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 chord 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.

15. A method for a portable wireless charging pad, comprising:
-
supplying pockets of energy to a pad receiver including circuitry of an antenna element, a digital signal processor (DSP), a rectifier, a power converter and a communications device connected to a pad battery; pocket-forming in a pad transmitter including circuitry of antenna elements, a RF integrated chip controlled by a DSP for pocket-forming to develop pockets of energy for charging and powering a battery in an electronic device in proximity to the pad and a communication device controlled by the DSP; pocket-forming in a power transmitter supplying pockets of energy to the pad receiver; and communicating the power level of the pad battery from the pad receiver to the power transmitter through short RF signals between the pad receiver and power transmitter communication devices, respectively, over conventional wireless communication protocols. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A method for a portable wireless charging pad, comprising:
-
searching for a wireless charging request from a portable electronic device within a predetermined range from the charging pad; scanning for a standard communication protocol signal representing the charging request from the portable electronic device; pocket-forming from a pad transmitter for supplying pockets of energy to an electronic device receiver requiring the charging; and ending wireless power transmission to the electronic device when a predetermined charging has occurred or when the electronic device is out of range from the charging pad. - View Dependent Claims (24)

25. A portable wireless charging pad, comprising:
-
a pad receiver embedded within the charging pad connected to antenna elements on a surface of the pad for receiving pockets of energy from a pocket-forming power transmitter to charge a pad battery; and a pad pocket-forming transmitter powered by the pad battery including a RF chip connected to antenna elements for generating pockets of energy to charge or power a portable electronic device having a receiver to capture the pockets of energy from the pad transmitter when in the proximity of the charging pad. - View Dependent Claims (26, 27, 28, 29, 30)
