A combo dynamic flop with scan flop circuit includes a flip-flop circuit, a scan control circuit, and an output buffer circuit. The valve device has an internal pressure membrane that regulates the inlet flow of the air to the tube pump. The method also comprises receiving the packet data from the transmitting station, wherein at least two of retransmitted packet data are transmitted from different antennas of the transmitting station, and one of retransmitted packet data is transmitted from the same antenna of the transmitting station. The high-pressure reservoir is coupled with the hydraulic pump.
