Serial concatenated trellis coded modulation includes an outer coder, an interleaver, a recursive inner coder and a mapping element. An additional contact module is connected to the electronic unit, the drive motor being electrically connected only to the contact module. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components. The areas are spaced apart from one another in a non-overlapping relationship. When forming a color filter layer composed of plural color filter plates in delta arrangement, the overlapping area of three adjacent color filter plates can be lowered.
