    摘要: The invention relates to a circuit assembly for operating a sensor array, in particular, a gas sensor array for detecting gases, which comprises at least one signal line. According to said invention, a signal line is divided into two parallel line branches with a sensor and a diode, preferably a Schottky diode, arranged in each of said two parallel line branches, whereby the two diodes have opposite electrical polarity. The use of different polarity diodes permits actuation of both sensors through only one signal line. It can be determined if the current flows through one or the other of both sensors by merely polarizing the electrical potential applied to the signal line appropriately.

    摘要: The invention relates to a method for unambiguously determining a physical parameter Φ using m phase-measured values αi with 1≦i≦m, whereby the phase-measured values αi have different, integer periodicity values ni and an integer periodicity difference (a) with Δn>1 within an unambiguous range E of the physical parameter Φ. A value T with (b) and (c) is calculated based on the phase-measured values αi and the periodicity values ni thereof, and, within a reduced unambiguous range Ered with (d), a value V is allocated to the value T by allocation according to (e), wherein TUk stands for a respective lower limit and TOk for a respective upper limit of T. The allocation intervals between the upper (TOk) and the lower limits (TUk) for T, as wells as the distances (f) correspond at least to the periodicity difference Δn. In order to determine the physical parameter Φ, value V is added up with the C phase-measured values αi in a weighted manner.

    摘要: A scanner-control device for scanning an echo signal formed by returning transmit pulses, includes a clock generator, which triggers a pulse shaper for the transmit pulses and a further pulse shaper for scanning pulses. The scanner-control device also includes setting member for modifying a delay time of the scanning pulses, so that the echo signal can gradually be reconstructed from the returning transmit pulses. Temporally stable transmit pulses and scanning pulses, that are also in a temporal relation to each other, are achieved through the fact that the pulse shaper for the transmit pulses is an element of a first closed loop having a summing point and having a controller, and the further pulse shaper is an element of a second closed loop having a further summing point and a further controller, and that the summing point and the further summing point have supplied to them an identical setpoint value, and the further summing point has additionally a further setpoint value, which is varied to alter the delay time.

    摘要: For operational control of a start-up of a rate-of-turn sensor including at least one oscillator element that is excitable to perform a mechanical oscillating motion, a signal proportional to the instantaneous speed or deflection of the oscillator element is amplified and used as the operating signal to operate the oscillator element, during the start-up process for the rate-of-turn sensor, the amplitude of the operating signal is set to a constant specifiable value, the stimulation frequency of the operating signal is increased essentially continuously from a starting value below the main driving frequency of the oscillating motion to a final value above the main driving frequency and below a spurious driving frequency while, simultaneously, the deflection and/or the speed of the oscillator element are monitored in order to determine the main driving frequency of the oscillating motion, once the final value is reached and the main driving frequency is determined, the stimulation frequency of the operating signal is set to the main driving frequency, and the operational regulation of the amplitude and the stimulation frequency of the operating signal are released.
