Abstract

Methods and devices for sharing energy between devices are provided. For example, an electronic device (100) can include a control circuit (504) and an energy storage device (301) operable with the control circuit. The electronic device can include a power interface (201) operable with the energy storage device and a user interface, such as a control button (303), that is operable with the control circuit. The control circuit can determine another device (601) is coupled to the power interface, and can detect user input occurring at the user interface for at least a predetermined duration (701). In response, the control circuit can cause the energy storage device to deliver a portion of energy stored therein to the another device through the power interface.

Claims

1. A device, comprising:

a control circuit;

an energy storage device operable with the control circuit;

a power interface operable with the energy storage device; and

a user interface operable with the control circuit;

the control circuit to;

determine another device coupled to the power interface;

detect user input occurring continuously at the user interface for at least a predetermined duration; and

in response the user input occurring continuously for the predetermined duration cause the energy storage device to deliver a portion of energy stored therein to the another device through the power interface.

2. The device of claim 1, the user interface comprising a control button, the user input comprising pressing the control button.

3. The device of claim 2, the control button comprising a multifunction control button, the control circuit to execute a function different from causing the energy storage device to deliver the portion of energy to the another device when the control button is pressed less than the predetermined duration.

4. The device of claim 2, the predetermined duration at least three seconds.

5. The device of claim 2, the device further comprising a touch sensitive display disposed along a first major face of the device, the control button disposed on a second major face of the device disposed opposite the first major face.

6. The device of claim 1, further comprising an energy capacity indicator to present a first visible indication prior to the user input occurring continuously for the predetermined duration and a second visible indication after the user input occurring continuously for the predetermined duration.

7. The device of claim 6, the first visible indication identifying an amount of stored energy in the energy storage device, the second visible indication both the amount of stored energy in the energy storage device and indicia of power delivery to the another device through the power interface.

8. The device of claim 7, the energy capacity indicator comprising a plurality of lights, the first visible indication comprising illuminating at least some of the plurality of lights for different durations, the second visible indication comprising flashing one or more of the plurality of lights simultaneously.

9. The device of claim 1, the portion of energy defined by a predetermined current from the energy storage device through the power interface for a predetermined time.

10. The device of claim 1, the portion of energy defined by a predetermined percentage of a state of charge of the energy storage device prior to the user input occurring continuously for the predetermined duration.

11. The device of claim 1, the control circuit to cause the energy storage device to deliver the portion of energy stored therein to the another device through the power interface in accordance to one or more user defined rules.

12. The device of claim 11, the one or more user defined rules identifying the another device.

13. The device of claim 1, the power interface stowable within a housing of the device when not coupled to the another device.

14. The device of claim 1, the power interface comprising a wireless interface.

15. A method, comprising:

detecting, with a control circuit, a device coupled to a power interface;

receiving, from a user input, continuous actuation of the user input for at least a predetermined duration; and

after receiving the continuous actuation of the user input for the at least a predetermined duration, sharing energy from an energy storage device with the device by delivering current through the power interface.

16. The method of claim 15, the sharing comprising sharing only a portion of the energy from the energy storage device with the device.

17. The method of claim 16, further comprising receiving user input defining the portion.

18. The method of claim 15, further comprising receiving user input defining one or more whether the device is permitted to share energy with the energy storage device, when to terminate the sharing, or combinations thereof.

19. A system, comprising:

a first device comprising;

a power interface;

an energy storage device operable with the power interface;

a control circuit operable with the energy storage device; and

a user input device operable with the control circuit; and

a second device coupled to the power interface;

the control circuit to detect actuation of the user input device for at least a predetermined duration to cause the energy storage device to deliver a portion of its stored energy to the second device through the power interface.

20. The system of claim 19, the control circuit to determine whether the second device is permitted to receive the portion prior to causing the energy storage device to deliver the portion.
