A device for facilitating the correct measurement and placement of tiles having a transparent top plate for viewing indicia markings on bottom sliding plate, also having a channel for the setting of a rule that is angularly and spatially adjustable from the thin metal abutment edge through the loosening and tightening of a wing nut and washer attached to the ruler through said channel. Strength can be measured when the thumb or finger moves in at least two substantially opposing directions. The master can could be used to form arrays of sub-micron sized magnetic elements on a magnetic disk media for high-density magnetic recording applications. The carbon powders are aligned in a certain direction in the polymer matrix. The final contents of the buffer are then written to a log file at the appropriate logging level. Various methods, apparatuses andor articles of manufacture are also provided which may be implemented by one or more electronic devices to alter one or more electronic files used to support mobile device positioning within a specific environment.
