Title: Innovations of David M Stern
Introduction
David M Stern is a notable inventor based in Merion Station, PA (US), recognized for his contributions to the field of signal processing and instrumentation. He holds a total of five patents, showcasing his innovative approach to solving complex engineering challenges.
Latest Patents
One of his latest patents is the "Error Compensating Instrument System with Digital Communications." This instrument system provides compensation for signal processing errors by processing both sensor signals and reference signals in a common signal processor. The system outputs compensated signals to a two-wire signal loop in either analog or digital form, selecting the output signal format based on digital input signals received from the signal wires. This system can be embodied as a radio frequency admittance instrument system for monitoring the condition of materials.
Another significant patent is the "Two-Wire Compensated Level Measuring Instrument." This improved system generates a signal representative of the level of a material with a dielectric constant within a vessel. It features a first probe that generates a signal indicative of the dielectric constant of the material, which is then divided into a signal varying with the level of the material. This design ensures that a compensated level signal is measured irrespective of the actual dielectric constant. The instrument operates in a two-wire system with low power requirements, enhancing reliability and accuracy.
