Abstract:
It is desirable for operators of remote control systems to share the experience of controlling remote devices or appliances with others. To accomplish this, a system has evolved whereby a Slave transmitter is cable connected to a Master transmitter and a Master/Slave Switch is added to the Master transmitter enabling control to be transferred back and forth between the transmitters. The present invention replaces the hard-wired connection with a wireless facility consisting of a discrete or segmented programmable Slave Receiver and Adaptive Director Firmware Module that provides the desired functionality wirelessly and also provides significant case-of-use and compatibility features currently unavailable. By replacing the hard-wired connection with a wireless connection, a receiver that can accept and demodulate the wireless transmission, and adaptive programmable firmware (hardware and software) the present invention provides the desired transferability of control readily and conveniently without the limitations or constraints of the current art.

Description:
FIELD OF THE INVENTION 
       [0001]    The invention relates generally to remote control systems for model boats, airplanes, gliders, helicopters, cars and other appliances and, more particularly, to a wireless system enabling selectable manipulation and operation of the remote vehicle or appliance by two or more controllers. 
       BACKGROUND OF THE INVENTION 
       [0002]    An instrument, mobile vehicle, or other appliance can be remotely controlled by operating controls on a transmitting device which encode these operations into electrical signals and transmit them through a wired or wireless communications link. An appropriate receiver decodes the transmitted stream and directs suitable actuators to propel, and/or steer, and/or otherwise manipulate the remote device or appliance. Typically the communications link between the Master, or primary, Transmitter, and the remote receiver device consists of a modulated carrier wave. The carrier wave may function in any band within any spectrum including, but not limited to, sub-sonic, sonic, supersonic, infrared, light, radio or ultra radio frequencies. Remote controlled model airplanes, cars, helicopters and boats have developed a large following among the public. Remote controlled models typically include several servo controlled systems such as throttles, rudders, ailerons, brakes and similar systems which allow control over speed and direction of the vehicle or appliance by the application of control signals. Typically these signals are generated by a hand held controller as determined by the manual positioning of control sticks, levers and switches on the controller. While such controllers could be hardwired to the model, maximum freedom in maneuverability and the possibility of interaction between different hobbyists is achieved using wireless communication between the handheld controller and receiver/servo/actuator circuitry on the model. In this case circuitry within the controller continuously encodes the manual control stick, lever and switch positions into a representative composite signal, modulates and/or multiplexes the signal onto an acoustic, infrared, light, radio or microwave carrier wave, and radiates it to a remote receiver over a Primary Communications Link. The remote receiver captures the transmitted signal, de-modulates and/or de-multiplexes it and generates separate and distinct control signals to one or more servos or actuators. The servos or actuators convert the signals to physical movement or action thus directing the remote vehicle or appliance as intended. 
         [0003]    To share the experience and to aid in the training of other operators a method has evolved whereby control of the remote device is transferable to a second transmitter—the Slave, or trainer or secondary, Transmitter—which is physically connected by one or more pairs of wire to the Master, or primary, Transmitter. Conventionally this is done on an as desired basis—a cable, specially designed for specific manufactures&#39; transmitters, is plugged into the Master, or primary, Transmitter and the other end is plugged into the Slave, or secondary, Transmitter. The Slave, or secondary, Transmitter delivers a signal stream representing the positions of its control sticks, levers and switches. A Master/Slave Switch on the Master, or primary, Transmitter enables its operator to select which stream, the one generated within the Master, or primary, Transmitter or the one generated within the Slave, or secondary, Transmitter, modulates and/or multiplexes the Master, or primary, Transmitter&#39;s signal for transmission over the Primary Communications Link. In this way, the remote vehicle or appliance follows the designations of the Master, or primary, Transmitter operator when the switch is in the ‘Master’ position and follows the designations of the Slave, or secondary, Transmitter operator when the switch is in the ‘Slave’ position. By this means, control of the remote vehicle or appliance is transferable to either the Master, or primary, Transmitter&#39;s operator or the Slave, or secondary, Transmitter&#39;s operator. This arrangement is often referred to as a ‘buddy-box’ setup. 
       SUMMARY OF THE INVENTION 
       [0004]    The present invention supplants the current art requiring a wired connection between the Master, or primary, Transmitter and the Slave, or secondary, Transmitter with an innovative wireless Slave-To-Master Communications facility and Adaptive programmable hardware and software, or Firmware. 
         [0005]    The Slave-To-Master Communications facility and Adaptive Firmware of the present invention providing wireless interconnection between the Slave, or secondary, Transmitter and the Master, or primary, Transmitter may be manifested in many variations and configurations of encoding, modulating, multiplexing, decoding, demodulating, and de-multiplexing utilizing acoustic, infrared light spectrum, ultraviolet light spectrum, visible light spectrum, and/or electromagnetic spectrum carrier waves. 
         [0006]    The present invention consists of a programmable Slave Receiver and Adaptive Director Firmware Module, that may be instantiated as an integrated unit or segmented into a Slave, or secondary, Transmitter Signal Receiver sub-module and an Adaptive Director Firmware sub-module, which processes radiated signals emitted from a Slave, or secondary, Transmitter and propagated over a Slave-To-Master Communications Link. The Slave Receiver and Adaptive Director Firmware Module instantiated as an integrated unit or segmented into a Slave, or secondary, Transmitter Signal Receiver sub-module and an Adaptive Director Firmware sub-module may be integrated into, or attached to, a Master, or primary, Transmitter or may be implemented with a Slave, or secondary, Transmitter Signal Receiver sub-module integrated into, or attached to a Master, or primary, Transmitter and an Adaptive Director Firmware sub-module integrated into or attached to a Slave, or secondary, Transmitter. The Slave Receiver and Adaptive Director Firmware Module, for integrated implementations, or the Slave, or secondary, Transmitter Signal Receiver sub-module and the Adaptive Director Firmware sub-module for segmented implementations, captures and conditions signals delivered over a Slave-To-Master Communications Link and presents the conditioned bit stream to one side of the Master, or primary, Transmitter&#39;s Master/Slave Switch. The Master, or primary, Transmitter&#39;s bit stream is connected to the other side of the Master, or primary, Transmitter&#39;s Master/Slave Switch. In operation the Master, or primary, Transmitter establishes communication with the remote receiver over a Primary Communications Link with the Master/Slave Switch of the present invention in the ‘Master’ position. This is the normal or default position and the operator of the Master, or primary, Transmitter controls the remote device or appliance. At anytime the Slave, or secondary, Transmitter may be turned on and radiates its signal, containing the encoded representation of the Slave, or secondary, Transmitter&#39;s control sticks, levers and switches, over the Slave-To-Master Communications Link. Now, with the Master, or primary, Transmitter and the Slave, or secondary, Transmitter powered on, whenever the Master/Slave Switch is placed into the ‘Slave’ position the radiated signal from the Master, or primary, Transmitter will contain the encoded representations of the Slave, or secondary, Transmitter&#39;s control sticks, levers and switches as captured and conditioned by the Slave-To-Master Communications facility and the Adaptive Firmware of the present invention. In this way the present invention enables the remote device or appliance to be controlled by the operator of the Slave, or secondary, Transmitter. Returning the Master/Slave Switch of the present invention to the ‘Master’ positions transfers control of the remote device or appliance back to the operator of the Master, or primary, Transmitter. 
         [0007]    It is an object of the present invention to provide a wireless Slave-To-Master Communications Facility alternative to the current art requiring a hard wired interconnection between a Master, or primary, Transmitter and a Slave, or secondary, Transmitter for the purpose of transferring control of remote devices and/or appliances to trainee or guest operators. 
         [0008]    It is an object of the present invention to significantly enhance the ease-of-use and convenience of transferring control of remote devices or appliances to trainees or guests by Master, or primary, Transmitter operators. 
         [0009]    It is an object of the present invention to significantly improve the versatility of a facility for transferring control of remote devices or appliances to trainees or guests by Master, or primary, Transmitter operators. The present invention can be embodied to accommodate diverse base methods of coding, modulating, and/or multiplexing the conversion of control sticks, levers and switches positions into electrical signals and the decoding, demodulating, and/or de-multiplexing functions of de-conversion to effect remote device or appliance actions. 
         [0010]    It is an object of the present invention to provide a wireless Slave-To-Master Communications Facility alternative to the current art requiring a hard wired interconnection between a Master, or primary, Transmitter and a Slave, or secondary, Transmitter for the purpose of transferring control of remote devices or appliances to trainees or guests and which functions independent of Master, or primary, Transmitter radiation mode or carrier wave frequency. That is, the present invention is adaptive providing full Master/Slave functionality in systems utilizing radiation methods including, but not limited to:
   Amplitude Modulation on sub-sonic, sonic, infrared, radio, microwave, short wave, or ultra short wave fixed or spread spectrum carrier frequencies.   Frequency Modulation on sub-sonic, sonic, infrared light, ultraviolet light, visible light, radio, microwave, short wave, or ultra short wave fixed or spread spectrum carrier frequencies.
 
both base-band and side-band.

That is, the present invention is adaptive providing full Master/Slave functionality in systems utilizing encoding, modulating and/or multiplexing methods including, but not limited to:
   Pulse Code Modulation   Pulse Position Modulation   
 
         [0016]    It is an object of the present invention to provide a wireless Slave-To-Master Communications Facility alternative to the current art requiring a hard wired interconnection between a Master, or primary, Transmitter and a Slave, or secondary, Transmitter for the purpose of transferring control of remote devices or appliances to trainees or guests and which functions independent of Slave, or secondary, Transmitter encoding, modulating and/or multiplexing modes or carrier wave frequency. 
         [0017]    Broadly stated, the present invention is an apparatus comprising a programmable Slave Receiver and Adaptive Director Firmware Module, that may be instantiated as an integrated unit or segmented into a Slave, or secondary, Transmitter Signal Receiver sub-module and an Adaptive Director Firmware sub-module, which processes radiated signals emitted from a Slave, or secondary, Transmitter and propagated over a Slave-To-Master Communications Link. The Slave Receiver and Adaptive Director Firmware Module instantiated as an integrated unit or segmented into a Slave, or secondary, Transmitter Signal Receiver sub-module and an Adaptive Director Firmware sub-module may be integrated into, or attached to, a Master, or primary, Transmitter or may be implemented with a Slave, or secondary, Transmitter Signal Receiver sub-module integrated into, or attached to a Master, or primary, Transmitter and an Adaptive Director Firmware sub-module integrated into or attached to a Slave, or secondary, Transmitter. The Slave Receiver and Adaptive Director Firmware Module, for integrated implementations, or the Slave, or secondary, Transmitter Signal Receiver sub-module and the Adaptive Director Firmware sub-module for segmented implementations, processes and conditions signals delivered over a Slave-To-Master Communications Link and presents a conditioned bit stream to one side of the Master, or primary, Transmitter&#39;s Master/Slave Switch. The Master, or primary, Transmitter&#39;s bit stream is connected to the other side of the Master, or primary, Transmitter&#39;s Master/Slave Switch. When set in the ‘Master’ position The Master, or primary, Transmitter&#39;s bit stream is delivered to the Master, or primary, Transmitter&#39;s modulator. When set in the ‘Slave’ position, the conditioned bit stream provided from the Slave Receiver and Adaptive Director Firmware Module, for integrated implementations, or from either the Slave, or secondary, Transmitter Signal Receiver sub-module or Adaptive Director Firmware sub-module, for segmented implementations of the present invention is delivered to the Master, or primary, Transmitter&#39;s modulator. In either case the Master, or primary, Transmitter transmits the modulated signal over a Primary Communications Link.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0026]    Referring to  FIG. 1  a representative embodiment of the present invention is illustrated. In  FIG. 1  there is shown a front view of a representative embodiment of the present invention having a Master, or primary, Transmitter  1 , Master, or primary, Transmitter Power Switch  2 , Master Control Sticks, Levers and Switches  3 , a Primary Communications Link  4 , a Primary Receiver  5 , a series of De-multiplexed/Decoded Control Signals  6 , a series of Vehicle/Appliance Actuators  7 , a Slave, or secondary, Transmitter  8 , a Slave, or secondary, Transmitter Power Switch  9 , Slave Control Sticks, Levers and Switches  10 , a Slave-To-Master Communications Link  11 , a Slave Receiver and Adaptive Director Firmware Module  12  attached to the Master, or primary, Transmitter  1 , and a Master/Slave Switch  13 . 
         [0027]    Still referring to the representative embodiment of the present invention illustrated in  FIG. 1 , both the Master, or primary, Transmitter  1  and the Slave, or secondary, Transmitter  8  are powered on as the Master, or primary, Transmitter Power Switch  2  is in the ‘On’ position as is the Slave, or secondary, Transmitter Power Switch  9 . As the Master/Slave Switch  13  is in the ‘Master’ position the Master, or primary, Transmitter  1  is radiating the coded signal representations of the Master Control Sticks, Levers and Switches  3  over the Primary Communications Link  4 , and are being received and processed by the Primary Receiver  5  which decodes the composite received signal and separates it into distinct De-multiplexed/Decoded Control Signals  6  which are interpreted and executed by the Vehicle/Appliance Actuators  7  thereby imparting the Master, or primary, Transmitter  1  operator&#39;s directives into remote device or appliance actions. 
         [0028]    In more detail, still referring to the representative embodiment of the present invention of  FIG. 1 , the signal transmitted over the wireless Slave-to-Master Communications Link  11  is received by the Slave Receiver and Adaptive Director Firmware Module  12  attached to the Master, or primary, Transmitter  1  but is providing no influence over the signal transmitted by the Master, or primary, Transmitter  1  as the Master/Slave Switch  13  is in the ‘Master’ position and the Master, or primary, Transmitter&#39;s bit stream is flowing directly to the Master, or primary, Transmitter&#39;s  1  Modulator. When, however, the Master/Slave Switch  13  is placed in the ‘Slave’ position the Slave Receiver and Adaptive Director Firmware Module  12  receives and processes the wireless signal arriving over the Slave-to-Master Communications Link  11  and the resultant bit stream is delivered to the Master, or primary, Transmitter&#39;s  1  Modulator. In either case, i.e. when the Master/Slave Switch  13  is in the ‘Master’ position or in the ‘Slave’ position, the Master, or primary, Transmitter  1  propagates the bit stream provided to its modulator over the Primary Communications Link  4 . 
         [0029]    Still referring to the representative embodiment of the present invention of  FIG. 1  the processing and conditioning of the signal arriving over the Slave-to-Master Communications Link  11  by the Slave Receiver and Adaptive Director Firmware Module  12  is governed by logic embedded in the Slave Receiver and Adaptive Director Firmware Module  12  which condition the bit stream it receives according to parameters also embedded within the Slave Receiver and Adaptive Director Firmware Module  12  and/or switches/jumpers attached to the Slave Receiver and Adaptive Director Firmware Module  12 . By this means, control of the Vehicle/Appliance Actuators  7  can be transparently transferred to the operator of the Slave, or secondary, Transmitter  8  operator independent of transmission or signal encoding schemes employed by either the Master, or primary, Transmitter  1  or the Slave, or secondary, Transmitter  8 . 
         [0030]    Referring now to  FIG. 2  a front view of a first alternate embodiment of the present invention is illustrated having a Master, or primary, Transmitter  1 , Master, or primary, Transmitter Power Switch  2 , Master Control Sticks, Levers and Switches  3 , a Primary Communications Link  4 , a Primary Receiver  5 , a series of De-multiplexed/Decoded Control Signals  6 , a series of Vehicle/Appliance Actuators  7 , a Slave, or secondary, Transmitter  8 , a Slave, or secondary, Transmitter Power Switch  9 , Slave Control Sticks, Levers and Switches  10 , a Slave-To-Master Communications Link  11 , a Slave Receiver and Adaptive Director Firmware Module  12 , a Conventional ‘Buddy Box’ Socket Compatible Plug  15  affixed to the Slave Receiver and Adaptive Director Firmware Module  12  and a Master/Slave Switch  13 . In this instance the Master, or primary, Transmitter  1  is configured with a Conventional ‘Buddy Box’ Socket  14  usable to plug in one end of the conventional Slave, or secondary, Transmitter to Master, or primary, Transmitter hard wired connection. In this first alternate embodiment of the present invention the Slave Receiver and Adaptive Director Firmware Module  12  is extended with a Conventional ‘Buddy Box’ Socket Compatible Plug  15  thereby providing a direct wireless replacement for the Conventional ‘Buddy Box’ hard wired connection. By this means the functionality of the present invention is extended to existing varieties of Master, or primary, Transmitters  1  already in service which have a Conventional ‘Buddy Box’ Socket  14 . This first alternate embodiment of the present invention illustrated in  FIG. 2  is a wireless one-for-one replacement for the Conventional ‘Buddy Box’ hard wired connection system of sharing control of remote devices and appliances. The Slave Receiver and Adaptive Director Firmware Module  12  of this first alternate embodiment of the present invention receives, demodulates, and conditions the signal arriving on the Slave-To-Master Communications Link  11  and makes it available to the Master, or primary, Transmitter  1 . Various Conventional ‘Buddy Box’ Socket  14  configurations are produced by the major manufactures of remote control systems and each may be readily accommodated by a correspondingly tailored Conventional ‘Buddy Box’ Socket Compatible Plug  15 . 
         [0031]    In more detail, still referring first alternate embodiment of the present invention of  FIG. 2 , Transmitter  1  is delivering the Master, or primary, Transmitter&#39;s bit stream directly to the Master, or primary, Transmitter&#39;s  1  Modulator. The Slave Receiver and Adaptive Director Firmware Module  12  is plugged into Transmitter&#39;s  1  by means of the attached Conventional ‘Buddy Box’ Socket Compatible Plug  15  and the signal transmitted over the wireless Slave-to-Master Communications Link  11  is received and conditioned by the Slave Receiver and Adaptive Director Firmware Module  12  attached to the Master, or primary, Transmitter  1  but is providing no influence over the signal transmitted by the Master as the Master/Slave Switch  13  is in the ‘Master’ position. When, however, the Master/Slave Switch  13  is placed in the ‘Slave’ position the Slave Receiver and Adaptive Director Firmware Module  12  receives and processes the wireless signal arriving over the Slave-to-Master Communications Link  11  and delivers the resultant bit stream to the Master, or primary, Transmitter&#39;s  1  Modulator. In either case, i.e. whether the Master/Slave Switch  13  is in the ‘Master’ position or in the ‘Slave’ position, the Master, or primary, Transmitter  1  propagates the bit stream provided to its modulator over the Primary Communications Link  4 . This first alternate embodiment of the present invention of  FIG. 2  provides wireless functionality equivalent to the Conventional ‘Buddy Box’ hard-wired system of instantiating transferable control of a remote vehicle or appliance. 
         [0032]    Still referring to the first alternate embodiment of the present invention of  FIG. 2 , the processing and conditioning of the signal arriving over the Slave-to-Master Communications Link  11  by the Slave Receiver and Adaptive Director Firmware Module  12  is governed by logic embedded in the Slave Receiver and Adaptive Director Firmware Module  12  which condition the bit stream it receives according to parameters also embedded within the Slave Receiver and Adaptive Director Firmware Module  12  and/or switches/jumpers attached to the Slave Receiver and Adaptive Director Firmware Module  12 . By this means, control of the Vehicle/Appliance Actuators  7  can be transparently transferred to the operator of the Slave, or secondary, Transmitter  8  operator independent of transmission or signal encoding schemes employed by either the Master, or primary, Transmitter  1  or the Slave, or secondary, Transmitter  8 . 
         [0033]    Referring now to  FIG. 3  a high-level block diagram is shown of the operation of a Master, or primary, Transmitter  1  configured with a Slave Receiver and Adaptive Director Firmware Module  12  as illustrated in the representative embodiment of the present invention of  FIG. 1 . Slave, or secondary, Transmitter Signal Receiver  30  sub-module is receiving the Slave-to-Master Communications Link  11  signal. The Slave, or secondary, Transmitter Signal Receiver  30  sub-module demodulates the Communications Link  11  signal and passes the resultant Slave Bit Stream to the Adaptive Director Firmware  31 . The Adaptive Director Firmware  31  performs all bit translations and modulation modifications indicated by the parameters stored in nonvolatile memory and/or attached switches/jumpers and submits the resultant bit stream to the Master/Slave Switch  13 . The bit stream generated within the Master, or primary, Transmitter  1  is also submitted to the Master/Slave Switch  13  by Master Tx Bit Stream  40 . When the Master/Slave Switch  13  is in the ‘Master’ position the bit stream from Master Tx Bit Stream  40  is directed to Master Tx Modulator  41  for propagation via the Master Tx Transmitter  42  over Primary Communications Link  4 . When the Master/Slave Switch  13  is in the ‘Slave’ position the bit stream from the Adaptive Director Firmware  31  is directed to Master Tx Modulator  41  for propagation via the Master Tx Transmitter  42  over Primary Communications Link  4 . 
         [0034]    Referring now to  FIG. 4  a programming flow chart for the Slave Receiver and Adaptive Director Firmware Module  12  for the representative embodiment of the present invention of  FIG. 1  is illustrated. At initiation Query Programming Power  71  is executed and, as the programming power is not present, the Start  50  logic is invoked which accesses parameters stored in nonvolatile memory and/or attached switches/jumpers and initializes program variables. The stored parameters and attached switches/jumpers, if any, characterize the working environment including, but not limited to, method of bit stream encoding, number of channels, need and specifics for address and/or data translation of the ‘Slave’ bit stream, and need and specifics for modification of the modulation method. 
         [0035]    Still referring to  FIG. 4  the Slave, or secondary, Transmitter Signal Receiver  30  sub-module is receiving the incoming signal over the Slave-to-Master Communications Link  11 , demodulates it and sends the ‘Slave’ data bit stream to Query Stream Modification Required  51 . The receiver modules of certain remote devices currently in use discriminate among arriving signals by the contents of one or more fixed position bits in the signal stream. To accommodate these devices and maintain the desired selectivity, bit translation may be needed; if so it will be denoted by parameters stored within the Adaptive Director Firmware Module  31  and/or switches/jumpers attached to the Adaptive Director Firmware Module  31 . If, using these stored parameters and/or attached switches/jumpers, Query Stream Modification Required  51  determines that either address or data stream bit translation is required Query Address or Data Translation Required  52  is called and it calls Translate Address and/or Data Bits  54  if analysis of the internal stored parameters and/or attached switches/jumpers so indicate; if not, processing continues with Query Modify Modulation Method  53 . If called, Translate Address and/or Data Bits  54  performs the required bit stream translation and manipulation according to code installed in the program memory of the Adaptive Director Firmware  31  which interprets the internal stored parameters installed into the data memory of the Adaptive Director Firmware  31  and/or switches/jumpers attached to the Adaptive Director Firmware Module  31  and passes the modified stream to Query Modify Modulation Method  53 . Various modulation methods are employed by existing remote control systems e.g. Pulse-Position-Modulation (‘PPM’) and Pulse-Code-Modulation (‘PCM’) and the modulation method of the Master, or primary, Transmitter  1  of  FIG. 1  may be different from the modulation method of the Slave, or secondary, Transmitter  8  of  FIG. 1 . To accommodate these differences Query Modify Modulation Method  53  accesses internal stored parameters and/or attached switches/jumpers to determine if the modulation method of the Slave, or secondary, Transmitter  8  of  FIG. 1  must be converted to the modulation method of the Master, or primary, Transmitter  1  of  FIG. 1 . If not, i.e. the modulation methods of both the Slave, or secondary, Transmitter  8  of  FIG. 1  and the Master, or primary, Transmitter  1  of  FIG. 1  are the same, no modification is needed and Query Modify Modulation Method  53  passes the bit stream directly to the Master/Slave Switch  13 . If, on the other hand, Query Modify Modulation Method  53  determines that modulation method modification is required the bit stream is forwarded to Modify Modulation Method  55  to re-configure the bit stream to the correct modulation format according to code installed in the program memory of the Adaptive Director Firmware  31  which interprets the internal stored parameters installed into the data memory of the Adaptive Director Firmware  31  and/or switches/jumpers attached to the Adaptive Director Firmware Module  31 . The bit stream then passes to the Master/Slave Switch  13 . If the Master/Slave Switch  13  is in the ‘Slave’ position the Master/Slave Switch  13  connects the bit stream produced by the Adaptive Director Firmware  31  to the Master Tx Modulator  41  and finally to the Master Tx Transmitter  42  which propagates the stream over the Primary Communications Link  11 . If, instead, the Master/Slave Switch  13  is in the ‘Master’ position the Master/Slave Switch  13  connects the Master Tx Bit Stream  40  to the Master Tx Modulator  41  and finally to the Master Tx Transmitter  42  which propagates the stream over the Primary Communications Link  11 . 
         [0036]    Referring now to  FIG. 5  a generalized block diagram illustrating one method for how the Adapter Director Firmware of the wireless transferable control system of the present invention may be tailored to suit varying environments. At initiation Query Programming Power  71  is executed and, as the programming power is present, the programming mode of the Adaptive Director Firmware  31  sub-module is entered and Query PC Request Received  72  is called which retrieves a request string from Personal Computer  80  if one is available. The request string consists of a command value, an address value, and a data value. The Query PC Request Received  72  acknowledges the request causing Personal Computer  80  to enter a loop awaiting result notification from Adapter Director Firmware  31  sub-module. Extract Command and Address  73  copies the command and address values from the request string into local variables and calls Query Read Program Memory Command  74  which calls Execute Read Program Memory Command  78  if the command value, the command value copied into a local variable by Extract Command and Address  73 , is a read program memory request. Execute Read Program Memory Command  78  issues a read program memory command at the designated address value, the address value copied into a local variable by Extract Command and Address  73 , of the Adaptive Director Firmware  31  sub-module&#39;s program memory. Query Read Program Memory Error  82  sends the value read in a Read Program Memory Successful message to Personal Computer  80  via Send Read Program Memory Value To PC  90  completing the request if no error has occurred. If an unrecoverable read error has occurred Report Read Program Memory Error To PC  86  is called which completes the read program memory request by sending a Read Program Memory Error notification message to Personal Computer  80 . If the command value, the command value copied into a local variable by Extract Command and Address  73 , is not a read program memory Query Write Program Memory Command  75  is called and it calls Extract Value For Program Memory  79  if the command value, the command value copied into a local variable by Extract Command and Address  73 , is a write program memory. Extract Value For Program Memory  79  extracts the data value from the request string and calls Execute Write Program Memory Command  83  which attempts to write the data value to the address value, the address value copied into a local variable by Extract Command and Address  73 , of the Adaptive Director Firmware  31  sub-module&#39;s program memory, and calls Query Write Program Memory Error  87  to determine success or failure. If Execute Write Program Memory Command  83  completed without error Query Write Program Memory Error  87  sends a Request Successful notification message to Personal Computer  80 . If unsuccessful, Report Write Program Memory Error To PC  91  is called which completes the write program memory request by sending a Write Program Memory Error notification message to Personal Computer  80 . If the command value, the command value copied into a local variable by Extract Command and Address  73 , is not a write program memory Query Write Program Memory Command  75  calls Query Read Data Memory Command  76  which calls Execute Read Data Memory Command  80  if the command value, the command value copied into a local variable by Extract Command and Address  73 , is a read data memory request. Execute Read Data Command  80  issues a read data memory command at the designated address value of the Adaptive Director Firmware  31  sub-module&#39;s data memory. Query Read Data Memory Error  84  sends the value read in a Read Data Memory Successful message to Personal Computer  80  via Send Read Data Memory Value To PC  92  completing the request if no error has occurred. If an unrecoverable read error has occurred Report Read Data Memory Error To PC  88  is called which completes the read data memory request by sending a Read Data Memory Error notification message to Personal Computer  80 . If the command value, the command value copied into a local variable by Extract Command and Address  73 , is not a read data memory Query Write Data Memory Command  77  is called and it calls Extract Value For Data Memory  81  if the command value, the command value copied into a local variable by Extract Command and Address  73 , is a write data memory. Extract Value For Data Memory  81  extracts the data value from the request string and calls Execute Write Data Memory Command  85  which attempts to write the data value to the address value, the address value copied into a local variable by Extract Command and Address  73 , and calls Query Write Data Memory Error  89  to determine success or failure. If Execute Write Data Memory Command  85  completed without error Query Write Data Memory Error  89  sends a Request Successful notification message to Personal Computer  80 . If unsuccessful, Report Write Data Memory Error To PC  93  is called which completes the write program memory request by sending a Write Program Memory Error notification message to Personal Computer  80 . As documented and explained, the Adaptive Director Firmware  31  sub-module may be configured with programmable program memory and/or programmable data memory. The programmable data memory of the Adaptive Director Firmware  31  sub-module can by loaded by the means shown in  FIG. 5 , and described herein, with revisable parameters and, at execution time, these stored parameters can be accessed and, in conjunction with attached switches/jumpers that may also be provided, utilized by the logic coded and loaded into the program memory of the Adaptive Director Firmware  31  sub-module by the means shown in  FIG. 5 , and described herein, to enable the Wireless Transferable Control System of the present invention to provide the desired functionality with any combination of modulation scheme or bit protocol used by Master, or primary, Transmitters  1  and Slave, or secondary, Transmitters  8  of the representative embodiment of the present invention of  FIG. 1  or any alternative embodiment of the present invention such as the alternative representative embodiment of the present invention of  FIG. 2 . This process applies equivalently and consistently to Adaptive Director Firmware of the present invention implemented as an integrated Slave Receiver and Adaptive Director Firmware Module or as implemented as a segmented Adaptive Director Firmware sub-module. 
         [0037]    Referring now to  FIG. 6  a second alternate embodiment of the present invention is illustrated showing how the Slave Receiver and Adaptive Director Firmware Module  12  of the wireless transferable control system of the present invention may be dynamically tailored to accommodate varying environments is illustrated. Various switches and/or jumpers may be connected, and their contact positions sensed by, the Slave Receiver and Adaptive Director Firmware Module  12 . Instructions coded into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  can then utilize the acquired switch position information to selectively override the intent of parameters stored in the data memory of the Slave Receiver and Adaptive Director Firmware Module  12 . In  FIG. 6 , Three Position Modulation Method Switch  110  is shown in the ‘NI’, or ‘No Impact’, position therefore the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  will be interpreted and processed by the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12 . If however, Three Position Modulation Method Switch  110  is set to the ‘PPM’ (Pulse Position Modulation) position the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  will be overridden causing the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  to Modify the Modulation Method to ‘PPM’ for the conditioned Slave Bit Stream accordingly. If Three Position Modulation Method Switch  110  is set to the ‘PCM’ (Pulse Code Modulation) position the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  will be overridden causing the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  to Modify the Modulation Method to ‘PCM’ for the conditioned Slave Bit Stream accordingly. Similarly, Four Position Channel Select Switch  111  will override any existing Address Translation parameters stored in the internal data memory of the Slave Receiver and Adaptive Director Firmware Module  12  unless set to the ‘NI’, or ‘No Impact’, position. A common Slave Bit Stream format assigns two specific bits to designate the channel for the stream; e.g. 00=Channel A, 01=Channel B, 10=Channel C. This scheme allows several transmitters of the same genre to operate concurrently without interfering one to the other as their associated remote receivers can discriminate among the multiple broadcasts based on the contents of the two channel bits and respond only to the bit stream of its channel. Thus, for instance, if Four Position Channel Select Switch  111  is set to the ‘A’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  and will cause the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  to modify the address bits of the Slave Bit Stream to designate Channel ‘A’. If Four Position Channel Select Switch  111  is set to the ‘B’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  and will cause the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  to modify the address bits of the Slave Bit Stream to designate Channel ‘B’. If Four Position Channel Select Switch  111  is set to the ‘C’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  and will cause the logic programmed into the program memory of the Slave Receiver and Adaptive Director Firmware Module  12  to modify the address bits of the Slave Bit Stream to designate Channel ‘C’. If Four Position Channel Select Switch  111  is set to the ‘NI’ position Translate Address parameters programmed into the internal data memory, if any, of the Slave Receiver and Adaptive Director Firmware Module  12  and will solely control weather or not the address bits of the Slave Bit Stream will be altered. Any and all parameters characterizing a bit stream can be controlled by programming the internal data memory and program memory of the Slave Receiver and Adaptive Director Firmware Module  12  of  FIG. 6  for integrated unit implementations, or the Adaptive Director Firmware  31  sub-module of  FIG. 3 , for segmented implementations of the present invention and any and all can be dynamically overridden in field use by attaching to the Slave Receiver and Adaptive Director Firmware Module  12  of  FIG. 6  for integrated unit implementations, or the Adaptive Director Firmware  31  sub-module of  FIG. 3 , for segmented implementations of the present invention corresponding switches and/or jumpers as exemplified by the Three Position Modulation Method Switch  110  and Four Position Channel Select Switch  111  examples of  FIG. 6 . 
         [0038]    Referring now to  FIG. 7  a front view of a third alternate embodiment of the present invention is illustrated having a Master, or primary, Transmitter  1 , Master, or primary, Transmitter Power Switch  2 , Master Control Sticks, Levers and Switches  3 , a Primary Communications Link  4 , a Slave, or secondary, Transmitter  8 , a Slave, or secondary, Transmitter Power Switch  9 , Slave Control Sticks, Levers and Switches  10 , a Slave-To-Master Communications Link  11 , a Master/Slave Switch  13 , a Conventional ‘Buddy Box’ Socket Compatible Plug  15  affixed to the Slave, or secondary, Transmitter Signal Receiver  30  sub-module, an Adaptive Director Firmware  31  sub-module, a Three Position Modulation Method Switch  110 , and a Four Position Channel Select Switch  111 . Again in this embodiment the Master, or primary, Transmitter  1  is configured with a Conventional ‘Buddy Box’ Socket  14  used to plug in one end of the conventional Slave, or secondary, Transmitter to Master, or primary, Transmitter hard wired connection. In this third alternate embodiment of the present invention the Slave, or secondary, Transmitter Signal Receiver  30  sub-module and Adaptive Director Firmware  31  sub-modules of the Slave Receiver and Adaptive Director Firmware Module  12  of  FIG. 1  are distributed and transposed and the Slave, or secondary, Transmitter Signal Receiver  30  sub-module is extended with a Conventional ‘Buddy Box’ Socket Compatible Plug  15 . In this embodiment the conditioning of the Slave bit stream is performed by the Adaptive Director Firmware  31  sub-module that is integrated or attached to the Slave, or secondary, Transmitter  8 . The Slave, or secondary, Transmitter  8  propagates the conditioned bit stream over the Slave-to-Master Communications Link  11  and the Slave, or secondary, Transmitter Signal Receiver  30  sub-module demodulates the signal it receives from the Slave-to-Master Communications Link  11 . The output of the Slave, or secondary, Transmitter Signal Receiver  30  sub-module is connected to the ‘Slave’ terminal of the Master/Slave Switch  13  via the Conventional ‘Buddy Box’ Socket Compatible Plug  15  and Conventional ‘Buddy Box’ Socket  14 . The processing and conditioning of the signal delivered to the Slave-to-Master Communications Link  11  by the Adaptive Director Firmware  31  sub-module is governed by logic embedded in the Adaptive Director Firmware  31  sub-module which conditions the Slave, or secondary, Transmitter  8  bit stream according to parameters also embedded within the Adaptive Director Firmware  31  and/or switches/jumpers attached to the Adaptive Director Firmware  31 . Code installed into the program memory of the Adaptive Director Firmware  31  conditions the Slave, or secondary, Transmitter  8  bit according to interrogation and interpretation of parameters installed into the data memory of the Adaptive Director Firmware  31  and switches and/or jumpers connected to the Adaptive Director Firmware  31  sub-module. In this third alternate embodiment of the present invention illustrated in  FIG. 7  dynamic modification switches Three Position Modulation Method Switch  110  and Four Position Channel Select Switch  111  are attached to the Slave, or secondary, Transmitter  8  and are connected to the Adaptive Director Firmware  31  sub-module embedded within Slave, or secondary, Transmitter  8 . In  FIG. 7 , Three Position Modulation Method Switch  110  is shown in the ‘NI’, or ‘No Impact’, position therefore the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module will be interpreted and processed by the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module. If however, Three Position Modulation Method Switch  110  is set to the ‘PPM’ (Pulse Position Modulation) position the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module will be overridden causing the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module to Modify the Modulation Method to ‘PPM’ for the conditioned Slave Bit Stream. If Three Position Modulation Method Switch  110  is set to the ‘PCM’ (Pulse Code Modulation) position the Modify Modulation Method parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module will be overridden causing the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module to Modify the Modulation Method to ‘PCM’ for the conditioned Slave Bit Stream. Similarly, Four Position Channel Select Switch  111  will override any existing Address Translation parameters stored in the internal data memory of the Adaptive Director Firmware  31  sub-module unless set to the ‘NI’, or ‘No Impact’, position. If Four Position Channel Select Switch  111  is set to the ‘A’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module and will cause the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module to modify the address bits of the Slave Bit Stream to designate Channel ‘A’. If Four Position Channel Select Switch  111  is set to the ‘B’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module and will cause the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module to modify the address bits of the Slave Bit Stream to designate Channel ‘B’. If Four Position Channel Select Switch  111  is set to the ‘C’ position this will override the Translate Address parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module and will cause the logic programmed into the program memory of the Adaptive Director Firmware  31  sub-module to modify the address bits of the Slave Bit Stream to designate Channel ‘C’. If Four Position Channel Select Switch  111  is set to the ‘NI’ position Translate Address parameters programmed into the internal data memory, if any, of the Adaptive Director Firmware  31  sub-module and will solely control weather or not the address bits of the Slave Bit Stream will be altered and, if so, how they should be modified. Any and all parameters characterizing a bit stream can be controlled by programming the internal data memory and program memory of the Adaptive Director Firmware  31  sub-module of the present invention and any and all can be dynamically overridden in field use by attaching corresponding switches and/or jumpers as exemplified by the Three Position Modulation Method Switch  110  and Four Position Channel Select Switch  111  examples of  FIG. 7 . Thus a bit stream, originating in the Slave, or secondary, Transmitter  8 , that is fully compatible with the modulation method and protocol of the Master Transmitter  1  can be generated and provided to the ‘Slave’ terminal of the Master/Slave Switch  13  via the Conventional ‘Buddy Box’ Socket Compatible Plug  15  and Conventional ‘Buddy Box’ Socket  14 . By these means this third alternate embodiment of the present invention of  FIG. 7  provides a wireless functionality equivalent to the conventional hard-wired system of instantiating transferable control of a remote vehicle or appliance independent of transmission or signal encoding schemes employed by either the Master, or primary, Transmitter  1  or the Slave, or secondary, Transmitter  8 . The method and process for programming the program and/or data memory of the Adapter Director Firmware  31  sub-module illustrated in  FIG. 5  and described above applies equivalently and consistently to this third alternate embodiment of the present invention of  FIG. 7 .

       ADVANTAGES OF THE PRESENT INVENTION 
       [0048]    The advantages of the present invention include, without limitation, the great ease-of-use improvement of the Wireless Transferable Control System of the present invention in comparison to the cumbersome hard-wired transferable control system of the current art. Additionally, the unique programmability attributes of the Wireless Transferable Control System of the present invention provide compatibility among all Master, or primary, Transmitter and Slave, or secondary, Transmitters used for remote control—this functionality and flexibility is not available at all in the current art. The current art demands that the Master, or primary, and Slave, or secondary, Transmitters utilize similar bit stream format and modulation method and requires matching cable, plugs, and jacks. The programmability functionality of the present invention removes all of these restrictions allowing two or more similar or diverse transmitters to share, on-demand and as-desired, the control of remote devices and appliances independent of bit stream format or modulation method. The Wireless Transferable Control System of the present invention provides a quantum leap forward in flexibility, adaptability, and freedom of maneuverability for sharing remote controlled devices and appliances.
