摘要:
The present application relates in a first aspect to a muffler insert for motor vehicles, in particular for passenger cars and motor trucks. This muffler insert in the form of a shaped material made from glass fiber material is in this case present in the form of a wound continuous glass fiber material, the glass fiber material used comprising a textured glass fiber. In a further aspect, the application is aimed at a method for producing such a muffler insert, a glass fiber material being wound as continuous glass fiber, which is a textured glass fiber, around a carrier in order to form a shaped material, and this shaped material being used as a muffler insert, if appropriate after further processing steps.

A first aspect of the present application relates to a method for producing sound-damping, sound-absorbing and/or insulating molded material. More specifically, the method according to the invention relates to a method for producing said molded materials, wherein the fibrous material is wound around at least two carriers and subsequently the wound blank thus obtained remains on the carriers so as to be permanently solidified in order to obtain the molded material according to the invention. A further aspect of the present application concerns the molded material thus obtained, in particular in the form of molded mats or molded objects. Said molded material can be used, in particular, in mufflers. Finally, the following application concerns a device for producing said molded materials from fibrous material.

A band-stop filter is proposed which is constructed on a multilayered substrate and consists of a parallel circuit comprising a bandpass filter and a high-pass filter. The two filters are at least partly realized in the form of LC-elements integrated into the substrate. Further circuit components can be arranged as discrete components on the substrate. In the filter branch having the bandpass filter, an electroacoustic resonator is arranged in a transverse branch to ground. By means of the filter, a wide stop band is obtained, while the passband or passbands can comprise a plurality of radio bands.

An electromechanically actuable parking brake for motor vehicles is disclosed. The brake includes at least one electromechanical actuator whose rotational movement is converted into a translational movement by an actuating unit, and which moves at least one brake element in such a way that at least one brake lining which is connected to the brake element is pressed with a locking force against a rotor which is connected to a motor vehicle wheel, wherein the current consumption of electromechanical actuator when the parking brake is engaged and/or released can be acquired. Furthermore, a method for operating the electromechanically actuable parking brake is also disclosed.

摘要:
A control unit determines whether an accident of a motorcycle has occurred in that corresponding measurement data from a sensor system are analyzed. Following this, a fully automatic emergency call is emitted. The emergency call is transmitted via a voice channel after the emergency call data have been subjected to a media conversion.

The present invention relates to an assembly (10) comprising at least a first stent (1′) and a second stent (1′). Each stent comprises a proximal section (2), a central section (3), and a distal section (4). The proximal and distal sections provide a radial force which is essentially equal to a half of the radial force which is provided by the central section. Thus, by overlapping the distal section (4′) of the second stent (1′) to the proximal section (2′) of the first stent (1′), the radial force which is provided by the overlapped sections is nearly equal to the radial force which is provided by the central sections (3′, 3′) of the two stents.
