A system for analyzing fabric surface appearance includes a feed mechanism for running a fabric over a crest including a frame for holding the fabric bent to form a crest, an image capturing device for capturing profile images of the fabric surface at the crest, and a computer system for manipulating the images. Preferably, the coating is a secondary coating or, in the case of a ribbon of optical fibers, it is a common polymer coating known as a \u201ccommon coating\u201d. The gaming system also detects physical objects placed on the surface of the gaming table, causing wagering game functions or peripheral functions to be performed as a result of the placement of the object on the display surface. The plurality of second level shifters each has a shutdown function for reducing the power consumption of the level shifters. The left and right side convergent upper panels are in sealing engagement with the left and right side divergent upper panels along left and right side upper interfaces, respectively. Each of a plurality of viaholes electrically connecting conductor circuits on the insulating layers to each other is formed tapered inwardly from the surface of the insulating layer and the viaholes are disposed opposite to each other to form a multistage stacked vias.
