Abstract: A sun screen includes a plurality of sections adapted to assume a generally planar configuration when extended and a compact configuration when folded in an accordion-like manner. Adjacent sections are coupled in a hinge-like manner by linear arrays of perforations to facilitate folding of the sun screen, which may then be retained in the folded configuration by an elastic strap disposed thereabout. An upper, median portion of the sun screen includes a narrow slot extending downward from an upper edge along the center, linear array of perforations and terminates in a circular aperture. A second plurality of linear arrays of perforations are disposed radially about an upper portion of the aperture, terminating in the upper edge of the sun screen. The circular aperture is adapted to receive a rearview mirror support member mounted on or adjacent to the windshield by inserting the mirror support through the aforementioned slot.

Abstract: An imaging system for detecting recombination center defects in a semiconductor wafer in which an oxidized wafer is pre-treated by charging the oxide in a corona discharge and then passing the charged wafer below a stationary bifurcated electrode. A focused laser beam is scanned between the arms of the bifurcated electrode and along its length as the wafer is slowly moved transversely to the direction of laser scanning. The signal from the bifurcated electrode is displayed in an imaging system, one axis of which is synchronized to the laser scanning and the other axis is synchronized to the movement of the wafer.
