WIRELESS SOUND 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 SW waves from a SW circuit embedded within the transmitter;
controlling the generated SW waves with a digital signal processor in the transmitter;
transmitting the SW waves through transducer elements connected to the transmitter within a predefined range; and
capturing the SW waves forming pockets of energy converging in 3-D space at a receiver with sensor 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 sound 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 connected to an electronic device that is desired to charge or power. The transmitters power devices within a predefined range. 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.
