摘要： A document processing system including a digital image capture system, character recognition circuitry, document encoding systems, endorsers, audit trail printers and an in-line microfilm record system enable documents to be read, endorsed, encoded, digitally imaged, filmed and sorted in a single continuous pass through the document processor by way of a modular transport system. The encoding of the continuously moving documents is accomplished by a plurality of fixed dies, electronically controlled hammers, and an ink bearing ribbon interposed between the documents and the fixed dies, the ribbon being momentarily transported at the same velocity as the documents. Scanning and digitizing of the documents is effected by continuously transporting the documents across the focal plane of a stationary scanner where the documents are repetitively scanned in a single axis, two scanners being employed to permit scanning and digitization of both sides of a particular document in a single pass through the transport mechanism. Circuitry is included in the scanner which permits the presence or absence of a document to be detected and allows dynamic adjustment of threshold levels, thereby accomodating documents which utilize shaded backgrounds. The system includes apparatus for visually displaying an image which corresponds to a plurality of stored digital values, the apparatus including an image memory and circuitry enabling the display to be partitioned into discrete portions of variable sizes, each portion of which may be utilized either to display a selected portion of the image within the image memory or to display a plurality of alphanumeric characters. Additionally, circuitry is provided which allows image rotation, mirror imaging and discrete video attribute selection within each portion of the display. Video data compression apparatus and method are employed for use in minimizing the amount of data necessary to store and recall a black and white video image. An image initially obtained by vertically scanning a selected document is represented by a series of consecutive vertical scans identifying particular sections or cells of the image as black or white. A plurality of consecutive scans are then temporarily stored and analyzed horizontally, analysis circuitry being utilized to identify certain consecutive black or white sections of the image, repetitions of previous sections of the image or repetitions of certain selectable patterns within the image. The coded output of the analysis circuitry is then stored and utilized to reconstruct the image.

摘要： A hand held scanning device (20) has a sensing unit (26) consisting of a first linear array (30) of light emitting diodes (LEDs) (32) spaced from and parallel to a second linear array (34) of photosensitive element integrated circuits (36). The LEDs (32) and integrated circuits (36) are mounted on a common substrate (60) facing an opening in bottom surface (24) of housing (22). A roller (28) is parallel to the sensing unit (261. A wheel (82) containing light and dark areas is positioned to be rotated by the roller (28). The roller (28) assures that the scanning device (20) travels in a straight line path when it is moved along a sheet of paper. The light and dark areas of the wheel (82) are sensed to define line scans of the device (20) and uniform light exposure by the LEDs (32) on the basis of distance travelled along the sheet of paper. A tight collimating fiber optic plate (67) is positioned over each integrated circuit (36).

摘要： The output (18) from an optical sensor is recharged for a time dictated by the output of the digital-to-analog converter (11). A previous count indicative of the recharge time is stored in memory (52) which controls the converter (11). This count is manipulated in incrementing circuit elements (54) depending on the time the comparator (12) signals a difference signal, indicative of a period of recharge.

摘要： @ A radiation image read-out apparatus comprises a stimulating ray optical system for exposing a stimulable phosphor carrying a radiation image stored therein to stimulating rays, a photodetector for detecting light emitted by the stimulable phosphor upon exposure to stimulating rays, and a light guide member for guiding the emitted light to the photodetector. A dichroic optical plane which selectively reflects either the stimulating rays or the light emitted by the stimulable phosphor and selectively passes the other is positioned in an optical path or the light guide member. The stimulating ray optical system is positioned so that the stimulating rays directly impinge upon the dichroic optical plane and come out of a light input face of the light guide member positioned close to the stimulable phosphor by being reflected by or passed through the dichroic optical plane. The light input face of the light guide member is preferably provided with a film for preventing reflection of stimulating rays.

摘要： A system for identifying a bar code label affixed to a rod wherein the bar code label including each bar thereof generally circumferentially spans on the rod an angle (the bar code angle) greater than 180° and less than 360° about the rod's longitudinal axis. The system includes a bar code reading optical scanner and a rod positioning mechanism. The scanner has a light beam from a single source and creates two scanning lines which superimposingly intersect at an angle which is greaterthan 360° minusthe bar code angle and which is less than or equal to 180°. The rod positioning mechanism co-linearly (or close enough to such) aligns the rod's longitudinal axis with the intersection line of the scanning lines so that the bar code label may be identified independent of the rotational position of the rod about its longitudinal axis.

摘要： The holographic scanner includes a rotating glass disk (20) having an annular track of sectorial holographic diffraction gratings or holofacets (22) for deflecting an impinging laser (24) beam along arcuate scan lines. The beam which sweeps along these scan lines is redirected by beam folding mirrors (30), to create specific scan patterns focused in predetermined regions (36,38) adjacent a scanner window (32). Similar or dissimilar scan patterns can be generated depending upon the characteristics of the holofacets (22) and the placement of the beam folding mirrors (30). The scan patterns can be focused at different distances from the scanner window (32) to increase the size of the "gate" through which a label must pass in order to be successfully scanned. The returning light is focused by a lens (40) onto a photodetector (42) which generates an electrical signal proportional to the reflected radiation amplitude.

摘要： Zum Erkennen von strichförmigen Markierungen bei einer Relativbewegung zwischen den Markierungen und einer optoelektronischen Abtasteinrichtung ist die opto elektronische Abtasteinrichtung mit zwei in Abtastrich tung geringfügig gegeneinander versetzt angeordneten Abtastern (A1, A2) versehen. Die Ausgangssignale (AB1, AB2) der Abtaster (A1, A2) liegen einerseits an einer Differenzsignale (DI) erzeugenden Differenzstufe (D) und andererseits an einer Summensignale (SU) erzeugenden Summierstufe (S) an. Wenn ein Summensignal (SU) auf tritt und gleichzeitig ein Differenzsignal (D) einen Null durchgang aufweist, erzeugt eine Auswertestufe (AW) ein der Markierung zugeordnetes Signal.
