RECEIVER FOR WIRELESS POWER RECEPTION HAVING A BACKUP BATTERY
First Claim
Patent Images
1. A method for wireless power charging, the method comprising:
- when a receiver coupled to an electronic device is within a threshold distance from a transmitter;
receiving, by the receiver, a plurality of wireless power transmission waves transmitted by the transmitter, wherein each wireless power transmission wave of the plurality of wireless power transmission waves constructively interferes with at least one other wireless power transmission wave of the plurality of wireless power transmission waves at the receiver;
converting, by the receiver, the plurality of wireless power transmission waves into usable electricity; and
providing, by the receiver, the usable electricity to a backup battery of the receiver to at least partially charge the backup battery, wherein the backup battery of the receiver is distinct and separate from a battery of the electronic device; and
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.

Abstract
The present disclosure provides a hybrid charging method for wireless power transmission based on pocket-forming. This method may extend the battery life of electronic devices such as tablets, smartphones, Bluetooth headsets, smart-watches among others. The method may include wireless power transmission through suitable techniques such as pocket-forming, while including an additional source of energy (backup battery) in the receiver attached or connected to the electronic device.

11. A receiver coupled to an electronic device, the receiver comprising:
-
a backup battery that is distinct and separate from a battery of the electronic device; and an antenna assembly configured to, when the receiver is within a threshold distance from a transmitter; receive a plurality of wireless power transmission waves transmitted by the transmitter, wherein each wireless power transmission wave of the plurality of wireless power transmission waves constructively interferes with at least one other wireless power transmission wave of the plurality of wireless power transmission waves at the receiver; convert the plurality of wireless power transmission waves into usable electricity; and provide the usable electricity to the backup battery to at least partially charge the backup battery, wherein the backup battery, after receiving at least a partial charge, is drained to provide power to the battery of the electronic device when the receiver is not within the threshold distance from the transmitter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
