  • Patent number: 8990676
    Abstract: A method for processing application forms comprising extracting content from filled first forms of consumers, each of the first forms comprising one or more fields, arranging the extracted content of one or more fields of the plurality of fields of the plurality of filled first forms in a first matrix; encoding the content of each of the rows of the first matrix to define a second matrix; and disposing the encoded content of the second matrix in multiple empty second forms such that content of one column is disposed on only one of the empty second forms, each of the second forms includes the same type and number of fields as that of one of the filled first forms, further wherein the number of the filled second forms is based on the number of the one or more fields in the filled first forms.

  • Patent number: 8864294
    Abstract: The present disclosure provides systems and methods for supplying solid-ink pellets from a container to an image-forming device. The system includes a delivery tube within the container, with one or more openings to receive solid-ink pellets from the container. An agitating structure coupled to the delivery tube disturbs the solid ink pellets. The movement of the delivery tube moves the agitating structure, resulting in disturbing the solid-ink pellets and maintaining flowability of the pellets to the image-forming device.

  • Patent number: 8783839
    Abstract: An apparatus and method disclosed for delivering solid-ink pellets in an image-forming device comprises a hopper that houses solid-ink pellets. The hopper defines a vent and is provided with a mechanism to regulate the passage of the solid-ink pellets through the vent. A restrainer member configured to receive the solid-ink pellets defines a restrainer surface and a spreading arrangement to evenly spread the solid-ink pellets on its surface. Positioned below the vent, the restrainer retains the solid-ink pellets and is configured to transmit heat to solid-ink pellets causing them to melt evenly.

  • Patent number: 8068257
    Abstract: A method of printing comprising setting a pixel black value of K for an ink limit and identifying each of black dots of a first subset of black dots having pixel black value K greater than the ink limit, and pixel color value of cyan, magenta, and yellow equal to zero. The method further comprises rendering only K for a pixel value for the first subset of black dots and replacing each of black dots of a second subset of black dots of a halftoned bit map for a predetermined area with a process black dot.

  • Patent number: 8049935
    Abstract: An optical scanning device is provided which comprises a laser array which emits laser beams including a number of beams (1, 2, . . . , n) writing a swath of rasters having a laser scanning section which, when an interlaced scanning period i, is set to a natural number between beams which are adjacent in a sub-scanning direction, scans the laser beams emitted from the laser array with the interlaced scanning period i. The laser scanning section can scan the laser beams such that the beam number n and the interlaced scanning period i are relatively prime natural numbers, and n>i. In a first scan, data for raster lines (1, 2, . . . , n) can be selectively associated with a respective first exposure. At a second scan, data for raster lines (i+1, i+2, . . . , n) can be selectively associated with a respective second exposure and data for raster lines (n+1, n+2, . . . , n+i) can be selectively associated with a respective first exposure. The first respective exposure for raster lines (i+1, i+2, . . .

  • Publication number: 20110235291
    Abstract: This is a PCBA that can be used in any system where one component or package is connected to another component or package. This invention provides a very short connector or signal path that avoids the necessity of a signal trace termination in the PCB. The PCB has on its upper surface a first component or package and on its lower surface a second component or package in vertical physical and signal alignment with the first component or package. The first component or package has a BGA on its bottom surface and the second component has a BGA on its top surface, both of these BGAs are in electrical contact with each other. Because of the short signal trace provided, the PCB provides signal transitions as fast as 200 pS.

  • Patent number: 7756428
    Abstract: A system for handling media sheets is provided which comprises a plurality of hardware components including a first image marking engine operative to mark media sheets, and a second image marking engine operative to mark media sheets. In addition, the plurality of hardware components can include a first object delivery path operative to transport media sheets presented by the first image marking engine to a first destination, and a second object delivery path operative to transport media sheets presented by the second image marking engine to a second destination. The first and second destinations may be a single destination, separate destinations, or interchangeable destinations. One of the first and second delivery paths can be redundant.

  • Patent number: 7349118
    Abstract: A process that provides a status report following a request for the destruction of data files a user wishes to completely erase from a storage medium, such as a hard drive or removable disk. A system administrator can select a quantity of and pattern to be used in overwrites of the data file so that no one can recover the data from the storage medium. In embodiments, a graphical user interface (GUI) can be provided to allow user triggering of and parameter setting for the process. The GUI can be implemented at a device in which the storage medium is a component or can be implemented in a device driver GUI on a personal computer in communication with the device.

  • Patent number: 6641053
    Abstract: An image processing apparatus for encoding and decoding a document containing machine-readable code overlaid by human-readable content such that the code and the human-readable content are both discernable. In operation, a background image is generated, wherein the background image comprises coded glyphtone cells based on grayscale image data values, each of the halftone cells comprising one of at least two distinguishable patterns. The background image is overlaid with a second image such that some visible glyphtone cells may be decoded and the second image may be viewed. Finally, the decoded information enables comparison of aspects of the second image with a predetermined nominal reference.

  • Publication number: 20020002450
    Abstract: A method of filtering according to text genre the results of a topic search of a heterogeneous corpus of untagged, machine-readable texts. Because each text of the corpus has a topic and a text genre, the corpus includes multiple text genres and covers multiple topics. According to the method, a processor first searches the corpus for a first multiplicity of texts that have a first topic. Next, the processor identifies a first set of texts of the first multiplicity that are instances of a first text genre and identifies a second set of texts of the first multiplicity that are instances of a second text genre. Finally, the processor identifies to a computer user the first multiplicity of texts in an order based upon the first text genre and second text genre.
