There exists a tendency in the construction of combustion devices to employ a multi-level, spatially distributed feed of the combustion air in order to be able to better influence the stoichiometric ratios during the combustion. Hybridization cells for use with the individual test strip arrays are also disclosed, and in particular embodiments the hybridization cells closely fit a portion or all of the individual test strip arrays. The semiconductor switch is configured by connecting a thyristor and a thyristor in anti-parallel with each other. Further, the polarity force component of the surface free energy of each of the first and second alignment layers is 13 dyncm or less. Hinges comprise an inverted rectangular U-shape in section in geometry.
