  • Non-contact envelope counter using distance measurement
    Patent number: 5221837
    Abstract: A counter for counting objects in a stack employs a beam moved by a scan carriage along an edge of the stack. A detector on the carriage determines the position of the portion of the beam reflected by the stack and determines, by optical triangulation techniques, the distance between the source of the beam and the edge of the stack. The resulting signal is used to recognize the presence of objects in the stack and to count them on the basis of this recognition.
