Abstract: A system includes a tire inspection station configured to inspect a tire of a tire wheel assembly. The tire inspection station includes a lifting assembly configured to lift and rotate a tire wheel assembly disposed in the tire inspection station, movable centering arms adjustably positionable to center a hub of a tire wheel assembly relative to the lifting assembly, and top and bottom camera assemblies configured to image sidewalls of the tire wheel assembly when it is lifted. The system further includes software configured to process images from the camera assemblies and display results of the processing. The system additionally includes a wheel inspection station comprising a camera. The system further includes software configured to process images from the camera to verify wheel properties.

Abstract: A new acoustic insulating sheet material comprises in laminar assembly a) a primary sound absorbing sheet, and b) a dense porous membrane that i) has an air-flow resistance of about 5000 rayls or less and ii) has an Acoustic Value Ratio as defined herein of at least 3000. Preferably, the membrane is about 200 micrometers or less in thickness, and more preferably is about 150 micrometers or less in thickness. Also, the Acoustic Value Ratio is preferably at least 7,000. The described membrane can also be used alone to acoustically insulate a space, e.g., by mounting it in planar array over an air gap and in position to attenuate noise from a noise source.
