In order to efficiently present data extracted from a captured image of an assessment document, a single bitmapped composite image is constructed from multiple images or components such that each layer or content type is stored within discrete bits within each pixel. The method utilizes differential staining of nucleated and non-nucleated blood cells, and also differential labeling of cells with functional versus dysfunctional mitochondrial membrane potential. Slot machines can then be updated electronically according to the ideal settings, either automatically or upon operator approval. Cooperating instrumentalities maintain and position the extractor pin relative the tool such that, when a force is applied to the tool, the free end of the shank portion of the pin engages with and forcibly extracts the retaining pin from the digging tooth. The sensing signals are automatically transmitted to at least one remote viewer, and a viewable image of the aiming reference is displayed from the sensing signals. Finally, a gate conductor is filled into the recessed structure and an N-type source doped region is formed around the gate conductor in the P-type epitaxial layer.
