Abstract: Certain designs of paper feeding devices used in copiers and printers require that an edge of a stack of sheets be in close contact with a slanted surface. An apparatus engages an opposite edge of the stack to urge the stack against the slanted surface, so that the stack assumes a parallelogram shape. The apparatus includes a plate which is movable from a vertical, upright position to a slanted position. Means are provided to cause the plate to move to the slanted position in response to the closing of a paper tray of a printer or copier.

Abstract: The present invention relates to an intermediate transfer member having a polyimide resin film containing oxidized carbon black; and an image forming apparatus comprising an intermediate transfer member having a polyimide resin film containing oxidized carbon black.

Abstract: Systems and methods to enable real-time and near real-time storyboarding on the World Wide Web in addition to a graphical user interface for video parsing and browsing the of the storyboard. Specifically, storyboarding can be accomplished on the World Wide Web by parsing an input video into representative or key frames. These frames then can be posted to a web document, or the like, for subsequent viewing by a user. This allows a video to be distilled down to the essential frames thus eliminating storage and bandwidth problems as well as eliminating the need for a user to view the entirety of the video. Furthermore, the graphical user interface allows a user to visually interact with an input video signal to determine the key or representative frames, or to retrieve video segments associated with already determined key frames.

Abstract: A method for scanning a document includes: acquiring scanned image data from a first region of the document; determining an initial estimate of a document attribute using pixels in the first region; acquiring scanned image data from a second region of the document; processing pixels in the second region in accordance with the initial estimate; determining a second estimate of the document attribute using selected pixels in the second region; determining if the initial estimate is valid and if not, processing pixels within the image in accordance with the second estimate.

Abstract: In a photosensitive device wherein a photodiode is operated by placing an initial fat zero charge thereon before the integration of a light-induced signal, the actual dark level signal created by the fat zero charge is sampled with each readout from the photodiode, and then retransferred to the photodiode. After integration, the sampled dark level is subtracted from the total signal level on the photodiode. In this way both fixed-pattern and thermally-induced noise is obviated.

Abstract: Low acoustic solid wave attenuation structures are formed with an electroformed nickel mold, and are incorporated within acoustic ink emitters, between the focusing lens and surface of an ink layer. The structures have characteristics of low attenuation of acoustic waves to increase the efficiency of acoustic wave transmission within the acoustic ink emitter. Using the described structures, acoustic ink printers can accurately emit materials having high viscosity, including hot melt inks.

Abstract: In a computer system comprising a screen, a screen saver determines if a predetermined time period lapses and, saves a screen when the predetermined time period has elapsed. When the screen saver runs, messages can be left, and, when a user is identified, he can gain access to the left messages.

Abstract: In a printing system with multiple printheads, a spot of ink is created on a recording medium using up to N drops of ink fired from an ejector of one of the printheads. Each printhead has an array of ejectors. A single power supply drives the ejectors of the multiple printheads. Each of the printheads delivers a single color such as cyan, magenta, yellow, or black. A memory, which is coupled to the multiple printheads, records a printfile. Values in the printfile record channel values. Each channel value specifies how many drops of ink to deliver onto the recording medium over a spot cycle. The spot cycles of the multiple printheads, which consist of one to N actuation intervals, are desynchronized by operating the spot cycles out of phase with each other. The spot cycles of two printheads, for example, are desynchronized by beginning the spot cycle of one printhead a non-multiple of N drops prior to beginning the spot cycle of the other printhead.

Abstract: A method and apparatus for facilitating communication about a document between two users creates autonomous, animated computer characters, or avatars, which are then attached to the document under discussion. The avatar is created by one user, who need not be the author of the document, and is attached to the document to represent a point of view. The avatar represents the physical likeness of its creator. The avatar is animated, using an avatar scripting language, to perform specified behaviors including pointing, walking and changing facial expressions. The avatar includes audio files that are synchronized with movement of the avatar's mouth to provide an audio message.

Abstract: A method for developing an electrostatic image including contacting the image with at least one magnetic brush including (a) a rotating magnetic core of a preselected magnetic field strength, (b) an outer nonmagnetic shell, (c) An electrographic, two-component dry developer composition comprising charged toner particles and oppositely charged binder-free carrier particles which (a) include: an alloy of a soft magnetic material exhibiting a coercivity of at least 300 gauss when magnetically saturated, exhibit an induced magnetic moment of less than 20 EMU/gm of carrier when in an applied field of 1000 gauss and (b) a hard magnetic material exhibiting a coercivity of at least 300 gauss when magnetically saturated, exhibit an induced magnetic moment of at least 20 EMU/gm of carrier when in an applied field of 1000 gauss and which magnetic moment is sufficient to prevent the carrier from transferring to the electrostatic image, the toner and carrier particles in the developer having a triboelectric force of attra

Abstract: An apparatus and process for reducing accumulation of toner from the surface of an electrode member in a development unit of an electrostatographic printing or copying apparatus by providing an organometallic coating composition including an organometallic material on at least a portion of the electrode member.

Abstract: A system is provided for improving security during data transfer. A transmitter side transfer controller (12) divides data to be transferred into a plurality of pieces, removes a portion of data from each piece and encrypts the piece, and uploads each encrypted piece to different relay servers (22) on the Internet (20). The transmitter side transfer controller (12) also provides a receiver side transfer controller (12) information indicating which piece is uploaded to which relay server (22) using a secure communication protocol. The data of the fragment removed from each piece is transmitted to the receiver side transfer controller (12) separately from the encrypted pieces. The receiver side transfer controller (12) downloads the encrypted pieces each uploaded to the relay server (22), decodes the encrypted pieces, complements the decoded data with the data of the fragment to restore the state before the removal, and assembles the restored pieces to obtain the original data to be transferred.

Abstract: In a fuser, a cooling structure (5) is disposed so that a bend angle (&agr;) of a part bent during the time between an endless belt (3) coming in contact with a press cooling face (5a) of the cooling structure (5) and exiting from the press cooling face (5a) is placed in the range of 0° C.<&agr;≦7° C. A fixing belt has a minute hardness of 0.1 to 5 at least on the belt surface coming in contact with toner T and preferably has a gloss degree of 75 or more on the belt surface.
