  • Publication number: 20050262955
    Abstract: A deflection compensation system for automobile drivetrain components is provided, wherein a shaft is able to continue in driving relationship to another shaft or coupler in driven relationship when their respective axes of rotation are misaligned. At least one of the shaft and the coupler is preferably supported independently of the other and provided with crown involute splines, whereby one of the shaft and coupler when out of relative alignment, continues to drive the other without the necessity of adding additional moving parts to the drivetrain component.

  • Publication number: 20050165500
    Abstract: Systems and method of modeling computationally complex problems are provided. A first set of physical entities is mapped to a first set of entities in a massively multiplayer online game (MMOG). A second set of physical entities is mapped to a second set of entities in the massively multiplayer online game. Each player in the massively multiplayer online game manipulates members of the second set of entities to interact with the first set of entities in accordance with a quest defined in the massively multiplayer online game. A subset of members of the second set of physical entities corresponding to members of the second set of entities in the massively multiplayer online game having an outcome exceeding a preselected outcome is selected.

  • Publication number: 20050013976
    Abstract: A method of making a liquid-crystal sheet material, useful for displays, having polymer-dispersed cholesteric liquid crystals, comprising the steps of providing a emulsion comprising dispersed cholesteric liquid crystal domain and a solution comprising gelatin and a hardening agent, coating said emulsion onto a substrate; and drying said emulsion to form polymer-dispersed liquid-crystal domains dispersed in a continuous matrix comprising hardened gelatin. The invention is also directed to a display having an imaging layer comprising domains of polymer-dispersed cholesteric liquid-crystal material dispersed in a continuous matrix comprising hardened gelatin, said imaging layer disposed between first and second conductors. The invention is advantageous in reducing sensitivity to temperature and/or high humidity, especially in thin displays or displays that are open to the environment.
