摘要： The invention proposes a method for determining a rotation angle or distance by evaluating a multitude of phase measurement values. By means of a linear transformation A, the phase values measured in an N-dimensional space are projected into N-1 new signals Si. These signals Si are transformed by a quantizing device into corresponding integer values Wi and converted into N real values Zi by means of a linear projection C. These values have weighted phase measurement values &agr;i added to them in modulo 2&pgr; fashion, which yields N estimates for the angle &phgr; to be measured. The N estimates are corrected if needed at their skip points and are added up in a weighted fashion, taking into account their phase angle.

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 and a circuit arrangement for the start-up of a rate-of-turn sensor (DRS) comprising at least one oscillator element are disclosed, wherein the operational control of the rate-of-turn sensor amplifies a signal (v(t), x(t)) proportional to the instantaneous speed or deflection of the oscillator element used as operating signal (F(t)) to operate the oscillator element. During the start-up process for the rate-of-turn sensor (DRS) the amplification of the amplitude (AF) of the operating signal (F(t)) is set to a constant pre-settable value (AFC) the stimulation frequency of the operating signal (F(t)) being essentially continuously raised from a starting value (f1) below the main resonance frequency of the oscillation movement to a final value (f2) above the main resonance frequency and below a spurious resonance frequency with simultaneous monitoring of the deflection (x(t)) and/or the speed (v(t)) of the oscillator element, in order to determine the main resonance frequency. After reaching the final value (f2) and the main resonance frequency determination, the stimulation frequency of the operating signal (F(t)) is set to the main resonance frequency and the operational regulation of the amplitude and the stimulation frequency of the operating signal (F(t)) released.

摘要： A capacitive sensor includes a plurality of individual condenser elements, each of which consist of a first, preferably circular, electrode and a second, preferably surrounding ring-shaped, electrode, which are mounted on one side of a nonconducting support. A common conductor is connected to each of the first electrodes of condenser elements. A signal can be detected separately from each of the condenser elements via conductors connected separately to the individual second electrodes. To increase the sensitivity and to avoid interference, the remote side of the support opposite to the one side is provided with a third additional electrode, which is at ground potential and also acts as a shield for interfering couplings. The sensor is used for measurement of the fuel film thickness in the intake of an internal combustion engine.
