    • A force/torque sensor has a semiconductor region which is adapted to be subjected to a force or torque. Two control electrodes are provided on a first and a second side of the semiconductor region, the sides being arranged in spaced, opposed relationship with one another, and a current through the semiconductor region being producible between the control electrodes. Two sensor electrodes are provided on a third and a fourth side of the semiconductor region, the sides being also arranged in spaced, opposed relationship with one another and extending essentially at right angles to said first and second sides. A force or torque applied to the semiconductor region is determinable by detecting a voltage present between the sensor electrodes when a current flows between the control electrodes. The semiconductor region is formed by the channel of a field effect transistor, the drain an source electrodes of said field effect transistor defining the control electrodes.

    • A process for simultaneous transmission of signals from N signal sources via a corresponding number of transmission channels, in which the individual signals are divided into blocks and the blocks are transformed into spectral coefficients by transformation or filtering, the spectral coefficients undergoing a data reduction process. The blocks belonging to the individual signals are divided into sections. The respective current sections of all signals are processed simultaneously. The permissible interference for each section is determined utilizing a perception-specific model, and a request of currently required overall transmission capacity is calculated. The allotment of maximum transmission capacity at disposal for each individual signal is calculated from the overall transmission capacity at disposal and the currently required overall transmission capacity. Each signal is coded and transmitted with the thus determined capacity.

    • In a method for assessing the quality of an audio test signal derived from an audio reference signal by coding and decoding, the audio test signal is compared with the audio reference signal, as it were, behind the cochlea of the human ear. All masking effects as well as the transmission function of the ear are equally applied to the audio reference signal and the audio test signal. To this end, the audio test signal is broken down according to its spectral composition by means of a first bank of filters consisting of filters overlapping in frequency and defining spectral regions, said filters having differing filtering functions each determined on the basis of the excitation curve of the human ear with respect to the respective filter center frequency. The audio reference signal is also broken down according to its spectral composition into partial audio reference signals by means of a second bank of filters coinciding with the first bank of filters. Subsequently, a level difference by spectral regions is formed between the partial audio test signals and the partial audio reference signals belonging to the same spectral regions. To assess the quality of the audio test signal, a detection probability is determined, by spectral regions, on the basis of the respective level difference so as to detect a coding error of the audio test signal in the spectral region concerned.
    • 在通过编码和解码来评估从音频参考信号导出的音频测试信号的质量的方法中,将音频测试信号与音频参考信号相比较,在人耳的耳蜗之后。 所有掩蔽效应以及耳朵的传输功能同样适用于音频参考信号和音频测试信号。 为此,音频测试信号根据其频谱组成通过由频率重叠的滤波器组成并定义频谱区域的第一组滤波器进行分解,所述滤波器具有不同的滤波函数,每个滤波函数基于激励曲线确定 相对于滤波器中心频率的人耳。 音频参考信号也根据其频谱组成分解为部分音频参考信号,借助于与第一组滤波器重合的第二组滤波器。 随后,在部分音频测试信号和属于相同光谱区域的部分音频参考信号之间形成由频谱区域的电平差。 为了评估音频测试信号的质量,通过频谱区域基于各个电平差来确定检测概率,以便检测相关频谱区域中的音频测试信号的编码误差。
