WIRELESS POWER TRANSMISSION WITH SELECTIVE RANGE
First Claim
1. A method for wireless power transmission comprising:
- generating, by a transmitter, radio frequency (RF) waves through an antenna connected to the transmitter;
defining, by the transmitter, a region of space to form a pocket of energy for charging or powering an electronic device, wherein defining the region of space comprises selecting a range of distance from the transmitter for the pocket of energy;
directing, by the transmitter, the RF waves to accumulate in the region of space in a form of constructive interference patterns; and
generating, by the transmitter, a null-space in a form of destructive interference patterns of the generated RF waves outside of the selected range from the transmitter.

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.

4. A system for wireless power transmission comprising:
-
a transmitter configured for generating radio frequency (RF) waves through an antenna connected to the transmitter; a micro-controller within the transmitter configured to control the RF waves to direct the RF waves to accumulate as a pocket of energy in a region of space in a form of constructive interference patterns of the generated RF waves, thereby selecting a range from the transmitter configured for charging or powering an electronic device in the region of space having the pocket of energy, and the micro-controller further configured to generate a null-space in the form of destructive interference patterns of the generated RF waves outside of the selected range. - View Dependent Claims (5, 6, 7, 8, 9)

10. A system for wireless power transmission comprising:
-
a transmitter configured for generating at least two radio frequency (RF) waves and short RF control signals, the transmitter comprising; at least two RF antennas configured to transmit at least two RF waves through the antennas converging in 3-d space to accumulate as a pocket of energy in the form of constructive interference patterns of RF waves; a micro-controller configured for controlling constructive interference patterns of the RF waves to accumulate the pocket of energy in a predetermined areas or region in 3-D space and for controlling the destructive interference patterns of the RF waves to form a null-space; and wherein the constructive interference patterns of RF waves form the pocket of energy within a range from the transmitter for charging or powering the electronic device and wherein the destructive interference patterns of RF waves form the null-space outside of the range. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
