His work focuses on enhancing the efficiency and functionality of monitoring equipment used in various applications.

Latest Patents

One of his latest patents is a "Portable Test Receiver for Remote Monitoring System." This innovative apparatus is designed for field maintenance of remote sensor monitoring systems for underground transformers. It utilizes a phase-locked loop method to demodulate the DPSK modulation of the remote monitor transmitter. The device is battery-operated, allowing for easy mobility to monitor critical locations and spot networks during maintenance work. It features a single software-driven display that offers good visibility while maintaining low current drain. The decoding of the transmitter signal is achieved by using the crystal oscillator circuit of the transmitter to generate a reference, which is then compared to the transmitter signal to detect phase flips.

Another significant patent is the "Remote Monitoring System Receiver with Dual Baud Rate Selector." This receiver operates at a dual baud rate, which can be selected to match the rate used by the remote equipment originating the data link. A modem associated with the receiver provides an indicator signal that indicates whether phase shift keying (high baud rate) or frequency shift keying (low baud rate) is being received. This indicator signal is crucial for selecting the baud rate of a programmable baud rate generator within the RMS receiver, controlling the data transfer between the receiver and the modem.
