Classification: CPC A  G | IPC A  G

Claim 0:
1. A system comprising:
an electric field generator comprising an oscillator oscillating at a frequency, the electric field generator establishing an electric field around a desired area of detection that includes a body being monitored;
a demodulator coupled to an output of the electric field generator and outputting a signal indicative of a change in a frequency of the generated electric field around the desired area of detection, wherein the demodulator multiplies the output of the electric field generator by a phase-shifted version of the output of the electric field generator, the phase-shifted version of the output of the electric field generator being generated by a resonant circuit; and
wherein characteristics of the body being monitored cause the change in the frequency of the generated electric field around the desired area of detection.
