Abstract

A battery charging station is equipped with radio frequency power transmitters, induction power transmitters, and ultrasound power transmitters so as to concurrently charge electronic devices. The battery charging station is operable to network the electronic devices through wireless communication. In this regard, the battery charging station may coordinate or arrange the radio frequency power transmitters, the induction power transmitters and/or the ultrasound power transmitters so that the resulting power transmission from the battery charging station to one or more intended networked electronic devices may be maximized. The battery charging station may wirelessly communicate with the electronic devices for device networking. The networked electronic devices may be connected to a computer network for various network services such as, for example, network advertising and software downloading or uploading. Both direct and in-direct device-to-device communication may be supported among the networked electronic devices. The battery charging station maintains data communication during battery charging.

Claims

1. A method of radio frequency (RF) power transmission to selectively charge an electronic device, said method comprising:

identifying said electronic device;

configuring one or more antennas to provide RF power from an RF power transmitter;

providing said RF power to a geographic area of interest for RF power transmission to said identified electronic device when a user preference allows for receiving wireless power within said geographic area of interest.

2. The method of claim 1 wherein said identified electronic device in said geographic area of interest is charged when device identification information is registered.

3. The method of claim 2 wherein said user preference allows for receiving power to wirelessly charge said identified electronic device.

4. The method of claim 2 wherein said device identification information includes at least one of media access control address (MAC ID), network IP address, name, serial number, product name, product manufacturer, and product capabilities.

5. The method of claim 1 wherein said RF power is focused on a sensed location of a battery adapter of said identified electronic device in said geographic area of interest.

6. A method of radio frequency (RF) power transmission to selectively charge an electronic device, said method comprising:

identifying said electronic device;

configuring one or more antennas to form an RF beam using RF signals from a power transmitter;

focusing said RF beam to a sensed location in a geographic area of interest of said identified electronic device for power transmission to said identified electronic device, and to avoid transmitting power to non-sensed locations not in said geographic area of interest;

wherein a user preference allows for receiving power to wirelessly charge said identified electronic device.

7. The method of claim 6 wherein said RF beam is focused on a battery adapter that provides power to said identified electronic device.

8. The method of claim 6 wherein said RF beam is focused on a battery adapter that and provides power only to said identified electronic device.

9. The method of claim 6 wherein said RF beam is focused on an RF power receiver of said identified electronic device.

10. The method of claim 6 wherein said identified electronic device is not charged when device identification information is not registered.

11. The method of claim 10 wherein said device identification information includes at least one of media access control address (MAC ID), network IP address, name, serial number, product name, product manufacturer, and product capabilities.

12. The method of claim 6 wherein a user preference allows for receiving wireless power within said geographic area of interest.

13. The method of claim 6 further comprising steering said RF beam to focus said RF beam on said identified electronic device in response to a change in location of said identified electronic device.

14. A method of radio frequency (RF) power transmission to selectively charge an electronic device, said method comprising:

identifying said electronic device;

configuring one or more antennas to form an RF beam using RF signals from a power transmitter;

focusing said RF beam to a sensed location in a geographic area of interest of said identified electronic device for power transmission to said identified electronic device;

wherein a user preference allows for receiving wireless power within said geographic area of interest.

15. The method of claim 14 wherein said RF beam is focused on a battery adapter that provides power to said identified electronic device.

16. The method of claim 14 wherein said RF beam is focused on an RF power receiver of said identified electronic device.

17. The method of claim 14 wherein said identified electronic device is not charged when device identification information is not registered.

18. The method of claim 14 wherein a user preference allows for receiving power to wirelessly charge said identified electronic device.

19. A method of radio frequency (RF) power transmission to selectively charge an electronic device, said method comprising:

identifying said electronic device;

configuring one or more antennas to form an RF beam using RF signals from a power transmitter; and

focusing said RF beam to a sensed location in a geographic area of interest of said identified electronic device for power transmission to said identified electronic device when a user preference allows said identified electronic device to be charged using said power.

20. The method of claim 19 wherein said RF beam is focused on a battery adapter that provides power to said identified electronic device.

21. The method of claim 19 wherein said RF beam is focused on a battery adapter that and provides power only to said identified electronic device.

22. The method of claim 19 wherein said RF beam is focused on an RF power receiver of said identified electronic device.

23. The method of claim 19 wherein said identified electronic device is not charged when device identification information is not registered.

24. The method of claim 23 wherein said device identification information includes at least one of media access control address (MAC ID), network IP address, name, serial number, product name, product manufacturer, and product capabilities.

25. The method of claim 19 wherein the user preference allows said identified electronic device to be charged within said geographic area of interest.

26. The method of claim 19 further comprising steering said RF beam to focus said RF beam on said identified electronic device in response to a change in location of said identified electronic device.

27. The method of claim 19 wherein said user preference allows for power transmission to said identified electronic device.

28. The method of claim 19 further comprises avoiding power transmission to locations outside of said geographic area of interest.
