    • A microphone amplifier comprises an input terminal (E100) for applying an input signal (IN), an output terminal (A100a) for outputting an output signal (OUT), and an additional output terminal (A100b) for outputting an additional output signal (VBIAS). The microphone amplifier also contains an amplifying circuit (10) for generating the output signal (OUT) by amplifying the input signal (IN), wherein the amplifying circuit (10) is connected between the input terminal (E100) and the output terminal (A100a), and a voltage generator (30) for generating the additional output signal (VBIAS). A supply voltage terminal (V30) of the voltage generator (30) is connected to the output terminal (A100a) of the microphone amplifier. Since the amplifying circuit (10) makes available a supply voltage (V) for the voltage generator (30), the microphone amplifier can be operated without a separate supply voltage terminal.
    • 麦克风放大器包括用于施加输入信号(IN)的输入端(E100),用于输出输出信号(OUT)的输出端(A100a)和用于输出附加输出信号(VBIAS)的附加输出端(A100b) )。 麦克风放大器还包括用于通过放大输入信号(IN)来产生输出信号(OUT)的放大电路(10),其中放大电路(10)连接在输入端(E100)和输出端(A100a )和用于产生附加输出信号(VBIAS)的电压发生器(30)。 电压发生器(30)的电源电压端子(V30)连接到麦克风放大器的输出端子(A100a)。 由于放大电路(10)为电压发生器(30)提供电源电压(V),所以麦克风放大器可以在没有单独的电源电压端子的情况下工作。

    • The invention relates to a lighting device for a motor vehicle. Said lighting device comprises a light source (1; 96) for emitting electromagnetic radiation, in particular light which is visible to the human eye, and a reflector (70; 81; 90) for focusing the emitted light. The light source (1; 96) is fastened on the reflector (70; 81; 90) at least indirectly in a defined position relative to a reflective surface of said reflector. In order firstly to make heat transfer from the reflector (70; 81; 90) to the light source (1; 96) more difficult and secondly to enable EMC shielding by virtue of an electrical contact between the light source (1; 96) and the reflector (70; 81; 90), the invention proposes that a material (72) with poor thermal conductivity is arranged between the reflector (70; 81; 90) and the light source (1; 96) for thermally insulating the light source (1; 96) from the reflector (70; 81; 90). Preferably, the material (72) has a thermal conductivity λ of less than 2 W/mK and a relative permittivity (εr) of greater than 1.
    • 本发明涉及一种用于机动车辆的照明装置。 所述照明装置包括用于发射电磁辐射的光源(1; 96),特别是对人眼可见的光,以及用于聚焦发射光的反射器(70; 81; 90)。 光源(1; 96)至少间接地在相对于所述反射器的反射表面的限定位置处紧固在反射器(70; 81; 90)上。 为了首先使得从反射器(70; 81; 90)到光源(1; 96)的热传递更加困难,其次是通过光源(1; 96)和 反射器(70; 81; 90),本发明提出,在反射器(70; 81; 90)和光源(1; 96)之间布置有导热性差的材料(72),用于将光源 (1; 96)从所述反射器(70; 81; 90)。 优选地,材料(72)具有小于2W / mK的导热系数λ和大于1的相对介电常数(& r)。

    • A method for system- and/or process-monitoring in the case of an ultrasound flow measuring device having a plurality of measuring channels, wherein a medium flows though a pipeline or measuring tube in the direction of a longitudinal axis of the pipeline or measuring tube. Ultrasonic measuring signals are coupled into the pipeline or measuring tube and coupled out of the pipeline or measuring tube in such a way that they travel through the medium along different sound paths. Following passage through the pipeline or measuring tube, the ultrasonic measuring signals are detected in the individual measuring channels, wherein at least one actual quantity describing the ultrasonic measuring signal of each measuring channel is ascertained. The actual quantity is compared with a desired quantity captured under predetermined system- or process-conditions, and a report is output in the case of a difference between the ascertained, actual quantity and the captured, desired quantity.
    • 一种在具有多个测量通道的超声波流量测量装置的情况下进行系统和/或过程监视的方法,其中介质沿管线或测量管的纵向轴线的方向流过管道或测量管 。 超声波测量信号被耦合到管道或测量管中,并且以这样的方式耦合到管道或测量管外,使得它们沿着不同的声音路径行进通过介质。 在通过管道或测量管之后,在各个测量通道中检测超声波测量信号,其中确定描述每个测量通道的超声波测量信号的至少一个实际量。 将实际数量与在预定的系统或过程条件下捕获的期望数量进行比较,并且在确定的,实际的数量和所捕获的期望数量之间的差异的情况下输出报告。
