First Claim
Patent Images
1. A system for providing beamed power to a mobile receiving unit, comprising:
- a first power beaming unit configured to beam power to a receiving unit in a first power zone; and
a second power beaming unit configured to beam power to the receiving unit in a second power zone,wherein the first power beaming unit is configured to terminate power beaming as the receiving unit moves out of the first power zone and the second power beaming unit is configured to initiate power beaming as the receiving unit moves into the second power zone, wherein the first power beaming unit is configured to detect that the receiving unit has moved into the second power zone and to communicate to the second power beaming unit that the receiving unit has moved into the second power zone.

12. A method for providing beamed power to a mobile receiving unit, comprising:
-
beaming power from a first sending location to the receiving unit at a first receiving location; determining that the receiving unit is moving from the first receiving location to a second receiving location; and beaming power from a second sending location to the receiving unit at the second receiving location, wherein determining includes detecting from the first sending location that the receiving unit is moving away from the first receiving location and communicating to the second sending location that the receiving unit is moving toward the second receiving location. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A power source configured to beam power to a receiving unit, comprising:
-
a location unit configured to locate a receiving unit in need of power by initiating contact with the receiving unit by broadcasting a signal indicative of its ability to supply power; and receiving a request for power from the receiving unit in response to the broadcast signal; a first power beaming unit configured to beam power to charge the receiving unit; and a decision unit configured to determine that the receiving unit should be powered by a second power beaming unit and to direct the first power beaming unit to discontinue beaming power to the receiving unit upon transfer of responsibility for power beaming to the second power beaming unit. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
