Abstract

A simple, secure and cost effective method to program authorized transmitters into the memory of a controller, such as that in a garage door opener, which does not require a learn switch. An already-authorized transmitter is used to prime the receiver to add a new transmitter identification code to its list. The sequence is to press the button of any transmitter that is already recognized by the controller, within a short time window (e.g., 3 seconds) to press the button of the new transmitter that is to be added, and within another short time window (e.g., 3 seconds) press again the button of the transmitter used in the first step.

Claims

1. A remote control system having a receiver and one or more transmitters, each transmitter transmitting a respective identification code and the receiver having a list of identification codes associated with authorized transmitters, the receiver being operable to compare a received identification code to the codes on its list, the improvement by which the receiver is primed to add to its list a received new identification code upon prior receipt of an identification code that is already on its list.

2. A remote control system in accordance with claim 1 wherein a received new identification code is added to the receiver list only if it is received within a set time interval after the receiver is first primed to add a received new identification code to its list.

3. A remote control system in accordance with claim 2 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

4. A remote control system in accordance with claim 2 wherein if the receiver list is empty then a received new identification code is added to the list even without the receiver being primed by an identification code that was previously on the list.

5. A remote control system in accordance with claim 1 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

6. A remote control system in accordance with claim 5 wherein a received new identification code is added to the receiver list only if it and the subsequent identification code that was previously on its list are both received within a set time interval following receipt of the identification code that primed the receiver to add a new identification code to its list.

7. A remote control system in accordance with claim 1 wherein if the receiver list is empty then a received new identification code is added to the list even without the receiver being primed by an identification code that was previously on the list.

8. A remote control system comprising a receiver and one or more transmitters, each transmitter transmitting a respective identification code and the receiver having a list of identification codes associated with authorized transmitters, the receiver including means operable to compare a received identification code to the codes on its list, and means for controlling the receiver to add to its list a received new identification code upon associated receipt of an identification code that is already on its list.

9. A remote control system in accordance with claim 8 wherein a received new identification code is added to the receiver list only if it is received within a set time interval of receipt of an identification code that is already on its list.

10. A remote control system in accordance with claim 9 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

11. A remote control system in accordance with claim 9 wherein if the receiver list is empty then a received new identification code is added to the list even without receipt of an identification code that was previously on the list.

12. A remote control system in accordance with claim 8 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

13. A remote control system in accordance with claim 12 wherein a received new identification code is added to the receiver list only if it and an identification code that was previously on its list are both received within a set time interval following receipt of an identification code that controlled the receiver to add a new identification code to its list.

14. A remote control system in accordance with claim 8 wherein if the receiver list is empty then a received new identification code is added to the list even without receipt of an identification code that was previously on the list.

26. A method in accordance with claim 8 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

27. A remote control system in accordance with claim 26 wherein a received new identification code is added to the receiver list only if it and the subsequent identification code that was previously on its list are both received within a set time interval following receipt of the identification code that primed the receiver to add a new identification code to its list.

15. A method of operating a remote control system having a receiver and one or more transmitters, each transmitter transmitting a respective identification code and the receiver having a list of identification codes associated with authorized transmitters, the receiver being operable to compare a received identification code to the codes on its list, the improvement by which the receiver adds to its list a received new identification code if it is accompanied by receipt of an identification code that is already on its list.

16. A method of operating a remote control system in accordance with claim 15 wherein a received new identification code is added to the receiver list only if it is received within a set time interval of the receipt of an identification code already on the receiver list.

17. A method of operating a remote control system in accordance with claim 16 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was already on its list.

18. A method of operating a remote control system in accordance with claim 16 wherein if the receiver list is empty then a received new identification code is added to the list even without receipt of an identification code that was already on the list.

19. A method of operating a remote control system in accordance with claim 15 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was already on its list.

20. A method of operating a remote control system in accordance with claim 19 wherein a received new identification code is added to the receiver list only if it and a subsequent identification code that was already on the receiver list are both received within a set time interval following receipt of an identification code that was already on the receiver list.

21. A method of operating a remote control system in accordance with claim 15 wherein if the receiver list is empty then a received new identification code is added to the list even without receipt of an identification code that was already on the list.

22. A method of operating a remote control system comprising the steps of providing a receiver and one or more transmitters, each transmitter transmitting a respective identification code and the receiver having a list of identification codes associated with authorized transmitters, the receiver operating to compare a received identification code to the codes on its list, and priming the receiver to add to its list a received new identification code upon receipt of an identification code that is already on its list.

23. A method in accordance with claim 22 wherein a received new identification code is added to the receiver list only if it is received within a set time interval after the receiver is first primed to add a received new identification code to its list.

24. A method in accordance with claim 23 wherein a received new identification code is added to the receiver list only if after its receipt the receiver receives an identification code that was previously on its list.

25. A method in accordance with claim 23 wherein if the receiver list is empty then a received new identification code is added to the list even without the receiver being primed by an identification code that was previously on the list.
