A mobile self-contained self-powered station having a plurality of vessels delivers a pressurized fluid to a receiving tank without using mechanical compression, external electric power, or other external utilities. Each DSBT digitally filters individual carrier data bits from a digital multi-carrier data stream based on a programmable center frequency. When the request for moving the display area is suspended while the display area enters the restriction area, the bouncing speed determination unit determines the moving speed so that the display area is bounced in a direction away from the restriction area at a speed determined by the extent that the display area enters the restriction area. The inlet tubes each have a proximal end integral to either the manifold or one of the printheads, and a distal end connected to either the manifold or said printhead with a single fluid-tight connection. If the instance is already available from one of the libraries, the instance need not be created. The base plate and the spring plug are arranged for bayonet mount interaction wherein if the spring plug is placed against the second side of the base plate and then rotated for bayonet connection, part of the spring plug pushes the extension so as to force the pawl in the first position.
