Abstract: The invention provides a rotation transformer for a cable connection including separation discs rotatable about a longitudinal axis. In use, one end of a cable executes a limited number of revolutions about the longitudinal axis in relation to the other end while maintaining an uninterrupted connection between the two ends. The distance between the rotatable separation discs is measured such that a maximum of two coils of the cable lie on one plane between two separation discs. The cable is guided through the discs without converging and is wound alternately from the outer diameter of a disc to the longitudinal axis and vice versa between the pairs of separation discs.

This coupling device is characterised in that the outer part and the inner part can move relative to one another and in the longitudinal direction of the retaining device between a locking position and a release position, wherein at least one wedge surface, arranged sloping with respect to the longitudinal axis of the retaining device, is provided on the outer part, which interacts with at least one complementarily formed wedge surface, which is provided on the inner part.

Abstract: The invention relates to a rotation transformer for a cable connection, one end of said cable (4) executing a limited number of revolutions in relation to the other end, about a longitudinal axis (1), whilst maintaining an uninterrupted connection between both ends. The longitudinal axis (1) comprises separation discs (3). Known rotation transformers of this type have an extremely complex technical construction. The aim of the invention is to configure a rotation transformer in such a way that it can be produced simply and cost-effectively. To achieve this, the distance between the rotatable separation discs (3) is measured in such a way that a maximum two coils of the cable (4) lie on only one plane between two separation discs (3), that the cable (4) is guided through said discs without converging and that it is fixed and wound alternately from the outer diameter to the longitudinal axis (1) and vice versa between the pairs of separation discs (3).

Abstract: The invention relates to a method for the optimized assignment of access rights to IT resources managed by means of a security management system and to a correspondingly adapted security management system. According to the invention a security domain is defined on the basis of at least one attribute of IT resources and a plurality of authorization profiles is provided for the security domain. User groups are assigned to the domain and linked to profiles provided for the domain. IT resources for which the security management is responsible are allocated to the domain in accordance with the attribute defining the security domain, as a result of which user groups assigned to the domain receive access rights to the IT resources allocated to the domain in accordance with the profiles linked to them. The invention permits the user groups to be issued with authorizations that are tailored to the requirements of the individual groups.

Abstract: The invention creates a technology for validating simulation results. The quickly growing number of components in modern complex systems often necessitates the introduction of abstractions, that render said systems manageable. However the abstractions, which often are based simplified assumptions, may impair the simulation results. The automatic post-processing method according to the invention safeguards the validity of the result. In most cases this can be reached, without restoring the complete description, which generally is too complex. The method, which is described for the validation of calculated counter-examples in an equivalence comparison of digital circuits can be used in all other applications, that allow for an analagous formalization of the abstraction step.

Abstract: Assignment information items for assigning signal-path identifiers of circuit descriptions in accordance with a second description format also as a function of the circuit description in accordance with a first description format, from which circuit description the circuit descriptions in accordance with the second description format have been produced by conversion. The circuit descriptions in accordance with the second description format are generated from the circuit description in accordance with the first description format in such a way that the information content is not smaller in regard to the signal-path identifiers, with the result that the assignment of the signal-path identifiers in an equivalence comparison is facilitated.
