摘要： A sensor, particularly for automatic release of occupant safety devices in power vehicles in the event of an accident, the sensor comprises a housing which forms a closed chamber; a body located in the housing and formed as a seismic mass, the closed chamber of the housing being completely filled with a fluid, the body being formed as a pendulum of a predetermined length, the chamber having a wall on which a boundary layer of the fluid is formed, the chamber having in all swinging direction of the pendulum a radius which is greater than the length of a pendulum and the boundary layer of the fluid formed on the wall of the chamber, the pendulum and the fluid having specific weights which differ from one another, the pendulum and the fluid being selected so that a friction during movement of the pendulum relative to the fluid leads to an aperiodecal damping of the pendulum.

摘要： An apparatus for the automatic release of passenger protection devices in motor vehicles in the event of an accident has a sensor (35) having a mass (10) secured outside the center of mass (11). This mass (10) generates a comparably high torque in the suspension in the event of both positional change and rotational acceleration. These torques are detected with known measuring methods and split, with the aid of a high-pass filter (36) and a low-pass filter (40), into a high-frequency and a low-frequency portion. The high frequency portion corresponds to the rotational acceleration, from which the rotational velocity is obtained by means of an integrator (38). The low-frequency portion corresponds to the position of the motor vehicle. Thus both measurement variables that must be detected for releasing a roll bar are obtained with a single sensor (35).

摘要： Disclosed is a method of and a device for controlling a burn-off function of a measuring resistor, particularly heated wire or heated film in an air flow sensor of an internal combustion engine. The burn-off operation for fast cleaning the measuring resistor is normally made either periodically or in response to preset operational conditions of the engine. The invention interrupts this burn-off function when detrimental operational condition of the engine depending on the rotary speed has occurred. The stoppage of the burn-off function preferably occurs after a simultaneous detection of a predetermined temperature value detected by a sensor.
