    摘要: A device structure is made using a first conductive layer over a first wafer. An isolated conductive region is formed in the first conductive layer surrounded by a first opening in the conductive layer. A second wafer has a first insulating layer and a conductive substrate, wherein the conductive substrate has a first major surface adjacent to the first insulating layer. The insulating layer is attached to the isolated conductive region. The conductive substrate is thinned to form a second conductive layer. A second opening is formed through the second conductive layer and the first insulating layer to the isolated conductive region. The second opening is filled with a conductive plug wherein the conductive plug contacts the isolated conductive region. The second conductive region is etched to form a movable finger over the isolated conductive region. A portion of the insulating layer under the movable finger is removed.

    摘要: To transmit data which is supplied by a rotational speed sensor in the form of an alternating signal as well as additional data via a signal line, a sequence of current pulses of a predetermined duration is derived from the alternating signal, the pulse intervals or interpulse periods containing the information on rotational speed. The additional data is transmitted in the interpulse periods, and transmission of the additional data is synchronized by the individual rotating signal sensor pulses. Preferably, the method is employed for active sensors, and both the sensor pulses and the additional data are transmitted in the form of current signals. During standstill, in the absence of a sensor pulse, transmission of the additional data is triggered by auxiliary synchronization pulses.

    摘要: To process the output signal of a rotational speed sensor (2) which generates an alternating voltage dependent in respect of frequency and amplitude on the rotational speed, two low-pass filters (TP1, TP2) serve to produce a useful signal (I1), on the one hand, and a reference signal (I2), on the other hand. The two signals are compared. In dependence on the difference of these signals (I1, I2) a pulse-shaped output signal, namely the processed sensor signal, is generated by means of a comparator (7). The reference signal dynamically follows the useful signal with the aid of a control signal issue by an adapter circuit (20,21).

    摘要: In normal operation, a sensor element emits information only as to whether two or more field-sensitive components are located in peripheral zones of identical or different electromagnetic field strengths of a pulse generator. In order to permit sensor elements of this type determining immediately upon activation of a supply voltage whether an identical electromagnetic field strength on both components corresponds to a zone of low (L) or high (H) field strength, according to the present invention, the sensor element, upon activation of the supply voltage, is initially operated so that the absolute field strength is measured for a given time. If there is a difference circuit between two field-sensitive components (3, 4), the measurement is carried out because one of the components is temporarily switched off, both components are connected in parallel, or both components are connected in series.

    摘要: A circuit configuration which serves to condition the output signal of a rotational speed sensor, e.g., the wheel sensor of an automotive vehicle. The circuit configuration includes a trigger circuit, the "hysteresis" or trigger thresholds thereof being controllable, and includes circuits for determining a coupling factor which, multiplied by the frequency of the sensor signal corresponding to the speed of rotation, forms the amplitude of the sensor output signal. To determine the coupling factor, and to adjust the hysteresis, threshold values are predefined for the output signal of the rotational speed sensor. Upon start of the vehicle, the coupling factor is determined from the frequency of the sensor signal at the point of time the threshold values are reached, and the hysteresis is adjusted accordingly.

    摘要: To avoid dangerous pressure decreases in antiskid systems, it is necessary to continuously monitor the operability of the electrical components. The present invention ensures maximum reliablity and a simple circuit configuration. Electrical signals are generated during the period of time in which a pressure decrease occurs and/or by the speed of pressure decrease at each wheel of a vehicle axis and are subtracted from one another. If the absolute value of the difference reaches a limiting value, the disturbed part of the system will be prevented from causing a further pressure decrease.
