehicle 117 in order to slow, stop, or otherwise control the speed of the vehicle 10 in response to receiving an offset request from the remote control device 32. Still further, the controller 103 may be coupled in a communicable manner with other features of the vehicle, such as main contacts 118 and / or other outputs 119 associated with the vehicle 10, where appropriate, in order to implement the desired actions in response to the implementation of the remote drive functionality. In accordance with various aspects of the present invention, controller 103 may communicate with receiver 102 and drive motor controller 106 in order to operate vehicle 10 under remote control in response to receiving drive commands. drive from the associated remote control device 32. Still further, the controller 103 can be configured in such a way as to perform various actions if the vehicle 10 moves under the remote control in response to a drive request and a drive is detected. an obstacle in one or more of the detection zones Ζ1, Z2 and Z3. In this regard, when controller 103 receives an offset signal from remote control device 32, controller 103 may take into account any number of factors in order to determine whether to act on the received offset signal in order to to initiate and / or maintain the movement of the vehicle 10. In a corresponding manner, if vehicle 10 moves in response to a command received by remote control device 32, controller 103 may dynamically alter, control, adjust, or otherwise affect remote control operation, for example, by stopping the vehicle 10, by changing the steering angle of the vehicle 10, or by taking other actions. Therefore, particular characteristics of the vehicle, the state or condition of one or more characteristics of the vehicle, the environment of the vehicle, etc., can influence the way in which the controller 103 responds to the requests of displacement from the remote control device 32. The controller 103 may refuse to acknowledge a received shift request depending on predetermined conditions, eg, relating to environmental or operational factors. For example, controller 103 may ignore an otherwise valid offset request based on information obtained from one or more of sensors 22, 40. As an illustration, in accordance with various aspects of the present invention, controller 103 may optionally consider factors such as whether an operator is in vehicle 10 when determining whether to respond to a drive command from remote control device 32. As noted in the preceding paragraphs, vehicle 10 may comprise of at least one presence sensor 22 to detect whether an operator is positioned in the vehicle 10. In this regard, the controller 103 can be further configured in such a way as to respond to a move request in order to operate the vehicle 10 under remote control when the presence sensors 22 designate that there is no operator in the vehicle 10. Therefore, in this implementation, the vehicle 10 cannot be operated in response to wireless commands from the remote control device 32 a unless the operator is physically outside of the vehicle 10. Similarly, if the oncRnn / ι znz / B / v obstacle sensors 40 detect that an object, including the operator, is adjacent and / or close to the vehicle 10, the operator controller 103 may refuse to acknowledge a hover request from remote control device 32. Therefore, in an example implementation, an operator must be located within a limited range of vehicle 10, eg, close enough to the vehicle 10, to be in wireless communication range (which may be limited in order to establish a maximum distance from the operator to the vehicle 10). Alternatively, other arrangements may be implemented. Controller 103 may also or alternatively implement any number of other reasonable conditions, factors, parameters, or other considerations in order to interpret and take action in response to signals received from transmitter 178. Other example factors are set forth. in greater detail in the United States of America Provisional Patent Application with Serial Number 60 / 825,688, entitled “SYSTEMS AND METHODS OF REMOTELY CONTROLLING A MATERIALS HANDLING VEHICLE; in US Patent Application Serial Number 11 / 855,310, entitled "SYSTEMS AND METHODS OF REMOTELY CONTROLLING A MATERIALS HANDLING VEHICLE" now US Patent No. 9,082,293; in the United States Patent Application with Trademark Number 11 / 855,324, entitled "SYSTEMS AND METHODS OF REMOTELY CONTROLLING A MATERIALS HANDLING VEHICLE" now United States Patent No. 8,072,309; in the United States of America Provisional Patent Application with Serial Number 61 / 222,632, entitled “APPARATUS FOR REMOTELY CONTROLLING A MATERIALS HANDLING VEHICLE; in US Patent Application Serial Number 12 / 631,007, entitled "MULTIPLE ZONE SENSING FOR MATERIALS HANDLING VEHICLES" now US Patent No. 9,645,968; and in the United States of America Provisional Patent Application with Serial Number 61 / 119,952, entitled “MULTIPLE ZONE SENSING FOR REMOTELY CONTROLLED MATERIALS HANDLING VEHICLES; the disclosures of which are each incorporated by reference herein. After acknowledgment of an offset request, the controller 103 interacts with the traction motor controller 106, eg, in a direct or indirect manner, eg via a bus (bus), such as the CAN bus. 110, if used, to move the vehicle 10 forward. Depending on the particular implementation, the controller 103 may interface with the traction motor controller 106 and, optionally, the steering controller 112, in order to move the vehicle forward. vehicle 10 for as long as a drive control signal is received. Alternatively, controller 103 may interface with traction motor controller 106 and, optionally, steering controller 112, in order to move vehicle 10 forward for a period of time or for a distance. previously determined in response to sensing and sustained actuation of a drive control in the remote control device 32. Still further, the controller 103 can be configured in such a way as to time out and stop the drive of the vehicle. 10 based on a predetermined event, such as oncRnn / i znz / E / v exceeding a predetermined period of time or travel distance, regardless of detection of sustained actuation of a corresponding control on the control device remote 32. The remote control device 32 may also be operative to transmit a signal of a second type, such as a stop signal, which designates that the vehicle 10 should brake and / or otherwise come to a standstill. The signal of a second type can also be involved, for example, after a drive command is implemented, for example, after the vehicle 10 has driven a predetermined distance, has driven a predetermined time , etc., under the remote control, in response to the move command. If controller 103 determines that a wirelessly received signal is a stop signal, controller 103 sends a signal to traction motor controller 106, braking controller 116, and / or another truck component to cause the truck to stop. vehicle 10 comes to a stop. As an alternative to a stop signal, the signal of the second type may comprise a coast-down signal or a controlled deceleration signal designating that the vehicle 10 should coast-down, eventually decelerating to a stop. The time it takes to bring the vehicle 10 to a complete stop can vary, depending, for example, on the intended application, environmental conditions, the capabilities of the particular vehicle 10, the load on the vehicle 10, and of other similar factors. For example, after an appropriate jogging motion is completed, it may be desirable to allow the vehicle 10 to roll for a certain distance before coming to a rest so that the vehicle 10 comes to a slow stop. This can be accomplished through the use of regenerative braking in order to slow the vehicle 10 down to a stop. Alternatively, a braking operation may be applied after a predetermined delay time to give a predetermined range of additional travel to the vehicle 10 after initiation of the stopping operation. It may also be desirable to bring the vehicle 10 to a relatively quicker stop, for example, if an object is detected in the path of travel of the vehicle 10 or if an immediate stop is desired after a successful jog operation. For example, controller 103 may apply a predetermined torque to the braking operation. Under such conditions, the controller 103 may instruct the braking controller 116 to apply the brakes 117 in order to stop the vehicle 10. Also shown in Figure 3 is the in-vehicle charging station 50 that can communicate with the controller 103. As will be explained in more detail below, the charging station 50 can be used to charge a power supply from rechargeable power 180 of the wireless remote control device 32. The charging station 50 can be located on the side of the vehicle 10, for example, next to the operator station 20 near the manual driving controls of the vehicle 10, as as shown in figures 1 and 2, or on a side panel of the power unit 14. A pairing system 34 can use a near range system to communicate wirelessly with a compatible near range system in the wireless oncRnn / i ζπζ / β / υ remote control device 32. Through the use of the pairing system 34, a vehicle 10 and wireless remote control device 32 may be paired in such a way that a vehicle 10 transmits and receives messages only from its paired wireless remote control device 32. In addition to, or as an alternative to, close range or other types of wireless communications, such as Near Field Communication (NFC), the pairing system 34 may also use physical contacts that allow electrical communication between the remote control device 32 and the vehicle 10, at least for the initial pairing procedure. For example, the electrical contacts of the charging station 50 used to charge the remote control device 32 could be used to pair the vehicle 10 with the remote control device 32, as will be described in more detail herein. The pairing system 34 includes the components that physically implement the communication method (eg, Bluetooth, NFC, BLE, Wi-Fi, etc.) that is used to send the messages and includes the components that exchange information via the programming in an agreed protocol to establish and maintain a pairing. Therefore, the pairing system 34 includes a device that can execute the programmable instructions to implement a predetermined algorithm and protocol to perform the pairing operations. In figure 3, the charging station 50, the receiver 102 and the pairing system 34 are represented as different functional blocks. However, a person of ordinary skill will recognize that two or more of these components can be combined into a single element in order to provide a multifunctional device. System As noted in the preceding paragraphs, the vehicle 10 (which includes the charging station 50) and the remote control device 32 form the system 8 according to one aspect of the present invention. Now the remote control device 32 and the charging station 50 will be described in turn. Referring to Figures 4-8, the remote control device 32 according to this embodiment is a finger-mounted device, although the remote control device 32 could take other forms, such as a glove-mounted device, a wrist-mounted device, a lanyard-mounted device, etc. The remote control device 32 can be mounted on one finger, two fingers, or more than two fingers of the operator. The remote control device 32 shown in Figures 4-8 comprises a rigid polymeric base 172 (see Figure 6) and a rigid upper polymeric housing 174. The base 172 and upper housing 174 mate with each other through in any suitable manner and define an internal area 176 for receiving the internal components of the remote control device 32, including a wireless communication system 456 including a wireless transmitter 178, such as the wireless transmitter 178 described above with reference to the 3, and a rechargeable power supply 180. In an exemplary embodiment, the wireless transmitter 178 comprises a model BGM121 manufactured by SiLabs. It should be noted that the terms transmitter and receiver as used in this document are intended to refer to a device capable of having one-way communication, ie oncAnn / i znz / B / v that is, the device only transmits or receives the signals, or a device capable of two-way communication, such as a transceiver, that transmits and receives the signals. The rechargeable power supply 180 can be a super capacitor, a high-capacity battery, etc. For example, you can use an AVX super capacitor, model SCCR20 E335PRB, which has a nominal voltage of 3 V and a capacitance of 3.3 F. The rechargeable power supply 180 is small enough to fit inside the internal area 176 while also having sufficient capacity on a substantially full charge to produce a usage period for the remote control device 32 of at least two hours, at least four hours, at least eight hours, or more. A period of use of up to eight hours may be preferable to correspond to an eight hour work shift for an operator. A super capacitor (also referred to as a supercap or ultra capacitor) is a high capacity capacitor with much higher capacitance values ​​than other capacitors, but generally with lower voltage limits that bridge the gap between electrolytic capacitors. and rechargeable batteries. They typically store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerate many more charge-discharge cycles than batteries. rechargeable. Because super capacitors can be used in applications that require many rapid charge and discharge cycles, some modes of the remote control device 32 may include a super capacitor as the rechargeable power supply 180. In the modes of With the present invention, the current that is supplied to the super capacitor can be limited to about 2 A, and charging to a full charge can be carried out in about 2 seconds or less. Regardless of the specific type of rechargeable power supply 180 that is used, embodiments of the present invention contemplate recharging the rechargeable power supply 180 to a desired amount, such as to a fully charged state, or to a state of charge less than a substantially full state of charge (as will be discussed in detail herein) via the charging station 50 within a desired charging period. The power supplied to the rechargeable power supply 180 by the charging station 50 can be varied according to the capacity of the rechargeable power supply 180, the amount of charge desired, and / or the charging period desired. , as will be discussed in greater detail in this document. Referring to Figure 6, the remote control device 32 further comprises holding structure 188 for securing the remote control device 32 to one or more fingers of the operator's hand. The fastening structure 188 in the embodiment shown in Figure 6 comprises a fastening strap 190 including, for example, hook-and-loop tape fasteners 191 for securing the fastening strap 190 to a single finger, for example. , the index finger, of the operator. Remote control device 32 is provided with first and second slots 192A and 192B that are located at opposite ends of remote control device 32 to receive tether strap 190. The tether strap 190 shown in Figure 6 defines a first receiving area of ​​the QncRnn / ι znz / B / v finger 194 to receive the single finger Of (see Figures 1 and 2) from an operator using the remote control device 32. Right and left versions of the remote control device 32 can be created The remote control device 32 is releasably held on the operator's index finger via tether strap 190. In an exemplary embodiment, a first end 190A of tether strap 190 is threaded through the first slot 192A and a second end 190B of the tether strap 190 is threaded through the second slot 192B. The first end 190A of the tether strap 190 can be permanently attached to the rigid base 172, for example, by means of stitching or gluing, while the second end 190B of the tether strap 190 can be inserted in a releasably through the second slot 192B and is folded back in such a manner that the hook-and-loop fasteners 191 engage together to secure the tether strap 190 to the operator's finger. The holding strap 190 can be adjusted in such a way as to accommodate fingers of different sizes or in such a way that the remote control device 32 can be worn over a glove (not shown). It should be noted that other types of tether straps 190 can be used. The remote control device 32 further comprises at least one control, which is represented in figures 4 to 8 as the first, second and third controls 196 A to C. The controls 196 A to C each comprise a button 197 A to C, and a two-state switch 198 A to C which is located below the corresponding button 197 A to C. The switches 198 A to C communicatively couple to the wireless communication system 456 such that the actuation of each of the controls 196 A to C causes the wireless transmitter 178 to wirelessly transmit a respective request to the vehicle 10. In the example remote control device 32, which is depicted in Figures 4 to 8: the first control 196A comprises a drive button 197A which, when depressed, causes wireless transmitter 178 to wirelessly transmit a request for vehicle 10 to drive across a floor surface; Second control 196B comprises a horn button 197B which, when pressed, causes wireless transmitter 178 to wirelessly transmit a request for vehicle 10 to sound a horn or audible alarm; and third control 196C comprises a brake button 197C which, when depressed, causes wireless transmitter 178 to wirelessly transmit a request for the vehicle to stop (if it is moving under wireless control), and optionally, turn off. The remote control device 32 is compact, and substantially all of the remote control device 32 can be mounted and positioned directly on the operator's index finger. Therefore, the interference of the operator carrying out the work tasks caused through the use of the remote control device 32 is minimal or non-existent. The remote control device 32 is durable and long lasting because the rigid base 172 and upper housing 174 are preferably formed from a durable and rigid polymeric material, such as acrylonitrile butadiene styrene (ABS). in English), polycarbonate or nylon. The rigid base 172 and upper shell 174 define a durable rigid and generally inflexible structure. An operator can easily actuate the jog button 197A manually through QncRnn / ι znz / B / v of his thumb in order to cause the wireless transmitter 178 to wirelessly transmit at least one signal of a first type designating a request or command to move to the vehicle 10. It is contemplated that the drive request may result in the vehicle 10 being driven for as long as the operator holds down the drive button 197A, or for a predetermined distance or a predetermined amount of time. The horn button 197B and the brake button 197C may be actuated by the operator's opposite hand, for example. As shown in Figures 4 and 5, the remote control device 32 further comprises one or more load contacts 210, where it is noted that additional or less load contacts 210 may be used than the four shown, for example, they can use one load contact 210 or two or more load contacts 210. In addition, the remote control device 32 further includes one or more sensors in the form of the first presence contacts 212, which are illustrated in Figures 4 and 5, as a single first presence contact 212 located intermediate the four load contacts 210. The load contact and the first presence contacts 210 and 212 can be arranged within openings 214 formed in an external surface of the upper case. 174 of the remote control device 32. The upper parts of the load contact and the first presence contacts 210 and 212 can be placed below the external surface of the upper case, that is, the load contact and the first presence contacts. presence 210 and 212 can be embossed within the openings 214, which can prevent damage to the charging contact and the first presence contacts 210 and 212 due to accidental contact. It should be noted that other configurations for the number, orientation, and placement of the charging contacts 210 and the first presence contacts 212 could be used without departing from the scope and spirit of the invention. In some embodiments, charging contacts 210 are spliced ​​or mated to elements, for example, electrical contacts or charging elements 220 of in-vehicle charging station 50 (discussed later), and the first presence contact 212 is spliced ​​or coupled with a complementary second sensor in the form of a second presence contact 222, such as a switch, pogo pin, or push pin, for example, from the charging station in vehicle 50, as shown in Figures 8A and 8B and as will be described in more detail herein. It should be noted that one or more of the load contacts 210 and the corresponding load elements 220 may be provided for redundancy. In one example, the four load contacts 210 illustrated in Figures 4-7 and the four load elements 220 illustrated in Figures 12-14 could be configured as two redundant contact / element pairs 210 / 220, wherein charging of the rechargeable power supply 180 (as discussed below) is enabled as long as one charging contact 210 of each pair is connected to and in electrical communication with its corresponding charging element 220. Embodiments of the present invention also contemplate non-contact, or induction, charging, in which the rechargeable power supply 180 of the remote control device 32 can be charged by the remote control device 32 that is in close proximity or on the surface of an oncAnn / i znz / B / v compatible induction charging station (not shown). Said induction charging station can be located, for example, in a drive or steering control of the vehicle 10, in such a way that the rechargeable power supply 180 can be charged while the operator is manually driving the vehicle 10. from operator station 20. Figures 9 and 10 illustrate another example remote control device 32, where like reference numerals correspond to components similar to those listed above for Figures 4 to 8. The remote control device 32 according to This embodiment is intended as a two-finger design, that is, the grip structure 188 in the embodiment shown in Figures 9 and 10 comprises a grip strap 190 defining the first and second finger receiving areas 194 and 195 for receiving the index and middle fingers of an operator using the remote control device 32. The remote control device 32 according to Figures 9 and 10 includes two charging contacts 210 instead of the four charging contacts 210 in the remote control device 32 of Figures 4 to 8. The remaining components of the remote control device 32 of Figures 9 and 10 may be broadly the same as those of the remote control device 32 of Figures 4 to 8 and therefore, they will not be described in detail herein. Figure 11 provides a functional block level diagram of a vehicle charging station 50 in accordance with the principles of the present invention, wherein the pairing system 34 is incorporated into the charging station 50. As explained In more detail below, charging station 50 may include receiver 102, for example, a Bluetooth Low Energy (BLE) radio 402 that can communicate with vehicle controller 103. Although not shown, communication may be via the vehicle's CAN bus and therefore the charging station 50 may include a CAN bus interface. The charging station 50 may also include one or more light emitting diodes (LEDs) 404 or other visual indicators that help convey information to an operator. For example, one LED may be used to indicate that a remote control device 32 is currently docked with the charging station 50. Other LEDs may indicate a current state of charge of the control device's rechargeable power supply 180. remote. A current limiter 406 or other protection circuitry may be provided that can help ensure that a remote control device 32 is recharged safely, because the current limiter 406 allows the voltage from the power source to vehicle power supply is provided to the charging elements 220 of the charging station 50 in order to charge the rechargeable power supply 180 of the remote control device. These charging elements 220 interface with the charging contacts 210 of the remote control device 32 and provide the electrical connection between the vehicle's power source and the rechargeable power source 180 of the remote control device 32. second presence contact 222 connects to first presence contact 212 to detect when a remote control device 32 is physically connected to charging station 50 in such a way that charging contacts 210 connect to charging elements 220 According to some embodiments, after the second presence contact 222 is mated with the first presence contact 212, the pairing process onoRnn / i 7f\7iw is started. It should be noted that the first and second presence contacts 212 and 222 can respectively be provided either in the remote control device 32 or in the charging station 50. That is, while the second presence contact 222 is illustrated in the charging station 50 and the first presence contact 212 in the remote control device 32, the second presence contact 222 could be located in the remote control device 32 and the first presence contact 212 could be located in the station charge 50. The relationship between the second presence contact 222 and the charging elements 220 is such that the charging contacts 210 of the remote control device 32 and the charging elements 220 of the charging station 50 are in contact with each other before that the second presence contact 222 connects with the first presence contact 212 when a charging procedure is being initiated; see figure 8A, which shows that the height of the second presence contact 222 is less than the height of the charging elements 220, the heights measured with respect to the upper surfaces of the element casings 220A and a casing of the second contact contact 222A from which the respective charging elements 220 and the second presence contact 222 extend. The power supply from the charging station 50 to the remote control device 32 via the charging elements / charging contacts 220 / 210 only starts after the second presence contact 222 connects with the first presence contact 212. During a charging procedure, the charging contacts 210 of the remote control device 32 connect with the charging elements 220 of the charging station 50, and the second presence contact 222 is connected to the first presence contact 212, thereby enabling power supply from the charging station 50 to the remote control device 32 at via charging elements / charging contacts 220 / 210, see figure 8B. After the rechargeable power supply 180 is charged to the desired amount, for example, fully charged or charged to a desired amount less than fully charged, as described herein, the power is cut off. power supply from the charging station 50 to the remote control device 32 via the charging elements / charging contacts 220 / 210. In the event that the remote control device 32 is removed from the charging station 50 before the rechargeable power supply 180 is charged to the desired amount, as the remote control device 32 is removed from the charging station 50, the second presence contact 222 is disconnected from the first presence contact 212 before the charging elements 220 are disconnected from the charging contacts 210. The power supply from the charging station 50 to the power source The rechargeable power supply 180 of the remote control device 32 via the charging elements / charging contacts 220 / 210 is cut off when the second presence contact 222 is disconnected from the first presence contact 212. This arrangement is intended to prevent the formation of an arc between the load elements 220 and the load contacts 210. The use of the first presence contact 212 and the second presence contact 222 in the form of a Rogo pin provides the following advantages: precise control of the relative heights of the second presence contact 222 and the load elements 220; a small footprint, a good seal, eg, oncAnn / i znz / B / v to prevent moisture from entering the housing of the second occupancy contact 222A from around the second occupancy contact 222; and allows differentiation to be made between the first presence contact 212 and a foreign object, such as a piece of metal, which would prevent electrical current from flowing to such a foreign object if it were to come into contact with the second presence contact 222 and one or more of the load elements 220. As an alternative to the presence contacts 212 and 222 which are used to initiate the supply of power from the charging station 50 to the remote control device 32, a separate switch may be present which the operator activates in order to initiate a load operation. In a specific embodiment using induction charging, such a switch may be incorporated into the steering control of the vehicle, in such a way that operator holding of the steering control is detected and charging is then enabled. The controls 414 for providing the control signals to operate the LEDs 404 can come from a number of sources. While the remote control device 32 is operated within the range of the charging station 50, the controller 103 can receive the information about the state of charge of the rechargeable power supply 180 and control the LED display 404 with in order to transmit this information through the use of a CAN bus interface, for example. When the remote control device 32 is docked with the charging station 50, the LEDs 404 can be used to convey: a) that a remote control device 32 is physically connected to the charging station 50, b) that there is a device remote control 32 currently paired with the vehicle controller 103, c) the progress or charging status of a current charging operation, and / or d) the charging status of the rechargeable power supply 180. The charging information items c) and d) can be sent to the charging station 50 by means of the remote control device 32, for example, via a Bluetooth low energy (BLE) connection, and this BLE connection will be discussed in more detail later. According to one aspect, because the pairing and charging processes are carried out very quickly, the progress or charging status of a current charging operation may not be displayed by the LEDs 404. The control device The remote 32 can store its charging profile and then send the charging profile to the charging station 50, for example via the BLE connection, after the remote control device 32 is removed from the charging station 50, wherein the charge profile can be evaluated, for example, by controller 103, to determine if a proper charge of rechargeable power supply 180 has occurred. Second presence contact 222 can also send the control signals to the controls 414, which indicate whether the charging contacts 210 of the remote control device 32 are correctly mated with the corresponding charging elements 220 of the charging station 50. Figures 12 through 14 illustrate other features of the charging station 50 that is located in the vehicle 10. The charging station 50 may include one or more physical protrusions or guide structures 420 that help guide the remote control device 32. in the correct alignment in such a way that the charging elements 220 of the station are aligned with the charging contacts 210 of the remote control device 32, that is, the guide structures 420 align the remote control device 32 in the QncRnn / ι znz / B / v proper orientation for charging the rechargeable power supply 180. In Fig. 12, a single guide frame 420 is shown including a plurality of guide surfaces. Guide structures 420 can be positioned around the location of load elements 220 and can be shaped or angled in such a way that remote control device 32 is physically guided to correct alignment as the operator places the remote control device 32 in the charging station 50. In Figure 13, the LEDs 404 include a visual indicator 424 indicating that a remote control device 32 is connected to the charging station 50. The visual indicator 424 may illuminate, blink, or fill in progressively as a first color in order to indicate that the remote control device 32 is connected to the charging station 50, and as a second color or a fully filled first color in order to indicate that the remote control device 32 has been paired with the vehicle controller 103, that is, the visual indicator 424 can use either the second color or the fully filled first color to serve as a pairing indicator confirming the establishment of communication between the remote control device 32 and the vehicle 10. Furthermore, according to a As an optional aspect of the invention, LEDs 404 may flash, illuminate as a second color, or provide some other visual indication after the establishment of communication between remote control device 32 and vehicle 10 as a signal for the operator to take action. perform an action such as a test to confirm that the remote control device 32 is functional and can communicate with the vehicle 10, for example, such as pressing the horn button 197B and the brake button 197C simultaneously. It is understood that separate indicators may be used for the purpose of indicating that a remote control device 32 is connected to charging station 50 and to indicate that remote control device 32 has been paired with vehicle 10, rather than a single indicator that can serve both functions. LEDs 404 may further serve as an indicator to identify the progress of a charging operation when remote control device 32 is connected. When remote control device 32 is not connected to charging station 50, LEDs 404 may serve as an indicator to indicate the current state of charge of the rechargeable power supply 180 of the remote control device 32. In this way, the LEDs 404 can indicate the state of charge of the rechargeable power supply 180 both when charging the rechargeable power supply 180 in the charging station 50 as well as during the use of the remote control device 32, that is, while the operator is using the remote control device 32 in order to help carry carry out work operations. In an exemplary embodiment, the LEDs 404 may comprise an array of lights, each light representing a state of charge level of the rechargeable power supply 180. An example location of the second presence contact 222 within the charging station 50 is shown in Figures 12 and 14. It is noted that the remote control device 32 illustrated in Figures 12 through 14 is the mode for 4 to 7. It is also noted that the charge contacts 210 and the first presence contact 212 of the modalities for a single finger and for oncRnn / ι znz / B / v two fingers could be arranged in a such as to reflect each other. Therefore, the same charging station 50 could be used for both single-finger and two-finger remote control device instances 32 . The charging station 50 can be located in various places in the vehicle 10. Its location must be such that it does not interfere with the normal operation of the vehicle 10, but where it is accessible and convenient for the operator. In some embodiments, the charging station 50 is located in the operator station 20 (see Figures 1 and 2, where the charging station 50 is located in the operator station 20, but is also accessible from the outside of vehicle 10), on a surface on one side of vehicle 10, or, for the induction charging mode, within the steering control of vehicle 10. The charging station 50 may include a voltage regulator (not shown) that transforms the power from the vehicle 10 received by the charging station 50 to a regulated direct current (DC) voltage signal. selected based on the charging characteristics of the rechargeable power supply 180. For example, in an embodiment in which the rechargeable power supply 180 is an AVX super capacitor as described in the preceding paragraphs or a device equivalent, a supply voltage of 3 V DC (1 percent) could be provided to the current limiter 406. It is noted that the remote control device 32 is described herein as one that has an exemplary configuration and can be structurally modified without departing from the spirit and scope of the invention. For example, one or more components of the remote control device 32 may be combined into an integral component, or the components may be substituted with alternative components serving a similar or identical purpose. In one embodiment, charging of the rechargeable power supply 180 via the charging station 50 is provided when one or more charging contacts 210 connect to a corresponding charging element 220 of the charging station 50. In In some embodiments, at least two load contacts 210 or at least four load contacts 210 and corresponding load elements 220 are present. In some embodiments, one or more pairs of load contacts 210 are provided, in which for at least one charging contact 210 of each pair must be connected to a corresponding charging element 220 for charging to occur. As described in the preceding paragraphs, at least one of the remote control device 32 and the charging station 50 may include a second presence contact 222, such as a switch, for example. The second presence contact 222 detects whether or not the at least one charging contact 210 is correctly connected to the corresponding at least one charging element 220 for charging the rechargeable power supply 180, wherein, if detected a correct connection, the power transfer to the rechargeable power supply 180 is enabled by means of the charging station 50, and if a correct connection is not detected, the power transfer to the rechargeable power supply is not enabled. rechargeable power 180 via charging station 50. Furthermore, the arrangement of the remote control device 32 and the charging station 50 is configured oncRnn / i znz / B / v in such a way that the second presence contact 222 indicates the removal of the remote control device 32 from charging station 50, which causes power transfer to rechargeable power supply 180 from charging station 50 to stop before the at least one charging contact 210 is disconnected from the at least one a corresponding charging element 220. Therefore, power transfer from the charging station 50 to the rechargeable power supply 180 stops before the at least one charging contact 210 is disconnected from the at least a corresponding charging element 220. Therefore, the transfer of power from the charging station 50 to the rechargeable power supply 180 is stopped, before the at least one charging contact 210 of the at least one is disconnected. minus a corresponding load element 220. This can be done, for example, by setting the heights of the load elements 220 and the second presence contact 222, as shown in Figure 8A, where the charging elements 220 are pushed down into the respective element housings 220A before the second presence contact 222 connects with the first presence contact 212, because the remote control device 32 is inserted into the charging station fifty. Figure 15 is a block-level functional diagram of the portions 450 of the remote control device 32 that relate to recharging the rechargeable power supply 180. The other parts of the remote control device 32, such as, for example, those related to mechanical actuators are not shown in Figure 15. As indicated in the previous paragraphs, the remote control device 32 may include one or more load contacts 210 that are configured in such a way as to connect with a corresponding load element. In some embodiments, the charging elements may be the charging elements 220 of the charging station 50. In other embodiments, the charging elements may be those of an adapter that connects to a power source to recharge the source. rechargeable power supply 180. Remote control device 32 may include protection circuitry 452 that limits electrical parameters, such as voltage and / or current, to fall within expected operating ranges. The charge controller and disconnect circuit 454 may monitor the voltage being received from the protection circuit 452, as well as may monitor the current state of charge of the rechargeable power supply 180 in order to determine when charging of the rechargeable power supply 180 must be stopped. For example, according to an exemplary embodiment, when the charge in the rechargeable power supply 180 reaches 3 V, the charge controller and circuit disconnect switch 454 can operate to stop an additional load. The charge controller and disconnect circuit 454 may include temperature sensing capabilities or may be connected to a temperature sensor in such a way that the rechargeable power supply 180 can be charged (or discharged) up to different charge levels. In some embodiments, the rechargeable power supply 180 discharges to a high temperature state of charge, eg, a less than fully charged state, if a sensed temperature is determined to be above a set point temperature. previously determined. In an exemplary aspect of the invention, the detected temperature oncRnn / ι znz / B / v is room temperature. In an alternative aspect, the detected temperature is a battery temperature. In some embodiments, the rechargeable power supply 180 is charged in the charging station 50 to a predetermined charge level below a 100 percent charge level if a sensed temperature is determined to be above a specified temperature. previously determined threshold. This can help prevent damage to or degradation of the rechargeable power supply 180. As shown in Figure 15, the remote control device 32 can include the wireless communication system 456, such as, for example, a BLE radio that can communicate with the BLE radio 402 of the charging station 50 through through a BLE connection. The wireless communication system 456 and / or the BLE radio 402 of the charging station 50 can be configured, for example, in such a way as to enter a low power mode when the remote control device 32 is being paired. with the vehicle 10 and / or when the rechargeable power supply 180 of the remote control device 32 is being charged at the charging station 50, for example, in order to ensure that only one remote control device 32 that is within a minimum distance, for example, within 12.7 cm (five inches) or within 7.62 cm (three inches) corresponding to the signal strength of the communications received from the remote control device 32, from the charging station 50, is recognized as the remote control device 32 with which it is to be paired. Furthermore, if the BLE radio 402 of the charging station 50 were to identify two or more remote control devices 32 available for pairing and could not determine the correct one for pairing, the charging station 50 might not pair with none of the 32 remote control devices available and may require the operator to repeat the pairing process. Association or pairing of a remote control device with a vehicle Figures 16 to 18 illustrate the details of example pairing processes in accordance with some aspects of the invention. The remote control device 32 and vehicle 10 described in the preceding paragraphs will be used in the description of the pairing processes of Figures 16-18, but it is understood that other configurations or styles of remote control device could be paired together. remote and vehicle control according to the invention. Referring to Figure 16, method 500 begins when the vehicle operator retrieves a remote control device 32 at reference 502. If remote control device 32 is a portable device, such as in the embodiments of Figures 4 through 8 and 9-10, the remote control device 32 is also donned by the operator, for example, by securing the tether strap 190 to the operator's finger or fingers. Next, the operator of the vehicle initiates an ignition sequence to enable the vehicle 10 to be put into operation, that is, the operator starts the vehicle 10 at 504. In order to start the vehicle 10, one can reach require the operator to provide login information to the vehicle 10. This information can be provided, for example, by entering a personal identification number (PIN) at an oncAnn control panel / i znz / B / v of the vehicle 10, through the use of a remote control to provide the login ID to the vehicle 10, or the operator PIN may be encoded in a memory device, such as a radio frequency identification (RFID) chip that is integrated into the remote control device 32. Next, the operator initiates a pairing operation with the vehicle 10 at 506, and then the pairing system 34 is paired with the remote control device 32 used by the operator with the vehicle 10 at 508. Next The details of two exemplary pairing operations will be described in detail with reference to Figures 17 and 18. Once paired, system 8 may provide such a visual indication, for example, by displaying a message on vehicle 10, illuminating LED 424 in a predetermined color, making an audible or visual signal, etc., which indicate that the pairing is complete. In accordance with one aspect of the invention, remote control device 32 can be unpaired from vehicle 10 when vehicle 10 is turned off. Other exemplary methods for unpairing remote control device 32 from vehicle 10 are described below in example use cases. The operation of two example pairing systems 34 is described in connection with Figures 17 and 18, respectively, which are flowcharts of example methods 550 and 600 for pairing a vehicle 10 and a remote control device. 32 through the use of a pairing system 34 that forms part of the charging station 50 on board the vehicle 10. The descriptions of the methods 550 and 600 of figures 17 and 18 begin when the remote control device 32 is inserted in the charging station 50, which corresponds to step 506 of Figure 16. Referring to Figure 17 and method 550, at reference 552, when the second presence contact 222 is activated by the first presence contact 212 as the remote control device 32 is inserted into the charging station 50, the BLE radio 402 of the charging station 50 is enabled in such a way as to start scanning or listening for nearby BLE transmissions. As discussed in the preceding paragraphs, coupling of the second presence contact 222 via the first presence contact 212 can also cause the current limiter 406 to be enabled in such a way that power can be provided from the vehicle. 10 to the charging contacts 210 from the charging elements 220, which will cause the rechargeable power supply 180 of the remote control device 32 to be recharged. Pursuant to the above, pairing and charging operations they are initiated by the single action of pairing the remote control device 32 with the charging station 50. Instead of using BLE transmissions to pair the remote control device 32 with the vehicle controller 103, the control device Remote 32 can be paired with vehicle controller 103 by means of direct physical contact between, for example, charging contacts 210 and charging elements 220. Alternatively, dedicated pairing contacts may be provided (not shown). shown) on the remote control device 32 and the vehicle 10, for example, on the charging station 50, in order to oncAnn / i ζπζ / β / υ pair the remote control device 32 with the vehicle controller 103 to through direct physical contact. These pairing contacts on the remote control device 32 and the vehicle 10 could be connected to each other simultaneously with the connection of the charging contacts 210 to the charging elements 220, in such a way that the pairing process Pairing could be presented at the same time as the upload process. These matchmaking contacts could only be used to carry out message exchanges for matching operations. In accordance with one aspect of the invention, where the pairing process is carried out wirelessly, at 554, the remote control device 32 detects that a voltage is present on its charging contacts 210 and begins to transmitting BLE announcements through the wireless transmitter 178, indicating that the remote control device 32 is available to communicate with nearby devices. In response, the BLE radio 402 of the charging station 50 may receive one of the broadcast announcements and, at 556, may issue a BLE scan request directed to the specific remote control device 32 associated with the received announcement. If the BLE radio 402 of the charging station 50 were to identify two or more available remote control devices 32 for pairing, that is, by receiving BLE announcements from two or more remote control devices 32 while scanning or listening for nearby BLE transmissions, the vehicle 10 cannot be paired with any of the available remote control devices 32 and may require the operator to repeat the pairing process by removing the remote control device 32 from the charging station 50 and then reinsert the remote control device 32 into the charging station 50. At reference 558, the remote control device 32 responds to the scan request with a unique identification code, which is received by the BLE radio 402. At reference 560, the vehicle 10 checks the code and instructs the BLE radio 402 to open a BLE connection and begin communicating with the remote control device 32. At 562, once a communication session has been established between the remote control device 32 and the charging station 50, a predetermined pairing algorithm may be implemented between the remote control device 32 and the charging station. 50 in order to complete the pairing operation at reference 564. Once paired, the vehicle 10 communicates wirelessly with the remote control device 32, and the controller 103 of the vehicle 10 is able to implement the wireless requests received from the remote control device 32. In the example flowchart described above with respect to Figure 17, a similar method can be carried out to pair the remote control device 32 with the vehicle 10 through the use of, for example, one or more of the charging elements 220 of the charging station 50 and the charging contacts 210 of the remote control device 32, or the dedicated pairing contacts mentioned in the previous paragraphs. Instead of messages being transmitted and received via wireless or BLE radios, the same or equivalent types of messages can be communicated via oncRnn / ι znz / B / v 220 / 210 elements / contacts via of various protocols. The messages can be modulated and transmitted through one of the elements / contacts 220 / 210 that provide the voltage. In either case, the pairing of the vehicle 10 and the remote control device 32 can occur simultaneously with the charging of the rechargeable power supply 180 of the remote control device 32. Referring to Figure 18 and method 600, at reference 602, when the second presence contact 222 is activated by the first presence contact 212 as the remote control device 32 is inserted into the charging station 50, the BLE radio 402 of the charging station 50 is enabled with a predetermined wait time, for example, 1500 ms, in such a way as to start scanning or listening for nearby BLE transmissions from the listening devices. remote control 32. As discussed in the previous paragraphs, activation of the second presence contact 222 by means of the first presence contact 212 can also cause the current limiter 406 to be enabled in such a way that it can be provide power from the vehicle 10 to the charging contacts 210 from the charging elements 220, which will cause the rechargeable power supply 180 of the remote control device 32 to be recharged. Pairing and charging operations are initiated by the sole action of docking the remote control device 32 with the charging station 50 in such a way that a component of the remote control device 32 physically contacts an element of the charging station 50. Instead of using BLE transmissions to pair remote control device 32 with vehicle controller 103, remote control device 32 can be paired with vehicle controller 103 through direct physical contact between, for example, charging contacts 210 and charging elements 220. Alternatively, dedicated pairing contacts (not shown) may be provided on remote control device 32 and vehicle 10, for example, on the charging station 50, in order to pair the remote control device 32 with the vehicle controller 103 through direct physical contact. These pairing contacts on the remote control device 32 and the vehicle 10 could be connected to each other simultaneously with the connection of the charging contacts 210 to the charging elements 220, in such a way that the pairing process pairing can occur at the same time as the charging process. These matchmaking contacts could only be used to carry out the exchanges of messages for matching operations. At 604, the signal strength of the BLE transmissions between the wireless transmitter 178 and the BLE radio 402 can be decreased during the pairing process to help prevent other nearby vehicles 10 from receiving the BLE transmissions. BLE from the remote control device 32. In accordance with one aspect of the present invention, where the pairing process is performed wirelessly, at 606, the remote control device 32 detects that a voltage is present on its charging contacts 210 and begins to transmit the announcements in BLE through the wireless transmitter 178 at a predetermined rate, for example, at a rate of oncRnn / ι znz / B / v ms, and with a predetermined waiting time, for example, with a time waiting time of 2000 ms, indicating that the remote control device 32 is available for communication with nearby vehicles 10. If the BLE radio 402 of the charging station 50 were to identify two or more remote control devices 32 available for pairing, that is, by receiving BLE announcements from two or more control devices remote control 32 while scanning or listening for nearby BLE transmissions, vehicle 10 may not pair with any of the available remote control devices 32 and may require the operator to repeat the pairing process by removing the remote control device 32 from the charging station 50 and then reinsert the remote control device 32 into the charging station 50. The charging station 50 may provide the power to charge the rechargeable power supply 180 for up to approximately, for example, 1000 ms before BLE announcements are sent from the wireless transmitter 178. The charging of the power supply of rechargeable power 180 by means of the charging station 50 will be discussed in detail below. In response to receiving the BLE announcements from the wireless transmitter 178, the BLE radio 402 of the charging station 50 may, at reference 608, issue a BLE scan request. At reference 610, remote control device 32 receives the scan request from BLE radio 402 and uses the radio address of BLE 402 to create a unique identification code, which remote control device 32 sends. back to BLE radio 402 at reference 612. At reference 614, vehicle 10 checks the code and instructs BLE radio 402 to open a BLE connection and begin communication with remote control device 32. It should be noted that if vehicle 10 receives more than one code identification code during step 614, for example, if the vehicle 10 receives the identification codes from two different remote control devices 32, the pairing will fail, the vehicle 10 may issue an error message or other warning, and it will be required to the operator repeats the pairing process by removing the remote control device 32 from the charging station 50 and then reinserting the remote control device 32 into the charging station 50. At 616, once a communication session has been established between the remote control device 32 and the charging station 50, the pairing operation can be completed, and the signal strength of the BLE transmissions between the Wireless Transmitter 178 and BLE Radio 402 can be boosted back up to their normal levels at the reference 618. The operator could be required to perform an action on reference 620 as a test to confirm that the remote control device 32 is functional and can communicate with the charging station 50, for example, such as by pressing a sequence of buttons on the remote control device 32, for example, by pressing the horn button 197B and the brake button 197C simultaneously. Once paired, the vehicle 10 communicates wirelessly with the remote control device 32, and the controller 103 of the vehicle 10 is capable of implementing the oncRnn / i ζπζ / β / υ wireless requests received from the device. remote control 32. In accordance with some aspects of the invention, a pairing period (which is a period of time it takes to establish communication between the remote control device 32 and the vehicle 10 and beginning with steps 552 / 602 and ending with steps 564 / 616) can be less than the charge period (which is the time it takes to charge the rechargeable power supply 180 to a desired state of charge at the charging station 50), where charging of the rechargeable power supply 180 will be discussed below in connection with Figures 21 and 22. Referring to Figure 19, according to a further aspect of the present invention, after carrying out work operations, the vehicle operator may need to temporarily leave the vehicle 10, for example, to take a break. An example method 700 is illustrated for shutting down, restarting, and re-pairing the vehicle 10 with the remote control device 32 used by the operator. The operator shuts down the vehicle 10 at 702, such as to take a break, etc. After some time, the vehicle operator starts the vehicle 10 again. During this pause time, the remote control device 32 may continue to be paired with the vehicle 10 for up to a predefined period of time. This maintained pairing status between the vehicle 10 and the remote control device 32 can be indicated, for example, on a touch screen (not shown) provided in the vehicle 10, by means of the illumination of the LED 424 in a predetermined color. determined, pattern, etc. Therefore, if the operator starts the vehicle 10 again before the time period previously defined at 704 expires, the vehicle 10 can detect the remote control device 32 at reference 706, where the control device remote 32 remains paired with vehicle 10. In this sense, the operator may or may not have to take some action on reference 708, such as pressing a button on vehicle 10, for example, on charging station 50, on the touch screen, etc., or press a sequence of buttons on the remote control device 32. A successful operator action at reference 708 results in a confirmation of the pairing between the remote control device 32 and the vehicle 10 at reference 710. A visual signal may be displayed on the indicator (the LED 424) to indicate the pairing. eg by lighting the LED 424 in the second color indicated above. Alternatively, in accordance with this aspect of the invention, if the operator starts the vehicle 10 again after the time period previously defined at 712 expires, the operator may be required to re-pair the device. remote control 32 with the vehicle 10 as with the initial pairing, for example, by inserting the remote control device 32 into the charging station 50 at reference 714. Referring to Figure 20, an example method 800 is illustrated for re-establishing communication between remote control device 32 and vehicle 10 after a period in which no vehicle-related activity has occurred. At 802, the controller 103 in the vehicle 10 detects that no vehicle-related activity has been carried out during oncAnn / i znz / B / v a certain period of time after communication has been established between the remote control device 32 and the vehicle 10. Example activities related to the vehicle include driving the vehicle 10 (either manually through the use of the hand controls at the operator station 20, other hand controls, for example, in the side of the vehicle 10, or via the remote control device 32), standing on the platform 21, moving or placing an item on the cargo handling assembly 12, etc. At 804, if no vehicle-related activity is carried out for more than a first predetermined amount of time after communication is established between the remote control device 32 and the vehicle 10, the communication is terminated. between the remote control device 32 and the vehicle 10, and must be restored through the use of the pairing system 34 in reference 806, that is, by inserting the remote control device 32 in the charging station 50 in the vehicle 10. This finished pairing status between the vehicle 10 and the remote control device 32 can be indicated, for example, on the touch screen, by lighting up the LED 424 in a predetermined color, pattern, etc. . At 808, if no vehicle-related activity is performed for less than a predetermined second amount of time after communication is established between the remote control device 32 and the vehicle 10, the second amount of time previously determined equal to or less than the first previously determined amount of time, communication between the remote control device 32 and the vehicle 10 is terminated, but can be re-established without the pairing system 34, for example, by executing a confirmation method through the use of the remote control device 32 at 810. The confirmation method may comprise, for example, the operator performing a button sequence on the remote control device 32, for example, such as by long pressing one or more of the buttons 197 A to C. This state of pairing between the vehicle 10 and the remote control device 32 can be indicated, for example, on the touch screen, by means of lighting the LED 424 in a predetermined color, pattern, etc. 21 is a flowchart of an example method 900 for charging a remote control device in accordance with the principles of the present invention. In particular, the remote control device may be the same or similar to the remote control device 32 described herein, and may include a wireless communication system 456 that includes a wireless transmitter 178 (for example, capable of having a one-way or two-way communication), a rechargeable power supply 180, and at least one control (eg, controls 196 A through C) that causes the wireless transmitter 178 to wirelessly transmit a request to a controller of a material handling vehicle 10. The method 900 for charging a remote control device 32 begins at 902 when contact is initiated between a component of the remote control device 32 and an element of a charging station 50, wherein the charging station 50 is located at the vehicle 10 and then contact between the remote control device component and the charging station element is detected. As described above, the remote control device 32 may include one or more oncRnn / ι znz / E / v charging contacts 210 that are each arranged in such a way as to activate a corresponding charging element 220 of the charging station 50, such that when connected, a second presence contact 222 or similar device activates a corresponding first presence contact 212 to detect or sense that charging contact 210 and charging element 220 are in contact. contact with each other. However, other components of the remote control device 32 and other elements of the charging station 50 can be used to detect or sense the initiation of contact. Next, at 904, a charging period is initiated, in which power is supplied from the charging station 50 to the rechargeable power supply 180. As described above, as an example, the The charging station 50 circuit is configured in such a way that when contact is detected between the charging contact(s) 210 and the charging element(s) 220, power is supplied from the charging station 50 to the charging devices. charge contacts 210 of the remote control device 32 for charging the rechargeable power supply 180. Once the rechargeable power supply 180 is substantially fully charged (or is charged to the desired amount of less than a substantially full charge state), the remote control device 32 can be removed from the charging station 50. In this way, the method of figure 21 continues, at reference 906, with the interruption of the contact between the component of the remote control device and the element of the charging station, and with the detection of the interruption of the contact between the remote control device component and charging station element. As described above, the charging contact(s) 210 of the remote control device 32 and the charging element(s) 220 of the charging station 50 are arranged in such a way that, as the two systems are disconnected , that state can be detected or perceived. An example is the second presence contact 222 that can detect when the remote control device 32 is being removed from the charging station 50. Finally, upon detection of this interruption at 906, charging station 50 may cease supplying power from charging station 50 to rechargeable power supply 180 at 908, thereby The charging period ends in this way. It should be noted that the second presence contact 222 may be located on the remote control device 32, and its disconnection may result in the power supply from the charging station 50 to the rechargeable power supply 180 being stopped. Power supply from the charging station 50 to the rechargeable power supply 180 can also be stopped when the rechargeable power supply 180 is charged to the desired amount (either fully charged or fully charged to a desired amount). less than full charge), as described in this document. Method 900 may include other optional steps shown in Figure 21. For example, method 900 may also include confirmation of communication establishment between remote control device 32 and vehicle 10 at reference 910, for example , with at least one audible or visual signal. The method 900 may further include, while the remote control device component is in contact with the charging station element, establishing an oncAnn / i ζπζ / β / υ communication between the remote control device 32 and the vehicle 10 (eg, pairing) during a pairing period at reference 912, such that controller 103 receives transmissions from remote control device 32 and is capable of implementing wireless requests from the control device remote 32. This communication between the remote control device 32 and the vehicle 10 can be established in a concurrent manner during charging of the rechargeable power supply 180 at the charging station 50, such that the pairing period and the charging period overlap. In at least some embodiments, the pairing period is less than or equal to the charging period. In addition, method 900 may include, at 914, displaying a state of charge of the rechargeable power supply 180 in vehicle 10, for example, at charging station 50, wherein the state of charge of the rechargeable power supply 180 can be displayed in the vehicle 10 both when the rechargeable power supply 180 is being charged and during the use of the remote control device 32. The state of charge of the rechargeable power supply 180 it can be displayed, for example, through a series of lights, each of the lights representing a level of a state of charge of the rechargeable power supply 180. Figure 22 is a flow chart of another example method 950 for charging a remote control device in accordance with the principles of the present invention, such as the remote control device 32 described herein, which comprises a wireless communication system 456 including a wireless transmitter 178 (eg, capable of one-way or two-way communication), a rechargeable power supply 180, and at least one control (eg, the controls 196 A through C) that causes the wireless transmitter 178 to wirelessly transmit a request to a controller of a material handling vehicle 10. As used herein, the term control, when used to describe a control of the remote control device 32 is intended to include any structure capable of providing the desired function, which includes, but is not limited to, buttons, switches, dials, etc. The method 950 for charging a remote control device 32 begins at 952 by initiating contact between a component of the remote control device 32 and an element of a charging station 50, wherein the charging station 50 is located. in the vehicle 10, and then contact between the remote control device component and the charging station element is detected. As described in the preceding paragraphs, the remote control device 32 may include one or more charging contacts 210 that are each arranged in such a way as to activate a corresponding charging element 220 of the charging station 50, such that when activated, a second presence contact 222 or similar device activates a corresponding presence contact 212 to detect or sense that the load contact(s) 210 and load element(s) 220 are in contact. contact each other. However, other components of the remote control device 32 and other elements of the charging station 50 may be used to detect or sense the initiation of contact. In step 954, the current state of charge of the oncAnn / i ζπζ / β / υ rechargeable power supply 180 is determined. Step 954 can be carried out before or after step 952, that is, the state of charge of the rechargeable power supply 180 can be communicated to the charging station 50 both when the remote control device 32 is docked with the charging station 50 and during use of the remote control device 32 by of the operator, as described in this document. Based on the current charging state of the rechargeable power supply 180 and after step 952 is performed, in step 956, a charging period is started, in which power is supplied from charging station 50 to rechargeable power supply 180. In an exemplary embodiment, at step 958A, if the voltage of rechargeable power supply 180 is below a voltage threshold VT, the charging station charge 50 charges the rechargeable power supply 180 at a first higher power level PL1. According to this embodiment, in step 958B, if the voltage of the rechargeable power supply 180 is above the voltage threshold VT, the charging station 50 charges the rechargeable power supply 180 at a second level. lowest power PL2. The resulting charging period in either case, i.e., at step 958A or at step 958B, can be approximately the same, i.e., charging the rechargeable power supply 180 to the desired amount above or below. below the threshold voltage VT can take about the same time. While only two power levels PL1, PL2 associated with a single threshold voltage VT are described herein, additional threshold voltages and power levels could be used, where the charge period can always be approximately the same time. regardless of the charge level of the rechargeable power supply 180 when inserted into the charging station 50. In addition, an equation could be used to dynamically set the power level according to the current state of charge of the 180 rechargeable power supply. Once the charging period has been completed, i.e., once the rechargeable power supply 180 is charged to the desired amount, i.e., substantially fully charged or charged to less than a substantially state of charge For example, by virtue of the sensed temperature if that technology is present in the system 8, or if less than a full charge is desired, the remote control device 32 can be removed from the charging station 50. Thus, the method of Fig. 22 continues, at step 960, with the breaking of contact between the component of the remote control device and the element of the charging station, and the detection of the breaking of contact between the component of the remote control device and the element of the charging station. As described in the preceding paragraphs, the charging contacts 210 of the remote control device 32 and the charging elements 220 of the charging station 50 are arranged in such a way that, as the two systems are disconnected, that state can be detected or perceived. An example is the second presence contact 222 that can detect when the remote control device 32 is being removed from the charging station 50. Finally, upon detection of this interruption at reference 960, or when the rechargeable power supply 180 is charging to the desired amount, the onoRnn / i ζηζ / Β / γ charging station may cease supplying power from the charging station 50 to the rechargeable power supply 180 at 962, thereby terminating the charging period. Method 950 may include other optional steps shown in Figure 22. For example, method 950 may also include confirmation of communication establishment between remote control device 32 and vehicle 10 at reference 964, for example , with at least one audible or visual signal. Method 950 may further include, while the remote control device component is in contact with the charging station element, establishing a communication between the remote control device 32 and the vehicle 10 (for example, pairing ) during a pairing period at 966, such that controller 103 receives transmissions from remote control device 32 and is capable of implementing wireless requests from remote control device 32. This communication between the remote control device 32 and vehicle 10 can be established in a concurrent manner during charging of the rechargeable power supply 180 at the charging station 50, such that the pairing period and the charging period overlap . In at least some embodiments, the pairing period is less than or equal to the charging period, although the matching period may be greater than the charging period, as will be discussed in more detail below. Additionally, method 950 may include, at 968, displaying a state of charge of the rechargeable power supply 180 in vehicle 10, for example, at charging station 50, wherein the state of the charging of the rechargeable power supply 180 can be displayed on the vehicle 10 both when the rechargeable power supply 180 is being charged and during the use of the remote control device 32. The charging status of the rechargeable power supply rechargeable power 180 can be displayed, for example, through a series of lights, each of the lights representing a level of a charge state of the rechargeable power source 180. In accordance with one aspect of the invention, the charging period may depend on the capacity of the rechargeable power supply 180, the charging speed, or the power level that is supplied by the charging station 50, and / or the state of charge of the rechargeable power supply 180 when inserted into the charging station 50. Thus, a desired charging period could be achieved regardless of the current state of charge of the power supply. rechargeable power supply 180 when the remote control device 32 is placed in the charging station 50. For example, the current state of charge of the rechargeable power supply 180 may be known by the vehicle 10, for example, the The charge status of the rechargeable power supply 180 can be communicated to the charging station 50, as described herein. The charging station 50 may be instructed, for example, by the controller 103, to supply power to the rechargeable power supply 180 at different rates or levels depending on the state of charge of the power supply. rechargeable battery 180 when the remote control device 32 is placed in the charging station 50, in such a way that the charging period is generally approximately the same time, regardless of the charging status of the oncAnn / i znz / B / v the rechargeable power supply 180 when the remote control device 32 is placed in the charging station 50. For example, as discussed in the preceding paragraphs with reference to steps 958 A / B of Figure 22, if the state of charge of the rechargeable power supply 180 is a lower first state of charge, then a higher first rate or power level can be delivered from the charging station 50 to the rechargeable power supply 180. If the state of charge of the rechargeable power supply 180 is one second higher state of charge, then a lower second rate or power level can be supplied from the charging station 50 to the rechargeable power supply. rechargeable power 180. The resulting charge period in the two cases could be approximately the same time, for example, within approximately 0.5 seconds of the desired charge period. Any number of charge states of the rechargeable power supply and the corresponding speeds or power levels could be implemented in such a way that the time required to charge the rechargeable power supply 180 is within the charging period. wanted. In addition, the life of the rechargeable power supply 180 can be increased when charged at a lower power level. Therefore, an additional advantage of a charge period consistent with the present invention is that the rechargeable power supply 180 sometimes charges at a lower power level, for example, when the state of charge of the rechargeable power supply 180 when inserted into the charging station 50 is the second highest state of charge as discussed above. Therefore, charging the rechargeable power supply 180 at different power levels, as described herein, may increase the life of the rechargeable power supply 180, rather than if The Rechargeable Power Supply 180 will charge at a consistent, higher power level with each charge. Furthermore, while the pairing period, which is described herein as the period of time it takes to establish communication between the remote control device 32 and the vehicle 10, may be less than or equal to the pairing period charging, the charging period can also be less than the pairing period. As an example, it can be determined that the rechargeable power supply 180 need not be fully charged to function for a desired period of use. For example, a full charge of the rechargeable power supply 180 can provide an operating time that is longer than a desired period of use (for example, an operator's shift), such that the power supply Rechargeable Power 180 does not need to be fully charged to be operable for the desired period of use. In this case, the charging station 50 can be programmed in such a way as to charge the rechargeable power supply 180 to a less than full state of charge, which would still be sufficient for the remote control device to be operational. throughout the period of desired use. The time it takes to charge the rechargeable power supply 180 to this less than full charge state may be less than the pairing period. Other situations may also occur where the charging period may be less than the pairing period. QncRnn / ι znz / B / v Referring to Figure 23, the principles of the present invention may also be implemented as a kit 1000 for retrofitting to a material handling vehicle 10'. In Figure 23, elements similar or identical to those described above with reference to Figures 1 to 22 include the same reference numeral followed by a prime symbol (j. An element that is described with respect to Figure 23 but which is not specifically shown in Fig. 23 is equivalent to the element having the same reference symbol as described above, but without the prime symbol. Vehicle 10' may include a vehicle controller 103' that responds to wireless requests from an associated remote control device 32' that is used by an operator that interacts with vehicle 10' similar to vehicle types 10 and the remote control devices 32 described above. An example kit 1000 would include a charging station 50' in the vehicle 10', where the charging station 50' is for charging a rechargeable power supply 180' of the remote control device 32', where the station charging station 50' is electrically coupled to a vehicle power source, and a receiver 102', such as a BLE radio coupled in a communicable manner to vehicle controller 103' 10'. In particular, the charging station 50' is configured in such a way that the rechargeable power supply 180' is charged to a desired amount (one full charge or less than full charge as described herein) in the charging station 50' within a desired charging period. The kit 1000 may further include a pairing system 34' to establish communication between the remote control device 32' and the vehicle 10' such that the controller 103' is capable of implementing wireless requests from the remote control device. remote control 32'. Matching system 34', for example, may be similar to matching system 34 and may implement the matching algorithms detailed in Figure 17 and / or Figure 18. Therefore, kit 1000 may also include a pairing indicator, for example, the visual indicator 424', which confirms the establishment of communication between the remote control device 32' and the vehicle 10'. Furthermore, the pairing system 34' can be configured in such a way that the pairing period (a period of time it takes to establish communication between the remote control device 32' and the vehicle 10') can be less than or same as charge period (a period of time it takes to charge the 180' Rechargeable Power Supply to the desired amount). The pairing period can also be longer than the charging period. The pairing system 34' can be incorporated into the charging station 50' or it can be a separate item. It is contemplated that the communication between the remote control device 32' and the vehicle 10' is established in a concurrent manner during the charging of the rechargeable power supply 180' at the charging station 50', that is, the period pairing and charging period may overlap. Furthermore, in some embodiments, the communication between the remote control device 32' and the vehicle 10', and the charging of the rechargeable power supply 180' at the charging station 50' are initiated with a single action. For example, the single action may comprise physical contact with a component of the remote control device, eg, one or more charging contacts 210 as oncAnn / i znz / B / v described above, with an element of the charging station. load, eg, one or more corresponding load elements 220 as described in the preceding paragraphs. The remote control device 32' that is used in combination with kit 1000 may be the same as the remote control devices 32 described herein. Therefore, a remote control device manufactured for use with a vehicle 10 that includes an integrated charging station 50 and related components could also be used with a kit 1000 for use with an existing vehicle 10'. As described above with respect to charging station 50, charging station 50' of kit 1000 may also include guide structure 420' for aligning remote control device 32' in the proper orientation for charging the power supply. of rechargeable power 180'. The kit 1000 may also include an indicator (eg, LEDs 404', light, or the like) that can be configured such that it can be attached to the vehicle 10' to indicate a state of charge of the battery. 180' rechargeable power supply. The indicator can indicate the charging status of the rechargeable power supply 180' both when charging the rechargeable power supply 180' at the charging station 50' and during use of the remote control device 32'. In some embodiments, the indicator comprises a series of lights, each light representing a state of charge level of the rechargeable power supply 180'. The kit 1000 includes at least one charging element 220' in the charging station 50' that connects to at least one corresponding charging contact 210' of the remote control device 32'. Furthermore, at least one of the remote control devices 32' or the charging station 50' includes a presence contact 212' or 222' that detects whether at least one corresponding charging contact 210' and at least one element of load 220' are correctly connected with each other. If a correct connection is detected, power transfer to the rechargeable power supply 180' of the remote control device 32' via the charging station 50' is enabled, and if a correct connection is not detected, no transfer of power to the rechargeable power supply 180' via the charging station 50' is enabled. In at least some embodiments, the remote control device 32' comprises at least two charging contacts 210' or at least four charging contacts 210' that are positioned in such a way as to connect charging elements 220' corresponding at the charging station 50'. The arrangement of the remote control device 32' and the charging station 50' of the kit 1000 is configured in such a way that the presence contact 212' or 222' indicates the removal of the remote control device 32' from the station. charging contact 50', which stops the transfer of power to the rechargeable power supply 180' from the charging station 50', before the at least one charging contact 210' disconnects from the at least one element load 220 'corresponding. Therefore, the power transfer from the charging station 50' to the rechargeable power supply 180' stops before the at least one charging contact 210' disconnects from the at least one charging element. 220' corresponding. The 1000 kit can also use non-contact charging, or by induction, in which the source of QncRnn / ι znz / B / v rechargeable power supply 180' of remote control device 32' can be charged by being in close proximity to, or on the surface of, a compatible induction charging station (not shown). Said induction charging station can be located, for example, in a vehicle steering or driving control 10' in such a way that the rechargeable power supply 180' can be charged while the operator is manually driving the vehicle. vehicle 10' from operator station 20'. The kit 1000 in accordance with this aspect of the invention may be located at least partially in the vehicle's steering control or other vehicle component that facilitates contactless or inductive charging of the rechargeable power supply 180', for example, the rechargeable power supply 180' may be charged by the operator holding the drive or steering control. Kit 1000 may utilize any of the other features and / or functions of remote control device 32' and charging station 50' as described above for Figures 1-22. It is noted that if the departing vehicle 10' for use with kit 1000 were previously configured in such a way as to interface with a wireless remote control device, the controller logic in vehicle controller 103' might need to be upgraded to be used with kit 1000, and a receiver that already provided in the vehicle 10', i.e. to receive wireless requests from a remote control device that was used with the vehicle 10' before the kit 1000 was installed in the vehicle 10', can be turned off instead of the receiver 102' of the kit 1000, that is, to be used with the remote control device 32' associated with the kit 1000. Referring now to Figure 24, a remote control device 32 in accordance with one embodiment of the invention may be incorporated into a glove garment 1100. Use of the glove garment 1100 eliminates the need for the fastening strap 190, and the first control 196A can be provided on a finger of the glove 1100 instead of being part of the upper housing 174, but the remaining components of the remote control device 32 illustrated in Figure 24 can be the same. same or similar to those of the remote control device 32 of Figures 4 to 7, including a form of the part of the upper casing 174 that connects with the charging station 50 in the vehicle 10. Therefore, the charging station charging station 50 in the vehicle 10 can be the same as the charging station 50 described above, that is, because the charging station docking part of the upper case 174 of the remote control device 32 incorporated into the The glove garment 1100 can have the same dimensions as the charging station engaging portion of the upper case 174 of the remote control device 32 in the embodiment of Figures 4 to 7, the same charging station 50 could be used since either with the finger-mounted remote control device 32 of Figures 4 to 7, or with the remote control device 32 that is incorporated into the glove garment 1100 of Figure 24. If the remote control device 32 incorporated into the glove garment 1100 were to be used in conjunction with the inductive charging technology disclosed herein, the inductive charging structures may be incorporated, for example, in the palm of the glove garment 1100. Such load structures in the glove garment 1100 could be used with the oncRnn / ι znz / B / v load elements incorporated, for example, in a vehicle steering control paired with the gauntlet device. remote control 32, in which case, a rechargeable power supply of the remote control device 32 could be charged while the operator is holding the steering control. In accordance with some additional aspects of the present invention, there may be conditions and / or events that cause the vehicle 10 to become unpaired from the remote control device 32, wherein a full pairing process through the use of the remote control device 32 may be necessary. pairing system 34, as described herein, to re-pair vehicle 10 with remote control device 32. There may be other conditions or events that cause vehicle 10 to become unpaired from the control device remote 32, where something other than a full pairing process may be required through the use of the pairing system 34, as described herein, to re-pair the vehicle 10 with the remote control device 32. Several example use cases regarding unpairing and re-pairing will now be described. A first example use case can be presented by turning off the vehicle 10. According to this first use case, the remote control device 32 is unpaired from the controller 103 and requires a complete pairing process through the use of the system. 34, as described herein, in order to re-pair the vehicle 10 with the remote control device 32. According to this first exemplary use case, a pairing process may be required. full pairing using the pairing system 34 in order to re-pair the remote control device 32 with the vehicle 10 each time the vehicle 10 is turned off. A second exemplary use case may be substantially as described above with respect to Figure 19, where the vehicle operator temporarily leaves the vehicle 10, for example, to take a break. The details of this second example use case are discussed above with reference to Figure 17 and will not be repeated again. The third and fourth exemplary use cases may occur if no vehicle related activity is performed for more than a first predetermined amount of time after communication is established between the remote control device 32 and the vehicle 10 (third use case) or if no vehicle-related activity is performed for less than a predetermined second amount of time after communication between the remote control device 32 and the vehicle 10 is established (fourth use case). The details of these third and fourth example use cases are discussed above with reference to Figure 20 and will not be repeated again. Several exemplary use cases may arise when dealing with multiple remote control devices 32 and / or multiple vehicles 10. In a fifth exemplary use case, suppose that a first remote control device 32 is currently paired with a first vehicle 10, and a second remote control device 32 is currently paired with a second vehicle 10. In this fifth use case, the first remote control device 32 is inserted into the charging station 50 of the second vehicle 10. In this circumstance , the charging station 50 of the second vehicle 10 can charge the source QncRnn / ι znz / B / v rechargeable power supply 180 of the first remote control device 32, the first remote control device 32 may become unpaired from the first vehicle 10, and the second remote control device 32 may become unpaired of the second vehicle 10. The first remote control device 32 will not be paired with the second vehicle 10 in the fifth use case. In a sixth example use case and with reference to Figure 24, suppose that a remote control device 32 is currently paired with a first vehicle 10A in such a way that the remote control device 32 communicates wirelessly with the first vehicle 10A, and a second vehicle 10B is not currently paired with a remote control device. In this sixth use case, the remote control device 32 is paired with the second vehicle 10B through the use of a pairing process, for example, by inserting the remote control device 32 into the charging station 50. of the second vehicle 10B. Through the use of this pairing process, the charging station 50 of the second vehicle 10B can charge the rechargeable power supply 180 of the remote control device 32, and the remote control device 32 can become paired with the second vehicle 10B in such a way that the remote control device communicates wirelessly with the second vehicle 10B. This pairing process can also cause the remote control device to become unpaired from the first vehicle 10A such that the remote control device no longer communicates wirelessly with the first vehicle 10A. Once the remote control device 32 is paired with the second vehicle 10B and unpaired from the first vehicle 10A, the second vehicle 10B can respond to remote requests from the remote control device 32, while the first vehicle 10A can no longer. it can respond to remote requests from the remote control device 32. As described in the preceding paragraphs, the wireless communication system 456 of the remote control device 32 and / or the BLE radio 402 of the charging station 50 can be configured, for example, in such a way as to enter a low power mode when remote control device 32 is being paired with second vehicle 10B and / or remote control device 32 rechargeable power supply 180 is being charged at charging station 50, for example, for ensure that only a remote control device 32 within a minimum distance, corresponding to the signal strength of the communications received from the remote control device 32, from the charging station 50 is recognized as the control device remote 32 for the second vehicle 10B with which to pair. According to the sixth example use case, prior to the matching process, the second vehicle 10B may be dispatched, for example, by a warehouse management system (WMS) in communication with the second vehicle. 10B, to a designated location, such as, for example, the location of the operator, the location of the first vehicle 10A, the end of an aisle where the operator and / or the first vehicle are located 10A, a designated waiting area , etc. The second vehicle 10B can be an unloaded vehicle, that is to say, free of a load and therefore ready to transport the items to be picked up by the operator. The second vehicle 10B may be instructed to move to the designated location by the warehouse management system (WMS) oncRnn / i znz / B / v, for example, when the first vehicle 10A is loaded. with a desired number of pickup items and is ready to be shipped to a different location, i.e., a location that is different from the current location of the vehicle 10, such as a loading dock (LD). or other location to which the pickup items are to be shipped in the first vehicle 10A. The operator may also request that the second vehicle 10B be sent to the designated location, for example, through the use of a control on the first vehicle 10A, over a headset, etc. Once the second vehicle 10B is paired with the remote control device 32, the second vehicle 10B can no longer implement the commands from the warehouse management system (WMS), such that the second vehicle 10B will only implement the wireless commands from the remote control device 32 with which it is paired. Once the remote control device 32 has unpaired from the first vehicle 10A, the warehouse management system (WMS) can send instructions to the first vehicle 1 DA to move to the loading dock (LD). , for its acronym in English) and / or to another location, such as a vehicle charging station (not shown). Through the use of this sixth example use case, an operator can quickly switch between vehicles 10A and 10B, resulting in increased work productivity and efficiency. In a seventh exemplary use case, suppose a first remote control device 32 is currently paired with a vehicle 10, and a second remote control device 32 is not paired with a vehicle. In this seventh use case, the second remote control device 32 is inserted into the charging station 50 of the vehicle 10. In this circumstance, the charging station 50 of the vehicle 10 can charge the rechargeable power supply 180 of the second remote control device 32, the first remote control device 32 may become unpaired with the vehicle 10, and the second remote control device 32 will not pair with the vehicle 10. In an eighth example use case, remote control device 32 is moved out of range of vehicle 10, i.e., in such a way that wireless transmitter 178 is no longer able to communicate with receiver 102 for a period of time. previously determined time. According to the eighth use case, the remote control device 32 may become unpaired from the vehicle 10. According to the eighth use case, if the remote control device 32 moves back until it is within range of the vehicle 10 after a pre-determined period of time, the vehicle 10 may need to be turned off and restarted in order for it to pair with a remote control device 32 using the pairing system 34, including pairing with the remote control device 32 previously paired, or a different remote control 32 device. If the remote control device 32 moves back within range of the vehicle 10 within the predetermined period of time, it may not be necessary to turn off and restart the vehicle in order for it to pair with the remote control device 32 previously Paired, for example, the previously paired remote control device 32 can be re-paired to the vehicle 10 by inserting the remote control device 32 into the vehicle's charging station 50. Pairing the vehicle 10 with a different remote control device 32 may require an onoRnn / i 7f\7iw vehicle to be shut down and restarted, regardless of how long the previously paired remote control device 32 was out of range of the vehicle 10. Additional example use cases related to pairing and / or charging periods will now be described. In a ninth exemplary use case, a desired state of charge, eg, a substantially full state of charge, of the rechargeable power supply 180 may be achieved by charging the rechargeable power supply. 180 at the 50 charging station in five seconds or less. According to this use case, the substantially full charge state of the rechargeable power supply 180 can provide a usage period of the remote control device 32 of at least eight hours. In a tenth example use case, the charging station 50 varies the power level that is delivered to the rechargeable power supply 180 based on the state of charge of the rechargeable power supply 180 when the device remote control unit 32 is inserted into the charging station 50, as described herein with respect to figure 22. A charging period according to the tenth use case will always be approximately four seconds, regardless of the state of charge of the rechargeable power supply 180 when the remote control device 32 is inserted into the charging station 50. Thus, a predictable charging period is achieved. It is noted that the type of transmissions that are sent by means of the remote control device 32 to the vehicle 10, eg requests, such as travel requests, may be other types of transmissions. For example, the transmissions may comprise location-based transmissions that inform the controller 103 of the vehicle 10 where the remote control device 32 is located in relation to the vehicle 10. Such location transmissions may be used by the controller 103 , for example, to follow the remote control device 32. Thus, the vehicle 10 can follow an operator using, holding or carrying the remote control device 32. The remote control device 32 could be charged by the station charging station 50 and could be paired with vehicle 10, as described herein. In accordance with another aspect of the present invention, charging of the rechargeable power supply 180 by means of the charging station 50 can be disabled while the vehicle 10 is in motion. This aspect of the invention may not apply to inductive charging of rechargeable power supply 180. Furthermore, if an operator is attempting to pair a remote control device 32 with a vehicle 10 that is in communication with the warehouse management system (WMS), the warehouse management system (WMS) acronym in English) can determine if the operational checks of one or more remote control devices have been carried out within a predetermined period of time, for example, within the last 12 hours. Such operational checks may include, for example, checks to ensure the operability of the controls of the remote control device 32, such as the horn and / or brake buttons oncAnn / i znz / B / v 197Β and 197C.
