Latest Patents

One of his latest patents is titled "Method and apparatus for auto-calibration of signal conditioning." This invention allows numerous signal conditioning circuits on multiple printed circuit boards to be calibrated remotely by a signal processing unit. The unit sends coded signals to each board, either sequentially or in parallel, to connect test signals to the conditioning circuits. The processing unit utilizes the actual and expected responses of each circuit to generate a gain and an offset, which are applied to provide a calibrated signal. Additionally, the time constant for each circuit is measured periodically to ensure valid data is obtained following signal transfers.

Another significant patent is the "Frequency compensated differential amplifier." This invention addresses the challenges faced in differential input DC gain amplifiers with high input impedance. It incorporates a capacitive attenuator to reduce the amplifying effect on the AC component caused by industrial power line interference. The design feeds back the AC signal through cross capacitors, ensuring that the ratio of the differential outputs to the differential inputs for the AC component remains substantially unity.
