Wall plate adapter for coupling home network control signals to AC power wiring
First Claim
1. A wall plate adapter for an electrical outlet, comprising:
- a plate with at least one receptacle face;
wherein the at least one receptacle face overlays at least one receptacle of the electrical outlet when the plate is secured over the electrical outlet;
the at least one receptacle face having slots aligned with slots of the at least one receptacle so that prongs of a plug can be plugged into the slots of the at least one receptacle after passing through the slots of the at least one receptacle face;
at least one electrical contact carried by the wall plate and located so that the at least one electrical contact touches at least one of the prongs of the plug when the plug is plugged into the slots of the at least one receptacle; and
circuitry for communicating, via the at least one electrical contact, with AC power wiring of the at least one receptacle, when the plug is plugged into the slots of the at least one receptacle, the circuitry comprising at least one transmitter for transmitting a signal for use in a network via the AC power wiring and at least one receiver for receiving a command from a network via the AC power wiring.

Abstract
A wall plate adapter for coupling home network control signals to AC power wiring, where the wall plate adapter includes built-in signaling circuitry. The wall plate adapter includes a plate with a receptacle face with slots that are aligned with slots of an underlying AC receptacle. When prongs of a plug are inserted into the slots of the wall plate adapter, they touch contacts that are located in the slots of the receptacle face. The contacts are, in turn, coupled to the signaling circuitry, which may be located in an enlarged region of the wall plate. The signaling circuitry is only coupled to the AC power when a plug is inserted. The plug may be coupled to a transformer and a network device.

10. A wall plate adapter for an electrical outlet, comprising:
-
a plate with at least first and second receptacle faces; wherein the first and second receptacle faces overlay first and second receptacles, respectively, of the electrical outlet when the plate is secured over the electrical outlet; the first receptacle face having slots aligned with slots of the first receptacle so that prongs of a first plug can be plugged into the slots of the first receptacle after passing through the slots of the first receptacle face; the second receptacle face having slots aligned with slots of the second receptacle so that prongs of a second plug can be plugged into the slots of the second receptacle after passing through the slots of the second receptacle face; at least one electrical contact carried by the wall plate and located so that the at least one electrical contact touches at least one of the prongs of the first plug when the first plug is plugged into the slots of the first receptacle; and circuitry for communicating, via the at least one electrical contact, with AC power wiring of the first receptacle of the electrical outlet when the plug is plugged into the slots of the first receptacle, the circuitry comprising at least one transmitter for transmitting a signal for use in a network via the AC power wiring and at least one receiver for receiving a command from a network via the AC power wiring. - View Dependent Claims (11, 12)

13. A system for use in a network which uses AC power wiring of a structure, comprising:
-
a device in the network; a transformer for receiving electrical power from an electrical receptacle that is coupled to the AC power wiring, and providing transformed electrical power to the device; and a wall plate for the electrical receptacle; wherein;
the wall plate includes a communication module that is electrically coupled tothe transformer and the electrical receptacle when the transformer is plugged into the electrical receptacle using prongs of a plug; and the device includes at least one transmitter and at least one receiver for communicating with the communication module in the wall plate via the prongs of the plug.
