  • Patent number: 8433293
    Abstract: The present invention relates to an apparatus and method of providing a content push service, a mobile terminal, and a method of operating a mobile terminal. According to an exemplary embodiment of the present invention, a user datagram protocol (UDP) port is set between the mobile terminal and a content push service providing server. In addition, the mobile terminal drives an application that receives the content push service through the set user datagram protocol (UDP) port, by the request of the content push service providing server. The mobile terminal receives the content push service from the content push service providing server through the driven application. Accordingly, it is not necessary to select a specific identifier for each of existing applications and recognize a specific identifier for each node of the mobile communication network.

  • Patent number: 8426252
    Abstract: In a semiconductor device package having a stress relief spacer, and a manufacturing method thereof, metal interconnect fingers extend from the body of a chip provide for chip interconnection. The metal fingers are isolated from the body of the chip by a stress-relief spacer. In one example, such isolation takes the form of an air gap. In another example, such isolation takes the form of an elastomer material. In either case, mismatch in coefficient of thermal expansion between the metal interconnect fingers and the body of the chip is avoided, alleviating the problems associated with cracking and delamination, and leading to improved device yield and device reliability.
