  • Patent number: 5921523
    Abstract: An arrangement for mounting a computer unit and a camera unit securely on a flat support: I.E., acamera mount including a shaft/fixture unit for receiving the camera to be adjustably positioned thereon; andplanar base to be affixed to said support for engaging the bottom of the computer unit with a pair of computer-enclosing sides coupled to the base, withone side including a top portion for engaging the top of the computer and one side adapted to mount the shaft.
    Type: Grant

  • Patent number: 5758916
    Abstract: Disclosed is a probe implement for removing jam debris, including documents, and foreign objects from prescribed document transport track segments of a document processing machine; this implement being constructed of planar, flat elongate thin dielectric material, and being so formed, shaped and constructed as to allow a user to remotely contact and engage such documents, debris or foreign objects and to facilitate removal thereof from the track without disturbing, opening or demounting this track; this implement being further designed, constructed and adapted to be sufficiently flexible in such use to be maneuvered along track segments, to be sized to readily fit into the minimum contemplated track size, while being sufficiently stiff to engage/dislodge such debris.
    Type: Grant
    Filed: November 4, 1996
    Date of Patent: June 2, 1998
    Assignee: Unisys Corp
    Inventors: Thomas L. Raupp, J. Michael Spall, Kimberly A. Gearns
  • Patent number: 5671919
    Abstract: An apparatus for differentiating and separating multiple overlapped like documents from single like items, transported along a track comprising a suction device applying opposed vacuum forces to separate the documents at a separation station. Measuring and analyzing the resulting pressure differentials within the suction system by a pressure sensor to indicate whether single or multiple documents are passing.

  • Patent number: 5509648
    Abstract: A method for differentiating and separating multiple overlapped like documents from single like items, transported along track means, comprising: subjecting the documents to opposed vacuum forces from suction means to separate them at a separation-station; then determining whether the documents are single or multiple, by measuring and analyzing the resulting pressure differentials within the suction system; using a cyclonic filter for removing and storing dust and debris entrained within the suction-conducting airflow, the cyclonic filter and suction system being designed and adapted to provide a relatively constant vacuum-generating airflow regardless of the nature of quantity of debris removed; plus a pressure sensor for indicating whether one or several documents are passing.

  • Patent number: 5439506
    Abstract: In a check processing apparatus, a technique for separating multiple checks from single like items, these transported along a track wherein the checks are first subjected to twin opposed vacuums to separate them; their state (whether single or multiple) is then determined by measuring and analyzing the resulting pressure differentials within the vacuum-generating system; which is, in turn, provided with a cyclonic filter/suction pump for removing and storing dust and debris entrained within the vacuum-forming air flow, this cyclonic pump providing a constant vacuum-airflow regardless of the nature or quantity of debris removed and collected; the system being also provided with pressure sensor(s) to indicate whether (single or multiple checks are passing, plus a fail-safe unit to warn of vacuum failure. A pressure sensing unit is further provided with a variable damping stage to mask-out minor, insignificant pressure fluctuations.

  • Patent number: 5437375
    Abstract: A method for on-the-fly detection and separation of multiple checks or like documents transported in a track, wherein the documents are first subjected to twin opposed vacuum forces from a suction source, to separate multiple documents; then a measuring and analysis of the resulting pressure differentials is taken within the vacuum-forming system; the system being provided with a cyclonic filter-separator upstream of the suction source, for removing and storing dust and debris entrained within the vacuum-forming air flow; the cyclonic filter-separator being designed to provide constant vacuum-forming airflow regardless of the nature or quantity of debris removed and collected; the system also being provided with a pressure sensor to give clear indication of the separated/unseparated state of the passing documents, and to exhibit a variable damping accessory.
