  • Publication number: 20140171139
    Abstract: The present application discloses methods and devices for intercommunication between mobile terminals based on digital networks. A first mobile terminal may connect to a uniquely identified server based on a first terminal identifier corresponding to the first mobile terminal. In addition, the first mobile terminal may connect to the server through a default connection setup embedded in the first terminal identifier. By acquiring terminal identifiers corresponding to interacting mobile terminals, the first mobile terminal may establish communication channels with the interacting mobile terminals. After adding the terminal identifiers of the interacting mobile terminals to the contact lists of the first mobile terminal, different regions of the first mobile terminal may be designated to the interacting mobile terminals so that the regions may display the status of communication and serve as interfaces to control receiving, playing, recording, and transmitting digital contents encoding voice messages.

  • Patent number: 8518742
    Abstract: A packaged semiconductor includes inner bond fingers, at least first and second semiconductor dies, and an interposer. The packaged semiconductor further includes wiring between the first and second semiconductor dies and the inner bond fingers, wiring between the interposer and the inner bond fingers, and wiring between the interposer and the first and second semiconductor dies. The wiring between the interposer and the first and second semiconductor dies thereby reduces the count of inner bond fingers needed for the wiring between the first and second semiconductor dies and the inner bond fingers. The interposer further provides indirect access to the inner bond fingers when the inner bond fingers are inaccessible by the first and second semiconductor dies.
