Abstract

A reconfigurable remote control transmitter can be used with a plurality of remotely controlled products, each of which is normally controlled with one or more signals from an associated remote control transmitter. The reconfigurable transmitter has a plurality of input keys and operates either in a Learn mode in which it may store indications of signals generated by the remote control transmitter from one or more of the products or a Run mode in which it selectively transmits stored signals in response to one or more keyed inputs. During the Learn mode a selected sequence of operations to be performed by one or more of the products in response to a first selected key sequence may be stored and during the Run mode stored signals are transmitted in a predetermined order in response to the performance of the selected key sequence to cause the selected sequence of operations to be performed.

The transmitter may also include one or more timers settable to a selected data and time, which may be utilized to control the transmitting of stored signals or signal sequences.

Finally, a means may be provided which is operative during the Learn mode for indicating that the signal being received by the transmitter from a remote transmitter is of proper strength to permit an indication thereof to be correctly stored.

Claims

1. In a reconfigurable remote control transmitter for use with a plurality of remotely controlled products, each of which is normally controlled with one or more signals from an associated remote control transmitter, said reconfigurable transmitter having a plurality of input keys, having a learn mode in which it may store indications of signals generated by the remote control transmitter for one or more of said products and having a run mode in which it selectively transmits stored signals in response to one or more keyed inputs;

the improvement comprising;

first means operative during said learn mode for storing a selected sequence of operations to be performed by one or more of said products in response to a first selected input key sequence; and

second means operative during said run mode for transmitting stored signals in a predetermined order in response to the performance of a second selected input key sequence to cause the selected sequence of operations to be performed.

2. A transmitter as claimed in claim 1 wherein said first means is operative in response to the operation of a preset key followed by a key to become a program key.

3. A transmitter as claimed in claim 2 wherein said second means is operative to transmit the stored signals for performing a selected sequence of operations in response to the operation of said preset key followed by the operation of the program key for the selected operation sequence.

4. A transmitter as claimed in claim 1 wherein said first means includes means for selecting the input key sequence for a sequence of operations to be performed;

and

means for sequentially storing an indication of each operation to be performed, said storing being performed for the operations in the sequence in which the operations are to be performed.

5. A transmitter as claimed in claim 4 wherein said first means includes means operative after the storing of an indication for an operation for enabling the storing of an indication for the next operation.

6. A transmitter as claimed in claim 4 including means for storing one or more "waits" of predetermined duration in said sequence to cause a predetermined delay between the performance of two of the operations.

7. A transmitter as claimed in claim 1 wherein said first means includes means for storing one or more "waits" of predetermined duration in said sequence to cause a predetermined delay between the performance of two of the operations.

8. A transmitter as claimed in claim 1 wherein said first selected input key sequence and said second selected input key sequence are the same.

9. A transmitter as claimed in claim 1 including at least one timer means settable to a selected day and time;

and wherein said second means is operative either in response to the selected input key sequence or in response to a correspondence between the day and time set in said timer means and the current day and time.

10. A transmitter as claimed in claim 9 wherein there are a plurality of said timer means;

and including

means for setting said timer means to days and times at which selected sequences of operations are to be performed by said products and at which such sequences are to be terminated; and

means responsive to a correspondence between the day and time set in a timer means and the current day and time for transmitting the stored signals required to cause the corresponding sequence of operations to be performed or terminated.

11. A transmitter as claimed in claim 10 including means for enabling and disabling each of said timer means.

12. A transmitter as claimed in claim 9 including clock means for generating the current day and time;

and

means operative for normally displaying said day and time.

13. A transmitter as claimed in claim 1 including clock means for generating the current day and time;

and

means operative for normally displaying said day and time.

14. A transmitter as claimed in claim 1 including means operative during the learn mode for indicating if the signal being received by the transmitter from the remote transmitter for a product is of proper strength to permit an indication thereof to be correctly stored.

15. A transmitter as claimed in claim 14 wherein said means for indicating provides a visual indication.

16. A transmitter as claimed in claim 1 wherein said transmitter is battery powered;

wherein said first means includes a RAM in which said indications and sequences are stored which RAM is erased when power is lost; and

including means for maintaining power to said RAM for a limit period in the absence of battery power.

17. A transmitter as claimed in claim 16 wherein said means for maintaining includes a capacitor which is charged when said RAM is being powered by the battery and discharges to maintain power to the RAM in the absence of battery power.

18. In a reconfigurable remote control transmitter for use with a plurality of remotely controlled products, each of which is normally controlled with one or more signals from an associated remote control transmitter, said reconfigurable transmitter having a plurality of input keys, having a learn mode in which it may store indications of signals generated by the remote control transmitter for one or more of said products and having a run mode in which it selectively transmits stored signals in response to one or more keyed inputs, the improvement comprising:

means operative during the learn mode for detecting the strength of the signal being received by the transmitter from the remote transmitter for a product; and

means for indicating if the detected signal is of proper strength to permit an indication thereof to be correctly stored.

19. A transmitter as claimed in claim 18 wherein said means for indicating provides a visual indication.

20. In a reconfigurable remote control transmitter for use with a plurality of remotely controlled products, each of which is normally controlled with one or more signals from an associated remote control transmitter, said reconfigurable transmitter having a plurality of input keys, having a learn mode in which it may store indications of signals generated by the remote control transmitter for one or more of said products and having a run mode in which it selectively transmits stored signals in response to one or more keyed inputs;

an improved method of operation comprising the steps of;

storing during said learn mode a selected sequence of operations to be performed by one or more of said products in response to a first selected input key sequence; and

transmitting stored signals in a predetermined order in response to the performance of a second selected input key sequence during said run mode to cause the selected sequence of operations to be performed.

21. A method as claimed in claim 20 including the steps of selecting the input key sequence for a sequence of operations to be performed;

sequentially storing an indication of each operation to be performed, said storing being performed for the operations in the sequence in which the operations are to be performed.

22. A method as claimed in claim 21 including the step, performed after the storing of an indicator for an operation, of enabling the storing of an indication for the next operation.

23. A method as claimed in claim 20 wherein said first selected input key sequence and said second selected input key sequence are the same.

24. A method as claimed in claim 20 including at least one timer means settable to a selected day and time;
