Abstract: A color printer control system comprising a user interface for shifting color hue. A control panel display includes an illustrative representation such as a color spectrum bar for suggesting a color range for both the input document and the output document. The user interface has a selective control such as a slide bar including an indicator of a user preference relative to the color reference bar. The position of the slide bar represents the hue shift input by the user. A dynamic image representation, such as a photograph, concurrently adjusts its hue in accordance with adjustment of the color slide bar and the user command. The dynamic image shifts color hue to provide a more accurate indication of the effects of hue shift to the user.

Abstract: This invention provides a scheduling scheme that uses an estimated rasterization execution time (RET) to improve the productivity of printers, particularly color printers. Because print jobs have different levels of complexities, a longer RET may be require for some jobs than for others. For example, a print job which includes color graphics, color print, different font changes or a variety of style formats such as, italic, bold and other styles, will have a longer RET than a simple black and white print job. If a print job is pre-scanned to estimate the RET before the print job arrives at the printer, it is possible to schedule those print jobs with a shorter RET ahead of those print jobs with a longer RET, thus improving productivity of the printer.

Abstract: A parallel duplex paper path device is provided for feeding a recording medium along a feed direction from a first printing device to a second printing device, which are arranged in parallel. The paper path device comprises at least two turning stations that are each assigned to one of the first or second printer. The turning stations are configured symmetrically to allow for reversing the feed direction and to allow for a device which can be assembled using standardized sub-assemblies.

Abstract: Gallium nitride substrates are formed by etching a gallium nitride layer on a sapphire substrate or by selective area regrowth of a gallium nitride layer first deposited onto a sapphire substrate. The gallium nitride layers are bonded to a support substrate and a laser pulse directed through the transparent sapphire detaches the gallium nitride layers from the sapphire substrate. The gallium nitride layers are then detached from the support substrate forming freestanding gallium nitride substrates.

Abstract: A dual III-V nitride laser structure has a thick current spreading layer on a sapphire substrate and a trench extending into the current spreading layer to reduce thermal cross-talk between the dual lasers.

Abstract: In a display element in which three or more display layers for displaying mutually different color lights are stacked within one pixel and which controls display states of the plural display layers by applying a voltage from the outside of the plural display layers, eight colors—white, black, blue, green, red, cyan, magenta, and yellow—can be displayed within one pixel. Display layers having cholesteric liquid crystals selectively reflecting blue, green, and red lights are stacked between a pair of substrates, and a light absorption layer is formed on the back of the substrate of a non-display side. Threshold voltages of orientation change of the display layers are mutually changed, and a threshold voltage Vpf90(A) of change from a planar state to a focal conic state of the display layer having the highest threshold voltage is made higher than a threshold voltage Vfh90(C) of change from a focal conic state to a homeotropic state of the display layer having the lowest threshold voltage.

Abstract: A document image capture (scanning) system and control method are described for scanning and processing document images received live from a camera. A motion detector detects image motion between two image frames. When the image is stationary, image processing (such as OCR) is carried out automatically and made available to the operator. In one form, when movement is detected, the image processing results are discarded until the image is newly stationary, whereupon new image processing is carried out on the new image. In another form, the degree of movement is evaluated; if the movement is small, then at least some of the previous image processing results are re-used by re-mapping on to the new image.

Abstract: In high speed reproduction apparatus in which closely spaced printed sheets are sequentially fed downstream in a sheet path at a process velocity, a dual inverter system of two independent but cooperative sheet inverters is sheet control gated to receive alternate sheets from the sheet path for inversion in the alternate independent sheet inverters. These dual alternate sheet inverters may advantageously operate at substantially the same sheet velocity as the connecting sheet path, instead of the much higher speed and acceleration/deceleration typical of conventional single inverter systems. This enables less critical higher speed cut sheet handling and thus more reliable faster printing. Yet collated sequential sheet order is maintained. This dual inverter system may be an integral part of a duplex path to provide inversion of sheets for duplex printing of their other sides.

Abstract: One image forming/capture device feature is the ability to finely control image quality response curves. To enable fine control, the user defines a number of points to which the response curve is to be fit. The response curve is fit to or through these points. However, users have trouble appreciating the effects of this adjusted response curve in converting input image values to output image values. The response curve control graphical user interface allows the user to finely control a response curve of an image quality for an image forming/capture device in an intuitive manner, by providing a plurality of slider portions that allow the user to more intuitively control the image quality response curve. These slider portions mimic control elements of conventional photocopier control panels. Each slider corresponds to a point, or a range of points, of the response curve. The slider portions are arranged so that the points associated with each slider portion are arranged in an easily understandable order.

Abstract: It is desired to remove matter on a fluid surface of a tank. The tank defines a circular tank orifice comprising a tank orifice rim, the tank orifice rim containing a fluid surface of a fluid, the fluid overflowing the tank orifice rim to form a fluid overflow, the fluid surface defining a fluid surface center. The matter is removed by discharging from near the tank orifice rim a plurality (n) of jets of the fluid towards the fluid surface center. Any matter on the fluid surface is thereby urged toward the tank orifice rim and eventually removed from the fluid surface by the fluid overflow. In one application, the tank comprises a dip tank and the fluid comprises photoreceptor coating solution or components thereof such as solvents, additives, or both.

Abstract: Certain types of digital printers are susceptible to the deletion of image data toward the edge of print sheets of certain sizes. To avoid deletion of significant image information, an interpreter associated with a printer can reduce and translate each printed image slightly, to cause the printed image to be “shrunk away” from edge areas on the print sheet. A program associated with the interpreter reads the header of a job submitted thereto, and determines whether this image reduction is desirable, based on the identity or type of a source computer submitting the job.

A method for making the toner includes the surface treatment of the toner with a water-soluble silicate.

Abstract: A method and apparatus for prioritizing the use of multifunctional printing system's basic processing resources to multiply active capability job resources for a basic resource under a certain condition. The printing system employs a controller with an improved job contention manager (JCM). A plurality of basic resources of the printing system are provided with a queue. One or more job services, at desired times, signals the JCM to carry out a sub-job of a given job. The signal for each of the sub-jobs includes information about the respective sub-job and its job service and priority. Responsive to the signal, the JCM adds, for a first video capability required by a first sub-job, a corresponding first basic job resource to the queues of each basic resource which the first video capability will require in order to perform the first sub-job.
