Abstract: An apparatus and method for evaluating window transmission loss comprising taking a plurality of photographs through a filter of a window to be evaluated, determining a percentage of the window shown in each photograph that is undamaged, and computing an estimate of transmission loss for the window from the percentages determined.

Abstract: The present invention is directed to recording changes associated with the acceleration of a structure. An exemplary embodiment includes an accelerometer array having at least one silicon beam type accelerometer, a nonvolatile memory, a clock timer, a programmable control unit operatively coupled to the accelerometer array, at least one non-volatile memory, and clock timer. The accelerometer array, the at least one non-volatile memory, the clock timer and the programmable control unit can be formed on a common semiconductor substrate (e.g., integrated), with the accelerometer array disposed in a central region.

Abstract: A belt tensioning system for a belt transport particularly adapted for use in a document handling system of a reproducing machine. A belt is arranged for movement about first and second pulleys which are adjustably supported within a frame. The frame includes a tensioning system for adjusting the tension of the belt by changing the relative distance between the pulleys. The tensioning system includes a vernier for providing fine adjustment of the belt tension. The vernier system allows the belt tension to be adjusted while maintaining the parallelness of the belt pulleys.
