Title: Ji Hyung Yoo: Innovator in Diagnostic Systems
Introduction
Ji Hyung Yoo is a notable inventor based in East Amherst, NY (US). He has made significant contributions to the field of diagnostic systems, holding a total of 3 patents. His work focuses on advanced technologies for measuring various parameters in fluid streams.
Latest Patents
One of Ji Hyung Yoo's latest patents describes a diagnostic system for measuring temperature, pressure, CO concentration, and HO concentration in a fluid stream. This innovative system includes one or more probes that sample the fluid stream spatially and temporally, accommodating a range of pressure and temperature. The design incorporates laser light sources directed down pitch optical cables, through a lens, and to a mirror, where the light is reflected back to catch optical cables. The light then travels through these cables to detectors, which provide electrical signals to a processor. The processor utilizes these signals to calculate CO concentration based on the temperatures derived from HO vapor concentration. Additionally, a probe for sampling CO and HO vapor concentrations is disclosed, featuring mechanical components that ensure proper alignment during assembly and use.
Another significant patent involves an EGR distribution and fluctuation probe based on CO2 measurements. This diagnostic system includes a laser, an EGR probe, a detector, and a processor. The laser is a swept-λ laser with a sweep range that includes a significant CO feature and regions of zero absorption. The processor determines CO concentration based on the detector's output signal and normalizes it according to the zero absorption regions. This system can utilize multiple EGR probes receiving light from a single laser, with the option of combining the light into a composite beam measured by a single detector.
