Patent attributes
The present disclosure provides devices and methods for wireless power transmission. These devices and methods may extend the battery life of electronic devices such as tablets, smartphones, Bluetooth headsets, smart-watches among others. An example method may include, when a receiver coupled to an electronic device is within a threshold distance from a transmitter: (i) receiving a plurality of wireless power transmission waves transmitted by the transmitter, (ii) converting the plurality of wireless power transmission waves into usable electricity, and (iii) providing the usable electricity to a backup battery of the receiver to at least partially charge the backup battery. Further, when the receiver is not within the threshold distance from the transmitter, and after providing the usable electricity to the backup battery to at least partially charge the backup battery, draining the backup battery to provide power to the battery of the electronic device.
