METHODOLOGY FOR MULTIPLE POCKET-FORMING
First Claim
Patent Images
1. A method for multiple pocket-forming in wireless power transmission to a portable electronic device, comprising:
- sending short RF signals from a receiver through an antenna;
intercepting the short RF signals by an antenna in a transmitter having at least two antennas with a micro-controller for processing the RF signals;
decoding the RF signals to identify the gain and phase to determine the direction of the receiver;
transmitting pockets of energy consisting of RF waves from the transmitter through the at least two RE antennas to the receiver;
establishing channels or paths between the transmitter and the receiver for transmitting RF waves to converge in 3-D space with phase or relative amplitude adjustments to form constructive interference patterns for multiple pocket-forming to power the portable electronic device.

Abstract
The present disclosure describes a methodology for wireless power transmission based on multiple pocket-forming. This methodology may include one transmitter and two or more receivers, being the transmitter the source of energy and the receivers the devices that are 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 devices to which the receivers are connected. and thereafter aim pockets of energy to each device in order to power them.
