RETROFITTING WIRELESS POWER AND NEAR-FIELD COMMUNICATION IN ELECTRONIC DEVICES
First Claim
1. Power circuitry for an electronic device, comprising:
- an antenna for receiving a signal from a coupling-mode region of near-field radiation generated by a transmit antenna; and
conversion circuitry for converting the signal to DC power to be used by an electronic device;
wherein the antenna and the conversion circuitry are configured to electrically and mechanically couple to the electronic device using an existing connection and existing form factor of a battery compartment of the electronic device.

Abstract
Exemplary embodiments are directed to retrofitting existing electronic devices for wireless power transfer and near-field communication. Retrofitting circuitry includes an antenna for receiving a signal from an external source, and conversion circuitry for converting the signal to be used by an electronic device. The antenna and conversion circuitry are configured to retrofit to the electronic device, where the electronic device did not originally include the antenna or conversion circuitry. The antenna and conversion circuitry may be configured to receive and convert the signal to generate wireless power for the electronic device. The antenna and the conversion circuitry may also be configured to enable the electronic device to send and receive near-field communication data.
