  • Method and apparatus for plural document detection
    Patent number: 6212130
    Abstract: The presence of overlapped sheets on a paper transport is detected by employing such sheets as an acoustic interference filter. A beam of ultrasonic energy of appropriate frequency, angularly oriented to the planar transport path, will be attenuated to a much greater extent than the attenuation calculated based on the attenuation of a single sheet, as a result of destructive combining of wavefronts reflected from the facing surfaces of the overlapped sheets.
