Abstract: A method for operating a steering apparatus of a motor vehicle includes detecting interference-induced vibrations which act on a torsion bar of the steering apparatus and analyzing a frequency and amplitude of the interference-induced vibrations. A steering-stabilization function of the steering-assistance device is activated when a limit value for the amplitude of the interference-induced vibrations is exceeded. A drive signal is provided, with the steering stabilization function, for an electric motor of the steering-assistance device, so that the electric motor generates a compensation torque Mbar which acts on the torsion bar and at least partially counteracts the interference-induced vibrations. An indicator is formed from the frequency and the amplitude of the interference-induced vibrations and the carriageway induced vibrations are distinguished from vibrations caused by instabilities in the steering apparatus.

Abstract: A ring-shaped metal rolling bearing cage, which has cage pockets for receiving rolling elements. The cage is formed by a first and a second cage segment. Adjoining ends of the cage segments are connected to one another by suitable connection assemblies. At least one of the assemblies permits a change of the cage diameter when the cage temperature changes. The suitable assembly, on one side, is configured as a joint mechanism and, on another side, as a locking mechanism, and at least one of the assemblies has a lash. A rolling bearing cage configured with the joint mechanism and the locking mechanism can be mounted with low time expenditure in a simple and reliable manner over a shaft, particularly in the case of an idler pinion mourning.

Abstract: For testing a transformer (20) the transformer (20) is emulated by an equivalent circuit (30) and an accuracy of the transformer (20) relative to the equivalent circuit (30) is determined by evaluating a test response of the transformer (20) and is then automatically converted to an operating condition-related accuracy of the transformer (20).

Abstract: This invention relates to methods and an apparatus for detecting quality induced terminations of media streams of real-time communication sessions within a packet-switched network. To enable the determination of the quality of live media streams passing by the tapping points in a network, and to use this information to determine media transmissions being aborted due to bad quality the invention evaluates quality data records of a terminated media stream to detect, whether the media stream was terminated due to bad quality or another reason. Advantageously, a threshold number of quality data records that were generated for the media stream just before termination thereof are considered in the evaluation. In case each of this threshold number of quality data records yields a bad quality of the media stream, the termination of the media stream may be judged or assumed to be induced due to bad quality.

The rolling bearing cage includes fewer rolling elements in the at least one row than the number of rolling element pockets, such that the at least one empty pocket does not receive a rolling element. A method for producing a rolling bearing cage is also provided.

Abstract: In order to effectively protect a particle measuring device (8) against temperatures that are too high and/or too low, it is provided that the temperature (T) of the sample gas is measured upstream of a first temperature-sensitive sample gas processing or sample gas measuring device (20, 21, 22, 42) in the particle measuring device (8) and that the measured temperature (T) is compared with a first and/or second limit value (To, Tu) and that the particle measuring device (8) is switched into a safe mode if the measured temperature (T) exceeds the first limit value (To) or falls below the second limit value (Tu).

Abstract: The invention relates to methods and systems for detecting periodic impairments of media streams of real-time communication sessions within a packet-switched network. The invention is performed in a passive monitoring system monitoring a plurality of media streams providing quality data records for each monitored media stream and for predefined time intervals. For each media stream a frequency distribution is generated, which is indicative of the number of good quality data records between two quality data records indicative of impairment. If a maximum exists in the media stream's frequency distribution for a given number of consecutive good quality data records, the stream is determined to be periodically impaired and said given number of consecutive good quality data records for which the maximum exists indicates the periodicity in the impairment of the media stream.

Abstract: This invention relates to methods for correlating at least one media path and a signaling session of a packet-switched network and to an implementation of these methods in hardware and software. To overcoming one or more of the limitations and challenges on the correlation of signaling plane and media plane of services, the invention defines a key, which can be used for correlation of media streams and signaling sessions. The invention is based on a signaling probe identifying new services and associated media paths of the media plane by detecting their corresponding signaling sessions and determining for each service a signaling session identifier. The signaling probe registers the signaling sessions and their media paths at a correlation unit using the signaling session identifiers as a key, which allows a media probe to query the correlation unit for respective signaling session identifiers that correspond to media paths detected in the media plane traffic.

Abstract: A medicine dispensation device, in particular a multi-dose powder inhalator, for the dispensing of individual doses of medicine that has a number of medicine chambers contained in a medicine magazine shaped like a continuous loop. The medicine chambers form groups in such a manner that a mouthpiece reaches the different groups by an essentially complete rotation of the medicine magazine. This enables several medicine chambers—typically one, two or three—to be situated between two successive intake positions, which allows for a high density of medicine chambers and thus creates an inhalation device, which can be handled comfortably even when containing a great number of individual doses.
