SYSTEMS AND METHODS OF OBJECT DETECTION IN WIRELESS POWER CHARGING SYSTEMS
First Claim
1. A method for wireless power transmission comprising:
- transmitting, by a transmitter, power waves that converge to form constructive interference at a location associated with a receiver;
generating, by at least one thermal imaging camera in communication with the transmitter, a thermal image of at least a portion of a transmission field of the transmitter;
identifying, by the transmitter, a living being in the transmission field of the transmitter based upon temperature data in the thermal image;
determining, by the transmitter, a proximity of the identified living being to the power waves; and
adjusting, by the transmitter, a power level of the power waves upon determining that the proximity of the living being is within a predefined distance from the power waves.

Abstract
Embodiments disclosed herein discloses a wireless charging system configured to generate and transmit power waves that, due to physical waveform characteristics converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pocket of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pocket of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy. Video sensors capture actual video images of fields of view within the transmission field, and a processor identifies selected objects, selected events, and/or selected locations within the captured video images.

11. A transmitter for wireless power transmission comprising:
-
a thermal imaging camera configured to generate a thermal image of at least a portion of a transmission field of the transmitter; a controller configured to receive a thermal image from the thermal imaging cameras, identify a living being in the transmission field of the transmitter based upon temperature data in the thermal image, determine a proximity of the identified living being to power waves generated by the transmitter, and adjust a power level of the power waves upon determining that the proximity of the living being is within a predefined distance from the power waves. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
