Abstract
Official abstract text for this publication.
Systems and methods for wireless power transmission based on object identification are provided. A radio frequency wireless power transmitter is in communication with a video camera for capturing image data (e.g., a visual pattern) of at least a portion of a transmission field of the radio frequency wireless power transmitter. A processor of the radio frequency wireless power transmitter is configured to identify an object when the visual pattern matches a pre-stored visual pattern representing the object, and control transmission of one or more radio frequency power transmission waves to a receiving electronic device based on a location of the identified object, wherein the receiving electronic device uses the one or more radio frequency power transmission waves to power or to charge the receiving electronic device.
First claim
Opening claim text (preview).
What is claimed is: 1 . A system for wireless power transmission, comprising: a radio frequency wireless power transmitter that is in communication with a video camera for capturing image data of at least a portion of a transmission field of the radio frequency wireless power transmitter, wherein the image data comprises a series of image frames; and one or more processors of the radio frequency wireless power transmitter configured to: detect motion of an object towards the transmission field by applying motion tracking analysis on the series of image frames; and send instructions to cause adjustments to transmission of one or more radio frequency power transmission waves by the radio frequency wireless power transmitter to a receiving electronic device based on the motion of the object, wherein the receiving electronic device uses the one or more radio frequency power transmission waves to power or to charge a power source used by the receiving electronic device.
