Latest Patents
One of his notable patents is the "Heat pump monitor apparatus for fault detection in a heat pump system." This innovative apparatus monitors a heat pump system to maintain a selected temperature in an enclosed space. It measures the run time for the heat pump compressor, ascertains the status of the heat pump reversing valve, and evaluates the run times of auxiliary heating units and defrost cycles. The system sends out an alarm signal when the heat pump fails to operate within expected parameters.
Another significant patent is the "System for stabilizing synchronous machines." This microprocessor-based power systems stabilizer operates through excitation control. It derives stabilizing information from sampled values of voltage and current taken from potential and current transformers. The system processes these values using algorithms to develop a stabilizing signal that provides the desired modulating action for damping machine oscillations in synchronous generators.
