  • Publication number: 20130133835
    Abstract: A delamination apparatus includes a stage, a first roll unit, a gripper, and a second roll unit. The stage includes a peripheral area and a substrate area. An edge of a donor film is attached at the peripheral area. An acceptor substrate, laminated at on the donor film, is disposed at the substrate area. The first roll unit is disposed on the donor film, moves in a lengthwise direction of the acceptor substrate. The gripper is disposed on the donor film, and is configured to separate the edge of the donor film from the stage so as to cause the donor film to contact the first roll unit. The second roll unit is disposed on the stage, contacts the donor film which contacts the first roll unit, and delaminates the donor film from the acceptor substrate by moving in the lengthwise direction with the first roll unit.

  • Publication number: 20050283532
    Abstract: A system and method for multi-modal context-sensitive applications in a home network are provided. The system includes an input processing agent classifying inputs from a predetermined input device based on at least one criterion selected from the group consisting of an input block, an input type, a priority, and ranking and then outputting the classified inputs; an input collaboration agent performing real-time analysis on each of the inputs fed by the input processing agent to obtain a pre-defined output action for an input type corresponding to each input based on a user's context and performing a probabilistic inference on the inputs fed by the input processing agent to obtain a possible output action based on the user's context; and an agent server obtaining an output resource, which is available in the home network and corresponds to the user's context, based on the output action obtained by the input collaboration agent.
