Title: Innovations by Michael A. Potter

Introduction

Michael A. Potter is an accomplished inventor based in Wilderville, Oregon. He has made significant contributions to the field of particulate monitoring instruments, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the "Twin-spot light absorbing particulate monitoring instrument." This apparatus comprises one or more pairs of analyzers that measure light-absorbing particulates, including black, brown, and ultraviolet light-absorbing organic aerosols suspended in gaseous samples, such as air. One analyzer receives an ambient gas sample, while the other analyzer is coupled to a dilution inlet that mixes ambient gas with a proportion of clean gas. This setup allows the two received samples to have different particulate concentrations. Filters with identical filter areas accumulate particulates as the respective samples flow through with equal flow rate and velocity. An optical source and detector for each filter measure a changing property, such as attenuation at one or more wavelengths, as particulates accumulate. A computer uses the differential particulate accumulation from the ambient and diluted samples to compensate for filter loading effects upon the measurement, providing an accurate indication of particulate concentration in the ambient sample.

Another notable patent is the "Nephelometer with concentration-modulated sample flow." This nephelometer is designed for detecting the concentration of particulates in a sample aerosol. It features a branched flow path with a sample aerosol input, a clean gas input, and an output leading to an optical sensor unit. At least one of the inputs has periodic variable flow, supplying a concentration-modulated gas stream to the optical sensor unit. The detector output of the sensor unit is processed in synchrony with the concentration modulation to filter out DC components, such as 1/f noise and parasitic instrument noise.
