Abstract: An air treatment system includes at least one chamberless tube having air inlet and air outlet ends and a UV light reflective interior surface. The tube has an inside diameter and is preferably made from a UV grade aluminum. At least one tubular UV light source corresponding to the at least one chamberless tube is disposed generally coaxially within the UV reflective tube. The UV light source has an exterior light emitting surface spaced from the tube reflective interior surface. The light emitting surface has an outside diameter. Airborne pathogens in air moved through the tube and over the UV light source are eliminated.

Abstract: An upper control arm for a vehicle suspension system having a modulus section of hollow construction for reduced weight. The modulus section of the control arm is of a stamped and welded construction thereby eliminating material weight while reducing the cost of manufacturing. The modulus section has a substantially triangular configuration with a reinforced rim flange along the high compression stress area of the control arm elbow. The reinforced rim flange improves the strength of the control arm without sacrificing the weight reduction provided by the hollow construction.
