摘要： The invention relates to a method for determining the ground clearance of an automobile, including a step that comprises deriving (260) the ground clearance of the automobile from the output voltage (Vout) of a sensor (28). The invention comprises: using, as a sensor (28), an electric generator comprising an electromechanical transducer comprising at least one layer of an electro-active polymer material (10) arranged between at least one pair (100, 110) of electrodes (12, 12', 14, 14'), wherein said layer (10) and the electrodes are integrated into a bellow (2) made of a flexible material that surrounds a link between two non-aligned shafts (4, 6) and is rotatingly driven with the latter, the layer (10) of electro-active polymer material and the electrodes (12, 12', 14, 14') extending longitudinally relative to the shafts; recording (200) the peak value of the output voltage (Veap) of each pair of electrodes (100, 110) after scaling (Vsc); selecting (210) a pair of electrodes from said pairs; and setting (220) the output voltage (Vout) of the sensor (28) on the basis of the output voltage (Vsc) of the selected pair of electrodes.

摘要： The invention concerns an angular position sensor. This sensor comprises a rotating part (14), which creates a variable magnetic flux, a fixed part (16) that supports two probes (22, 26) each having a current output. A first probe (22) has a current output having discontinuities when the magnetic flux passes to zero. The second probe (26) is subjected to a second magnetic flux that is out of phase by 90 DEG with regard to the first flux and has an output current that is a continuous function of the magnetic flux. The sensor also comprises a summing device (30) for adding the currents of the two probes. The variation range of the current of the first probe (22) is slightly greater than the variation range of the current of the second probe (26). The inventive sensor is for use on engine camshafts.
