Remote sensor telemetering system

摘要: A telemetering system for remotely measuring a physical parameter of an object such as human or animal includes sensor device affixed to the including tuned circuit and sensitive coupled altering figure merit energy storage (Q) in response variations parameter, indicator unit transmitting signal intermittently ring energize with burst oscillating electromagnetic sense resultant reradiated generated by circuit. The measures rate decay sensed after end each transmitted measure Q microprocessor which generates then computes according prestored functional relationship between signal. computed is displayed display device. phase locked loop alter hence frequency be resonant may measured generating ratio peak voltage values sampled at two different but predefined times begins decaying.
