Abstract

A remotely controllable power switch of an appliance and a method of employing a remotely controllable power switch of an appliance to control the overall load that an electric power distribution network bears. The method may include a method of employing a remotely controllable power switch of an appliance to compute the rate that a particular customer pays for electric power. In one embodiment, the remotely controllable power switch of an appliance includes: (1) a switching device coupled between an input and an output of the remotely controllable power switch of an appliance and (2) communication circuitry coupled to the switching device, addressable only by class and configured to receive a turn-off signal and turn off the switching device in response thereto.

Claims

1. A remotely controllable power switch of an appliance, comprising:

a switching device coupled between an input and an output of said remotely controllable power switch of an appliance; and

communication circuitry controlling said switching device, and being configured to receive a turn-off signal through an electric power distribution line and to turn off said switching device in response thereto.

2. The remotely controllable power switch of an appliance as recited in claim 1 wherein said communication circuitry is further configured to receive a turn-on signal and turn on said switching device in response thereto.

3. The remotely controllable power switch of an appliance as recited in claim 1 wherein said input includes a plug and said output includes a receptacle.

4. The remotely controllable power switch of an appliance as recited in claim 3 wherein said switching device is a first switching device and said output is a first output and said remotely controllable power switch of an appliance further comprises a second switching device coupled between said input and a second output, said communication circuitry further coupled to said second switching device.

5. The remotely controllable power switch of an appliance as recited in claim 1 further comprising further outputs coupled directly to said input.

6. The remotely controllable power switch of an appliance as recited in claim 1 wherein said input includes a plug and said output includes a transformer.

7. A method of employing a, comprising:

transmitting a turn-off signal to remotely controllable power switches of a class of appliances through an electric power distribution network such that power of an electric power distribution network is interrupted to the appliances of the class by the remotely controllable power switches; and

thereby interrupting power only to appliances coupled to an electric power distribution network through the class of remotely controllable appliance power switches; and

simultaneously providing power to remaining appliances through said electric power distribution network.

8. The method as recited in claim 7 further comprising:

transmitting a turn-on signal to said class of remotely controllable power switches of appliances to restore power to said appliances via said electric power distribution network.

9. The method as recited in claim 7 wherein ones of said some of the remotely controllable power switches of appliances are incorporated in a selected one of:

an appliance power module,

a power strip, and

a plug-in charger.

10. The method as recited in claim 7 wherein said class is a first class and said method further comprises transmitting a turn-off signal to a second class of appliances.

11. The method as recited in claim 7 further comprising:

transmitting a current draw signal from one of said appliances to the network; and

computing an electric power rate for a customer corresponding to said one of said appliances based at least in part on said current draw signal.

12. The method as recited in claim 11 wherein said current draw signal indicates only whether said remotely controllable power switch of said one of said appliances is turned on or turned off.

13. The method as recited in claim 12 wherein said computing comprises computing said electric power rate based on one of:

a day of a week that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on,

a time of a day that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on, and

an amount of time that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on.

14. The method as recited in claim 11 wherein said current draw signal indicates an amount of current drawn through said remotely controllable power switch of an appliance.

15. The method as recited in claim 14 wherein said computing comprises computing said electric power rate based on an amount of current drawn through said remotely controllable power switch of an appliance.

16. The method as recited in claim 15 wherein said computing further comprises further computing said electric power rate based on one of:

a day of a week that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on,

a time of a day that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on, and

an amount of time that said current draw signal indicates that said remotely controllable power switch of an appliance is turned on.
