  • Patent number: 7345786
    Abstract: A method for color cast removal in a scanned image in L*a*b* space includes generating a first color cast correction curve for mapping L* to a first color correction, ?a*, (or ?b*) wherein the first correction curve provides a desired a* shift in midtone regions and is modulated as a function of L* such that black and white points are unaffected; for each pixel n in the scanned image, passing L*n through the first color cast correction curve for obtaining a value of ?a*n; and adding the value of ?a*n to the scanned image's original a*n component. To ensure that the color corrected a* remains within gamut, a second correction curve for applying a clipping factor to the mapped ?a* may be generated with the a*n passing through the second correction curve for obtaining a clipping factor Cn; and modifying the a*n value by Cn(?a*n).

  • Patent number: 7296223
    Abstract: A method for creating a structured document, wherein a structured document comprises a plurality of content elements wrapped in pairs of tags, includes parsing a document of a particular type containing content into a plurality of content elements; and for each content element, suggesting an optimal tag according to a tag suggestion procedure. The tag suggestion procedure includes providing sample data which has been converted into a structured sample document; deriving a set of tags from the structured sample document; evaluating the set of tags according to tag suggestion criteria to determine an optimal tag for the content element. The optimal tag may be a single tag or a pattern of tags which maximizes a similarity function with patterns found in the sample data.

  • Patent number: 7287024
    Abstract: An electronic board system includes an electronic board having a screen for displaying information of interest to a work group or community, an input device for receiving information from users in a group or community to be displayed on the electronic board, a memory for storing information received from the input device and a processor for selecting which information stored in the memory to display on the screen, where and how to display the selected information on the screen and displaying the selected information on the screen. The processor selects which information to display in accordance with a predetermined relationship based on a group-based recommendation criteria and user interest. A plurality of sensors disposed behind the screen detect user interest in information displayed on the screen near the sensor. User interest may also be determined by monitoring user requests for copies of information displayed on the screen.

  • Patent number: 7284324
    Abstract: An out-of-plane micro-structure which can be used for on-chip integration of high-Q inductors and transformers places the magnetic field direction parallel to the substrate plane without requiring high aspect ratio processing. The photolithographically patterned coil structure includes an elastic member having an intrinsic stress profile. The intrinsic stress profile biases a free portion away from the substrate forming a loop winding. An anchor portion remains fixed to the substrate. The free portion end becomes a second anchor portion which may be connected to the substrate via soldering or plating. A series of individual coil structures can be joined via their anchor portions to form inductors and transformers.

  • Patent number: 7274492
    Abstract: This invention is a method of producing a set of TRC's for a color printer's secondary halftone screens that is correlated with the printer's primary halftone screens. The method makes use of the printer/screen characteristic data that is normally gathered during screen calibration. However, instead of progressing from the data to a normal calibration for the secondary screens, the method goes backward through the data starting with the finished primary screen TRC's. The method insures that for every primary screen density, the closest possible secondary screen density is used when the same digital value is specified.

  • Patent number: 6956958
    Abstract: A method for enhancing color fidelity in multi-reproduction, includes scanning an image to be reproduced, wherein the image contains an invisible digital watermark including color information; decoding the color information contained in the watermark; comparing the decoded color information with the scanned image; generating a correction table from the differences between the decoded color information and the scanned image; and performing color correction on the scanned image using the correction table. This method confines the color error to one generation, even when copies go through multiple reproduction.

  • Patent number: 6782495
    Abstract: A method of diagnosing a printer problem includes correlating a wide range of printer data types with suggested solutions. Printer diagnostic data, which may include usage information and printer status information collected over a period of time, is parsed into individual components. The components are then input into a set of rules. Each rule compares each component with a corresponding reference value to generate a comparison result, correlates the comparison result with a set of actions including solutions, and if there is a correlation between the comparison result and a solution, providing the solution.

  • Patent number: 6662270
    Abstract: A system and method for enabling implementation-transparent caching of reusable objects in an application program using a language, which may be a page description language, with defined operators is described. A default operator from the language, which supports a set of default caching operations is selected. A set of additional caching operations for use in a specific caching implementation is created. The set of additional caching operations is associated with the defined operator. A key for selecting between the set of default caching operations and the set of additional caching operations is also defined. When the application program is executed, the application program automatically selects the set of default caching operations or the set of additional caching operations based on the value of the key.
