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.

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 and detect an attenuation in the first resonance signal over time to detect a change in the object wherein the controller is configured to control an amount of energy of the first resonator, a magnitude of the first resonance signal, and the range of the field of the first resonator based on the noise component of the first resonance signal.
