Abstract: The test range is provided with a calibration system for calibrating the exact position of a light curtain formed by a ballistic screen. The calibration system uses a model ball which can be moved through a light screen at high speed in order to simulate the actual passage of a driven golf ball through the light screen. Positioning of the model golf ball at a point at which the golf ball just contacts the light screen serves to determine the exact location of the light screen. A laser ranging device is used to locate the calibration system relative to a launch point. Thus, the precise distance of the curtain of light from the launch point can be readily determined. The calibration system may also be used to determine if a ballistic screen is mounted in a true vertical plane.

Abstract: The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter, the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding measurements or directly to an output station. During grinding of one wafer, a second wafer may be held between the measuring station and the grind station while a ground wafer is moved from the wash station to the measuring station for after-grinding measurements.
