Disclosed is a FAX signal transmission system, in which the transmission side and the reception side are inter-coupled by a bearer. The the system for repairing a brassiere includes at least one connecting ring assembly for coupling a shoulder strap to a main portion of a brassiere, and at least one length adjusting assembly positionable on the shoulder strap and couplable to an end of the strap. The method includes composing the at least two digital video sequences into the video stream in correspondence with a result of the multiplexing and subsequently including a sequence of dummy timing pictures into the video stream. The methods may be practiced with any encoder, including absolute and incremental encoders. A disguised decoy data sequence number is generated and inserted into the MAC header. A pressure source of the present includes a pump coupled to a reservoir through unidirectional valves.
