First Claim
Patent Images
1. An apparatus for detecting an object, comprising:
- a coil configured to inductively sense a presence of the object based on an electrical characteristic of the coil that varies as a function of a temperature of the object when the object is exposed to an alternating magnetic field; and
a controller configured to detect a change in the electrical characteristic.
