Abstract:
An apparatus for detecting a presence of an object includes an inductive sensing coil that is configurable to generate a magnetic field. The inductive sensing coil is configured to have an electrical characteristic that is detectable when generating the magnetic field. 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.
