Abstract: A vehicle includes a component coated with a pollutant reduction catalyst configured to remove pollutants from a flow of air over the component, a catalyst temperature sensor coupled to the component, a general temperature sensor, a vehicle speed sensor, and an active grille shutter (AGS) system having a plurality of movable grille shutters. A controller is configured to determine an efficiency of the pollutant reduction catalyst based on signals from the catalyst temperature sensor, the general temperature sensor, the vehicle speed sensor, and the AGS system.

Abstract: An illumination system having a lighting dome, a vertical light source, an image acquisition means, and a light controlling means, a system controller and a three-axis servo system wherein the dome is of unitary printed circuit board construction populated with a plurality of surface mounted light emitting diodes is disclosed. The dome has a first longitudinal axis and is bendable along hinges formed through the circuit board to define a partially enclosed dome having eight octants or sections, each section having an upper and lower tier portion defining a plurality of planar illumination banks, which illuminate an object from 360.degree. around the object and from predetermined angles relative to the first longitudinal axis. The vertical light source, which is a planar printed circuit board populated with surface mounted LEDs, and the beam splitter are provided for illumination of the object with light parallel to the first longitudinal axis.
