Abstract: An under sleeper pad (1) for fastening to an outer surface (2) facing a ballast bed (16), in particular an underside, of a railroad sleeper (3). The under sleeper pad (1) includes an elastomer layer (5), the elastomer layer (5) having a density in the range of 250 kg/m3 to 350 kg/m3, preferably 250 kg/m3 to 330 kg/m3.

Abstract: The invention concerns a method for establishing a telecommunication connection between a calling subscriber (1) and a target subscriber (5), in which a calling terminal (R) of the calling subscriber (1) and a target terminal (Z) of the target subscriber (5) are assigned to a switching unit (100) and the calling subscriber (1) enters a callback request (CCBS-REQ, CCNR-REQ) in the switching unit (100) if the target terminal (Z) is busy or cannot be reached when a first call is made from the calling terminal (R) to the target terminal (Z), in which configuration data regarding the accessibility of the target subscriber (5) for a callback are entered into the switching unit (100).

Abstract: The invention relates to a conferencing unit for multi-point communication in the course of a telephone conference. Previously, it was not possible to call up and document agreements and decisions in voice-based telephone conferences in a computer-aided manner. The reason was that in traditional conferencing units, all audio channels were mixed into an overall channel and therefore an undisturbed interaction of individual participants with the system is not possible. The invention enables an individual association of a conference participant with a decision processing unit, in which decisions can be announced in a dialog system and stored in a computer-readable format.

Abstract: A user is provided with an analytical function which indicates an individual contribution of each search term used in a complex search query by a graphical, typographical or numerical indicator. For this purpose there is started in the background for each search term a search query which consists of the complex search query without the respective search term. The hit count obtained in this way is subtracted from the total hit count of the search query with the respective search term. The difference is a numerical indicator for the individual contribution of the respective search term to the total hit count. Thus, the user quickly and conveniently obtains a reference point indicating which search terms are crucial to the search query. The user can thus selectively refine the search query by explicitly specifying less significant search terms or removing overly restrictive search terms.
