Abstract

Method and apparatus for system control includes inputs for an input device which may take the form of switches or sensors. Input device states are related to identification keys. The identification keys are communicated wirelessly or through hard-wired means to a system.

Claims

1. Method for system control comprising;

relating an active device state of an input device to an identification key comprising ;

transitioning the device state of the input device from a previous device state to the active device state based on a device state input respective to the active device state that is input to the input device, wherein the previous device state is based on a previous device state input respective to the previous device state that was previously input to the input device; and

selecting a unique identification key corresponding to the transitioned to active device state, each possible device state representing a possible setting of the input device and corresponding to a distinct unique identification key containing data comprising an input for controlling an apparatus of a system to transition to a system setting corresponding to the respective device state;

communicating the unique identification key to a system controller; and

in response to receiving the communicated unique identification key at the system controller from the input device, utilizing the system controller to control the apparatus of the system to transition from a previous system setting based on a previously selected identification key corresponding to the previous device state to an active system setting based on the presently communicated unique identification key corresponding to the active device state, wherein the apparatus of the system comprises one of an actuator and an additional controller of the system.

2. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises encoding a plurality of switch inputs to address a memory structure.

3. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises decoding a plurality of switch inputs to address a memory structure.

4. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises addressing a memory structure with a plurality of switch inputs.

5. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises multiplexing a memory structure in accordance with a plurality of switch inputs.

6. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises converting an analog sensor signal to a digital address and referencing a memory structure with the address.

7. The method for system control as claimed in claim 1 wherein relating the active device state to the identification key further comprises referencing a memory structure based on a digital sensor signal.

8. The method for system control as claimed in claim 1 wherein communicating the unique identification key comprises transmitting the unique identification key using wireless communication links.

9. The method for system control as claimed in claim 1 wherein communicating the unique identification key comprises transmitting the unique identification key using hardwired communication links.

10. Control apparatus comprising:

an input device having a plurality of device states, each device state representing a possible setting of the input device and corresponding to a distinct identification key containing data comprising an input for controlling an apparatus of a system to transition to a system setting respective to the device state, the input device receiving a device state input respective to a current device state for transitioning from a previous device state to the current device state, wherein the previous device state is based on a previous device state input respective to the previous device state that was previously received by the input device;

an identification key selection apparatus for selecting identification keys corresponding to the transitioned to current device state;

a communication device for communicating selected identification keys to a controller from the input device; and

the controller responsive to the communicated identification keys to control the apparatus of the system to transition from a previous system setting based on a previously selected identification key corresponding to the previous device state to a current system setting based on the communicated selected identification keys, wherein the apparatus of the system comprises one of an actuator and an additional controller.

11. The control apparatus as claimed in claim 10 wherein the input device comprises a switch.

12. The control apparatus as claimed in claim 10 wherein the input device comprises a sensor.

13. The control apparatus as claimed in claim 10 wherein the identification key selection apparatus comprises a radio frequency identification chip.

14. The control apparatus as claimed in claim 10 wherein the identification key selection apparatus comprises a memory apparatus and means for addressing the memory apparatus based on current device states.

15. The control apparatus as claimed in claim 10 wherein the communication device comprises a radio frequency identification chip.

16. The control apparatus as claimed in claim 10 wherein the communication device comprises wireless communication apparatus.

17. The control apparatus as claimed in claim 10 wherein the communication device comprises hardwired communication apparatus.

18. The control apparatus as claimed in claim 15 wherein the communication apparatus comprises hardwired communication apparatus.

19. Control apparatus comprising:

an input device relating a plurality of device states, each device state representing a possible setting of the input device, to a plurality of identification keys, each identification key corresponding to a respective one of the device states and containing data comprising an input for controlling a system to transition to a system setting, the input device receiving a device state input respective to a present device state for transitioning from a previous device state to the present device state, wherein the previous device state is based on a previous device state input respective to the previous device state that was previously received by the input device;

selection apparatus coupled to the input device, the selection apparatus effective to interpret the device states of the input device and to provide at least one identification key uniquely corresponding to at least one respective present device state of the input device;

communication apparatus to convey the at least one identification key provided by the selection apparatus to a system controller; and

wherein said system controller is effective to produce a response based on the identification keys conveyed thereto for controlling the system to transition from a previous system setting based on at least one previously selected identification key corresponding to the previous device state to a present system setting based on the communicated at least one identification key uniquely corresponding to the at least one respective present device state of the input device, wherein the system comprises one of an actuator and an additional controller.

20. The control apparatus as claimed in claim 19 wherein the selection apparatus comprises a radio frequency identification chip.

21. The control apparatus as claimed in claim 19 wherein the selection apparatus comprises a memory apparatus and means for addressing the memory apparatus based on current states of the input device.

22. The control apparatus as claimed in claim 19 wherein the communication apparatus comprises a radio frequency identification chip.

23. The control apparatus as claimed in claim 19 wherein the communication apparatus comprises wireless communication apparatus.
