Abstract

A wireless transmitter associated with a switched electrical connection and a receiver therefor, adapted for connection in an electrical path between the source of power and a load, enables the load to be controlled by the switch originally used to control the switched electrical connection. The communication between the transmitter and receiver may be realized only when power is applied or removed from the switched connection, or, alternatively, this communication may be carried out on a per-cycle basis, enabling a phase-delay type of control over the relocated load, including dimming of the relocated load without requiring modification to a previously installed dimmer switch. The signal radiated by the transmitter may be of acoustic or electromagnetic origin, though IR transmissions are used in the preferred embodiment. The transmitter module includes means for making electrical contact to a switched electrical connection, and means for transmitting a wireless signal in response to the application of electrical Dower to the switched electrical connection, and the receiver module includes means for making electrical contact to a source of electrical power, means for making contact to an electrical load, and means for routing electrical power from the source to the load in response to the signal transmitted by the transmitter module. Exposed wires, plug- and socket-type connections may be utilized as alternatives depending upon physical implementation.

Claims

1. Electrical switched-load relocation apparatus adapted for use with an electrical connection, controlled by a switch, a source of A.C. electrical power, and an electrical load, comprising:

a wireless transmitter module in electrical communication with the electrical connection and the source of A.C. electrical power, the transmitter module being operative to radiate a remote-control signal on a per-cycle basis when the electrical power is applied to the connection through the switch; and

a wireless receiver module physically separate from the wireless transmitter module and disposed in an electrical path between the source of A.C. electrical power and the electrical load, the receiver being operative to route power from the source to the load on a per-cycle basis in response to the remote-control signal radiated by the transmitter, thereby enabling the switch to control a relocated load on a delayed-phase basis.

2. The electrical switched-load relocation apparatus as see forth in claim 1, wherein the signal radiated by the transmitter is an infrared signal.

3. The electrical switched-load relocation apparatus as set forth in claim 1, wherein the signal radiated by the transmitter is an RF signal.

4. The electrical switched-load relocation apparatus as set forth in claim 1, wherein the signal radiated by the transmitter is an acoustical signal.

5. The electrical switched-load relocation apparatus as set forth in claim 1 including a switched electrical connection associated with an electrical outlet located in the ceiling of a room.

6. The electrical switched-load relocation apparatus as set forth in claim 1 including a switched electrical connection associated with a wall outlet of a room.

7. A system for relocating a switched electrical connection, comprising:

a transmitter module, including;

a threaded base for making electrical contact to a switched electrical socket of the type configured to receive a light bulb with threaded base, and

means other than the light bulb for transmitting a wireless signal in response to the application of electrical power to the switched electrical socket; and

a receiver module, including;

means for making electrical contact to a source of electrical power,

means for making contact to an electrical load, and

means for routing electrical power from the source to the load in response to the signal transmitted by the transmitter module.

8. The system as see forth in claim 7, wherein the transmitter module further includes means for making electrical contact to an electrical load which receives power in response to the application of electrical power to the switched electrical connection.

9. The system as set forth in claim 7 wherein the means for making electrical contact to a source of electrical power includes a set of exposed wires adapted for connection to a corresponding set of exposed wires.

10. The system as set forth in claim 7, wherein the means for making electrical contact to a source of electrical power includes a plug to be inserted into an electrical outlet.

11. The system as set forth in claim 7, wherein the means for making electrical contact to a source of electrical power includes a threaded base to be inserted into an electrical socket.

12. The system as set forth in claim 7, wherein the means for making contact to an electrical load includes an electrical outlet into which a load having a plug may be inserted.

13. The system as set forth in claim 7, wherein the means for making contact to an electrical load includes an electrical socket into which a load having a threaded base may be installed.

14. The system as set forth in claim 7, wherein the means for transmitting a wireless signal in response to the application of electrical power to the switched electrical connection and the means for routing electrical power from the source to the load in response to the wireless signal both function on a per-cycle basis in conjunction with AC power, thereby permitting remote phase-angle control.
