Assignee: LIFE DETECTION TECHNOLOGIES, INC.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 9:
10. A method comprising:
establishing, by an electric field generator, an electric field around a desired area of detection that includes a body being monitored, the electric field generator comprising an oscillator oscillating at a frequency; and
detecting, by a demodulator coupled to an output of the electric field generator, a change in a frequency of the generated electric field around the desired area of detection, wherein the detecting comprises multiplying 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;
wherein characteristics of the body being monitored cause the change in the frequency of the generated electric field around the desired area of detection.
