A system and method to organize information on the internet for rapid and organized retrieval. In the triangular pyramidal cube corner retroreflective article, a triangular pyramidal cube corner retroreflective element pair group is disposed in a closest-packed fashion on a common plane defined by three base lines, and the each of retroreflective elements in a pair having one base line shared by the retroreflective elements in the pair. Disposed within the housing can be at least one metal member that is positioned underneath or in proximity to the cutting edge of the tool. The oval-shaped discharge opening is substantially smaller transversely than the diameter of the inlet opening, but has a longitudinal length that is equal to the diameter of the inlet opening and equal to the longitudinal length of the wash decks. Any remaining unreacted part of the receptor element is removed and the second chemical agent washed away in the higher solubility areas thereby producing the screen-printing stencil. The operation signal output device includes a wireless transmitter.
