Abstract: A method for determining an angle of rotation between a sensor array and a magnetic field of a magnet, whereby the magnetic field is formed substantially parallel and perpendicular to the rotation axis, and the magnet is arranged rotationally symmetric relative to the rotation axis. A first measurement signal and a second measurement signal are generated by the two subsensors of the first magnetic field sensor unit, and the first measurement signal is assigned a first relation and the second measurement signal is assigned a second relation. A third measurement signal and a fourth measurement signal are generated by the two subsensors of the second magnetic field sensor unit, whereby the third measurement signal is assigned a third relation and the fourth measurement signal is assigned a fourth relation. The angle of rotation is then determined.

Abstract: A method for monitoring the function of a sensor module including sensor which generates a measurement signal for a physical quantity to be determined and applies the measurement signal to an output terminal in an unchanged form or in processed form. In addition, a test signal is generated whose spectrum lies outside the spectrum of the measurement signal. The test signal is supplied at a place in the sensor from which it reaches the output terminal in unchanged form or in processed form only in the case of a functional sensor. An output signal present at the output terminal is compared with the test signal and a diagnosis signal is generated, which indicates whether the test signal is present at the output terminal. The test signal is filtered out of the output signal and the remaining signal is applied as the measurement signal at an output of the sensor module.

Abstract: The invention relates to an integrated circuit arrangement with connection contacts for the serial exchange of data and/or signals with external components and apparatuses and with a control apparatus and/or a serial interface for the clocked receiving of data by means of a signal voltage on such a connection contact, which voltage is modulated between at least one low, one middle and one high voltage state. The control apparatus and/or the interface are designed in such a manner that data is sent in a sending mode via the connection contact in that the switching apparatus, after having received a slope changing in particular from the middle voltage state into in particular the higher or the lower voltage state, pulls the voltage state into the in particular opposite lower or higher voltage state. Furthermore, the invention relates to an apparatus and a process for operating such a circuit arrangement.

Abstract: In a method for monitoring the function of a sensor module, which has a sensor, by means of the sensor a measurement signal for a physical quantity to be determined is generated and applied to an output terminal in an unchanged form or in processed form—after at least one linear signal processing step and/or at least one nonlinear signal processing step are performed. In addition, a test signal is generated whose spectrum lies substantially outside the spectrum of the measurement signal. The test signal is supplied at a place in the sensor from which it reaches the output terminal in unchanged form or in processed form—after the performance of the at least one linear signal processing step—only in the case of a functional sensor. An output signal present at the output terminal is compared with the test signal and a diagnosis signal is generated, which indicates whether the test signal is present at the output terminal.

Abstract: A playback apparatus includes a data source (1) that provides a data stream signal (d0), and a device (2) responsive to the data stream signal. The device forms a first data stream (d1) in a first data format (F1), wherein the first data stream (d1) includes a data field (D1) that is encoded in a second data format (F2). A code converter (3) is responsive to the first data stream (d1), and converts selected parts of the first data stream (d1) to a second data stream (d2) that has data encoded in a third data format (F3). An output decoder (5) forms playback signals from the second data stream (d2). The playback signal may be audio and/or video signals that are presented to the appropriate audio transducer or display device for presentation to a playback apparatus user(s).

Abstract: The invention relates to operating a stand-alone, in particular, portable video and/or audio reproduction device (MP3) as an external device (MP3) on an audio system (M), in which audio data (d) are supplied in the external device (MP3), the external device (MP3) is controllable so as to transmit audio data (d) through an interface (B) to the audio system (M), and the audio system (M) is designed and controlled in order to process and/or reproduce audio data (d), wherein control of the external device (MP3) is effected through the audio system. Analogously, the invention relates to an audio system, or to an integrated consumer video and/or audio circuit (IC) for this type of audio system, to control a stand-alone external audio reproduction device (MP3) by means of control signals from the audio system or consumer video and/or audio circuit.

Abstract: Method and apparatus for active noise suppression in stereo multiplex signals particularly in an automotive radio receiver includes an insertion circuit where the disturbed signal section is replaced with an insertion signal formed by sampled signal values/signal sections which are located before and/or after the disturbed signal section. Basic-delay stages ensure that only those sample values are used for the insertion signal which are separated from the respective instant of insertion by a time interval having an integral relationship nT to the period T of a carrier contained in the stereo multiplex signal (where n is a positive integer).
