Embodiments of an X-ray diagnostic imaging system comprise a plurality of coded 2D andor 3D markers associated with surfaces of system components. The demodulator controls the RF_AGC and IF_AGC tuner gains according to an AGC characteristic of the tuner, to provide a constant level of the IF_OUT signal. The second region is of the second conductivity type and is formed in the first well. Metal plate output terminals are attached to both ends of a battery module in a manner that is perpendicular to, and projecting from the battery end-planes. Finally, a methanol stream is isolated and a solvent stream is recycled to the reaction zone. In one embodiment, a plurality of different data strings are initialized building a symbol array, and finding differences within the data by analyzing various relationships within the data strings, such as the existence of unique strings.
