The present invention relates to a parallel fan. The structure is exposed to a fabrication process environment conditions of which are selected to alter an extent of the gap. The solder bond between the base plug and the cartridge case within which it is held is capable of resisting the from about 72,000, to up to 90,000 psi, force generated within the firing chamber of the weapon by the ignition and firing of the cartridge. The nozzle openings adjacent the periphery of the separator plate overlie a surface of the housing adjacent the outlet. The wireless communication device may also be coupled to the energy source for power. The upper substrate is stacked on one side of the mirror layer while securing a first space between the center of the mirror surface and the first and second upper electrode parts, while the lower substrate is stacked on the other side of the mirror layer while securing a second space between the center of the mirror surface and the first and second lower electrode parts.
