RFID reader antennas and methods for generating magnetic fields. A new and novel tangible item, such as \u201cA\u201d pillar garnishment 18, having programmed energy absorption characteristics is also disclosed. A first simplification mode for the initial design is selected from a set of applicable simplification modes, wherein the first simplification mode is an XORXNOR simplification mode, and a simplification of the initial design is performed according to the first simplification mode to generate a reduced design containing a reduced number of XOR gates. The ultrasonic oscillator provides energy to the high-pressure water and the water knife is utilized to clean residue off the polishing pad. The reaching arm is composed of two sections: a front section and a rear section.
