Abstract
A method for wireless power delivery, preferably including: determining transmitter-receiver proximity, assessing transmission parameters, and/or transmitting power based on a transmission plan. A system for wireless power delivery, preferably including a plurality of receivers and one or more transmitters.
Claims19
A method for wireless power transmission, comprising:
- determining a first transmission direction for wireless power transmission from a transmitter to a first receiver, wherein the first receiver is associated with a first power reception metric;
- determining a second transmission direction, different from the first transmission direction, for wireless power transmission from the transmitter to a second receiver separate from the first receiver, wherein the second receiver is associated with a second power reception metric;
- based on the first and second transmission directions, calculating a multi-beam configuration for the transmitter, the multi-beam configuration associated with a multi-beam transmission pattern comprising:
- a first beam substantially along the first transmission direction;
- and
- a second beam substantially along the second transmission direction;
- based on the multi-beam configuration, determining an optimized configuration for the transmitter, wherein determining the optimized configuration comprises evaluating the first and second power reception metrics based on the optimized configuration;
- and
- at the transmitter, wirelessly transmitting power to the first and second receivers based substantially on the optimized configuration.

A method for wireless power transmission from a transmitter to a plurality of receivers, the method comprising:
- determining a plurality of transmission directions, wherein each transmission direction of the plurality of transmission directions is associated with wireless power transmission from the transmitter to a different receiver of the plurality of receivers;
- selecting a subset of the plurality of receivers, wherein each receiver of the subset is associated with:
- a respective transmission direction of a subset of the plurality of transmission directions;
- and
- a respective power reception metric of a plurality of metrics;
- based on the subset of transmission directions, calculating a multi-beam configuration for the transmitter, the multi-beam configuration associated with a multi-beam transmission pattern, wherein the multi-beam transmission pattern comprises a plurality of beams, each beam of the plurality directed substantially along a different transmission direction of the subset;
- based on an objective function and the multi-beam configuration, performing an optimum search to determine an optimized configuration for the transmitter, wherein performing the optimum search comprises, for each of a plurality of transmitter configurations, evaluating the objective function for the transmitter configuration, wherein the objective function is determined based on the plurality of metrics;
- and
- at the transmitter, wirelessly transmitting power to the subset of receivers based substantially on the optimized configuration.
