  • Patent number: 9977544
    Abstract: The present disclosure relates to touch technology, and more particularly to a touch device and a method of fabricating the same. The disclosure provides a touch device comprising a protective cover having a sensing area and a peripheral area surrounding the sensing area; a first decoration layer disposed on the peripheral area; a sensing electrode layer comprising a sensing portion disposed on the sensing area and an extension portion extending from the sensing area to the first decoration layer; a second decoration layer disposed on the first decoration layer; a signal line formed on the second decoration layer and connected to the extension portion of the sensing electrode layer. By the design of the foregoing first and second decoration layers, the broken state or interruption of the sensing electrode layer can be prevented. In addition, the disclosure also provides the fabricating method for the foregoing touch device.

  • Patent number: 7127056
    Abstract: Dynamic adaptation of connection-oriented networks is introduced wherein, once congestion is encountered, dynamic adaptation steps may be performed. Four adaptation steps are proposed for reacting to various network congestion scenarios. It is further recommended that the steps are performed in a particular order such that the higher severity and longer sustentation of the network congestion the more strict step is performed to alleviate the network congestion. At a switch in the connection-oriented network, utilization of a trunk carried on a link connected to the switch is monitored and, if said utilization of said trunk exceeds a first threshold, a first degree of adaptation is initialized wherein use of the trunk by further connections is prevented. Subsequent degrees of adaptation are triggered when high utilization continues and surpasses higher thresholds. The subsequent degrees of adaptation involve rerouting connections that make use of the trunk.
