PORTABLE WIRELESS CHARGING PAD
First Claim
1. A method for wireless charging comprising:
- transmitting, by a transmitter embedded within a charging pad, at least two waves from antennas of the transmitter that converge to form a controlled constructive interference pattern near a surface of the charging pad when a receiver for an electronic device is positioned on the surface of the charging pad.

Abstract
The present disclosure provides a method and apparatus for improved wireless charging pads for charging and/or powering electronic devices. Such pads may not require a power cord for connecting to a main power supply, for example a wall outlet. In contrast, power may be delivered wireless to the foregoing pads through pocket-forming. A transmitter connected to a power source may deliver pockets of energy to the pads which through at least one embedded receiver may convert such pockets of energy to power. Lastly, the pads may power and/or charge electronic devices through suitable wireless power transmission techniques such as magnetic induction, electrodynamics induction or pocket-forming.
