摘要： An apparatus for detecting a presence of an object is provided. The apparatus includes an inductive sensing coil that is configurable to generate a first magnetic field. The inductive sensing coil is configured to have an electrical characteristic that is detectable when generating the first magnetic field. The electrical characteristic is configured to vary as a function of a second time-varying magnetic field simultaneously applied to the object. The apparatus comprises a controller configured to detect a change in the electrical characteristic and determine a presence of the object based on the detected change in the electrical characteristic. The electrical characteristic comprises one or more of an equivalent resistance, an equivalent inductance, an equivalent impedance, and an impulse response of the inductive sensing coil. The object comprises one or more of a ferromagnetic object, a metallic film and a metallic foil.

摘要： An apparatus for determining a position between a wireless power transmitter and a wireless power receiver is provided. The apparatus comprises a ferrite structure. The apparatus further comprises a plurality of detection loops formed from metallic traces on a flexible printed circuit wrapped on or around the ferrite structure. Each of the plurality of detection loops comprises a solenoid detection loop. The ferrite structure comprises a first ferrite block and a second ferrite block disposed adjacent to the first ferrite block. A first wireless power transfer coil is wrapped on or around the first ferrite block. A second wireless power transfer coil is wrapped on or around the second ferrite block. Each detection loop of the plurality of detection loops is configured to sense an amount of magnetic flux flowing in a direction normal to a winding plane of the detection loop.
