Title: Innovations by James W Thomson

Introduction

James W Thomson is an accomplished inventor based in Murrysville, PA (US). He holds a total of 2 patents that showcase his expertise in the field of analytical instrumentation. His work primarily focuses on developing advanced diagnostic methods and apparatuses that enhance the accuracy and efficiency of gas analysis.

Latest Patents

One of his latest patents is titled "Diagnostic method and apparatus for solid electrolyte gas analyzer." This invention features a solid electrolyte gas analyzer equipped with a diagnostic circuit that intermittently measures the impedance of the solid electrolyte measurement cell. This measurement serves as an indication that the cell may require calibration or replacement. The diagnostic operation is performed in situ, meaning the solid electrolyte cell is exposed to the gas being measured while heated to a controlled elevated temperature. The cell impedance is measured at a predetermined frequency by injecting a modulated current through the cell and measuring the resulting voltage drop.

Another significant patent is the "Chemical species optical analyzer with multiple fiber channels." This analyzer is designed to measure properties of multiple chemical samples. It includes an optical filter element positioned where simultaneous multiple light beams, corresponding to the chemical samples, form a diffuse light spot elongated along an axis that aligns with the filter element's long axis. The analyzer also incorporates a light source, filter means with the filter element for transmitting spectrally selected portions of the light beams, and sample cell means for exposing each sample to its associated light beam. Additionally, detector means are included for detecting the light beams after they have been modified by the samples and transmitted by the filter.
