  • Publication number: 20090288566
    Abstract: A method for producing printing stencils, especially for screen printing methods, and particularly those for use in filling at least one contact hole formed in a printed-circuit board, a pattern artwork being reproduced on the stencil, which corresponds to an arrangement of contact holes on the printed-circuit board. It is provided that the pattern artwork reproduced on the stencil be produced in the same working process, especially a punching process, using a cluster punching tool, as the at least one contact hole on the printed-circuit board. Also, a stencil device is provided.

  • Patent number: 6462566
    Abstract: A sensor element, in particular for determining an angle of rotation, has a detection medium whose position varies as a function of a change in a parameter to be measured, where the change in the position of the detection medium leads to a change in an analyzable signal of the sensor element which is influenced by the detection medium. The detection medium has at least one conductor loop carrying current which is exposed to an external magnetic field; the detection medium is rotationally movably mounted so that a rotational motion of the sensor element about an angle of rotation in the plane of the magnetic field is converted into a deflection of the detection medium perpendicular to the magnetic field.

  • Patent number: 6308554
    Abstract: An electronic device includes a resonant circuit and an evaluation circuit. The resonant circuit includes an acceleration-sensitive sensor which is excited to vibrate during a testing phase of the acceleration-sensitive sensor. The evaluation circuit is coupled to the resonant circuit to determine a performance reliability of the acceleration-sensitive sensor.

  • Patent number: 5940279
    Abstract: A metal support element having electronic components or circuit supports, in particular hybrid circuits, the connections of which are guided through from the component side, via a plurality of connector pins melted into glass passthroughs, to the opposite side of the support element. The connector pins are glass-mounted into pin blocks produced independently of the support element. The pin blocks are inserted into associated cutouts of the support element and fastened therein. The arrangement and number of the connector pins in the pin blocks can thereby be flexibly adapted to particular requirements with no need for modifications to the design of the support element. The material and the geometrical properties of the pin blocks can be optimally adapted to the glass-mounting process of the connector pins, while the material of the support element can be matched to the coefficient of thermal expansion of the attached circuit support.

  • Patent number: 5734107
    Abstract: An acceleration sensor having a piezoelectric sensor element, which is supported as a flexural resonator in a holding module and whose electrodes are connected to an evaluation circuit. The holding module mechanically fixes the sensor element in position and provides, at the same time, for its electrical contacting.

  • Patent number: 5510989
    Abstract: A system for influencing the travel dynamics of an automobile includes at least two sensor units (S1, S2, S3) for capturing the movements of the vehicle. First evaluation units (A1) evaluate the signals of the sensor units, these first evaluation units being spatially combined with the aforementioned sensor units to a sensor module (10). Connected with the first evaluation units by linkage mans (11), second evaluation units (A21, A22, A23, A24) process the signals processed in the first evaluation units, dependent on a regulation and/or control objective, to activation signals for actuators which influence the vehicle movements.

  • Patent number: 5499541
    Abstract: A piezoelectric force sensor includes a piezoelectric plate, with one electrode on each of the top and bottom sides of the plate. One of the electrodes is electrically connected via a conductor to a contact pad. In the case that the piezoelectric plate experiences breakage, the conductor is broken, and the remaining residual capacitance of the conductor and contact pad becomes so comparatively small that the breakage can be reliably detected.

  • Patent number: 5473930
    Abstract: An acceleration sensor, which is particularly adapted for use in motor vehicles, is improved by structuring it to be readily testable, to assure reliability before installation. The acceleration sensor has a piezo element (1), which consists of at least two piezo-electric plates (2) placed on top of each other, the piezo-electrical polarization of which is oriented in opposite directions. At least two electrodes (9) are placed on each of the topside (7) and the underside (8) of the piezo element (1). For testing the sensor, the piezo element is deformed by the application of an electrical voltage to electrodes (9) of a first lateral portion (11a) of the piezo element. This deformation is detected by means of a deformation-generated voltage at the electrodes (9) of a second lateral portion (11b) of the piezo element.
