  • Patent number: 8199035
    Abstract: A data communication device or system includes a preamble unit and a data interface. The preamble unit generates or detects a first preamble having a first length for a first data line, and generates or detects a second preamble having a second length for a second data line. The first length is different from the second length, and data on the first and second data lines form parallel data. The data interface communicates a first data with the first preamble via the first data line and communicates a second data with the second preamble via the second data line. The respective length and/or respective pattern of each preamble are adjustable and/or programmable.

  • Publication number: 20080094788
    Abstract: A memory card includes a piezoelectric material and a display unit. The piezoelectric material generates a voltage from external pressure applied thereon, and the display unit displays information using the generated voltage. Thus, information is displayed on the memory card at the discretion of the user pressing the piezoelectric material without using any additional equipment. Also, few components are added to the memory card for such a display function such that the small form of the memory card is retained.
