摘要:
A machine part is guided along a defined movement path over a workpiece surface. The machine part is held at a defined distance from the workpiece surface during this movement. For that purpose, at least one distance sensor is provided that runs ahead of the machine part with a defined lead. A plurality of distance values indicative of a distance between the distance sensor and the workpiece surface are determined along the movement path. A plurality of control values are determined as a function of the distance values. The defined distance is repeatedly adjusted by means of the control values. In accordance with a first aspect, the distance values are determined at measurement points distributed with a first grid spacing along the movement path, while the control values are determined for actuating points distributed with a second grid spacing along the movement path, the first and the second grid spacings being different. According to a second aspect, the machine part has a linear range of activity on the workpiece surface, and the distance between the machine part and the workpiece surface is controlled by means of a distance control value and an angle control value, which are derived from distance values acquired from at least two distance sensors, which are laterally offset from one another.
摘要:
Systems and methods are disclosed for focusing a beam for an interaction with a film deposited on a substrate wherein the focused beam defines a short axis and a long axis. In one aspect, the system may include a detecting system to analyze light reflected from the film on an image plane to determine whether the beam is focused in the short axis at the film. In still another aspect, a system may be provided for positioning a film (having an imperfect, non-planar surface) for interaction with a shaped line beam.

A machine part (12) is guided along a defined movement path (28) over a workpiece surface (23). The machine part (12) is held at a defined distance (50) from the workpiece surface (23) during this movement. For that purpose, a distance sensor (14) is provided that runs ahead of the machine part (12) with a defined lead (18). A plurality of distance values between the distance sensor (14) and the workpiece surface (23) are determined. A plurality of control values for adjusting the defined distance (50) are determined as a function of the distance values. The defined distance (50) is repeatedly adjusted by means of the control values. In accordance with one aspect of the invention, the distance values along the movement path (28) are determined by means of a first grid spacing (46). The control values are determined along the movement path (28) with a second grid spacing (44). The first and the second grid spacings (46, 44) are different.

A mounting element (12, 12a, 12b) for securing components, in particular profile bars, and a cap (14, 14a, 14b) for covering the mounting element (12, 12a, 12b) are provided. Indentations (31, 39) are provided in lateral ribs (22, 36) of the mounting element (12, 12a, 12b) and/or of the cap (14, 14a, 14b). This makes the grip better and/or facilitates aligning the mounting element (12, 12a, 12b) and/or the cap (14, 14a, 14b).
摘要:
A device (10, 10′, 50) for furnishing material (12) to work stations is proposed. The device (10, 10′, 50) has at least one reservoir, embodied as a chute (14, 14′, 54), for the material (12). A discharge point (16, 16′, 56) having a gripper tongue (18, 18′, 58) adjoins the chute (14, 14′, 54). The chute (14, 14′, 54) and the discharge point (16, 16′, 56) are embodied as parts separably connected to one another. The discharge point (16, 16′, 56) can be disposed on one of the two face ends (36, 40, 76, 110) of the at least one chute (14, 14′, 54). By means of this arrangement, it is possible with only a few different parts to achieve great versatility in terms of the storage volume of the device (10, 10′, 50).
