  • Patent number: 6584903
    Abstract: A print controller which produces a device specific raster for its printer and also produces a rasterized output in portable and more editable form for export and re-use as an input by other printers which may have different parameters. If the input is in a device independent color space, the rasterized export also will be in a version in a device independent color space, typically CIELAB. If the input is in a printable device dependent color space such as CYMK, the output will be an more editable rasterized version in the same color space, with any printing hints that were in the original will be included in the output. In any case, an override can be provided to change the default selection to any other user-identified version. An example of a device independent color space is CIELAB, of a device dependent version applicable for a number of printers with similar parameters is SWOP CMYK, and of a device dependent version is a printer specific CMYK.

  • Patent number: 6587254
    Abstract: An image display medium that can maintain stable display characteristics without dew condensing on a display substrate surface or on particles in almost all environments in which the image display medium is presumed to be used, even if there are changes in the environment external to the image display medium. In a closed gap formed between a display substrate having an electrode and a back substrate disposed opposite to the display substrate and having an electrode, plural kinds of particle groups differing in color and charge characteristics and movable between the substrates by an electric field are sealed. The gap is given a proper amount of water vapor so that dew does not condense within a predetermined temperature range. Thus, favorable and stable display characteristics can be obtained.

  • Patent number: 6587227
    Abstract: An input scanner for scanning three-dimensional objects, such as books, on a platen. An elongated raster scanner produces a digital representation of a line image in an object plane that is a fixed distance in front of the raster scanner's input optics. When scanning the three-dimensional object the raster scanner travels along a track guide that is contoured in the Z-direction. That contour is designed to mimic the contour of the three-dimensional object being scanned. When traveling along the track guide the distance between the three-dimensional object and the object plane remains substantially constant.

  • Patent number: 6585360
    Abstract: An ink tank, having an ink reservoir separated from an ink supply chamber which contains at least one foam element, is provided with one or more pipes in the partition which separates the ink reservoir from the ink supply chamber. The pipes transport ink from the ink reservoir to a portion of the ink supply chamber which does not contain the at least one foam element. This results in both minimizing leakage from the ink tank when the ink tank's protective seal is removed prior to inserting the ink tank into a print engine, and in more predictable ink supply pressure and accuracy from the ink tank to a print device.

  • Publication number: 20030116694
    Abstract: A system to monitor light emitting diodes (LEDs) in a printbar is described. The system integrates photodetectors into a printer or into the printbar itself such that as the printbar ages, the photodetectors can detect the decrease in intensity of the LEDs in the printbar and recalibrate driver circuits providing power to each LED. The recalibrated power output of each driver circuit compensates for nonuniformities in the LEDS that result from uneven aging of the LEDs.
