Abstract

An apparatus and method for communication with a wireless power transmitter are disclosed. According to one aspect, a device may include an antenna for wirelessly transmitting a power signal at a power carrier and data signal at a data signal carrier. A receiver may be configured to receive the power signal and the data signal and determine a reference signal based on the received signal.

Description

technical field [0001] The present invention is directed to methods and systems for communication between a wireless power transmitter and a wireless power receiver. Background technique [0002] An increasing number and variety of electronic devices are powered via rechargeable batteries. Such devices include mobile phones, portable music players, laptop computers, tablet computers, computer peripherals, communication devices (eg, Bluetooth devices), digital cameras, hearing aids, and the like. While battery technology has improved, battery-powered electronic devices increasingly require and consume greater amounts of power, requiring frequent recharging. Rechargeable devices are often charged via a wired connection through a cable or other similar connector that physically connects to a power source. Cables and similar connectors can sometimes be inconvenient or bulky, among other disadvantages. A wireless charging system capable of transferring power in free space that...
