Abstract

In an embodiment, a wireless power distribution system is disclosed. The wireless power distribution system includes a routing module having at least one processor configured to determine a route for a power-receiving device to travel responsive to receiving input about one or more characteristics associated with the power-receiving device or one or more wireless power transmitters for delivering power to the power-receiving device. The wireless power distribution system further includes the one or more wireless power transmitters operably coupled to the routing module. The one or more wireless power transmitters are configured to wirelessly transmit the power to the device at one or more locations along the route.

Claims

a routing module configured to determine a route on which the power-receiving device can travel to receive wireless power from a wireless power distribution system while the power-receiving device is moving along the route, the routing module also being configured to output one or more routing signals encoding the route;

a transmitter configured to send one or more signals encoding information about one or more characteristics of the power-receiving device to the routing module;

a wireless receiver configured to receive wireless power from the wireless power distribution system while the power-receiving device is moving along the route; and

a power converter coupled to the wireless receiver and configured to convert the wireless power to electrical energy.

2. The power-receiving device of claim 1, further comprising a display coupled to the wireless receiver and configured to display information about the route.

3. The power-receiving device of claim 1, wherein the transmitter and the wireless receiver form a wireless transceiver.

4. The device of claim 1, wherein the one or more characteristics associated with the power-receiving device include at least one of type of power receiver of the power-receiving device, amount of power requested by the power-receiving device, maximum power reception capability of the power-receiving device, cumulative energy requested by the power-receiving device, location of the power-receiving device, speed at which the power-receiving device is traveling, operating mode of the power-receiving device, or energy storage capacity of the power-receiving device.

15. The power-receiving device of claim 1, wherein the routing module is configured to output routing signals indicating an altered route based at least partially on the one or more characteristics.

16. The power-receiving device of claim 1, wherein the wireless receiver is configured to receive wireless power from a plurality of wireless power transmitters of the wireless power delivery system while the power-receiving device is moving along the route.

17. The power-receiving device of claim 1, wherein the wireless receiver and power converter are integrated in a vehicle.

18. The power-receiving device of claim 1, wherein the wireless receiver and power converter are integrated in a portable electronic device.

19. The power-receiving device of claim 18, wherein portable electronic device includes one or more of a cell phone, a laptop computer, or a personal data assistant.

20. The power-receiving device of claim 1, wherein the power converter includes at least one of an optical-electrical converter, an antenna, a magnetic-electrical converter, or a radio-frequency-electrical converter.

21. The power-receiving device of claim 1, wherein the power converter is configured to convert at least a portion of the wireless power transmitted into electricity and provide some of the electricity to power the power-receiving device.

5. A wireless power distribution system, comprising:

a power-receiving device configured to wirelessly receive power as the power-receiving device is moving along a route, the route including one or more paths along which the power-receiving device can travel to receive wireless power while the power-receiving device is moving; and
