Proximity transmitters for wireless power charging systems
First Claim
1. A wireless charging proximity transmitter comprising:
- an array of one or more antennas; and
a surface layer proximate to the array of antennas,wherein the transmitter is configured to transmit one or more power waves to a receiver in response to a device associated with the receiver being within a proximity threshold of the surface layer of the proximity transmitter.

Abstract
Disclosed herein are systems and methods addressing the shortcomings in the art, and may also provide additional or alternative advantages as well. The embodiments described herein provide a wireless charging proximity transmitter configured to intelligently generate waveforms of various types, such as radio-frequency waves and ultrasound waves, among others. The wireless charging transmitter may be used for providing energy to a receiver that is proximately located to the transmitter. The receiver may be coupled to, or may be a component of, an electrical device that is intended to receive the power from the wave-based energy produced by the wireless proximity transmitter.
