A device for treating exhaust gas containing soot particles includes at least one ionization element for ionizing soot particles, at least one filter element having at least one section to which an electric potential can be applied and at least one agglomeration unit for at least partial agglomeration of electrically charged soot particles. A first plurality of videoconferencing devices of a first type may be monitored. Zig-zag metal spacers between the two identical Photonic Band Gap crystal structures are used to form the electron beam vacuum gap. As a result, since the length of the address chain corresponding to the output ports may be adjusted in accordance with the use frequencies of the output ports, the address storage memory can be effectively used, depending upon a plurality of output ports. The data is clocked into the second receiver by the second clock signal. The control apparatus may determine an acceleration value for the traction motor based on at least one of an angular position of the steerable wheel, a speed of the traction motor and a current position of the speed control element as defined by the speed control signal.
