Introduction

Joanna Johnson is an inventor associated with Chaska, Minnesota, and Beckman Coulter, Inc. Her patent work addresses a method for evaluating fluidic substances by analyzing images of a container and the particles within the substance.

Latest Patents

The provided information identifies one patent associated with Johnson: “System and Method of Evaluating Fluidic Substance.” The method captures a reference image of an empty container and determines its grayscale value. After a volume of fluidic substance is aspirated into the container, a test image is captured and its grayscale value is determined. The reference and test values are then used to calibrate a universal curve relating grayscale values to particle concentration, allowing the concentration in the fluidic substance to be estimated. Johnson is credited with 1 patent.
