Latest Patents

Hanson holds a patent for "Systems and methods for determining compliance of moving vehicles with an emission-concentration monitoring system." This patent describes a system that includes first and second monitor stations separated by a sensing space along the path of a moving vehicle. Each station is equipped with a source of electromagnetic radiation directed through the vehicle's exhaust plume. Detectors at each station measure transmittances at wavelengths absorbed by various molecular species in the exhaust plume, such as hydrocarbons, nitric oxide, carbon monoxide, and carbon dioxide. The data processor converts these transmittances into emission concentrations, which are then compared to established emission-concentration standards. A vehicle is deemed in violation only if its emission concentrations exceed the standards at both monitoring stations. The system also incorporates video cameras and a license plate reader to ensure visual identification of the vehicle, enhancing testing accuracy by providing a check against errors due to vehicular temporal variabilities.
