Patent Images
1. A system, comprising:
- a controller;
a first node remote from the controller, the first node configured to transmit power wirelessly to a receiver that converts the power transmitted wirelessly from the first node into a current, the first node defining a first coverage area when wirelessly transmitting power, the first node configured to receive a first instruction effecting an operation of the first node from the controller; and
a second node remote from the controller, the second node configured to transmit power wirelessly to a receiver that converts the power transmitted wirelessly from the second node into a current, the second node defining a second coverage area when wirelessly transmitting power, the second node configured to receive a second instruction effecting an operation of the second node from the controller.

Abstract
A network for power transmission to a receiver that converts the power into current includes a first node for transmitting power wirelessly in a first area. The first area has a minimum electric or magnetic field strength. The network includes a second node for transmitting power wirelessly in a second area. The second area has a minimum electric or magnetic field strength and overlaps the first area to define an overlap area. In another embodiment, the network includes a source in communication with the first and second nodes which provides power to them. Also disclosed are methods for power transmission to a receiver that converts the power into current.

11. An apparatus, comprising:
-
a transmitter having a first antenna and a second antenna, the first antenna of the transmitter configured to transmit power wirelessly to a receiver that converts the power transmitted wirelessly from the first antenna into a current, the first antenna defining a first coverage area when wirelessly transmitting power, the second antenna of the transmitter configured to transmit power wirelessly to a receiver that converts the power transmitted wirelessly from the second antenna into a current, the second antenna defining a second coverage area that overlaps at least a portion of the first coverage area when wirelessly transmitting power, the transmitter configured to alternate operation of the first antenna and the second antenna, the transmitter configured to wirelessly receive instructions from a controller separate from the transmitter, the transmitter configured to control operation of the first antenna and the second antenna based on the instructions from the controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
