Title: David W Hahn: Innovator in Particle Analysis and Flame Stabilization
Introduction
David W Hahn is a notable inventor based in Dublin, California, with a focus on advancements in particle analysis and flame stabilization technologies. He holds a total of 3 patents, showcasing his contributions to the field of engineering and science.
Latest Patents
One of his latest patents is a method for improving instrument response, which pertains to enhancing the accuracy of particle analysis under conditions of discrete particle loading. This invention addresses the challenges of low particle density loading, which can hinder uniform sampling. The technique involves separating laser sparks from sample particles and systematically gating the instrument response to improve the signal-to-noise ratio. By determining a threshold value for the intensity of a spectral line, the method classifies pulses as 'hits' to generate an averaged spectrum, ultimately determining the true metal concentration.
Another significant patent is a flame stabilizer for stagnation flow reactors. This invention stabilizes a strained flame by dividing it into equal-sized segments, which helps maintain stability and allows for higher film growth rates. The flame stabilizer consists of an annular ring with vertical pillars that increase the number of azimuthal nodes, preserving the necessary axisymmetric structure for stability.
