Abstract
A charging system may include a charging apparatus having a controller and a power transmitter. The controller may be configured to determine a device position relative to the controller based on at least one signal received from the device. The controller may also be configured to determine whether the device position is at an optimal position, and provide feedback indicative of the device position.
