  • Publication number: 20160252989
    Abstract: A touch panel and a method for fabricating the same are disclosed. The method for fabricating the touch panel forms a pattern of a protruding structure on a base substrate by using a negative photoresist material, and the pattern of the protruding structure formed thereon is a pattern having a cross section which gradually increases from the base substrate to the outside surface and is similar to an inverted trapezoidal. Thereafter patterns of a touch electrode and dummy electrode insulated from each other are formed by using the pattern of the formed protruding structure as a mask. As the pattern of the touch electrode and the dummy electrode are disconnected through level difference of the protruding structure, the patterns of the touch electrode and the dummy electrode overlay the whole base substrate from the top view, allowing the whole surface of the touch panel to have the same optical property.

  • Publication number: 20160050161
    Abstract: In an example, a server architecture is described for a dynamic cascaded node chain providing a resource cluster. The cascaded node chain may include one or more resource instances provisioned as a head node, zero or more middle nodes, and a tail node. Each node may include a discrete number of available resource entries in a flow table. As traffic enters the head node, each node attempts to match the traffic to an entry in its flow table. If no match is found, the packet is downlinked to the next node in the chain. If the packet reaches the tail node without a match, it is punted to the controller. The controller may then provision a matching entry if an entry is available. If not, the controller may spawn a new resource instance. When the full capacity of the cluster is reached, non-matching entries may be dropped.
