摘要： A method, actuating device, and microsystem device are described for controlling a micromechanical actuator, which has a rechargeable capacitor for generating a mechanical motion of the micromechanical actuator, a memory having a lookup table containing previously computed data of signal shapes for controlling the micromechanical actuator, and a driver circuit having a driver circuit control unit for processing the previously computed data, a power stage for generating the signal shapes, and an output for outputting the signal shapes, corresponding to previously computed data, to the micromechanical actuator's rechargeable capacitor. The micromechanical actuator has a limiting device, between the output of the driver circuit and the micromechanical actuator, which is for limiting a voltage excursion of the signal shapes output by the driver circuit, which are usable for generating the mechanical motion by recharging the micromechanical actuator's rechargeable capacitor. The micromechanical actuator's power consumption is reducible by limiting the voltage excursion.

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.
