Introduction

David H. Tracy is a notable inventor based in Champaign, IL (US), recognized for his contributions to optical measurement systems. With a total of four patents to his name, Tracy has made significant advancements in the field of microfluidics and fluorescence detection.

Latest Patents

One of his latest patents is titled "Low Cost Optical High Speed Discrete Measurement System." This invention provides systems and methods for determining the velocity or inflation rate of a droplet in a microfluidic channel. The droplet is exposed to two or more temporally separated flashes of light, each flash including light of one wavelength band. The system is designed to image the droplet using a detector that can distinguish light in the wavelength bands. By acquiring two or more images of the droplet, each corresponding to one of the flashes, the system calculates the position or size of the droplet in each image. A velocity or inflation rate is then determined by dividing the change in position or size by the time allowed to pass between the flashes.

Another significant patent is the "Reduced Size Optical Coupler for Fluorescence Detection." This optical system is utilized for identifying an analyte, such as glucose in blood or interstitial fluid (ISF), using a biomaterial like glucose binding protein (GBP). The system includes a first filter that reflects light emitted from a light-emitting diode to illuminate a fluorescent body and transmits light emitted from the fluorescent body. Additionally, a second filter separates the light transmitted by the first filter into signal band light and reference band light.
