Abstract: The present disclosure demonstrates a method for predicting the risk of stroke of a subject and a method for improving the prediction accuracy of a clinical stroke risk score. The methods are based on the determination of the amount of Angiopoietin-2 (Ang-2) and/or the amount of Insulin-like growth factor-binding protein 7 (IGFBP7) in a sample from a subject. Moreover, disclose is the use of i) the biomarker Ang-2 and/or the biomarker IGFBP7, and/or ii) at least one detection agent that specifically binds to Ang-2 and/or at least one detection agent that specifically binds to IGFBP7 in a sample from a subject for predicting the risk of stroke of said subject.

Abstract: An electronically slip-controllable power braking system for a motor vehicle, in which a controllably drivable pressure generator supplies multiple brake circuits connected in parallel to one another with pressure medium under brake pressure. Each of the brake circuits are separable through existing first control valves from the pressure generator and include second control valves that are connected downstream from the first control valves to control the brake pressure in the wheel brakes, which are connected with the brake circuits. An electronic control unit in the brake circuits has three devices, the third device puts the first control valve of a brake circuit into a passage position if a leakage is established downstream from the second control valve in this brake circuit and if it is established that the pressure generated by the pressure generator has at least approximately reached or exceeded a pressure limit of the first control valve.

Abstract: A method for functional testing of an electromechanical fill level monitoring device. In order to test the plausibility of a signal emitted by a fill level monitoring device of a first pressure medium chamber, a forced actuation of this fill level monitoring device is carried from time to time. This forced actuation is carried out in that a pressure medium delivery unit in a pressure medium circuit having the first pressure medium chamber is activated for a predefined period. This delivers the pressure medium fill level monitoring device into a second pressure medium chamber via a pressure medium connection. On the basis of the signal profile output by the fill level monitoring device, the proper operation of the fill level monitoring device is inferred in the electronic control unit.

Abstract: For testing the functional capability of a hydraulic power vehicle braking system, a power brake pressure generator is switched on. The power brake pressure generator displaces brake fluid through the non-actuated master brake cylinder into a brake fluid reservoir, which is why no brake pressure is built up. A brake pressure build-up allows a “hidden defect” to be inferred, which has no impact during normal operation and is therefore not noticed.

Abstract: To prevent the loss of any brake fluid from a hydraulic vehicle braking system after a detected leakage, a testing or a re-testing of a leak tightness of the vehicle braking system is carried out only after release, for example, after a repair of the vehicle braking system.

Abstract: To test a vehicle power braking system, a piston of a power brake pressure generator is displaced twice for a pressure build-up and in between back preferably by a longer distance. Extension of the piston travel during the second displacement is an indication of air in a cylinder of the power brake pressure generator due to an excessively low brake fluid level in a brake fluid reservoir.
