Abstract: A document processing arrangement transporting sheets at a prescribed nominal speed along a track, terminated by sort-pockets, each with an associated diverter plus a guide assembly for guiding and driving a so diverted sheet into its pocket, the guide comprising an inject roll to accelerate the sheet, plus an arm assembly coupled to rotate with the roll and including an arm for guiding a so injected sheet toward its position in the pocket stack; this roll and arm assembly being arranged to rotate the arm away from its stack each time a sheet is entering, and also to be spring-driven to return the arm toward its stack.

Abstract: A method of processing documents involving: transporting the documents at high speed unidirectionally and without pause along a prescribed transport path past at least one image-lift site; scanning the entirety of respective document faces at the sites with illumination from a light-source; providing a light-guide along a path between the light-source and the sites; providing an energy-shaping gate, disposed at each of the sites and acting to channel the imaging illumination energy there; and providing a heat-dissipation stage disposed operatively adjacent the light source and acting to extract infra-red energy therefrom and dissipate it so as to shield the sites; this heat-dissipation stage comprising an infra-red extraction unit arranged and adapted to remove a substantial part of the infra-red energy projected along a prescribed beam-path from a high-intensity spectral source; the extraction unit comprising: a selective reflector interrupting the beam path and adapted to divert infra-red energy as an infra

Abstract: A method of providing a track-cleaning wand for use in a document handling machine having a track along which documents are transported past sensors separated by a distance d and recessed away from the side walls of the track, this wand including a rigid handle with, at one end, a rigid elongate spacer bar carrying a pair of like brushes spaced apart by the sensor separation-distance and having bristles long enough to reach the face of a sensor, when the spacer bar is swept along the track.

Abstract: A pair of data processing systems, each having a host CP and a controller, both systems to be operatively associated with a number of like memory units, each unit coupled to both controllers, wherein either host CP/controller can appropriate any "selected" memory unit by simply propagating "path-control-data" to memory in both controllers and in the selected memory unit.

Abstract: In a system for processing and imaging documents to develop a stream of digital, video bit sets, each related to a different document is a passing array, this system including an arrangement for simultaneously compressing a number of said bit-sets for different document images and sending the results to output, this arrangement as comprising:a preprocessing stage for distributing each said bit set in a pair, of like parallel bit-compression paths, one, a Master path for half the bits in a set, the other a Slave path for the other half as controlled by The Master, with both input to a common buffer, each compression path being adapted to execute a first compression and then a conditional second compression when certain initial factors are indicated and to provide a real-time-compressed output to this buffer; andboth said compressions being performed on a single, two pass stage of a Histogram/Compressor printed circuit board.

Abstract: In a multiprocessor computer system where a number of "agents" can compete for access to a "resource", a method of ameliorating "Livelock" and preventing any such agent from being unduly frustrated from such access, this method comprising: arranging the system to include an arbitrating unit and a common system bus connecting a number of processors, plus an Avoidance unit included in each processor and including a Random-Number generator and automatic "Random Backoff" that causes an agent that fails to secure access to wait for one or more given random time periods T.sup.B before reattempting such access, with each said time period T.sup.B being provided by the random number generator so as to likely differentiate from competing agents.

Abstract: An adapter arrangement for internetworking a non-CTOS computer means with a network of CTOS terminals, including a system-bus, this arrangement being adapted for introduction into, and cooperation with, the non-CTOS computer and comprising CTOS-net bus means for transferring signals from the system-bus plus a communication control stage for controlling and transferring signals to/from the CTOS network and a net-interface stage.

Abstract: Arrangement for lifting image of checks, with Xenon lamp, Fluorescent lamp or like source of stable-wavelength-output and CCPD Camera means selected to exhibit "close-to-human" spectral response plus a photopic filter, disposed upstream of the Camera and adapted to shift its received image-light spectrum in the direction of that which is optimal for the human-eye.

Abstract: Apparatus for transporting and processing documents and maintaining a preset nominal inter-document gap, g.sub.nom therebetween, this apparatus including atransport stage for picking each document from an input stack and advancing it toward a destination at a controlled rate; a sensor unit for sensing the distance g between the so-moved document and the following document; and a control stage for determining the variance .gradient.g, between g.sub.nom and g, while driving each successive document along a feed path from the input stack at adjustable times; with the sensor unit inputting the control stage which is adapted to responsively determine the variance-distance .gradient.g, and to thereupon control the transport stage to adjust the acceleration or deceleration of a following document and so tend to reduce this variance-distance .gradient.g.

Abstract: An electronic document-imaging arrangement which generates imaging-bits representing a given document and transfers these bits on a "per-document basis" to various successive electronic processing stages and, finally, to data base storage; this arrangement also including a tag unit adapted to create "sync-tag" bits unique for each such imaged document and transfer these tag bits, along with the imaging bits, for each document to each processing stage that handles the imaging bits on a per document basis, and finally to an associated interface for final matching and removal of the tag bits.
