First Claim
Patent Images
1. A system for quantifying the presence of one or more components in an exhaust plume of a vehicle traveling on a roadway, wherein the vehicle emits the exhaust plume in a generally vertical direction, the system comprising:
- a gathering structure having one or more surfaces that direct exhaust emitted by the vehicle to one or more openings of a collector disposed above the surface of the roadway; and
a flow generator in communication with the collector that is configured generate a flow of air that draws exhaust emitted by the vehicle in the generally vertical direction through the one or more openings of the collector to a component detection system that quantifies the presence of one or more components in the exhaust emitted by the vehicle.

11. A method of quantifying the presence of one or more components in an exhaust plume of a vehicle traveling on a roadway, the method comprising:
-
positioning a gathering structure above the surface of the roadway such that one or more surfaces of the gathering structure directs exhaust emitted by the vehicle as it travels on the roadway to one or more openings of a collector disposed above the surface of the roadway; and drawing exhaust through the one or more openings of the collector via suction; and analyzing the exhaust drawn through the one or more openings of the collector to quantify the presence of one or more components in the exhaust. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
