Abstract

A vehicle convenience system comprising a wireless transmitter, having at least one switch therein, for communicating multiple channel commands to an expander, the expander responsive to activation of the transmitter and said expander having at least one expander output responsive to the channel commands received from the transmitter; the expander outputs being programmable to at least one user selectable mode.

Claims

1. A system having at least one output channel, said system comprising:

a transmitter, having at least one switch, at least one channel command issued from said transmitter to a controller responsive to activation of said transmitter;

said controller, having at least one expander trigger output responsive to said at least one channel command received from said transmitter, said at least one expander trigger output triggering an expander having at least one expander output; and

said at least one expander output is programmable to at least one user selectable mode.

2. The device of claim 1 further comprising an off-mode.

3. The device of claim 1 further comprising a latch-reset-with-ignition-mode.

4. The device of claim 1 further comprising a latch-mode.

5. The device of claim 1 further comprising a timed-mode.

6. The device of claim 1 further comprising a memory.

7. The device of claim 1 further comprising a memory allowing said expander to operate at least one last operated said at least one expander output.

8. The device of claim 1 further including an audio free response.

9. The device of claim 1 further including an audio response.

10. The device of claim 1 further including an audio and visual response.

11. The device of claim 1 further including a memory to store at least one of a state or a function of said device.

12. The device of claim 1 further including a visual response.

13. The device of claim 1 further including a visual free response.

14. The device of claim 1 further comprising a memory-mode.

15. The device of claim 1 further comprising a validity-mode.

16. The device of claim 1 further comprising a pulse-mode.

17. The device of claim 1 further including a visual free and audio free response.

34. The device of claim 12 further comprising a memory allowing said expander to operate at least one last operated said at least one expander output.

18. A system comprising:

a transmitter, having at least one switch, at least one channel command issued from said transmitter to an expander responsive to activation of said transmitter;

said expander having at least one expander output; and

said at least one expander output is programmable to at least one user selectable mode.

19. The device of claim 18 further comprising an off-mode.

20. The device of claim 18 further comprising a latch-reset-with-ignition-mode.

21. The device of claim 18 further comprising a latch mode.

22. The device of claim 18 further comprising a timed-mode.

23. The device of claim 18 further comprising a memory.

24. The device of claim 18 further including an audio free response.

25. The device of claim 18 further including an audio response.

26. The device of claim 18 further including an audio and visual response.

27. The device of claim 18 further including a memory to store at least one of a state or a function of said device.

28. The device of claim 18 further including a visual response.

29. The device of claim 18 further including a visual free response.

30. The device of claim 18 further including a visual free and audio free response.

31. The device of claim 18 further comprising a memory-mode.

32. The device of claim 18 further comprising a validity-mode.

33. The device of claim 18 further comprising a pulse-mode.
