Abstract
A RF wireless charging enclosure configured to enable efficient wireless charging of a CE device in the enclosure while also allowing wireless communication of the CE device to devices outside the enclosure. In one example, time multiplexing is used such that the CE device is enabled to either be charged, or to communicate with a device outside the enclosure. In another example, frequency division is used such that the CE device is charged at a first frequency, and simultaneously communicates through the enclosure at a second different frequency.
Claims20
An RF device charger, comprising:
- an enclosure having at least one wall encompassing a cavity, wherein the cavity is configured to prevent communication of RF signals through the at least one wall;
- a RF transmitter configured to generate an RF charge signal within the cavity at a first frequency, the RF charge signal configured to wirelessly charge a device within the cavity;
- and
- a switch coupled to the enclosure wall and configured to pass an RF communication signal through the at least one wall at a second frequency that is different from the RF charge signal first frequency, and reject communication of the RF charge signal through the at least one wall to prevent the RF charge signal from emanating from the enclosure.
A method of RF charging a device in an RF device charger, comprising:
- an enclosure having at least one wall encompassing a cavity, wherein the cavity is configured to prevent communication of RF signals through the at least one wall;
- a RF transmitter configured to generate an RF charge signal within the cavity at a first frequency, the RF charge signal configured to wirelessly charge a device within the cavity;
- and
- a switch coupled to the enclosure wall and configured to pass an RF communication signal through the at least one wall at a second frequency that is different from the RF charge signal first frequency, and reject communication of the RF charge signal through the at least one wall to prevent the RF charge signal from emanating from the enclosure;
- comprising the steps of:
- placing the device in the enclosure;
- and
- RF charging the device in the enclosure, wherein switch passes an RF communication signal through the at least one wall at a second frequency that is different from the RF charge signal first frequency, and rejects communication of the RF charge signal through the at least one wall to prevent the RF charge signal from emanating from the enclosure.
