The invention describes a methods of enabling and performing location-based services especially geomessaging. The invention describes in detail a flexible combination of multicast Internet protocol addresses and area codes in order to generate geomessaging Internet protocol addresses. The geomessaging Internet protocol address enables to receive by means of a mobile communication device () according to the invention geomessages and to submit the geomessages by means of the geomessaging network entity () according to the invention. No signaling between the mobile communication device () and the network or any service provider within the network is necessary to specify the current location of the mobile communication device. Furthermore, there is no need for a geomessaging message provider to know which mobile communication device is currently located within a specific first area.

IP multicast for geomessaging

A mathematical scattered radiation model with a number of parameters is specified. A test object is scanned with an X-ray system to generate a first raw dataset. The test object is scanned again to generate a second raw dataset, this time with an intermediary X-ray mask having at least one X-ray transparent region and at least one X-ray non-transparent region between the X-ray source and the test object. Parameter values are determined based on the first raw dataset and on the second raw dataset, and the scattered radiation model is calibrated with the parameter values. An examination object is scanned with the X-ray system to generate a third raw dataset and the third raw dataset is processed with the calibrated scattered radiation model to generate a corrected third raw dataset. A set of X-ray image data is generated from the examination object based on the corrected third raw dataset.

The present invention relates to a computing arrangement (), said computing arrangement () comprising a computer device (), multiple input- and/or output-devices () attached to said computer device (). In order to allow the parallel usage of multiple input- and/or output-devices which are attached to a computer device as peripheral devices, the computing arrangement () is characterized by a control device () for associating said multiple input- and/or output devices () to at least two different GUI (Graphical User Interface) instances.

A method as well as a system are described for determining the travel time of at least one mobile user end device between a starting point (A) and an end point (E) that is spatially separated from it. To this end, specific pieces of information of at least one mobile user end device located at the starting point (A) and at the end point (E) are determined and each linked to a time marker. The specific pieces of information of the mobile user end devices are compared with one another electronically in at least one central processing unit. When the specific pieces of information of a mobile user end device are in agreement at the starting point (A) as well as at the end point (E), the time difference between the time markers is formed electronically in the central processing unit and the travel times are determined therefrom. The method can be carried out advantageously by the use of a cellular mobile wireless system (), wherein the starting point (A) and the end point (E) are each formed by corresponding cells () of the mobile wireless system (). The determination of the travel time results from the data of the mobile wireless system ().
