Latest Patents

One of his latest patents is the "Electronic current transducer for high voltage transmission lines." This invention includes a fast analog data channel that provides effective relaying information, stabilized by a slow, highly accurate channel that is insensitive to changes in gain. Additionally, for direct current (DC) transmission lines where polarity may reverse, offsetting or biasing allows for bipolar measurement. Another significant patent is the "Linear signal isolator and calibration circuit for electronic current." This optical data transmission system is designed for use with current sensors on alternating current (AC) high voltage transmission lines. It comprises a light-emitting diode transmitter at line potential and a silicon photodiode receiver at ground potential. Signals are conducted from the transmitter to the receiver along a fiber optic light pipe. A silicon photodiode in a feedback configuration produces a linear AC output light from the light-emitting diode in response to line current. A DC reference signal is superimposed on the AC current data signal to provide system gain calibration. The DC signal is utilized in a feedback loop to control the gain of an AC signal amplifier in the receiver, thus stabilizing system calibration.
