  • Patent number: 7891892
    Abstract: A printer and a process for correlating printed subject matter with subject matter that is meant to be printed by a printer with a printing mechanism or print engine such as a thermal printer including a print head, a platen, a media upon which labels are printed and a printer controller for imparting print data to the print head. An imager sends printed data as imaged to a read after print (RAP) controller for comparing the data received from the imager to data imparted to the print head or other printing mechanism. A tap, taps the data imparted from the print head and correlates it with the imaged data to determine the media speed, the image alignment, label analysis, weighing of blemishes, the gaps printed on a label, and other criteria.

  • Patent number: 7554898
    Abstract: An optical storage disc has portions for storing pre-recorded or mastered information and portions for storing user writable information, where the mastered portion and the writable portions have different storage capacities or areal data densities. During manufacture, a substrate is formed with a sequence of bumps to represent the mastered information and a series of grooves and lands, where information can later be written on the lands. A phase-change material is deposited over the substrate, the phase-change material changing both physical structure and optical constants when written to, e.g., by a laser.

  • Patent number: 7535027
    Abstract: An amorphous-silicon thin film transistor and a shift register shift having the amorphous-silicon TFT include a first conductive region, a second conductive region and a third conductive region. The first conductive region is formed on a first plane spaced apart from a substrate by a first distance. The second conductive region is formed on a second plane spaced apart from the substrate by a second distance. The second conductive region includes a body conductive region and two hand conductive regions elongated from both ends of the body conductive region to form an LI-shape. The third conductive region is formed on the second plane. The third conductive region includes an elongated portion. The elongated portion is disposed between the two hand conductive regions of the second conductive region. The amorphous-silicon TFT and the shift register having the amorphous TFT reduce a parasitic capacitance between the gate electrode and drain electrode.

  • Patent number: 7509116
    Abstract: A system for remotely tracking a mobile unit is presented. The system includes a computer connected to a data network, mobile units collecting data and transmitting the data to the computer, and a configuration database connected to the data network. The configuration database stores configuration parameters for the mobile units. The mobile units are programmed to contact the configuration database upon being powered on, obtain the configuration parameters, and transmit the collected data to the computer according to the configuration parameters. Since each configuration file could apply to multiple mobile units, the system provides an efficient way to control the data reporting patterns of many mobile units. The configuration database may be organized in layers of configuration files for improved flexibility. Files from different layers can be mixed and matched and then applied to a group of mobile units.
