An assembly machine display has an image representative of a workpiece to be assembled using the machine. The data queue operates on first-in-first-out principals, and has a variable width input and output. The crosslinker can be included in a coating composition with one or more curable resins, applied onto a substrate and cured to form the cured coating of the invention. By the learning, an inputoutput function representing the relationship between the input and output values is defined and stored in the learning storage unit. The centrifuge is controlled responsive to the inferred position of the phase interface. The control signal output pin may be configured to provide a control signal indicative of the memory interface control flow including, for example, an availability of the memory array for reading or writing.
