A method and apparatus for detecting substrate arcing and breakage within a processing chamber is provided. The cathode layer includes a carbon layer containing carbon particles, and a conductive paste layer containing conductive metal particles and having numerous pores, formed in that order from the solid electrolyte layer side. The support structure is axially movable relative to the support frame for moving the external load so as to control the center of gravity of the aircraft and so as to deploy and retrieve the external load. The plurality of fins are thermally coupled to the condenser sections of the plurality of heat pipes. Neuro-respiratory signals are analyzed using means to extract more accurate definitions of the frequency and severity of sleep discontinuity, sleep disordered breathing and patterns of sleep architecture. The opposite end of air supply tubing is connected to one or more air nozzles.
