1. A method of wireless power transmission, the method comprising:
- generating, by a receiver, location data associated with one or more objects based upon one or more object detection signals reflected from the one or more objects and indicating a location of each respective object in relation to the receiver;
transmitting, by the receiver, one or more communications signals containing the location data to the transmitter; and
receiving, by the receiver, from one or more antennas of the transmitter one or more power waves having one or more waveform characteristics, wherein the characteristics are based on the location data generated for each respective object.

Abstract
Embodiments disclosed herein may include a receiver configured to determine location data associated with one or more objects. The receiver transmits the location data associated with the one or more objects to a transmitter configured to transmit wireless power waves. The receiver then receives the wireless power waves transmitted by antennas of the transmitter having one or more characteristics where the one or more characteristics are defined based on the location data by a processor of the transmitter.

8. A method of wireless power transmission, the method comprising:
-
emitting, by a first antenna of a receiver, a plurality of outbound object detection signals, each respective object detection signal having a successively stepped frequency with respect to a preceding object detection signal; receiving, by a second antenna of the receiver, one or more inbound object detection signals that are reflected from one or more objects, wherein at least one inbound object detection signal is reflected from an object, and wherein the at least one inbound object detection signal indicates a location of the object in relation to the receiver; generating, by a processor of the receiver, location data associated with each respective object based on the one or more inbound object detection signals; transmitting, by a communications component of the receiver, to a transmitter one or more communication signals containing the location data associated with each of the one or more objects; and receiving, by a third antenna of the receiver, from the transmitter one or more power waves having one or more characteristics, wherein the characteristics are based on the location data associated with the one or more objects. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A receiver in a wireless power transmission system comprising:
-
a first antenna configured to emit a plurality of outbound detection signals, each outbound detection signal having a successively stepped frequency; a second antenna configured to receive a plurality of inbound detection signals reflected from one or more objects, wherein one or more detection signals are reflected from an object; a processor configured to generate location data associated with each respective object based on the one or more inbound detection signals received from the respective object, wherein the location data of each respective object indicates the location of the respective object in relation to the receiver; a communications component configured to transmit to the transmitter communications signals containing the location data associated with the one or more objects; and a third antenna configured to receive from the transmitter one or more power waves having one or more characteristics causing the one or more power waves to converge at a location proximate to the receiver based on the location data associated with the one or more objects. - View Dependent Claims (16, 17, 18, 19, 20)
