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.

For improving the matching of a DMS track that is connected in series with a reactance element, it is proposed to connect a shunt branch to ground between the DMS track and reactance element parallel to the signal-carrying conductor section, where a capacitive element is arranged in this shunt branch.
摘要:
A system and a method of transmitting data via data networks. A bidirectional data connection is created even behind firewalls, including from a client not visible to a server in the Internet. In the method and system, a first connection request for establishing a first transmission channel is sent to a server of an automation system from a first data processing device of a client via a data connection. This request is answered by the server via a second transmission channel. The data connection is kept permanently open, thereby allowing mutually time-independent bidirectional sending and receiving of data between the client and the server, via at least one data network. A COM automatic marshaller which incorporates itself into the communications chain between the client and the server is provided.

A hydraulic vehicle brake equipped with a parking brake device, in particular for motor vehicles, including a brake housing in which a hydraulic service pressure chamber is delimited by a brake piston, wherein the parking brake device acts on the brake piston and, in the applied condition, can be locked by a locking device, and an energy accumulator cooperating with the brake piston is equipped with at least one integrated spring element. In order to realize a simple and low-cost parking brake function that complies with legal requirements, according to the invention, the parking brake device is operable by a pressure that is introduced into the service pressure chamber and enables charging the energy accumulator.

A surface acoustic wave filter includes an acoustic track bounded by reflectors, at least a first input transducer and at least a second input transducer acoustically coupled to the acoustic track that are connected in parallel and connected to an asymmetric input port, at least two first output transducers acoustically coupled to the acoustic track that are connected in parallel and connected to a first terminal of a symmetric output port, and at least two second output transducers acoustically coupled to the acoustic track that are connected in parallel and connected to a second terminal of a symmetric output. Each first output transducer in the acoustic track and corresponding second output transducers are side-by-side and are electrically connected in series via a first bus bar.

A component (10) for vehicle interiors comprising a first fixed assembly (12) that can be mounted on the wall (18) of the vehicle interior and a second assembly (14) that is displaceably attached to the first assembly (12), the second assembly (14) being displaceable in opposition to the action of elastic elements (20) from a resting position into a position of use and vice versa and the second assembly (14) being displaced from the position of use into the resting position, or being maintained in the resting position by the sole action of the elastic elements (20), has the distinguishing feature that the elastic elements (20) take the form of at least one elastically extensible strap or cable or an elastically extensible cord.
摘要:
For improved conformance of a filter operating with acoustic waves, a transducer structure is provided in which the separations between respectively two adjacent electrode fingers of an inter-digital transducer (IDTv) vary over the length of the transducer. The variation thereby preferably follows a continuous distribution function. Reactance filters that are provided with such filters in the serial branch show an improved electrical conformance in the transmission range.

A method for preparing a transmission electron microscopy (TEM) sample for electron holography includes forming a sacrificial material over an area of interest on the sample, and polishing the sample to a desired thickness, wherein the area of interest is protected from rounding during the polishing. The sacrificial material is removed from the sample following the polishing.
