  • Detecting physical objects states using electromagnetic sensors
    Patent number: 6417663
    Abstract: Disclosed is a position detection system for determining a state of a physical object. The position detection system includes a platform and a physical object positioned adjacent to the platform. The physical object has an object state that is changeable. The position detection system also includes a first resonator having a first resonator position state. The first resonator is arranged such that a change in the object state causes a change in the first resonator position state and such that the first resonator position state is different from the object state. The first resonator is further arranged to output a resonator signal that is associated with the first resonator position state when an excitation signal with a predetermined frequency range is received by the first resonator.
