Abstract: The present invention relates to an armature spring (4) for a relay comprising a fastening section (3), a connected oblong spring section and a lever (7). The lever is located on the side of the longitudinal axis of the spring section opposite to that of the fastening section (3) so that the spring section is subject to torsional stress. Due to the torsional stress of the spring section, an even progression of the spring characteristic curve can be achieved. The stress is very even, so that the spring is very small and simple. In advantageous embodiments, the spring section extends parallel to the armature pivot axis and is formed by a torsion web (6). The lever section can be flexibly deformable. As a result the spring characteristic can be particularly easily and flexibly adjusted. As a result the spring armature can be combined with a magnet system exhibiting opening angles of 10° to 15°.

Abstract: The magnet system is part of a relay, which displays particularly low-noise switching. Components of the magnet system include a core unit (1), an armature (6) and a not represented coil, whereby the armature (6) is preloaded in an open position. The low-noise switching behavior is achieved in that the armature (6) is designed in such a manner that the armature pole face in the region of its front end (8a) in the closing direction is essentially perpendicular to a connecting line (16) towards the bearing edge (12). In addition, when the armature (6) is attracted, the core pole face (9) extends at least substantially parallel to the armature pole face (8). The arrangement according to the invention requires no additional parts for the purpose of noise reduction, resulting in a particularly simple and compact structure.

Abstract: The invention relates to methods for the qualitative and quantitative determination of differentially expressed mRNA molecules. Said methods are used especially to determine all possible mRNA molecules present in a cell or a tissue, and to compare them with other cells or tissues, with other conditions (stages of disease or development), or with stages of treatment for these conditions. The method provided for in the invention therefore makes it possible, for example, to establish a comprehensive map of the different mRNA molecules present in a defined mRNA population and subsequently to use the preferably digital information obtained in this way in data base analyses.

Abstract: In a method and systems for selecting traffic information services that are receivable by at least one mobile receiver and are relevant for a route previously determined by a navigational device linked to at least one receiver, service information, which identifies the services having traffic messages relevant for the route, is read out from a stored list for the determined route. In the case of a plurality of services, a table is created that includes the read-out service information, which is sorted according to a valuation and is able to be modified as the route is followed. A receiver is set, in each case, to the highest-rated service.

Abstract: The relay comprises a base body (27), a coil (1), a core arrangement (3), an armature (10) and a contact system. The contact spring (16) is configured as an arc and arranged to be connected with the armature (10) in such a way that it is subjected to uniform, low mechanical loading. As a result a material can be used for the contact spring (16) which presents high electrical conductivity, so that the forward resistance of the relay is reduced. The contact spring (16) and armature (10) are arranged in such a way that a relay with a compact structure can be obtained.

Abstract: A navigation method is set forth for calculating a travel route of a vehicle from a starting or an actual vehicle location to an operator-defined destination and for guiding a vehicle operator during operation of the vehicle over and along the calculated travel route, in which at least one possible parking location at the operator-defined destination is designated and the at least one possible parking location is included in the calculating of the travel route as a location to which the vehicle is guided when the operator conducts the vehicle over the travel route. After input of the operator-defined destination into a navigation unit of the vehicle by the operator, the location to which the vehicle is guided over the travel route is determined by the navigation system advantageously automatically taking account of the available parking locations at the input destination.

Abstract: The relay has, one after the other on an elongate, narrow base body, a magnetic system and a contact arrangement having at least one fixed contact carrier and at least one movable contact spring. The contact carriers are in this case each embedded by a middle section into the plastic of a base body in such a way that their connecting lugs lie in a plane parallel to the longitudinal axis of the relay, while their contact-making end sections, which emerge on the upper side of the base body, lie in planes which are parallel to one another and perpendicular to the plane of the connecting lugs. This enables dimensionally accurate embedding of the contact carriers with good insulation with respect to the magnetic system and with easy processing from a sheet-metal plate.
