1. An inductive localization and charging system for detecting and charging a device, the system comprising:
a plurality of primary inductive coils arranged within a dielectric material; an input connector coupled to the plurality of primary inductive coils and configured to receive input power; a controller coupled to the plurality of primary inductive coils and to the input connector, the controller configured to:
selectively activate each primary coil of the plurality of primary inductive coils during a dwell time;measure a first voltage value for each activated primary coil of the plurality of primary inductive coils during the dwell time;determine whether the first voltage value is above a reference threshold voltage;set a flag indicating one or more activated primary coils is within operable proximity of a secondary coil in response to the determination that the first voltage value is above the reference threshold voltage;adjust the reference threshold voltage to decrease sensitivity in response to the flag indicating that two or more activated primary coils are within proximity of a secondary coil;determine that a first primary coil of the plurality of primary inductive coils is within operable proximity of an external secondary coil located in the device; andcontrol transfer of power between the first primary coil and the secondary coil to charge the device.
