The invention relates to a method and an x-ray examination unit for analyzing and representing x-ray projection images with an x-ray examination unit, where the function relation b=&#x192;(J/J) is established between the attenuation value and a material-equivalent value as a function of the energy spectrum used, and for the purposes of projection representation, the magnitude of the material-equivalent value bof a specific material is represented as an image value.

A method for ascertaining a billing tariff for billing for a data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves setup of a data tunnel, used for transferring the data, prompting transfer of an item of location information which relates to the communication terminal from a switching center, temporarily associated with the communication terminal, in the visitor mobile radio network to the network gateway node in the data mobile radio network. The network gateway node transfers the item of location information to a billing system, and the billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network. Thereupon and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

Method for ascertaining a billing tariff for billing for a data transfer

A method for ascertaining a billing tariff for billing for a packet switched data transfer, where a mobile communication terminal which is involved in the data transfer and has access rights for a data mobile radio network is situated in a visitor mobile radio network. The method involves a data link being set up between a billing system, which performs billing for the data transfer, and a central subscriber register in the data mobile radio network, and this data link being used to transfer to the billing system an item of location information which relates to the current location of the communication terminal. The billing system uses the item of location information to establish that the communication terminal is situated in the visitor mobile radio network, and the billing system ascertains a billing tariff which is associated with the visitor mobile radio network.

The invention relates to a method for operating a billing system for billing for services provided by a service provider and/or for transmissions of service data via a terminal used by a subscriber using a communication network, where the service provider is arranged outside the communication network, and the billing system accesses subscriber profile data stored in a home location register in the communication network. Access to the subscriber profile data is followed by use thereof to ascertain the TCP/IP address of an account server which manages an electronic credit belonging to the subscriber. The invention also shows a billing system for carrying out the method.

Linear fluorooligomers having at least two reactive end groups per polymer molecule are incorporated into radiation sensitive polymer systems which have improved continuous temperature resistance and low dielectric constant. The polymer systems can be applied as lacquers. Preferably perfluorated poly-ethers and perfluorated alkanes are used as starting compounds. The polymeric product is usable as a coating for the production of printed multi-layer wirings and economises on through-bores and additional copper intermediate layers. A further field of application exists in the field of integrated semiconductor circuits in VLSI-technology for the production of negative photo-resists.
