Abstract
Electrical safety apparatus for mobile machinery. Apparatus broadly comprises at least one sensor module, which has i) an E-field sensor plate configured to sample an E-field voltage gradient by means of capacitive coupling with an E-field proximate the sensor module; ii) a sensor processor arranged in signal communication with the sensor plate and configured to a. apply frequency discrimination to the voltage gradient; b. if the frequency discrimination satisfies a predetermined frequency range, apply amplitude discrimination to the frequency discriminated signal; and c. if the amplitude discrimination satisfies a predetermined amplitude threshold, generate a limiting signal. Sensor module also includes iii) a transmitter arranged in signal communication with the sensor processor and configured to transmit the limiting signal, and iv) an energizing arrangement configured to provide electrical energy to the sensor processor and transmitter. Apparatus also includes a controller having i) a receiver for receiving the limiting signal; ii) a memory arrangement; and iii) a controller processor arranged in signal communication with the receiver and memory arrangement and configured to in…
