1. A detecting apparatus comprising:
- a first resonator configured to generate a first resonance signal based on power output from a power supply in response to an object changing within a range of a field of the first resonator;
a switch configured to connect the first resonator to the power supply in response to a control signal; and
a controller configured to sample a value of an envelope of the first resonance signal to detect a change in the object.

Abstract
A detecting apparatus includes a first resonator configured to generate a first resonance signal based on power output from a power supply in response to an object changing within a range of a field of the first resonator, a switch configured to connect the first resonator to the power supply in response to a control signal, and a controller configured to sample a value of an envelope of the first resonance signal to detect a change in the object.

15. A method of detecting a change in an object, the method comprising:
-
connecting a first resonator to a power supply in response to a control signal; generating, using the first resonator, a first resonance signal based on power output from the power supply in response to the object changing within a range of a field of the first resonator; and sampling a value of an envelope of the first resonance signal to detect a change in the object. - View Dependent Claims (16, 17, 18, 19, 20)
