  • Patent number: 6487189
    Abstract: A system is presented for transmitting document references or tokens to users of integrated wireless and wire-based communication services. The system includes workstations, files servers, printers and other devices coupled to a wire-based network. Mobile computing devices are coupled to the wire-based network through either IR (infrared) or RF (radio) transceiver gateways. Each mobile computing device appears to hold a uses personal collection of documents: the device is programmed to receive, transmit, and store document tokens. A document services request available to users of the mobile computing devices is an email-to-token service. Using this service, document tokens are emailed to recipients with an email account. The transmission protocol for performing the email-to-token service includes the step of transmitting a token-to-email service request from the mobile computing device over the wireless communication service to a token-enabled server located on the wire-based network.

  • Patent number: 6487659
    Abstract: In carrying out various authentication with use of a proof support information, it is intended to impose a limitation on utilization and make high-speed processing possible. Proof data generation control information is provided to a proof data generation device from a proof data generation control information generating device or from a proof data verification device. At the time of authentication, authentication data is provided from the proof data verification device to the proof data generation device, in which a proof data generation unit generates proof data on the basis of the authentication data, user unique identifying information, proof data generation control information, and proof support information (access ticket). However, in the event utilization does not meet conditions included in the proof data generation control information, generation of the proof data is rejected. The proof data is sent to the proof data verification device and is verified thereby.

  • Publication number: 20020174150
    Abstract: Dynamic language translation is provided for a content portion through the use of a dynamic translation service which stores language information associated with specific client and user information. The dynamic translation service determines a language based on the client and user information. A skeleton of the content portion is then determined containing content elements of the content portion. The skeleton content elements are translated into the determined language based on the client and user information using stored translation tables of each skeleton content element or using dynamic natural language translation of each skeleton content element. The translated skeleton content elements are then merged into the content portion.

  • Publication number: 20020173146
    Abstract: Efficient methods are disclosed for fabricating metal plated spring structures in which the metal is plated onto the spring structure after release. A conductive release layer is deposited on a substrate and a spring metal layer is then formed thereon. A first mask is then used to form a spring metal finger, but etching is stopped before the release layer is entirely removed. A second mask is then deposited that defines a release window used to remove a portion of the release layer and release a free end of the spring metal finger. The second mask is also used to plate at least some portions of the free end of the finger and selected structures exposed through the second mask. Remaining portions of the release layer are utilized as electrodes during electroplating. The resulting spring structure includes plated metal on both upper and lower surfaces of the finger.

  • Publication number: 20020170667
    Abstract: A process for fabricating an endless flexible seamed belt, substantially equivalent in performance to a seamless belt, includes forming the belt by joining two ends of a substrate material. Each end of the substrate has mutually mating elements in interlocking relationship. The surfaces of the mutually mating elements have a gap therebetween into which bonding material is applied such that there is no substantial thickness differential between the seam and the portions of the belt adjacent the seam. The bonding material is then cured by any known means and post-cured to improve the stability of the bonding material and to achieve an effectively electrically invisible seam for an electrostatographic imaging system operating at high temperatures.

  • Publication number: 20020172395
    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: 6483606
    Abstract: A method of error diffusion selects colorants, from a plurality of colorants defining a color space, to obtain an actual color which represents a desired color for respective pixels. The actual colors are output by an output apparatus. The process first determines the desired color for a pixel. Next, undercolor removal is performed for the desired color, thereby dividing the desired color into first and second components. A scalar error diffusion is then performed for the first component of the desired color, resulting in a first component of the actual color. A vector error diffusion is performed for the second component of the desired color. The vector error diffusion calculates an error as a negative of a distance in the color space between a closest available colorant in a subset of the plurality of colorants and the desired color. The error is added to the desired color to obtain a second component of the actual color.
