Abstract: A method determines translational and/or rotational deviations between the measurement coordinate system of a measurement mirror scanner and the processing coordinate system of a processing mirror scanner. A measurement beam reflected at a workpiece returns on a path of an incident measurement beam and is captured by a spatially resolving measurement sensor to ascertain spatially resolving information of the workpiece. The reflected measurement beam, in a sensor image of the measurement sensor, is imaged onto a previously known image position. This is accomplished by ascertaining a focal position deviation of the processing beam by scanning with the processing beam, evaluating a laser power detected at grid points, fixing the processing mirror scanner, capturing spatially resolving height information of the pinhole diaphragm by the measurement sensor, and determining a translational deviation between the processing and measurement coordinate systems based on the deviation.

The first angular surface (302) and the second angular surface (304) are provided at a first angle (?) and a second angle (?) with a central axis (A-A?) of the nut body (110).

Abstract: A device and method for steering a laser beam to a focal point in target tissue requires generating a laser beam. Diversions of the laser beam from a central beam path are minimized by a sequential arrangement of optical steering components. In order, the beam is first directed to the center of a z-scanning apparatus which will move the focal point in the medium in a z-direction. The beam is then passed to the center of a first galvanometric mirror which introduces focal point movements in the x-direction. A second galvanometric mirror then compensates for the x-direction movement by redirecting the beam to the center of a third galvanometric mirror where focal point movements in the y-direction are introduced.

Abstract: A method is disclosed for photodisrupting a surface in the stroma of an eye at a substantially constant distance from the anterior surface of the eye. A frame of reference is established for the eye that includes an axis of rotation. Next, the focal point of a laser beam is positioned in the stroma at a radial distance from the axis. At least one laser pulse is delivered to the stromal tissue at the focal point, photodisrupting the tissue there and creating a photodisruption bubble having a diameter “d”. The focal point is then rotated about the axis through an arc length substantially equal to “d” and the photodisruption step is repeated. During rotation, the distance between the focal point and the axis is decreased at a rate substantially equal to the distance “d” per revolution. The method can be used to create a flap for a LASIK type procedure.

Abstract: An engine drag-torque control, particularly for motor vehicles, in which the engine torque is increased by an EDC augmenting torque when the driven wheels drop below a slip threshold due to the braking action of the engine and exhibit a brake slip which is too high. To improve the vehicle control during cornering on a roadway having a low coefficient of friction, it is provided to increase the slip threshold for the driven wheels to thereby set the drag-torque control to be more sensitive.
