Abstract: The invention relates to a micromechanical Coriolis rate of rotation sensor for detecting rates of rotation with components around measuring axes in three spatial directions which are orthogonal to one another. The Coriolis rate of rotation sensor has a substrate, a detection mass and at least two drive masses, wherein the drive masses can each be driven to perform a primary movement relative to the substrate. The direction of the primary movement of one of the at least two drive masses is perpendicular to the direction of the primary movement of another of the at least two drive masses. The detection mass is coupled to the drive masses. The invention also relates to an Inertial Measurement Unit (IMU) and to a method for detecting rates of rotation in three spatial directions which are orthogonal to one another.

Abstract: A better rate distortion ratio is achieved by making interrelationships between coding parameters of different planes available for exploitation for the aim of redundancy reduction despite the additional overhead resulting from the need to signal the inter-plane prediction information to the decoder. In particular, the decision to use inter plane prediction or not may be performed for a plurality of planes individually. Additionally or alternatively, the decision may be done on a block basis considering one secondary plane.

Abstract: The present invention relates to an arrangement having at least one solar cell, which is formed by a first sequence of differently doped layers (1, 2, 11, 12) on a substrate (6, 16), and at least one bypass diode, which is connected to the solar cell, particularly in a monolithic, series-connected solar module. The arrangement is characterized in that the bypass diode is formed by a second sequence of layers (4, 5, 13, 14), which is arranged between the substrate (6, 16) and the first layer sequence (1, 2, 11, 12). With the proposed arrangement monolithic, series-connected solar modules can be formed at a very low loss of active receiving surface, the solar cells of which are protected by bypass diodes.

Abstract: 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.
