Latest Patents

One of his latest patents is a technique for compensating for capacitive effects in conductivity. This innovation improves the accuracy in solution conductivity or resistivity measurement by utilizing a center-sampling technique. An AC drive is applied to a conductivity cell, and the voltage is sampled during a predetermined time interval in the center of a half-cycle drive waveform. The method compensates for cell capacitance, particularly the electrode-solution capacitive effects, by periodically sampling during a second time interval that differs from the first. This allows for a correction to the measured conductivity or resistivity, effectively compensating for capacitance-induced errors.

Another significant patent is a microprocessor-controlled constant current circuit. This apparatus generates a constant current and includes a storage device that holds a voltage corresponding to the constant current. The design features a resistor-capacitor filter, a Zener diode for supplying a constant voltage, and high off-state impedance devices that connect the Zener diode to the input in response to actuation signals. A microprocessor manages the timing of these signals, ensuring precise control over the current output.
