Title: Mark Stuart Zahniser: Innovator in Vehicle Emissions Measurement
Introduction
Mark Stuart Zahniser is a notable inventor based in Lexington, MA (US). He has made significant contributions to the field of vehicle emissions measurement, holding a total of 3 patents. His work focuses on developing advanced systems for analyzing exhaust emissions, which is crucial for environmental monitoring and compliance.
Latest Patents
Zahniser's latest patents include an "Extractive sampling system and method for measuring one or more molecular species." This innovative system allows for the non-contact measurement of exhaust gas composition and fine particle composition from various vehicles under real operating conditions. The system extracts a sample of the exhaust plume through a sampling tube, utilizing a vacuum pump to transport it to a remote trace gas detection system. This method enables accurate emissions measurements away from the roadway, improving upon traditional 'cross-path' remote emissions sensing systems.
Another significant patent is the "Laser system for cross-road measurement of motor vehicle exhaust gases." This system employs tunable infrared laser differential absorption spectroscopy to analyze motor vehicle exhaust gases. By determining the absolute fractional absorption of a laser by the gaseous medium, the system calculates the absolute column densities of the gaseous species of interest. This technology not only enhances the accuracy of emissions measurements but also normalizes the concentration of the component of interest to the fuel consumption rate of the vehicle.
