SUBSCRIPTION BASED MISO AND MIMO WIRELESS ENERGY TRANSFER
First Claim
1. A subscription based MIMO radio-frequency energy transfer system, comprising:
- one or more storage media having instructions stored thereon at least directing the system to;
determine a presence of one or more devices in an area, wherein the one or more devices derive at least part of their operating energy from incident radio-frequency energy;
verify that the one or more devices are subscribed devices; and
transfer radio-frequency energy to the one or more subscribed devices according to a power level representing radio-frequency energy incident upon the subscribed devices;
a plurality of transmitters; and
a transmitter controller for controlling the plurality of transmitters, the transmitter controller configured to adjust an amplitude and phase of each transmitter of the plurality of transmitters for transferring the energy to the subscribed devices.

Abstract
Subscription based multiple-in-put-single-output and multiple-input-multiple-output wireless energy transfer enables selective charging and powering of mobile devices using a plurality of spatially distributed transmitters that are synchronized under the control of a transmitter controller. Amplitude, phase, and frequency of each transmitter is controlled to promote or deny the transfer of energy to particular mobile devices or positions through optimization techniques based on the incident power level at each mobile device subscribing to the system. Measurements related to the incident power level may be directly provided by the mobile device or the incident power is remotely determined through analysis of backscatter gains.
