Abstract: Several variations in full-color additive gyricons are shown. Each gyricon shown has been designed for ease of construction by eliminating the need for precise placement of rotating elements, alignment between the gyricon layers, if any, and alignment between the gyricon sheet and the addressing device.

Abstract: An electronic display device includes a two-dimensional array of point charge sources, which are aligned with a plurality of apertures defined in a substrate. Associated with each aperture is a set of electrodes, including a focusing electrode, which in effect funnels the ions from the charge source into a narrow stream, and a plurality of displacing electrodes, through which the ion stream can be caused to scan over a small two-dimensional area on a phosphor. Modulating the bias on the focusing electrode can be used to control the ion stream passing through an individual aperture according to image data. The combined action of a two-dimensional array of charge sources and associated control devices can create a single composite image on the phosphor.

Abstract: A process for the preparation of an unsaturated polyester which comprises (i) reacting an organic diol with a cyclic akylene carbonate in the presence of a first catalyst to thereby form a polyalkoxy diol, and (ii) optionally adding thereto a further amount of cyclic alkylene carbonate in the presence of a second catalyst, and (iii) subsequently polycondensing the resulting mixture with a dicarboxylic acid.

Abstract: An image processing apparatus is disclosed which comprises:means for inputting image data,color distribution recognition means for recognizing a color distribution in a color space and position information in an image space of the image data input through the input means, andmeans for determining one or more color reproduction parameters of the image data based on the color distribution and position information recognized by the color distribution recognition means and a color reproduction range of an output device.

Abstract: The electronic document reading and skimming system presents a document using a variable emphasis attribute. The emphasis varies based on a degree with which each term in the document represents the overall content of the document or the user's interest with respect to that document. The system and method of this invention calculates a score for each term that reflects the degree to which each term represents the overall content of the document, maps the scores to a variable emphasis attribute of a presentation system and then presents the document in accordance with the mapped scores.

Abstract: A photoreceptor having a substrate, including: (a) a charge generating layer; (b) a first charge transport layer having a first charge carrier mobility value; and (c) a second charge transport layer having a second charge carrier mobility value, wherein the first charge transport layer is closer to the charge generating layer than the second charge transport layer and the second charge transport layer is contiguous to the first charge transport layer, wherein the second charge carrier mobility value is higher than the first charge carrier mobility value.

Abstract: A method is described to combine together at least two continuous tone digital images into a combined digital image. When viewed in the standard manner, the combined image appears to be the first of the two images. The second image cannot be seen. When the bits within each pixel of the combined image are reversed, i.e. the least significant bit (LAB) is exchanged with the most significant bit (MB), and the resultant image is viewed, then the second image is seen. In this way, one image can be hidden inside the noise bits of another image. The method is applied to color images by treating each color separation independently. The encoding of one image into the other, while maintaining good image quality is accomplished using two simultaneous error diffusion calculations to determine the single output value for each pixel.

Abstract: An ink recording method is disclosed, which comprises printing a recording paper with an aqueous ink and immediately thereafter applying pressure onto the recording paper, whereby sharp images can be printed at high speed even on a plain paper.

Abstract: A method and apparatus are disclosed which analyze the video surrounding a pixel being classified and augment a calculated absolute value of the sum of the laplacians Sij just enough to enable reliable document type detection based on the other microclassifiers. The augmentation in effect removes Sij's contribution to the document-type decision to an extent which varies with the video. Where the Sij calculation is expected to be robust, augmentation is small and Sij remains a factor. Where the Sij calculation is weak, augmentation is larger and the other microclassifiers used for halftone detection dominate the classification decision.

Abstract: The invention provides a data packing device that packs selected bits of input data into an output data. The data packing device includes a data positioner, an output latch, and output selector and a controller. The data positioner positions the bits of the input data relative to bit positions of the output latch so that the selected bits from the input data may be packed. The output latch includes a first portion and a second portion which are packed alternately in a ping-pong manner. The controller is implemented using state machines where one state machine is allocated for packing a specific number of bits selected from the input data into the output data. Thus, the controller includes a number of state machines where each state machine corresponds to one selected number of bits of the input data that may be selected to be packed. For input data in bytes, the controller includes eight state machines.

Abstract: A data transfer apparatus and method uses recovery-type congestion control and avoidance-type congestion control. A bandwidth determination unit determines a requested bandwidth for a congestion avoidance-type data transfer in accordance with control information communicated between applications prior to the congestion avoidance-type data transfer. A bandwidth estimation unit estimates a bandwidth having been used by a congestion recovery-type data transfer in accordance with the control information communicated between applications prior to the congestion recovery-type data transfer. A management information memory stores information data of all the congestion avoidance-type data transfers and congestion recovery-type data transfers that use the bandwidth at a particular moment (i.e., simultaneously).

Abstract: An improved apparatus and method for reducing media wrinkling, especially in envelopes, caused by transport through a fusing nip are provided. To compensate for stress build up in the media as it travels through the fusing nip, the media is bent or "pre-stressed" in a direction opposite to the nip stress prior to the media entering the fusing nip. A media support surface is positioned upstream from the fusing nip to pre-stress the media by providing pre-nip bending to the media. The media is bent in a direction opposite to the curvature of the harder nip roller prior to the media entering the fusing nip. This pre-nip bending of the media substantially offsets the nip-stress imparted on the media by the fusing nip.

Abstract: A system for submitting upgrades to software which operates a digital printer. The software enters the printer through a standard printer port. When an upgrade is sent, the status pins are reassigned new functions relating to the progress of the software upgrade, instead of using the status pins of the printer port in a standard fashion for submitting print data. In upgrade mode, the levels of the status pins are recognized as a multi-bit word, relating to a specific condition of the upgrade.
