Abstract
In an embodiment, a method for heating a personal device using a wirelessly-powered heating device includes: wirelessly receiving power with a receiving coil of the wirelessly-powered heating device, the receiving coil located inside the personal device, where the receiving coil is coupled to a capacitor of the wirelessly-powered heating device to form a receiver resonant tank; and heating the personal device with heat produced by a resistance of the receiving coil, where the receiving coil functions as a receiver antenna and as a heat producing element.
Claims28
A method for heating a personal device, the method comprising:
- wirelessly receiving, by a receiving coil of a wirelessly-powered heating device, power, the receiving coil being located inside the personal device, wherein the receiving coil is coupled to a capacitor of the wirelessly-powered heating device to form a receiver resonant tank;
- heating the personal device with heat produced by a resistance of the receiving coil, wherein the receiving coil functions as a receiver antenna and as a heat producing element;
- and
- wirelessly communicating, by the wirelessly-powered heating device, with another device, wherein the other device is a device different than a device comprising a resonant wireless power transmitter.
A method for heating a personal device, the method comprising:
- wirelessly receiving power with a receiving coil of a wirelessly-powered heating device, the receiving coil located inside the personal device, wherein the receiving coil is coupled to a capacitor of the wirelessly-powered heating device to form a receiver resonant tank;
- and
- heating the personal device with heat produced by a resistance of the receiving coil, wherein the receiving coil functions as a receiver antenna and as a heat producing element,
- wherein the wirelessly-powered heating device comprises a bridge rectifier having a first terminal connected to the first terminal of the receiving coil and a second terminal connected to the second terminal of the receiving coil, and a controller coupled to the bridge rectifier.
A method for heating a personal device, the method comprising:
- wirelessly receiving power with a receiving coil of a wirelessly-powered heating device, the receiving coil located inside the personal device, wherein the receiving coil is coupled to a capacitor of the wirelessly-powered heating device to form a receiver resonant tank;
- heating the personal device with heat produced by a resistance of the receiving coil, wherein the receiving coil functions as a receiver antenna and as a heat producing element;
- and
- communicating, from the wirelessly-powered heating device to another device, using Bluetooth or WiFi.
