SYSTEMS AND METHODS FOR TRANSMITTING POWER TO RECEIVERS
First Claim
1. A computer-implemented method comprising:
- transmitting, by a transmitter, a low power wave to each of a plurality of segments in a transmission field; and
in response to the transmitter receiving a communications signal from a receiver containing data indicating a segment containing the receiver;
transmitting, by the transmitter, one or more power waves configured to converge at the segment containing the receiver.

Abstract
Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.

2. A computer-implemented method comprising:
-
transmitting, by a transmitter device, into a transmission field associated with the transmitter device one or more power waves and a communications signal, the communications signal containing a first set of transmission parameters defining one or more characteristics of the one or more power waves; in response to the transmitter receiving via the communications signal from a receiver device, device data indicating a location of the receiver in the transmission field; transmitting, by the transmitter device, a second set of transmission parameters into a sub-segment of the transmission field in accordance with the device data, the second set of transmission parameters defining the one or more characteristics of the one or more power waves; determining, by the transmitter device, one or more refined characteristics for the one or more power waves, based upon a set of one or more refined parameters defining the one or more refined characteristics, the refined parameters based upon refined location data received from the receiver device indicating a refined location within the sub-segment; generating, by the transmitter device, the one or more refined power waves having the one or more refined characteristics, according to the set of refined parameters; and transmitting, by the transmitter, the one or more refined power waves into the sub-segment of the transmission field, thereby forming a pocket of energy at the refined location. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A wireless power system comprising:
-
a mapping memory comprising non-transitory machine-readable storage media configured to store one or more receiver records containing data for one or more receivers; one or more transmitters associated with a transmission field, a transmitter comprising; an antenna array configured to transmit an exploratory power wave into one or more segments of a transmission field; a communications component configured to; transmit to each respective segment of the transmission field a set of parameters indicating one or more characteristics of the exploratory power wave transmitted into the respective segment, and transmit to a sub-segment of a first segment a second set of parameters indicating one or more refined characteristics of a second exploratory power wave transmitted into the sub-segment, upon receiving location data indicating the receiver is in the first segment from a receiver device at a location in a first segment; and a transmitter processor configured to determine the one or more characteristics for the exploratory wave based upon one or more parameters for each respective segment of the transmission field, and determine the one or more refined characteristics for the second exploratory power wave upon receiving the first segment location data from the receiver. - View Dependent Claims (14, 15, 16, 17, 18, 19)
