  • Methods for achieving improved color in microencapsulated electrophoretic devices
    Patent number: 7667684
    Abstract: A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink-jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.

  • VIDEO FRAME ENCODING AND DECODING
    Publication number: 20100040140
    Abstract: A video frame arithmetical context adaptive encoding and decoding scheme is presented which is based on the finding, that, for sake of a better definition of neighborhood between blocks of picture samples, i.e. the neighboring block which the syntax element to be coded or decoded relates to and the current block based on the attribute of which the assignment of a context model is conducted, and when the neighboring block lies beyond the borders or circumference of the current macroblock containing the current block, it is important to make the determination of the macroblock containing the neighboring block dependent upon as to whether the current macroblock pair region containing the current block is of a first or a second distribution type, i.e., frame or field coded.

  • Rolling plate assembly attachment for portable power cutting tools
    Patent number: 7661194
    Abstract: The present invention is an attachable rolling plate assembly which can be attached as a single unit to a portable cutting tool to facilitate the safe rolling movement of the portable cutting tool on the workpiece. The invention comprises a front wheel housing portion, a back wheel housing portion, and two or three metal rods which interconnect the two housings. The housings removably retain a pair of spaced apart wheels and means to retain a cutting tool on the housings so that the cutting tool can be rolled on the workpiece during operation of the tool while the cutting blade portion of the tool extends between a pair of adjacent interconnecting rod members. The front and rear wheel housing assembly receives the cutting blade in between its pins or axles, so that the entire width of the saw plate is supported by the wheels during cutting.
