A system and method for detecting, characterizing, and tracking an inductive power receiver proximate to an inductive charging surface of an inductive charger. One or more resonators and one or more sensors provide information that can be utilized to detect, characterize, and track the inductive power receiver. The resonators can be configured to determine position of a remote device using magnitude or phase of sensors associated with resonators. In addition, by monitoring the inductive power transmitter and the resonators, the charger can differentiate between whether parasitic metal is present, a remote device is present, or both are present. |
