Receiver for wireless power reception having a backup battery
First Claim
1. A method for wireless power charging, the method comprising:
- when a receiver that is embedded within 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 provide a full or partial charge of 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 provide the full or partial charge of the backup battery, draining the backup battery to provide power to the battery of the electronic device.

Abstract
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.

10. 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 provide a full or partial charge of the backup battery, wherein the backup battery, after receiving the full or 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 (11, 12, 13, 14, 15, 16, 17, 18, 19)
