An input device contains a resistance-element series formed by series-connected resistance elements, low resistors opposing the resistance elements, an operating object which brings one of the low resistors into contact with one of the resistance elements and changes the contact area therebetween, an output point at the midpoint between resistance elements, and a controller. This polymer is useful in a variety of hot melt adhesive applications for consumer product articles subject to hostile use environments such as toys and other play things. A link identification component identifies one or more connecting links to one or more sets of peer machines, each set of machines connecting said source machine to said target machine, the link identifier further determining the bandwidth associated with each connecting link. A contour curve generator section 33 generates a contour curve candidate list corresponding to the list of the plurality of color projection axis candidates. The gas used is carbon dioxide and the lubricant is a hydrocarbon-based lubricant. The pumping unit is designed such that in operation the seal pressure vent system provides a fluidic path for the flow of high pressure water away from a lip seal assembly toward a near ambient pressure region.
