Title: Innovations by Santhi E Mathew
Introduction
Santhi E Mathew is a notable inventor based in Londonderry, NH (US). He has made significant contributions to the field of pressure transducers, holding a total of 5 patents. His work focuses on enhancing the functionality and reliability of pressure sensing technologies.
Latest Patents
One of his latest patents is titled "Constant power dissipation in capacitance pressure transducers." This invention describes a system and method for maintaining power dissipation substantially constant across the sensor interface board of a capacitance pressure transducer. It includes a shorted diaphragm level detector that identifies when the diaphragm shorts onto reference electrodes. A power dissipating resistor is strategically placed near the oscillator that drives the capacitance detecting circuit. When a shorting event is detected, the resistor is switched across a power supply, allowing current to flow through it. This mechanism ensures that power can be added sufficiently to maintain constant power dissipation by the oscillator during shorting events.
Another significant patent is "Multi-temperature heater for use with pressure transducers." This invention features a heater that includes two heating elements, each characterized by different electrical resistances. The design allows for accurate heating of a pressure transducer to at least four different operating temperatures. This is achieved by selectively connecting the heating elements to the transducer temperature control circuitry in various configurations.
