  • Publication number: 20100238202
    Abstract: An exemplary method for driving a display device is provided. At least one set of input signals is received. Finding the original signals being the same with the input signals in the signal transforming table is executed. The pixel driving signals is outputted. If at least one of the found second and third original signals is equal to zero, and the found first original signal is equal to neither zero nor maximal gray scale, at least one of the outputted second and third sub-pixel driving signals, and the outputted fourth sub-pixel driving signal are equal to zero. Then, at least one of the pixels of the pixel array is driven by the outputted pixel driving signals.

  • Patent number: 7779379
    Abstract: A routing tool allows a user to create a set of routing templates, each specifying the shape of a routing corridor and identifying the corridor's terminal edges. Each routing template also specifies a set of constraints on routing of an unspecified number of conductors that are to be routed between the corridor's terminal edges. To direct the tool to create a routing plan for a particular set of conductors in a particular routing space, the user selects one of the routing templates and modifies the routing template if necessary to adjust the specified shape of the corridor to match that of the particular routing space or to adjust its specified routing constraints if necessary to accommodate any particular routing constraints to be imposed on that set of conductors. The routing tool then processes the modified routing template to generate the routing plan for routing the set of conductors between the terminal edges of the specified corridor in a manner that satisfies the specified routing constraints.

  • Publication number: 20100189083
    Abstract: A wireless local network reconnecting system and method is provided. The method detects a connection-lost signal generated when a network node of the wireless local network group lost connection. A reconnecting coordinate is calculated according to the connection-lost signal and transmitted to the connection-lost network node through an external communication network. Afterwards, the method guides the connection-lost network node to move to the reconnecting coordinate and reconnect with the wireless local network group wirelessly. Since the external communication network is used to connect with the connection-lost network node, the connection-lost network node is able to reconnect with the wireless local network group through the proposed method.
