Title: David N DeMoura: Innovator in Predictive Instrument Maintenance
Introduction
David N DeMoura is a notable inventor based in Taunton, MA (US). He has made significant contributions to the field of predictive maintenance through his innovative patents. With a total of 2 patents, DeMoura's work focuses on enhancing the reliability and efficiency of sensor technologies.
Latest Patents
One of DeMoura's latest patents is a "Statistical trend generator for predictive instrument maintenance." This method adaptively schedules maintenance of a sensor by inferring the need for maintenance based on an error signal. This signal indicates a difference between a measurement signal generated by the sensor and an independently obtained reference signal. The correlation between these signals ensures that when the sensor is functioning properly, they will track each other over time. The method involves generating the error signal and monitoring it to detect a triggering event that indicates a mismatch, which suggests a potential malfunction in the sensor.
Another significant patent is the "Differential-pressure measuring apparatus with improved arrangement." This invention features a differential-pressure instrument with a sealed interior pressure chamber containing a fill-liquid. It includes flexible diaphragms that apply an input differential pressure to be sensed by an IC strain-gauge chip. The design incorporates a spring plate that divides the chamber and provides overrange pressure protection through a valve. This innovative approach ensures that the instrument can effectively measure high-span differential pressures while preventing damage from excessive pressure.
