A novel spatial light modulator system has a high fill factor MEMS array of tilting mirrors used to attenuate wavelength channels in an optical network and an interface control circuit controlling the tilting mirror array via received control signals. A stitching line is applied to access and seam the front end of an upper junction circumference of a cover portion, a bottom end of the steel head, and the front end of a lower junction circumference of a sole together to ensure the durability of the steel-head shoes. When a cross-section of the lower electrode is examined in the thickness direction using secondary ion mass spectroscopy, a ratio Z1 Z2 between the intensity Z1 of oxygen ions and the intensity Z2 of ions of a precious metal detected at the surface of the lower electrode facing the substrate is 0. A connector; a signaling assembly, including a signaling medium and connector; a circuit board; and a signal communication system are also disclosed. The execution unit is capable of engaging in one of a number of operating modes to perform the bit-oriented functions.
