WIRELESS POWERING OF ELECTRONIC DEVICES WITH SELECTIVE DELIVERY RANGE
First Claim
1. A method for wireless power transmission to an electronic device, comprising:
- connecting a pocket-forming transmitter to a power source;
generating RF waves from a RF circuit embedded within the transmitter;
controlling the generated RF waves with a digital signal processor in the transmitter;
transmitting the RF waves through antenna elements connected to the transmitter within a predefined range; and
capturing the RF waves forming pockets of energy converging in 3-D space at a receiver with antenna elements connected to the electronic device within the predefined range to convert the pockets of energy into a DC voltage for charging or powering the electronic device.

Abstract
The present disclosure 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 sender of energy and the receiver the device that is desired to charge or power. In the present disclosures, transmitters may power devices within a predefined range out of which devices may not be operable. This configuration may be beneficial in retail store settings where improved interactivity between users and devices is required. In addition, the configuration provides a safety feature to avoid unauthorized usage of electronic devices. A variation of this configuration is given in an academic setting where electronic devices utilized for learning are required to stay within school premises. Finally, an example of how such devices may improve their own form factors by using the disclosed wireless power transmission may be provided.
