A programmed computer and method are described for generating a processor design. The controller is configured to receive and analyze the image data, to generate a control signal that is used to control the equipment, and to automatically aim the image sensor. The gas washout vent assembly includes at least one gas washout orifice extending from a first side of the vent assembly positioned, in use, adjacent the human or animal’s face and a second side positioned, in use, adjacent the atmosphere. The cutoff frequency and bandwidth of the first receive filter is controlled independently of the second receive filter to enable the output of the first receive filter and the output of the second receive filter to be tightly matched. The temperature sensing elements are disposed in one or more void spaces in the non-fuel cell cassette, which void spaces are connected to openings in the side of the non-fuel cell cassette for lead wires to communicate information from the temperature sensing elements to components outside of the fuel cell stack.
