A method for producing a multilayer component is described. The output driver circuit is configured to drive a given column output for the plurality of columns of LED devices in response to being activated based on data and an driver on signal supplied to the output driver circuit. Cross braces are disclosed which extend transversely across the side walls, and which extend into the upper webs of parallel side walls. Therefore, each module of the system can avoid any message traffic congestion and, consequently, the stability of the whole system can be greatly enhanced. In various embodiments, ternary switching may be used in combination with binary switching to efficiently implement multi-state rotary or linear switches capable of identifying six, twelve, eighteen or any other number of switchable states. The instrument operates in a pulsed operating mode wherein relative instrument-to-eye motion is reduced and, preferably, nearly eliminated.
