A method of assembling a metallic-graphite structure includes forming a wetted graphite subassembly by arranging one or more layers of graphite fiber material including a plurality of graphite fibers and applying a layer of metallization material to ends of the plurality of graphite fibers. In response to a request to write a first file to a tape, whether a second file including data identical to the first file already exists on the tape is detected. A second web comprising sheet members continuously arranged in the transverse direction thereof is continuously fed onto the first web wherein each of the sheet members is destined to be attached to the inner surface of the associated chassis in the crotch region thereof and thereby to form a body waste receiving pocket. A high pass filter is connected between ground and the base of the transistor. In this case, a control unit outputs the device identification information after the group identification information is received and then a standby time has elapsed. The system includes a monitoring and detection subsystem, a communication subsystem, and a flushing subsystem.
