A certification system and method for inspecting of a roll of web material through a web inspection system which includes the inspection of the roll of web material to determine the number, type and location of one or more detectable flaws along the web material. The control circuit is configured to detect an interactive application operating on a remote device. The improvement relates in part to the incorporation of a clock divider that reduces the frequency of the clock signals utilized by the system. In embodiments the canopy can be positioned to contain the collapsed frame and chair in the carrying position. A closure element is formed on the molding body so as to at least partially close off the latching recess. At least one projection projects from the bottom surface of the receiving slot.
