  • Patent number: 10014641
    Abstract: A crimping apparatus comprising a press module connected with a pressing mold, a translation module, and a pressure control module is disclosed. The press module generates an action force on the pressing mold through a fluid. The translation module is coupled to the press module for driving the press module to move toward a flexible printed circuit having two isolated circuit layers such that one circuit layer is pressed to crimp to the other circuit layer, wherein the pressure control module adjusts the pressure within the press module to maintain a constant force on the pressing mold whereby the pressing mold can generate a constant stress acting on the flexible printed circuit during the crimping process. In addition, the crimping apparatus can be adapted in a roll-to-roll process for crimping two isolated circuit layers of each flexible printed circuit unit arranged on the roll.

  • Publication number: 20180146075
    Abstract: A network communication protocol translation system and method are provided. The SDN controller receives a first packet from the SDN switch. The first packet records the name of the source protocol of the source apparatus and the name of the destination protocol of the destination apparatus. The source protocol and the destination protocol are different. The SDN controller forwards the first packet to the cross proxy. The cross proxy translates the first packet that conforms to the source protocol into the second packet that conforms to the destination protocol and transmits the second packet to the destination apparatus. The cross proxy receives the third packet from the destination apparatus, translates the third packet that conforms to the destination protocol into the fourth packet that conforms to the source protocol, and transmits the fourth packet to the source apparatus.
