  • Patent number: 7003585
    Abstract: A high speed, serial interface employs a simplified protocol which minimizes overhead enabling uncompressed image data to be sent serially over a long distance in real-time devices, such as a color printer. Because the error rate experienced in high speed serial and fiber optic links is very small and finite, the protocol removes the requirement to retransmit real time data. The protocol for initiator device-target device communications includes an idle message frame for indicating a device is ready for communication; a control word frame for sending a data request from the target device; a control word frame for indicating a transfer mode from the initiator device; and a data frame, wherein in response to a data request from the target device, the initiator device transmits a control word frame followed by the requested data.

  • Patent number: 7003237
    Abstract: Image formation condition is available, which hardly causes imperfections of the image quality. A full-color image formation system selects plural secondary transfer conditions in a secondary transfer unit within a specific range, forms test charts according to each of the secondary transfer conditions selected, and prints them out. A user checks by viewing the test charts printed on each recording sheet, and selects a page number of the sheet where the user evaluated an image quality as the best; and the image formation system sets the secondary transfer condition for the sheet as a standard secondary transfer condition thereafter.

  • Patent number: 7003737
    Abstract: A system and method for displaying, browsing and accessing content in real space and time. In one embodiment, a user may browse and access multiple types of electronic content in a three dimensional representation of real space and time, where each document has a time and space attribute. A user may also place electronic documents at different locations in real space and time. A user performs inquiries by moving a space indicator along a time line. A visual indicator representing a relevancy score may provide information regarding document proximity to a selected location in space and time. The relevance score may also offset uncertainties inherent in location tracking systems. A document window is provided to display documents located at a selected point in space and time. Visual indicators associated with the documents may represent the time and space location of each document. Documents in the document window may be sorted as desired by a user.

  • Patent number: 6999598
    Abstract: The systems and methods of this invention watermark an original data file using dimensional compression and expansion. The original data file extends along a given dimension and has portions that extend along that given dimension. The information is embedded into the data file by selectively dimensionally compressing or expanding a size of each of some or all of the portions along the given dimension, which can be space or time. The portions of the data file are selectively dimensionally expanded or compressed according to a given encoding scheme. This encoding scheme can use the kind of modification, the relationships between the type of modification between adjacent portions, or the duration or degree of compression or expansion to store a portion of the embedded information. The portions of the embedded information can be individual bits of binary or trinary information, or can be a portion of analog information.

  • Patent number: 6999218
    Abstract: A width in a main scanning direction of a laser beam is decreased in the outside of an effective scanning region in such a manner that the width along the main scanning direction of the laser beam is restricted by an aperture portion of an aperture member. As a result, so-called flare light is prevented from generating, and a uniformity of light quantity is improved. Namely, in a light scanning apparatus adopting an overfilled optical system, a light scanning apparatus which can prevent degradation of image quality due to flare light is obtained.

  • Patent number: 6999703
    Abstract: A device for ion charging airborne toner particles for the development of electrophotographic images is proposed. The ion toner-charging device subjects an airborne stream of toner particles to unipolar gas ions in the presence of an applied alternating electric field. The alternating electric field prevents the charged particles from depositing on the electrodes in the charging zone. The device uniformly charges irregular or spherical shaped toner particles to the Pauthenier charging limit. The device is an interface between various methods for supplying toner to the unit and developing an electrostatic image with ion charged toner.

  • Patent number: 6999066
    Abstract: What is presented is a system and method by which a visually impaired worker could easily and quickly navigate menu options on touch screen displays. An Audible Feedback ON/OFF Switch is provided which turns the audible feedback feature of the present invention on or off. The software monitoring which row/column areas of the touch screen's display grid have been touched by the user in response to a menu option selection is made switchable into one of two modes. A first mode is when the audible feedback feature is OFF or otherwise disabled. In this mode the software operates the touch screen's menu selections in the normal manner in which the machine is intended to perform. When a user selects an option, the option is immediately activated whether it be a machine activity or a jump to another level of menus. A second mode is when the audible feedback feature has been turned ON or otherwise activated.

  • Patent number: 6999711
    Abstract: An image forming apparatus includes a plurality of image forming units for forming an image on a printing medium such as a sheet of paper. A plurality of color types of toner are arranged on a transport path of the printing medium. Toner images corresponding to the color types of toner are color-by-color transferred onto the printing medium. Light emitted from a flash lamp melts and fixes the toner images. The fixing order of the toner images corresponding to the color types of toner is decided so that the toner images are fixed in ascending order of toner's absorptivity of the light emitted from the flash lamp or in descending order of toner's reflectivity of the light.

  • Patent number: 6998595
    Abstract: An architecture and manufacturing method for photosensitive chips, such as used in office equipment and digital cameras, involves creating grooves between chip areas in a wafer, and then placing a light-transmissive planar layer over the main surface of the wafer. The planar layer, which may be acrylic-based, creates a substantially planar surface over both the photosites in the chip areas and the grooves. The planar layer in turn supports one or more light-transmissive filtering layers. The arrangement avoids damage to the filtering layers when the wafer is diced along the grooves.

  • Patent number: 7000110
    Abstract: Without the need to store and manage a private unique value of a hash function for each token, and without the fear of organizational private information of a center being revealed, a hash function is provided to a token. A unique value input unit is supplied with a unique value d, which is a parameter required to generate a hash function X. A message input unit is supplied with a message M from which to find a hash value. A function generation unique value memory unit 3 holds a function generation unique value s, which is a parameter required to generate a value generation unique value. A value generation unique value calculation unit generates a value generation unique value u from the function generation unique value s and the unique value d. A hash value calculation unit generates a hash value X(M) by applying a hash function H to the value generation unique value u and the message M. A hash value output unit outputs the hash value X(M) generated by the hash value calculation unit.
