Wireless power transmission with selective range
First Claim
1. A method for wireless power transmission with selective range to power a portable electronic device, comprising:
- generating pocket-forming RF waves from a transmitter through an antenna connected to the transmitter;
accumulating pockets of energy in regions of space in the form of constructive interference patterns of the generated RF waves;
employing a selective range for charging or powering the electronic device in a predetermined variety of spots with the accumulated pockets of energy surrounded by null-spaces without accumulated pockets of energy; and
implementing an adaptive power focusing to avoid obstacles interfering with the RF signals between the receiver and the transmitter for regulating two or more receivers providing charging or powering of the portable 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 source of energy and the receiver the device that is desired to charge or power. The transmitter may identify and locate the device to which the receiver is connected and thereafter aim pockets of energy to the device in order to power it. Pockets of energy may be generated through constructive and destructive interferences, which may create null-spaces and spots of pockets of energy ranged into one or more radii from transmitter. Such feature may enable wireless power transmission through a selective range, which may limit operation area of electronic devices and/or may avoid formation of pockets of energy near and/or over certain areas, objects and people.
