Latest Patents

One of her latest patents is a time division multiplexing amplifier. This innovative amplifier features a differential amplifier, such as a dynamic bridge amplifier, which provides a predetermined gain accurately through operational network resistors. The differential amplifier is designed to amplify differential signals that contain a common-mode voltage. Before amplifying these signals, a common-mode voltage is applied to the two input terminals of the differential amplifier, allowing for precise adjustments to achieve a zero offset voltage. This ensures that the differential signals can be amplified without the adverse effects of common-mode voltage.

Another significant patent by Horinaka is a method for measuring analog input voltages through isolation transformers. In this method, an analog input voltage is applied across the primary winding of the isolation transformer. The voltages developing across the secondary winding are detected over specific time lapses. By utilizing the measured times and secondary winding voltages, the analog input voltage can be calculated, compensating for any sag due to the isolation transformer.
