Abstract

Some embodiments provide a system for charging devices. The system includes a master device and a slave device. Some embodiments provide a method for charging devices in a system that includes a slave device and a master device. The slave device includes (1) an antenna to receive a radio frequency (RF) beam and (2) a power generation module connected to the antenna that converts RF energy received by the slave antenna to power. The master device includes (1) a directional antenna to direct RF power to the antenna of the slave device and (2) a module that provides power to the directional antenna of the master device.

Claims

1-46. -46 (canceled)

47. :

A method of wirelessly charging an electronic device in a car including a wireless radio frequency (RF) transmitting device receiving power from a power source in the car, the method comprising;
