Abstract: A control device and a corresponding control method are provided for establishing an information-output ranking of a plurality of information sources, in particular audio sources. In order to output the information of the information sources to a common information-output device, the information-output ranking is established in pairs for the audio sources which is in the form of an audio-output matrix having a nonlinear order with respect to the matrix elements, and wherein each matrix element of the information-output matrix is used to determine the priority of a corresponding information source with respect to another information source. A conflict among competing information outputs is solved in this manner.

Abstract: Networked vehicle communications system with front end unit, terminal which can be operated by a user and associated application. A vehicle communications system having a databus and at least one front end unit which is connected thereto and has a user-interface framework unit, having at least one terminal which can be operated by the user and is connected to the databus, and having at least one functionality which is implemented in the system and can be executed with the participation of the front end unit and of the terminal. The implemented functionality is divided into a part which communicates with the user-interface framework unit and has user-interface ends and into a functional component part which communicates with the user-interface end part on the one hand and with an application framework unit on the other.

Abstract: Described is an arrangement for securing a water-impervious flexible web (10) comprising an elastomer on a walling means (6) to be sealed, in particular a flat roof, having a holder member (1) which can be secured to the walling means (6) and which has a projection (5) with an outwardly projecting side bead (7) forming an undercut configuration (8), and an outer securing member (11), with the web (10) being arranged to be clamped between the holder member (1) and the outer securing member (11).
