Latest Patents

Richards’ latest patents showcase his expertise in developing advanced electrical components. One notable invention is the **Photoelectric Auxiliary Switch for Electromagnetic Contactor**. This innovative device incorporates photoelectric reflective object sensors mounted in an auxiliary switch case, which detects members on a movable contact assembly of the contactor. It produces logic level output signals that indicate the operational state of the contactor's electromagnet. The use of one or a pair of photoelectric sensors in side-mounted auxiliary switches allows for the detection of the movable contact assembly during its energized or de-energized states. Furthermore, a single photoelectric sensor detects the extended position of the assembly in top adder configurations.

Another groundbreaking patent is the **Frequency Selective Arc Detection** method and apparatus. This technology is designed for electric circuits with electrified conductors linking a voltage source to a load. A field sensor identifies an electromagnetic field generated by electrical arcs in the circuit and produces a field responsive signal. The arc discrimination circuitry utilizes frequency responsive technology to interpret the field signal, generating an arc indicative signal based on specific frequency characteristics. This innovation enhances circuit safety by efficiently detecting electrical arcs.
