Detecting physical objects states using electromagnetic sensors

摘要

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. The position detection system further includes a translation mechanism for translating the object state into the first resonator position state and a computer system arranged to output an excitation signal at the predetermined frequency range to the first resonator and receive the first resonator position state that is associated with the resonator signal that is output from the first resonator in response to the predetermined frequency range.
