20080309325 | Method and Device for the Determination of the Road Clearance of a Vehicle - In a method for determining road clearance of a vehicle, the vehicle is moved relative to a measurement configuration with a reference surface. One or more magnets, which are disposed on the vehicle and assigned preferably each to a defined measurement point on the vehicle, is detected by at least one device for magnetic field measurement. With the help of at least one device for separation measurement, the separation between the measurement configuration and the bottom side of the vehicle is determined. In this way, a rapid, reliable, repeatable and flexibly usable method for the determination of the road clearance of a vehicle is provided. A corresponding device is provided for implementing the method. | 12-18-2008 |

20120178413 | Technique for Monitoring a Call - A technique for monitoring a call associated with a connection established via a Media Gateway node (MGW) is described. The Media Gateway node (MGW) is controlled by a Media Gateway Controller node (MGC). The Media Gateway node (MGW) and the Media Gateway Controller node (MGC) belong to a layered network (LN). A method implementation of this technique comprises the steps of detecting a loss of communication between the Media Gateway Controller node (MGC) and the Media Gateway node (MGW) and logging the loss of communication together with a time stamp of the detected communication loss to be used for determining a charging time of the call. | 07-12-2012 |
