Abstract

Disclosed are devices and methods for regulating providing a charge via a charge receiving port of one device, the one device coupled to another device having a charge providing port. In one embodiment, the ports can be coupled by a cable. In another embodiment, the ports can be coupled wirelessly. The charge delivering device may regulate a charge providing process, controlled by a charge regulating controller of the charge providing device and based, for example, upon predetermined criteria. A charge regulating controller can disable the charging process, monitor the charge depletion rate, or the charging process may be based upon user established criteria. A charge regulating controller of the other device can regulate the charge accepting process. Each device may take on both roles, that is providing charge and receiving charge.

Claims

1. An electronic device, comprising:

a controller;

a power source coupled to the controller;

a first port configured to accept a first connection configured to provide a charge to another device;

a second port configured to accept a second connection configured to receive a charge; and

a charge regulating controller coupled to the controller and configured to regulate a charge via the first port based upon predetermined criteria.

2. The device of claim 1, further comprising:

a memory coupled to the controller;

a charge level module stored in memory and configured to establish a threshold value for the amount of charge of the power source above which the device will provide charge via the first port as a predetermined criterion; and

a disabling module stored in memory and configured to disable providing charge via the first port when charge of the power source is at least one of equal to and below the threshold value for the amount of charge of the power source.

3. The device of claim 1, further comprising:

a memory coupled to the controller;

a depletion rate module stored in memory and configured to establish a depletion rate at which the device will provide charge via the first port when the device is drawing power from the power source at a predetermined rate as a predetermined criterion; and

a disabling module stored in memory and configured to adjust the depletion rate for providing charge via the first port when the device is drawing power from the power source at the predetermined rate.

4. The device of claim 1, further comprising:

a user interface coupled to the controller;

a memory coupled to the controller; and

a user interface module stored in memory and configured to establish at least one user defined predetermined criterion via the user interface to adjust at least one of magnitude, duration and availability of the charge the device will provide via the first port as a predetermined criterion,

wherein the charge regulating controller is further configured to adjust providing charge via the first port based upon at least one user defined predetermined criterion.

5. The device of claim 1, wherein the first port is a USB port.

6. The device of claim 1, wherein the second port is a USB port.

7. The device of claim 1, further comprising:

a memory coupled to the controller; and

a device state module stored in memory and configured to control the charge regulating controller to provide a charge via the first port based on when the device is in at least one of an inactive state or a low activity state.

8. The device of claim 1, wherein at least one of the first connection or the second connection is a wireless connection.

9. An electronic device, comprising:

a controller;

a power source coupled to the controller;

a charging port configured to accept a connection configured to provide a charge to another device; and

a charge regulating controller coupled to the controller and configured to regulate providing a charge via the charging port based upon predetermined criteria, the predetermined criteria including at least one of an established threshold for the amount of charge of the power source above which the device will provide charge via the charging port, and an activity rate at which the device will provide charge via the charging port when the device is drawing power from the power source at a predetermined depletion rate.

10. The device of claim 9, wherein the predetermined criteria further comprise:

at least one user defined predetermined criterion established via a user interface to adjust at least one of magnitude, duration and availability of the charge the device will provide via the charging port.

11. The device of claim 9 wherein the charging port is a USB port.

12. The device of claim 9 further comprising:

a charge accepting port configured to accept a second connection configured to receive a charge, wherein the charge accepting port is a USB port.

13. The device of claim 9, further comprising:

a memory coupled to the controller; and

a device state module stored in memory and configured to control the charge regulating controller to provide a charge via the charging port based on when the device is in an inactive state.

14. A method of an electronic device including a controller, a power source coupled to the controller, and a charging port configured to accept a connection configured to provide a charge to another device, the method comprising:

regulating providing a charge via the charging port based upon at least one of an established threshold for the amount of charge of the power source above which the device will provide charge via the charging port, and an activity rate at which the device will provide charge via the charging port when the device is drawing power from the power source at a predetermined depletion rate.

15. The method of claim 14, further comprising:

regulating providing a charge via the charging port based upon at least one user defined predetermined criterion established via a user interface to adjust at least one of magnitude, duration and availability of the charge the device will provide charge via the charging port.

16. The method of claim 14, further comprising:

regulating the controller to provide a charge via the charging port based on when the device is in an inactive state.

17. The method of claim 14, wherein the electronic device further comprises an accepting port configured to accept a charge from another device, the method further comprising:

regulating accepting a charge from another device based upon predetermined charge accepting criteria.

18. The method of claim 17, further comprising:

establishing conditions via a user interface on accepting a charge, the conditions based on charge magnitude and charge duration.

19. The method of claim 14, further comprising:

configuring the charging port via a user interface to accept a connection configured to accept charge from another device.
