20090076663 | Method and Device for Assigning a Wheel of a Motor Vehicle - A method and device for assigning a vehicle wheel to axles having different wheel sizes. The method includes measuring the acceleration “a” sensed by an acceleration sensor of a wheel electronic system in a wheel. The measured acceleration value is transmitted to an evaluation unit, which compares the measured acceleration value “a” with a standard value stored in a memory for a standard wheel. The evaluation unit assigns the vehicle wheel to an axle as a function of the comparison result. The method and device are particularly suited to determining lift axles for trucks. | 03-19-2009 |

20090119469 | Procedure for Time-Limited Storage of Data on Storage Media - There is described a procedure for temporally limiting the storage of data on storage media, in which the data are provided with an expiry date when being stored on a storage medium. When access is made to these data by a read/write device, the expiry date is compared with a current date. When the expiry date is reached or exceeded, a pre-specified action is initiated—for example the deletion of the data from the storage medium or access being made to the data only by authorization. Based upon the procedure it is possible, on the one hand, to easily render sensitive information such as personal data unusable upon expiration of a storage period, if for example the expiry date is set to coincide with the date when the storage period elapses. On the other hand, copyright and marketing rights for digital data can thereby be easily protected without the additional use of licensing servers of the installation of executable programs. | 05-07-2009 |

The central computer unit determines a safety risk in the safety-critical traffic zone on the basis of the safety-relevant data of all transported hazardous or special material located in the safety-critical traffic zone and sets traffic routing signals. | 12-31-2009 |
