摘要:
A vehicle brake system having a hydraulically actuable disc brake device which has an electromechanical actuating device for activating a parking brake function, wherein the vehicle brake system has a hydraulic circuit with a hydraulic pressure source and actuable hydraulic functional elements, in order to hydraulically actuate the disc brake device in accordance with a service brake action of a driver or an automatic activation of a driving assistance system, wherein, furthermore, the vehicle brake system has a control device, in order to actuate the electromechanical actuating device in accordance with a parking brake action of the driver or an automatic activation of the parking brake function. In order to avoid abrupt release of the parking brake function, it is provided here that the control device is configured for actuating at least one of the hydraulic functional elements in such a way that, in order to release the parking brake function, a hydraulic fluid volume is isolated in the disc brake device by actuation of the electromechanical actuating device and the hydraulic fluid volume can be used to generate a predefined hydraulic pressure hydraulically during the release of the parking brake function by the electromechanical actuating device.

An optofluidic platform is constructed to comprise a vertical integration of optical and fluidic layers. The optical layer enables interaction of light with a fluid for a variety of purposes, including particle detection, manipulation, and analysis. The vertical integration allows layers to be permanently or temporarily attached to each other. Temporary attachments provide the advantage of reusing the same optical layer with different fluidic layers. Most preferably, the optical layer comprises antiresonant reflecting optical waveguide. Further, a fluidic layer can be configured to act as an interface between the optical layer and other fluidic layers attached thereon. Moreover, the fluidic layers can be configured to perform fluidic functions. The optofluidic platform can also comprise a protective layer. As such, a liquid solution can be introduced in the optofluidic platform and single particles contained therein can be optically detected with extremely high sensitivity and without the need for advanced microscopy equipment.

Disclosed is a steam generator pipe which can be produced in a simple and economical manner and which has a particularly good heat transitional behavior having a large band width with various operational conditions. According to the invention, at least one insert is arranged in the inner chamber of the pipe in order to form a swirl-generating inner profile. The insert comprises a plurality of wires which wind, in a screw-like manner, along the inner wall of the pipe in the form of a multi-path thread.

An optical waveguide is provided comprising a non-solid core layer surrounded by a solid-state material, wherein light can be transmitted with low loss through the non-solid core layer. A vapor reservoir is in communication with the optical waveguide. One implementation of the invention employs a monolithically integrated vapor cell, e.g., an alkali vapor cell, using anti-resonant reflecting optical waveguides, or ARROW waveguides, on a substrate.
