Title: Innovations by Hollis C. Demmin

Introduction

Hollis C. Demmin is a notable inventor based in Tonawanda, NY (US). He has made significant contributions to the field of gas emission analysis and sensor technology. With a total of 4 patents to his name, his work has advanced the understanding and measurement of gas impurities and environmental variables.

Latest Patents

One of his latest patents is the "Gas emission spectrometer and method." This invention involves a gas emission spectrometer designed to analyze a continuously flowing gas stream. It utilizes gas emission spectroscopy to measure low concentration levels of one or more gas or vapor impurities. The device applies alternating power to an electric discharge source to generate emissive radiation, which is then filtered into an optical signal at the emission wavelength of a preselected impurity gas. The optical signal is converted into an electrical signal that is selectively amplified within a narrow frequency range, allowing for accurate measurement of impurity concentration.

Another significant patent is the "Neural network compensation for sensors." This method corrects the output from an electrochemical cell sensor, which responds to the concentration of sensed species in a stream, as well as pressure and temperature. The invention includes a pressure sensor and a temperature sensor that work together to process outputs in a neural network. This network compensates the electrochemical sensor for changes in pressure and temperature, providing a more accurate indication of the concentration of the sensed species.
