Abstract: A method for detecting a wear-relevant load on a vehicle wheel uses a tire pressure monitoring unit mounted on the vehicle wheel containing an acceleration sensor. A rotational frequency of the vehicle wheel is determined for a time interval from a series of measured values of the acceleration sensor at first time intervals. A centrifugal acceleration value is determined for the time interval. A proportionality factor is determined from the rotational frequency and centrifugal acceleration value, linking the square of the rotational frequency with the centrifugal acceleration. A rotational frequency of the wheel is continuously calculated from measured values of the centrifugal acceleration, which have been determined at second time intervals that are greater than the first time intervals, and from the proportionality factor. A load value is respectively calculated from the rotational frequency and the second time intervals. These load values are continuously added up to an overall load.

Abstract: A system and method for the real-user capable monitoring of the rendering process of dynamically updated web pages is presented. The proposed approach deploys a browser agent to content loaded and displayed by a web browser which monitors resource load activities caused by the processing of the content by the browser and in-place content modifications caused by the executions of scripts and XHR communication by the browser. Those resource load and content modification activities affecting the visible area of the browser are identified and a point in time is calculated at which the visualization of the content for the visible area is complete. Further performance monitoring data describing the performance of the rendering process depending on the percentage of finished portions of the visible area over time is calculated. In addition, data describing the rendering process in detail may be captured by the browser agent which may be used for a later playback of the rendering process.

Abstract: A tire pressure monitoring unit is mounted on a vehicle wheel having a pressure and acceleration sensor. A method for assigning wheel positions includes pressure and acceleration data determined from the sensors. The pressure data and at least one piece of information derived from the acceleration data are transmitted wirelessly in a data telegram together with a characteristic identifier. Information concerning the reliability of the information derived from the acceleration data is acquired in the tire pressure monitoring unit on the basis of the measurements and is transmitted with the data telegram. A central evaluation unit considers a plurality of data telegrams and, taking account of data from the ABS sensors, assigns the individual tire pressure monitoring units to wheel positions. Data telegrams in which the reliability is higher receive a greater weighting, and data telegrams in which the reliability is smaller receive a smaller weighting.
