A light source that utilizes light emitting diodes that emit white light is disclosed. The memory can perform a number of functions when the tool is loaded on the tool manipulator: first, the memory can provide a signal verifying that the tool is compatible with that particular robotic system. A plurality of pad retaininglocating devices each have a pocket for receiving at least one of the plurality of internal pads so as to form an individual pad of the pad set. A vector processor is then used for quantization acceleration. The method may utilize a pre-weld heat treatment to grow a gamma prime precipitate phase in the superalloy material, a chill fixture to remove heat during welding, a relief cut to reduce stress in the root region, and a conventional post-weld heat treatment. 1-D processing makes the implementation easy while the top-down multiscale dot assignment can produce a multi-resolution halftoned image, which provides a good approximation of the original in multiple scales.
