First Claim
Patent Images
1. A power system receiver, comprising:
- a plurality of antenna elements;
a rectifier, operatively coupled to the plurality of antenna elements;
a power converter, operatively coupled to the rectifier, wherein the power converter and rectifier are configured to receive pocket-forming energy in three dimensional space for use in charging a battery; and
a processing apparatus, configured to perform a self-test of the power system receiver upon the occurrence of a predetermined event.

Abstract
Disclosed here are wireless power delivery systems including one or more wireless power transmitters and one or more power receivers. Disclosed here are methods of using self-test software for fault detection in wireless power receivers. The methods include the analysis of one or more system operational metrics to evaluate the status of wireless power receivers. The results of the tests may be sent to wireless power transmitters to further analysis; all test results ultimately are sent to the operator of the wireless power delivery system.
