Comparing usage of items at a location associated with a sensor network to attributes of a selected item is disclosed. The apparatus includes a fixture with a mounting surface adapted to receive the microstructure device. The stripping member is positionable relative to the first nip to vary a pressure applied by the outer surface of the belt against the first outer surface downstream from the first nip. Also, a method is provided for characterizing a deformed pattern in an image by using results from feature-based search tools to create a mapping that models the deformation of the pattern. The implant has at least one passage therethrough from the upper wall to the lower wall to promote fusion through the implant.
