A surface acoustic wave resonator includes a rotated Y-cut quartz substrate with a cut angle \u03b8 of about \u221253\xb0 to about \u221252\xb0 and an IDT electrode made of aluminum or an alloy primarily including aluminum provided on the quartz substrate. The amplifying circuit employs a voltage converter to adjust the supply voltage, thereby upgrading the energy efficiency of the circuit. This method and system has capability to effectuate point of use control of the stored articles through a database in the computer system. The method then concatenates the patches to produce processed mission and reference images, and subtracts the processed mission and reference images to form a delta image. The lookup table stores a plurality of LZ77 code segments and outputs one of the LZ77 code segments corresponding to an index at least partially derived from a comparison result from the set of comparators.
