Apparatus, methods, and other embodiments associated with a mining and demolition tool are described herein. The shank is adapted to enable it to be driven through at least a first course of roofing material and into a roof deck. Synchronization registers synchronize partial product and multiple modulus values input to an accumulator reducing glitch andor increase computation speed. The syncasync bit is included in at least one of the acquisition pilots. In one embodiment, an image captured with use of an image capture device is an image of an item bearing a decodable indicia. While the path is enabled, at least one switched voltage is connected to vary an amount of the current conducted through the path.
