A system, method, and computer program product for generating flow-control signals for a processing pipeline is disclosed. In one embodiment of the present invention, the method comprises providing a server platform and providing a datastore on the server platform for maintaining full resolution copies of the files shared between a plurality of sharing clients. The switch is responsive to linear accelerations, but is mounted in the probe so as to respond also to the rotation. During a service brake operation, the piston 26 alone is moved by a hydraulic pressure under a small piston thrust. The interfacial region contains an ion conducting electronically-insulating material along with components of the electrochromic andor the counter electrode layer.
