摘要： In a method for the detection of local displacements and rotations, a sum signal and additionally a difference signal are formed from two separately generated signals of two transducer elements (W1, W2), which are spaced from each other, and subsequently the formed sum signal and the formed difference signal are OR-operated. A device for doubling the local frequency of moving incremental scales comprises an encoder (1a, 1b, 1c), a magnetically sensitive transducer (9, 13), and a signal conditioning stage (6a, 6b) electrically connected thereto. The transducer comprises at least two sensorially active functional groups synchronously using sensorially active groups or sub-groups (W1, W2) which are locally offset in relation to each other by a local phase φ in order to scan the moving scale, and the functional groups comprise means enabling at least two independent partial signals S1=V*sin(ωt) and S2=−V*sin(ωt)+φ) to be produced.

摘要： A device for detecting the rotational behavior of a vehicle wheel includes an encoder with permanent magnet areas, a stationary measurement transducer sensitive to magnetic fields, and electric circuits for evaluating the output signals of the measurement transducer. The permanent magnet areas are embedded into the tire wall of the vehicle wheel or applied to the tire wall. The measurement transducer includes two or more measuring elements which are arranged at a different radial distance from the axis of rotation and positioned in such a manner that upon distortion of the tire as a result of forces acting upon the tire, there is a change of the phase position between the measurement signals issued by the measuring elements. This change of the phase position is evaluated as a measure of the torque transmitted from the wheel to the road surface and/or as a measure of the instantaneous coefficient of friction.

摘要： A method and device are disclosed for determining and checking a state or condition of a hydraulic fluid contained in a brake system, including a state of hydration and/or age such that the fluid boiling point is reduced. The boiling point or a characteristic value of the fluid which depends on the boiling point, on the one hand, and the instantaneous temperature value of the fluid, on the other hand, are measured by means of sensor elements. These two values represent a range of permissible comparative temperature values, including a thermal reserve which is within that same range and is determined for further permissible heating of the fluid. A warning signal is released when a predetermined minimum value of the thermal reserve is reached. The sensor elements have hollow spaces with open walls permitting fluid flow-through and have such a design as to ensure that, after heating-up, there comes about a stable cellular convection in a temperature range lying below the boiling temperature. The cellular convection is used as an indication of the condition or the state of the fluid.

摘要： Disclosed is an arrangement for detecting rotational speed of a wheel or any other rotating body by a sensor (1, 6), which is coupled via a magnetic field to an encoder (23) that rotates with the rotating body. If a slot between sensor element (S1, S2) and encoder (23) becomes too small in the prior art arrangements, flipping and, hence, doubling of the measured rotational speed of the wheel can occur. This caused problems in safety devices of a vehicle, which require a correct indication of the wheel rotational speed for proper operation. To improve the tolerance with respect to the mounting position of the known arrangements, two separated signal paths (S1, f1; S2, f2) are provided with sensor elements (S1, S2) of differing sensitivity. The signal paths (S1, f1; S2, f2) are designed so that a signal path (S1, f1) is always available, which is provided with a maximum rate of sensitivity so that, in the undisturbed normal case, minimum image defects of the encoder track (13) are achieved, simultaneously with maximum air slots, while at the same time there is always an observing signal path (S2, f2), whose sensitivity is rated in such a way that flipping is safely prevented in all magnetic conditions.

摘要： Disclosed is an arrangement for the intrinsically safe detection of movements of a body, such as a wheel. The arrangement includes a magnetic encoder (5, 25) and a sensor (26), the magnetic encoder (5, 25) moving with the body and is magnetically coupled to at least two sensor elements (S1, S2) of the sensor (26) via a magnetic air gap. The sensor (26) has at least two mutually separate signal paths (S1, f1; S2, f2) which have at least one of the sensor elements (S1, S2) and a signal conditioning stage (28, 29). A primarily measuring signal path (S1, f1) is constructed so that during normal operation represents an output signal the basic frequency of the encoder movement or the temporal profile of the output signal have patterns. The temporal occurrence of the patterns correspond to the basic relative speed between the sensor (26) and the pole pairs of the encoder (5, 25) which are detected by the sensor.
