Abstract

A universal charger which can charge multiple electronic devices, such as a keyboard, mouse, remote control, etc. In one embodiment, a user is directed to a website over the internet to a site containing charging profiles for multiple devices. The user selects the particular devices the user will want to charge and downloads the charging profiles. The charging profiles are provided to the universal charger device. A number of mechanisms are provided to identify the device, such as wireless or wired communication with the device or reading an RFID tag in the device. Various embodiments are disclosed, including having smaller devices (remote control, mouse) moved to the charger and the charger move to larger devices (keyboard). Also, various indicators are shown to indicate which device needs charging, and various lighting schemes show the amount of charging.

Claims

1. A method for configuring a charger for a plurality of devices, comprising:

accessing over a network a database of charging profiles;

selecting at least one charging profile corresponding to a device to be charged; and

downloading said charging profile to said charger.

2. The method of claim 1 wherein said charging profiles are downloaded from said database to a computer, and from said computer over a USB connection to said charger.

3. The method of claim 1 wherein said accessing occurs automatically upon detection of said device by a computer.

4. The method of claim 1 further comprising identifying said device by said charger communicating with said device.

5. The method of claim 4 wherein said communication is over a USB connection.

6. The method of claim 4 wherein said communication is wireless.

7. The method of claim 6 wherein said wireless communication comprising reading an RFID tag in said device.

8. The method of claim 1 wherein said charger operates as a stand alone device once the profiles of desired associated devices have been downloaded.

9. The method of claim 1 further comprising displaying devices for the user to select to charge and an indication of the charging status.

11. The charger of claim 8 further comprising:

a memory in said charger for storing charging profiles for said plurality of devices.

10. A charger comprising:

a communication port for communicating with a computer and at least one of a plurality of devices;

a charging interface for providing charge to said plurality of devices.

12. The charger of claim 10 wherein said charging interface further comprises:

a USB connector for providing power to said plurality of devices.

13. The charger of claim 10 further comprising:

a USB hub; and

a plurality of USB connectors.

14. The charger of claim 10 wherein said charging interface comprises:

a ribbon cable; and

a spring mechanism for extending and retracting said ribbon cable into said charger.

15. The charger of claim 10 wherein said charging interface comprises:

a first low profile connector, said charger being movable to connect said low profile connector to a stationary first device; and

a second connector above said first connector, said second connector supporting and connecting to a second device.

16. The charger of claim 10 wherein said charging interface comprises:

a removable power cell.

17. The charger of claim 10 wherein said communication port comprises:

a first USB port for connecting to said computer; and

a second USB port for connecting to one of said plurality of devices.

18. The charger of claim 10 further comprising:

a light display for providing a light indicator that moves over time toward one of said devices; and

a charge monitoring module configured to send a signal to said device to activate a light indicator on said device when the light indicator on said charger reaches a point proximate said device.

19. The charger of claim 10 further comprising:

a plurality of different visual indicators, each of said visual indictors corresponding to a similar visual indicator on one of said devices.

20. The charger of claim 19 wherein each of said different visual indicators is a different color.

21. The charger of claim 10 further comprising:

a connector compatible with all types of AC plugs worldwide.

22. A charging system comprising:

(a) a charger including

a charge light indicator; and

(b) a device including

a connector for connecting to said charger so that said charge light indicator is immediately adjacent said device;

a charge light indicator positioned on said device adjacent said connector so that light can appear to move from said charge light indicator on said charger to said charge light indicator on said device.
