Abstract

A system includes a network and a controller. The network has a plurality of nodes. The plurality of nodes includes a first node and a second node. The first node is configured to transmit energy to the second node. The first node is magnetically coupled with the second node. The plurality of nodes includes at least one controllable node having a performance parameter and including at least one sensor. The at least one sensor is configured to generate a signal corresponding to energy received by the sensor. The controller has an output coupled to the at least one controllable node. The output is determined based on the signal. The performance parameter is selected based on the output.
