Abstract

In a method embodiment, a method for controlling power includes receiving a user input to control the on/off state of one or more electronic devices plugged into a plurality of respective power sockets in a power strip. The method further includes determining, by the power strip, an electrical characteristic of respective ones of the plurality of power sockets. Additionally, the method includes toggling the on/off state of the one or more of the plugged in electronic devices based on the determination.

Claims

1. A method of controlling power comprising:

receiving a user input to control the on/off state of one or more electronic devices plugged into a plurality of respective power sockets in a power strip;

determining, by the power strip, an electrical characteristic of the respective ones of the plurality of power sockets; and

toggling the on/off state of the one or more of the plugged in electronic devices based on the determination.

2. The method of claim 1, wherein determining an electrical characteristic comprises determining whether current drawn through respective ones of the plurality of power sockets exceeds respective thresholds.

3. The method of claim 2, and further comprising setting the respective thresholds by turning on respective ones of the one or more electronic devices and storing respective current levels corresponding to respective on states of the one or more electronic devices.

4. The method of claim 1, and further comprising:

remotely communicating the user input to the power strip;

remotely communicating, by the power strip, a signal based on the determination of the electrical chrematistic of the respective ones of the plurality of power sockets; and

wherein toggling the on/off state of the one or more of the plugged in electronic devices based on the determination comprises remotely communicating one or more signals to the respective plugged in electronic devices.

5. The method of claim 4, wherein remotely communicating comprises communicating using wireless technology selected from the group consisting of:

blue-tooth;

infrared; and

radio wave.

6. The method of claim 1, and further comprising:

storing a macro that sets the on/off state of the plugged in devices;

wherein receiving user input comprises receiving a request to execute the macro; and

wherein toggling the on/off state of the one or more of the plugged in electronic devices based on the determination further comprises toggling the on/off state according to the macro.

7. The method of claim 1, and further comprising:

mapping each of the plugged in electronic devices to respective ones of the plurality of power sockets by;

selecting each of the plugged in electronic devices by toggling the on/off state one at a time;

sensing a change in the electrical characteristic of respective ones of the plurality of power sockets after each selection; and

storing an association of the selected electronic device with the respective ones of the plurality power sockets.

8. The method of claim 1, wherein receiving a user input further comprises exchanging authentication keys.

9. A power control system comprising:

a power strip comprising;

a plurality of power sockets;

a plurality of sensors each responsive to an electrical characteristic of respective ones of the plurality of power sockets;

a receiver operable to receive a remote input; and

one or more processors, each processor in communication with the receiver and one or more of the one or more sensors, each processor operable to receive the remote input from the receiver and, in response, interpret one or more of the electrical characteristics and communicate the interpretation to a transmitter.

10. The power control system of claim 9, wherein each sensor comprises a current sensor in communication with respective ones of the plurality of power sockets, and control circuitry coupled to each current sensor for determining the current drawn through the respective ones of the plurality of power sockets.

11. The power system of claim 10, wherein each processor is further operable to determine whether the current drawn through the respective ones of the plurality of power sockets is in excess of respectively determined thresholds.

12. The power system of claim 11, wherein each processor is further operable to set the respectively determined thresholds, at least in part, by comparing a high current level and a low current level of the respective ones of the plurality of power sockets.

13. The power control system of claim 9, and further comprising:

a controller comprising;

a user interface operable to receive a user input;

a transmitter operable to transmit, based on the user input, the remote input to the receiver of the power strip;

a receiver operable to receive the interpretations transmitted by the transmitter of the power strip; and

wherein the transmitter is further operable to transmit, based at least partly on the interpretations received from the transmitter of the power strip, one or more power state control signals.

14. The power control system of claim 13, and further comprising one or more devices electrically coupled to respective ones of the plurality of power sockets;

and

wherein the one or more power state control signals are operable to control the on/off state of at least a subset of the one or more devices.

15. The power control system of claim 14, wherein the controller is further operable to store a macro indicating the desired on/off states of at least a subset of the one or more devices;

and

wherein execution of the macro depends at least in part on the interpretations transmitted by the transmitter of the power strip.

16. The power control system of claim 13, wherein the power strip and the controller are operable to transmit and receive by wireless communication selected from the group consisting of:

blue-tooth;

infrared; and

radio wave.

17. The power control system of claim 13, wherein the power strip and the controller are further operable to transmit and receive authentication codes enabling execution of the user input.

18. The power control system of claim 13, wherein the devices are further operable to transmit and receive authentication codes enabling execution of the control signals.

19. A method of controlling power to electronic devices, comprising:

receiving a user input to control the on/off state of a plurality of electronic devices plugged into a plurality of respective power sockets in a power strip;

mapping each of the plugged in electronic devices to respective ones of the plurality of power sockets;

storing, by the power strip, a respective on-state current threshold associated with each plugged in device;

determining the on/off state of each of the electronic devices by interpreting whether the current levels associated with each plugged in device exceeds the respective on-state current threshold; and

toggling the on/off state of the one or more of the plugged in electronic devices based on the determination.

20. The method of claim 19, wherein toggling the on/of state comprises transmitting wireless communication.
