A cassette includes a shell having a plurality of shielded channels extending between a front and a rear of the shell. Articles that include a porous substrate and the hot melt adhesive composition. The retaining portion has a soldering leg extending downwardly and vertically therefrom, which is connected electrically to a cable. The quick release operates by shear of hook and loop type fasteners, and may use other types of attachment means instead of or in addition to the hook and loop. If the comparison is not favorable, then the application thread enters a sleep state; after awakening, it repeats the comparison, and depending on the result, it transmits a message or reenters a sleep state. This advantageously reduces the number of required interconnects between the first and second devices by one half.
