Abstract: The present invention relates to techniques for supporting organizational, labeling and retrieval tasks on an electronic tabletop, wall or large display. In various embodiments of the invention, a dynamic visualization is used to show a current working set of documents. In an embodiment of the invention, the rest of the collection is represented in the background as small dots. In an embodiment of the invention, when a user moves objects into groups or creates a label, relevant objects in the background are automatically retrieved and moved into the foreground. In an embodiment of the invention, retrieved objects along with relevant objects in the current set are highlighted and decorated with arrows pointing to their relevant groups. In an embodiment of the invention, the movement is animated to provide user feedback when objects must travel long distances on a large display.

Abstract: A method of displaying an image in an electrophoretic display device includes charging each of the sets of differently colored particles to have a different charge through application of an electric field to the display fluid or the device, and then applying an electric field to selected ones of the multiplicity of reservoirs to effect movement of one or more of the differently colored sets of particles in the display fluid therein to display a desired color derived from among the sets of differently colored particles. The colors are shown by way of the particle set or sets moved to be closet to the viewing side conductive substrate of the device.

Abstract: An image processing apparatus that generates a reduced image from input image data, which includes: a reducing process dividing section that divides a reducing process applied to get the reduced image from input image data into a first and second reducing process; and an image reducing section that executes the reducing process in compliance with the first and second reducing process.
Abstract: Set forth is a method of forming an electrophoretic display device that includes locating a multiplicity of individual reservoirs containing a display fluid between conductive substrates, at least one of which is transparent, to form a device, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color, and charging each of the sets of particles to have a different charge via application of an electric field to the device. This field induced charging of the sets of differently colored particles enables low conductivity particles with superior electrophoretic mobility to be achieved.

Abstract: An image forming apparatus includes a developer that develops a latent image to form an image, a separation unit that separates image information of a job image by color upon writing a latent image of the job image, a comparison unit that compares the image information by color separated by the separation unit with a threshold value previously set with respect to an image concentration, and a driving condition determination unit that determines a driving condition of the developer using a result of comparison by the comparison unit.
Abstract: An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.

Abstract: The amount of lateral charge migration (LCM) on a photoreceptor is quantified by measuring the average potential of a latent image formed on the photoreceptor surface. The surface is first uniformly charged, then exposed a first time to an image. After a waiting period during which LCM may occur, the surface is exposed a second time to the image. After another waiting period, the average potential is measured. The amount of LCM may be quantified by varying the waiting periods.
