Abstract

A control system selectively controls the operation of at least one lamp and at least one garage door opener. The control system includes a control module. The control module includes connectors adapted to be coupled to at least one lamp through household AC power conductors. The control module also includes terminals adapted to be connected to a garage door opener mechanism. A circuit positioned in the control module receives and identifies radio frequency signals, stores control information associated with a plurality of received signals from a remote control in a training mode and outputs control signals for communication over the AC power line and the garage door mechanism in accordance with the stored control signals when one of said remote control signals is received in an operating mode. The control module also includes a selector used to select garage door and/or light control operations to be associated with a signal received by the control module in a training mode.

2. The system as defined in claim 1, wherein said circuit means is adapted to learn a plurality of different frequency control signals, each having a different carrier frequency and signaling format.

3. The system as defined in claim 1, further including at least one lamp receptacle module adapted to be inserted into a lamp receptacle and receive a light bulb, said lamp receptacle module adapted to communicate with said control module through the AC power conductors.

4. The system as defined in claim 1, further including at least one outlet module adapted to be coupled to AC power outlets, said outlet module adapted to communicate with said control module through said AC power conductors.

5. The system as defined in claim 4, wherein said circuit means is adapted to be programmed to actuate the garage door opener mechanism and the lights responsive to a first control signal, to control only the garage door opener in response to a second control signal, and to control only the lights in response to third control signal.

6. The system as defined in claim 1, further including a timer selector switch coupled to said circuit means, said circuit means responsive to said timer selector switch for selecting a time delay before a lights off control signal is transmitted following transmission of a lights on control signal.

7. The system as defined in claim 6, wherein said timer selector switch has a first timer off position, a second short time position, and a third longer time position, said circuit means automatically outputting a lights off signal a first predetermined time period after emitting a lights on signal when said timer selector switch is in said second position, said circuit means automatically outputting a lights off signal a second predetermined time period after emitting a lights off signal when said timer selector switch is in said third position.

8. A system for controlling at least one outlet module coupled to household AC power conductors responsive to a control signal from a remote control, comprising:
