Abstract
A batteryless sensor includes a small and concealed permanent magnet motor which operates as a generator to convert rotational or translational energy to an ersatz Vcc transient power supply via a mechanical arrangement to radiate a coded VHF oscillator signal to a repeater or central processing unit located as far as one mile from the sensor. The receiver is able to monitor a multiplicity of sensor units over a given time period.
