Abstract

A controller for a device transmitting commands across one or more communication channels. Each such channel may employ a separate medium, such as radio waves and infrared light. The controller may transmit two separate signals to a device, where one signal is sent via radio waves and the other by infrared light. One signal may correspond to a group identifier and the other to an operating command to be carried out by the device. The device may receive both signals and, if the device belongs to a group corresponding to the group identifier, it may execute the operating command. Alternatively, the group identifier may be replaced by a wake command and the device may execute the operating command only if the wake command is received.

Claims

1. A method for operating a device, comprising the operations of:

receiving a first communications signal having a first characteristic;

in response to the first communications signal, configuring a device into a first operative state;

receiving a second communications signal having a second characteristic, the second characteristic different than the first characteristic, and prior to receiving the first communications signal, the device is inoperative to receive the second signal;

determining at least one command provided in the second communications signal; and

executing the at least one command.

2. The method of claim 1, wherein:

the first communications signal is one of an infrared signal and a radio-frequency signal; and

the second communications signal is the other of the infrared signal and the radio-frequency signal.

4. The method of claim 1, further comprising:

in response to receiving the first communications signal, activating a receiver attuned to the characteristic of the second communications signal.

5. The method of claim 4, further comprising:

in the event the at least one command is a grouping command, determining if the first and second communications signals are received simultaneously;

if the first and second communications signals are received simultaneously, executing the grouping command; and

otherwise, ignoring the grouping command.

6. The method of claim 4, further comprising the operation of deactivating the receiver attuned to the frequency of the second communications signal after a set time from receipt of the second communications signal.

7. The method of claim 6, further comprising:

deactivating a first receiver operative to receive the first communications signal after a second set time from receipt of the first communications signal; and

periodically activating the first receiver after deactivating it.

8. The method of claim 1, wherein:

the first communications signal includes a first beam pattern; and

the second communications signal includes a second beam pattern different from the first beam pattern.

3. (canceled)

9. An apparatus for remotely controlling a device, comprising:

a first transmitter operative to transmit a first communications signal with a first characteristic;

a second transmitter operative to transmit a second communications signal with a second characteristic;

a processor operative to control the first and second transmitters;

a group command module operative to transmit a grouping command to the device via one of the first and second transmitters, the group command module controlled by the processor;

an operation command module operative to transmit an operation command to the device via one of the first and second transmitters, the operation command module controlled by the processor; and

a wake command module operative to transmit a wake command to the device via one of the first and second transmitters, the wake command module controlled by the processor.

10. The apparatus of claim 9, wherein the processor controls at least one of the group command module, operation command module, and wake command module in response to an input from a user interface operably connected to the processor.

11. The apparatus of claim 9, wherein the wake command is identical to at least one of the grouping command and operation command.

12. The apparatus of claim 9, wherein:

the first transmitter is a radio frequency transmitter; and

the second transmitter is an infrared transmitter.

13. The apparatus of claim 12, wherein the first and second transmitters may transmit simultaneously.

14. The apparatus of claim 13, wherein:

the radio frequency transmitter transmits the first communications signal at a first frequency corresponding to a radio frequency and further transmits a third communications signal at a third frequency;

the third frequency is likewise a radio frequency; and

the third frequency is different from the first frequency.

15. The apparatus of claim 14, wherein the first communications signal and third communications signal are transmitted substantially simultaneously.

16. A device operative to respond to a first and second remote signal, comprising:

a processor;

a first receiver operative to receive a first communications signal and convey first information associated with the first communications signal to the processor;

a second receiver operative to receive a second communications signal, but not prior to said first receiver receiving said first communication signal, and convey second information associated with the second communications signal to the processor; and

application circuitry operative to control at least a portion of the device in response to a command from the processor, the command based at least partially on one of the first information and second information.

17. The device of claim 16, wherein the device is a covering for an architectural opening.

18. The device of claim 17, wherein:

the first communications signal is an infrared signal; and

the second communications signal is a radio-frequency signal.

19. The device of claim 18, wherein:

one of the first information and second information includes a group identifier and an operating command;

the processor is operative to determine if the device belongs to a group corresponding to the group identifier; and

the processor is further operative to operate the application circuitry in accordance with the operating command in the event the device belongs to the group corresponding to the group identifier.

20. The device of claim 18, wherein the second receiver is inoperative until the first communications signal is received by the first receiver.

21. The device of claim 20, wherein the first receiver cycles periodically from a sleep state to a wake state.

22. The device of claim 18, wherein:

one of the first information and second information contains an instruction to place the device into a group;

the processor is operative to determine if the first communications signal and the second communications signal are received substantially simultaneously;

the processor is further operative to place the device into the group only if the first and second communications signals are received substantially simultaneously.

23. The device of claim 18, wherein:

one of the first information and second information contains an instruction to remove the device from a group;

the processor is operative to determine if the first communications signal and the second communications signal are received substantially simultaneously;

the processor is further operative to remove the device from the group only if the first and second communications signals are received substantially simultaneously.
