  • Patent number: 7912386
    Abstract: Systems and methods are provided for using a sensor to determine a charge-to-mass ratio, and a concentration, of a mixture including a first component and a second component. A base resonance frequency of the sensor in an unloaded state is measured. A surface of a vibrating element of the sensor is loaded with the mixture. A first resonance frequency, of the loaded sensor is measured and a mass of the mixture is calculated. A first component is attracted to, and a second component is removed from, the vibrating element of the sensor. A second resonance frequency, and a first charge, of the sensor are measured. The first component is removed and a second charge is measured. A mass and charge of the first component are calculated. Charge to mass ratio, and the concentration, of the first component are then derived from the calculated values.

  • Patent number: 7912416
    Abstract: A printing system comprises a paper path architecture for parallel printing using multiple marking engines. The media path configuration enables all the media feed trays to be located in one place, relative to the marking engines. A cross-over module is located between marking engines. The cross-over module can interleave media sheets that are being transported away from a first marking engine with the sheets being transported to the second marking engine. The cross-over module also includes a straight through path that enables media sheets to be transported directly to a finishing device without going through either marking engine. The marking engines include internal duplex loops such that media can be supplied to each engine in alternate groups. A merge module selectively merges the media which can then be further processed in a finishing transition module prior to communication to a finishing device.

  • Patent number: 7913160
    Abstract: A document can contain multiple print layers. Different layers can be combined to produce different document versions. In this manner, a document can have an English version and a Spanish version that share graphics layers but have different text layers. A document's different layers can be difficult to track and the difficulty can lead to errors in document proofing and production. A discrimination module can automatically classify layers as common, graphics, and text containing. The text containing layers can be further grouped by native language. The layer groups can then be automatically combined to produce the desired document version specifications that can be rendered as document versions.

  • Patent number: 7912387
    Abstract: A kit used in TC measurement in the field includes a sandwich of 3 screens used for filtration of carrier beads from toner particles within a container. An upper 400 mesh screen has die-cut holes around its edges to allow removal of any beads trapped between the upper screen and a middle 500 mesh screen. A bottom screen of coarse 20 mesh material is used for strength to support the other screens. When a vacuum source connected to a bottom portion of the container is turned ON, the carrier beads approach the screens in the center of the container. The recirculating airflow carries the carrier beads away from the upper screen at the edges. Thus, with the upper screen being die-cut with openings around its edges, these openings allow the trapped beads to return to the inner chamber of the container for removal during cleaning.

  • Patent number: 7911479
    Abstract: A mapping technique is disclosed that maps color image data of an image displayed on a first image display device to output color image data for display on a second image display device. This mapping technique maps the color gamut of the first image display device to the color gamut of the second image display device while controlling one or more characteristics of the color image data, and generates one or more lookup tables that correspond to the gamut mapping, for example. The color image data is then mapped to the output color image data based on the lookup tables.
