    摘要: A sensor for determining the concentration of particles in gases, in particular of soot particles, has at least one substrate element, and a measuring area between at least one first and one second measuring electrode, the two measuring electrodes being configured so that by applying a voltage between the measuring electrodes, an asymmetric electric field is formed on the measuring area. The sides of the first and second measuring electrodes, facing one another, may not be parallel to one another, for example. Furthermore, at least one measuring electrode may have a structure along the side facing the other measuring electrode or along the finger electrodes.

    摘要: The invention proposes a method for determining a rotation angle (&PHgr;) and/or an angular difference (&dgr;) in a divided shaft (3), which has a number of phase tracks (1a, 1b, 2a, and 2b) disposed on it, which are provided with codes. Via an evaluation unit, each group of tracks (1a, 1b, 2a, and 2b) supplies a phase signal (&agr;1, &agr;2), which is respectively ambiguous with regard to a rotation of the shaft (3). The at least two phase signals (&agr;1, &agr;2) are added up in a weighted fashion to produce a signal S from which the integer portion and the non-integer portion are calculated. The non-integer portion is proportional to the angular difference (&dgr;) between the two track groups. The torque (M) is determined through multiplication with the spring rate of an interposed torque rod. The unambiguous torque (&PHgr;) is determined from the integer portion of the signal (S) and a phase value (&agr;1) or (&agr;2) with the aid of a weighted addition.

    摘要: A method is described for controlling the soot deposition on sensors. A sensor element is provided, which includes a first electrode and a second electrode. Different measuring voltages U1 and U2 can be applied to the sensor element. During a first time period t1, the sensor element is operated at a higher voltage U1 until a triggering threshold AP of the sensor element is exceeded, while it is operated at a voltage U2, which is different from higher voltage U1, U2 being lower than voltage U1, during a second time period t2.
