First Claim
Patent Images
1. A method for transmitting wireless power, comprising:
- generating two or more RF power waves from a transmitter having at least two RF transmit antennas for transmitting two separate RF power waves;
forming controlled constructive interference patterns between the generated RF power waves to form pockets of energy;
converging the pockets of energy in 3-D space to a targeted electronic device; and
receiving the converged pockets of energy in a receiver having at least one antenna for charging or powering a targeted electronic device from the received pockets of energy.

Abstract
The present invention describes a methodology for wireless power transmission based on pocket-forming. This methodology may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. Both devices, the transmitter and receiver, may communicate to each other via a wireless protocol. By communicating to each other, the transmitter may identify and locate the device to which the receiver is connected and thereafter aim pockets of energy to the device in order to power it.

20. A method for wireless power transmission, comprising:
-
generating a communication RF signal from a receiver with identifier information of a chargeable electronic device connected thereto; broadcasting the identifier RF signal through an antenna of the receiver; intercepting the identifier RF signal by an antenna of a power transmitter with a controller; decoding the identifier RF signal by the controller to ascertain the gain and phase of the identifier RF signal sent by the power receiver including the direction or spatial location of the power receiver; establishing a power channel or path between the transmitter and receiver from the identifier RF signal information; transmitting controlled RF power waves from the transmitter to the receiver along the established channel or path; controlling the phase and amplitude of the RF power waves by the controller to form constructive and destructive interference patterns generating pockets of energy in a 3-dimensional shape from the constructive patterns and generating null-spaces from the destructive patterns to aim the pockets of energy to the receiver in order to charge or power the electronic device; converging the channels of 3-dimensional pockets of energy at the power receiver antenna for power input to the receiver; and converting the received pockets of energy into DC voltages for charging or powering the electronic device. - View Dependent Claims (21, 22)
