The no-rinse cleaner is virtually streak-free by virtue of the added boric acid or borate. Assembly is the unequal coaxial assembly and comprises of a cam {sun-element}, bearing and rollers {planet-element}. In another aspect, a prosthetic simulator comprises a prosthetic drive mechanism; a feedback control system that drives the prosthetic drive mechanism; and an iterative learning control system that determines an error from a previous iteration of motion of the drive mechanism and uses the error to determine a drive signal for a subsequent iteration of motion. Formed into the component of areal form is at least one stamped portion, the height of which is formed so as to correspond to a minimum layer thickness of the cohesive connection. In one variant, the network security apparatus comprises a software entity disposed at least partly within the software stack of the devices.
