摘要： An imaging (e.g., lithographic) apparatus for generating an elongated concentrated scan image on an imaging surface of a scan structure (e.g., a drum cylinder) that moves in a process (cross-scan) direction. The apparatus includes a spatial light modulator having a two-dimensional array of light modulating elements for modulating a two-dimensional light field in response to predetermined scan image data, and an anamorphic optical system is used to anamorphically image and concentrate the modulated light onto an elongated imaging region defined on the imaging surface. To avoid smearing, movement of the imaging surface is synchronized by an image position controller with the modulated states of the light modulating elements such that image features of the scan image are scrolled (moved in the cross-scan direction) at the same rate as the cross-scan movement of the imaging surface, whereby the features remain coincident with the same portion of the imaging surface.

摘要： A method is provided for preparing a sample containing potential cells of interest and of using a laser of a laser based system for novel excitation and emission collection, and data usage including use of obtained data for direct and ratio based measurements. The prepared sample is configured to emit signals having spectral characteristics sufficient to permit filtering to differentiate and eliminate most false positives from true positives among acquired imaging events, in an imaging system employing a laser spot having a range of diameters from 1 to 20 μm or greater and which excites the fluorescence in a conventional or novel manner. These filtered events may be subsequently imaged and confirmed with another higher resolution device such as a fluorescent microscope in a short amount of time.

摘要： Xerox Reference No. D/A0639A system and method for improving xerographic halftoning by magnifying a threshold array, interpolating the in-between values, enabling multiple thresholds to be accessed simultaneously and presented to multiple comparators, to cause multi-bit output. A threshold array is sampled at distinct locations separated by the sparse sampling distance to allow warping of the threshold array dots by adjusting the sampling distance in small, fractional portions (deltas) of the magnified distance. By adding more thresholds, amplitude or intensity modulation is used to move dot edges in a process direction for further flexibility in printing irrational or warpable screens.

摘要： A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

摘要： The two symmetrical halves of halftone shapes that have a central axis of symmetry are selectively intensity modulated for accenting human readable information that is embedded in halftone patterns that are composed of halftone cells having fill patterns conforming to such shapes. This human readable information is defined by clustering these halftone fill patterns so that their accented portions visually blend to form alphanumeric character shapes.

摘要： A PDL or other type of line drawing program mathematically generates an edge between white and black regions. For curved edges, the edge is transformed into a plurality of piecewise linear edge segments (20). Pixels (u,v) in the vicinity of the edge are identified (12). Each pixel is assigned a magnitude value in accordance with its distance from the mathematically defined edge relative to a width or gray span (22) of the selected vicinity. The magnitudes in each of a plurality of subregions of the selected vicinity define a sloping plane (42). The threshold (t), such as a value mid-way between the extremes of the selected vicinity, defines a plane (44) which intersects the sloping plane. The line (46) of intersection defines the edge. A hyperacuity printer receives slope of the plane relative to a scan and orthogonal directions of the printer, and a magnitude for each pixel. Based on the slope and magnitude information, the printer determines (16) intensity and fast scan direction offset of a corresponding exposure value and prints (17) a corresponding dot.

摘要： A system for performing interlace scanning with plural light beams. The system includes a data source for supplying sequential lines of image data and a memory device for sequentially storing a plurality of the lines of image data, where the memory device has an input port for receiving the lines of image data from the data source. The memory device also has plural output ports where each of the plural output ports corresponds with one of the plural light beams. The system further includes addressing circuitry for addressing the memory device, where the addressing circuitry provides plural sets of slowscan output address signals corresponding to the plural output ports for providing an address value. The address value of each of the slowscan output address signals are offset from other of the address values by an offset amount provided by the addressing circuitry to enable interlacing of the plural light beams.
