A fiber optic cable is provided with an outer jacket material having a coefficient of thermal expansion less than approximately 6E-5 in the range from 23 C. A carbon nanotube array is provided. A rotatable bowl selector dial which positions a flame inlet over one of the plurality of bowls in an adjacent smoking material retention cartridge offers a means for easy bowl selection. A recipe of an exposure equipment is adjusted based on the parameter value for exposure of the second substrate. At least one connecting member couples at least one of the upper and lower rings of the primary stabilizer assembly to a corresponding annular ring of the secondary stabilizer assembly. The voltage offset of the reference voltage is able to compensate for the offset voltage in the process of generating the pixel signals.
