Abstract

A system and method to open and/or close a garage door enables a receiving unit to activate a door opening and/or closing operator mechanism in response to receiving a signal. The transmitting unit transmits a signal to the receiving unit in response to a pulsed light signal.

Claims

1-11. -11. (canceled)

12. An external interface to automatically open and or close a door in response to a pulsed light signal having a predetermined characteristic, a motor coupled to the door for moving the door between an open position and a closed position covering an opening, a controller controlling operation of the motor in response to received command signals, the external interface comprising:

a transmitting unit for generating and transmitting command signals to move the door to the open position;

at least one detector for detecting the pulsed light signal;

a detector interface, for stimulating said transmitting unit to generate and transmit command signals to move the door to the open position, in response to the pulsed light signal;

a programmable interface coupled to said detector interface wherein the predetermined characteristic of the pulsed light signal for said detector interface can be programmed;

wherein when said detector detects the pulsed light signal having the predetermined characteristic said detector interface stimulates said transmitting unit to generate and transmit said command signals to move the door to the open position.

13. The external interface as recited in claim 12 wherein said transmitting unit further comprises a wireless transmitter for transmitting said command signals.

14. The external interface as recited in claim 12 wherein said detector interface is responsive to a predetermined sequence of the pulsed light signal.

15. The external interface as recited in claim 12 wherein said detector interface is responsive to a predetermined duration of the pulsed light signal.

16. The external interface as recited in claim 12 wherein said detector interface is responsive to a predetermined sequence and a predetermined duration of the pulsed light signal.

17. The external interface as recited in claim 12 wherein said programmable interface further comprises jumpers for programming the predetermined characteristic of the pulsed light signal.

18. The external interface as recited in claim 12 wherein said programmable interface further comprises DIP switches for programming the predetermined characteristic of the pulsed light signal.

19. The external interface as recited in claim 12 wherein said programmable interface further comprises digital means for programming the predetermined characteristic of the pulsed light signal.

20. The external interface as recited in claim 12 further comprising an independent battery power source.

21. The external interface as recited in claim 12 wherein said transmitting unit generates and transmits a coded signal.

22. The external interface as recited in claim 12 wherein said detector interface is responsive as a function of time.

23. The external interface as recited in claim 12 wherein said at least one detector is a plurality of detectors.

24. The external interface as recited in claim 19 wherein said programmable interface further means to learn the predetermined characteristic of the pulsed light signal when said programmable interface is in a learn mode.

25. An system to automatically open and or close a door in response to a pulsed light signal having a predetermined characteristic, a motor coupled to the door for moving the door between an open position and a closed position covering an opening, a controller controlling operation of the motor in response to received command signals, the external interface comprising:

a transmitting unit for generating and transmitting command signals to move the door to the open position;

at least one detector for detecting the pulsed light signal;

a detector interface, for stimulating said transmitting unit to generate and transmit command signals to move the door to the open position, in response to the pulsed light signal;

a programmable interface coupled to said detector interface wherein the predetermined characteristic of the pulsed light signal for said detector interface can be programmed;

wherein when said detector detects the pulsed light signal having the predetermined characteristic said detector interface stimulates said transmitting unit to generate and transmit said command signals to move the door to the open position.

26. The system as recited in claim 25 wherein said transmitting unit further comprises a wireless transmitter for transmitting said command signals, said transmitting united mounted on the door.

27. The system as recited in claim 25 wherein said detector interface is responsive to a predetermined sequence of the pulsed light signal.

28. The system as recited in claim 25 wherein said programmable interface further comprises digital means for programming the predetermined characteristic of the pulsed light signal.

29. The system as recited in claim 25 wherein said detector interface is responsive as a function of time.

30. The system as recited in claim 25 wherein said at least one detector is a plurality of detectors.

31. The system as recited in claim 28 wherein said programmable interface further means to learn the predetermined characteristic of the pulsed light signal when said programmable interface is in a learn mode.

26-1. The system as recited in claim 25 wherein said detector interface is responsive to a predetermined duration of the pulsed light signal.
