  • Tag control for runtime glossmarks
    Patent number: 7193751
    Abstract: The present invention relates to the manipulation of differential gloss as may be inherent in halftoned images by utilization of tags. By selectively applying halftones with anisotropic structure characteristics, which are significantly different in orientation while remaining identical in density, as directed by tag settings, a gloss image may be superimposed within an image without the need for special toners or paper. Conventional copier systems will not typically be able to copy such a superimposed gloss image.

  • Scan non-linearity correction using frequency modulation and synchronization with a master clock
    Patent number: 7193643
    Abstract: An electronic circuit is utilized to correct scan non-linearity of a raster output scanner. The circuit modulates a clock frequency to match a scan linearity error profile. Because it is a separate circuit, the exiting closed-loop clock generator does not need to be modified. The correction circuit synchronizes itself with the clock signal using a counter/subtractor phase detector, which ensures that the phase and frequency of the internal clock matches the phase and frequency of the master.

  • Systems and methods for indexing each level of the inner structure of a string over a language having a vocabulary and a grammar
    Patent number: 7194450
    Abstract: Systems and methods for indexing and searching the inner structure of a string over a language having a vocabulary and a grammar using bit vectors. The index preserves the inner gramatical structure of the string while allowing for a fast search. A single search provides immediate access to every level of a document, without having to re-search a single string to determine which sub-parts of that string match the search string. When a string is indexed, the index maintains a compositional representation and the grammatical relationship between the elements of the vocabulary according to the language. The string is then indexed on different levels by disregarding some of the grammatical relationships of component levels.

  • Two particle electophoretic systems, electronic displays including two particle electophoretic systems, and methods for producing the two particle electophoretic systems
    Patent number: 7193769
    Abstract: An electrophoretic display includes a transparent polymeric film including at least one cavity including a first particle species and a second particle species. Application of an electrical field causes the first particle species and the second particle species to separate from one another, and align on opposite sides of the cavity. Subsequent electric field applications cause migration of the first and second particle species, affecting a color state of the display. The electrophoretic display may be fabricated from multiple display cells arranged on a substrate.

  • Systems and methods for constrained anisotropic diffusion routing within an ad hoc network
    Patent number: 7194463
    Abstract: This invention describes methods and systems for tasking nodes in a distributed ad hoc network. A node is selected to participate in a data gathering or a routing task based on its potential contribution to information gain and the cost associated with performing the task such as communication bandwidth usage. This invention describes methods and systems for implementing various selection strategies at each node, using local knowledge about the network. For resource-limited sensor networks, the information-driven data gathering and routing strategies significantly improve the scalability and quality of sensing systems, while minimizing resource cost.

  • Droplet ejecting head and droplet ejecting apparatus
    Patent number: 7192118
    Abstract: When ejectors (nozzles) are viewed in order in a sub-scanning direction, the ejectors are arranged so that positions of the ejectors in a main scanning direction alternate in an offsetting manner. When formed dots are viewed along the sub-scanning direction, sizes of the dots are changed at random. Accordingly, density unevenness is decreased, the ejectors can be arranged in high density, and an image can be recorded at high speed. That is, the invention provides a droplet ejecting head in which density unevenness which tends to be generated in a head having a matrix-like nozzle arrangement can be decreased without decreasing recording speed and thus high-speed recording is made compatible with high-quality recording. The invention also provides a droplet ejecting apparatus which is provided with the droplet ejecting head.
