  • Patent number: 7744416
    Abstract: A high speed electrical connector assembly (1) comprises a female connector (2) and a male connector (3) assembled together to be electrical connection to a printed circuit board (9). A plurality of differential pairs of signal contact (51) and a plurality pairs of ground contact (53) with the pairs of signal contacts (51) arranged therebetween are secured in the connector assembly (1). Each of the differential pairs of signal contact (51) has a first contact engaging portion (511) which is accessible from the female connector (2), and includes a second contact engaging portion (513), extending away from the first engaging portion (511) and accessible from the male connector (3). A shielding bus (10) is electrically interconnecting to at least one of the ground contact (53), and includes a shroud portion substantially enclosing the median portion of the pair of signal contacts (51).

  • Publication number: 20060135202
    Abstract: The present invention provides a method of transmitting facsimile over a mobile communication device, capable of fast and effectively sending facsimile by wireless facsimile services, comprising the steps of: defining a data structure to set up a transmission format; editing a facsimile content to conform to the transmission format; verifying the GPRS authentication to start the communication service for data transmission; waiting to receive the response for successful transmission after the data have been transmitted, so as to confirm the completion of the operations, and finally disconnecting the GPRS service.
