Abstract: An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.

Abstract: The disclosure relates to a fluid valve including a lip seal having a sealing lip between a pressure inlet and a pressure outlet, wherein the position of the sealing lip can be varied to vary a passage cross section. The disclosure further relates to a pneumatic valve arrangement having a park release valve and the fluid valve. The disclosure further relates to a pneumatic braking system including the fluid valve or the pneumatic valve arrangement.

Abstract: A method of determining defects in a plurality of images having essentially the same image contents is disclosed. A comparison operation is carried out once three fully comparable images having essentially the same image contents are present in the intermediate memory. The stored individual images are accessed randomly. A paired comparison operation between the three difference images is carried out.

Abstract: A method for measuring overlay shift is disclosed. An image is acquired of at least one reference element that comprises at least one first pattern element in a first plane and at least one second pattern element in a second plane. An image of a measurement element is likewise acquired. The shift value between the reference element and measurement element is ascertained by comparing the image of the reference element with the image of the measurement element. An output on a user interface indicates whether a predefined tolerance value is being exceeded.
