Abstract: Provided is an electrical connector (10) comprising supply side and load side housings (12) and (30 that are connectable by means of female socket (22) and male plug (32). The connector (10) includes an AC input (14) with input protection (18) for receiving an AC supply (16), a primary rectifier arrangement (20) configured to rectify the AC input (14) to a DC input, a female socket (22) having a single layer air-cored supply coil (24) sealed within the socket (22), and a capacitor arranged in series with the supply coil (24) to form a series resonant LC arrangement (26). Also included is a half-bridge resonant converter switched mode power supply arrangement (28) supplied from the DC input and driving the supply coil (24) to produce a symmetrical AC waveform, said converter configured with a switching frequency substantially matched to a resonant frequency of the series resonant LC arrangement.

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.
