Title: Brian J Shahan: Innovator in Particle Counting Technology

Introduction

Brian J Shahan is a notable inventor based in Grants Pass, Oregon, who has made significant contributions to the field of particle counting technology. With two patents to his name, Shahan has developed innovative solutions that enhance the accuracy and efficiency of particle detection.

Latest Patents

Shahan's latest patents include a "Condensation nucleus counter having vapor stabilization" and a "Condensation nucleus counter employing supersaturation by thermal." The first patent describes a particle counter of the condensation nucleus type, where a primary stream of fluent material containing particles is enlarged by vapor condensate of a working fluid. This primary stream flows through a viewing volume, while a secondary stream, known as purge gas, surrounds it to reduce turbulence. The two streams merge after passing through the view volume, and the merged stream is drawn into coalescent filters for recycling the working fluid, thus extending its life and preventing environmental contamination. The second patent features an entropy control mechanism that regulates the entropy of a vaporized fluid in a saturator, facilitating supersaturation around particulates in a sample gas stream before it passes through a condenser. This design includes a supply of sample gas, conduits, a saturator, a condenser, and an optical detector, all in fluid communication, ensuring efficient particle detection.
