Abstract: A CMM has a measuring head for recording measurement values associated with an object having a plurality of geometric elements. Defined geometric elements are selected from the plurality of geometric elements and test features relating to the defined geometric elements are determined depending on demand data provided for the geometric elements. Initially, a first measurement sequence including first control commands for controlling the measuring head are determined depending on the test features. The first measurement sequence is modified before the individual measurement values are recorded in order to obtain a second measurement sequence with second control commands, which differ from the first control commands.

Abstract: A method is disclosed for correcting deviations in a production process of an article. Initially, measured 3D surface coordinates of a first article are obtained and used to create a virtual image of the first article that is displayed on a display apparatus that is fastened to the user's head. The virtual image is superimposed on a predefined model image of the article which is also displayed on the display apparatus to enable the user to detect any region(s) where the measured first article deviates from the predefined model. The user is then able, via a gesture (e.g., hand movement) or head movement, to select a particular region of deviation and control the desired corrective action to be performed on subsequently produced articles. The present method thereby enables the experienced user to subjectively select the region(s) requiring correction action and the degree and type of corrective action to be taken.

Abstract: A method for correcting deviations in a production process of an article, including: a) measuring surface coordinates of a first article, b) representing, in three dimensions, real measurement values from measuring the surface coordinates with a display apparatus that is fastenable or fastened to a user's head, c) representing, in three dimensions, a predefined model of the article using the display apparatus, d) comparing the predefined model to the point cloud or the point mesh, e) selecting at least one region from the point cloud or the point mesh which deviates from the predefined model, f) manipulating this region of the point cloud or the point mesh by means of the gesture or head movement control such that the point cloud or the point mesh in this region is matched to the predefined model, or approximated to the predefined model, or moved beyond the predefined model, g) transmitting at least one value of a deviation between the point cloud or the point mesh and the point cloud/point mesh obtained b

Abstract: The invention relates to a method for determining the co-ordinates of a workpiece (9). According to said method: a first co-ordinate system, which has a fixed position in relation to the workpiece (9), is defined; first co-ordinates of the workpiece (9) are measured using a first co-ordinate measuring device (3); second co-ordinates of the workpiece (9) are measured using a second co-ordinate measuring device (5); and a common set of co-ordinates is generated from the first co-ordinates and the second co-ordinates in the first co-ordinate system or in a second co-ordinate system, which has a fixed position in relation to the workpiece (9). The method can be used in particular to determine co-ordinates of a plurality of workpieces (9) during and/or after the production and/or processing of the workpieces (9).

Abstract: The invention is directed to a method for automatically generating travel paths to the next geometric elements to be measured when there is a collision of the probe 25 or the probe head 10, for example, with the workpiece 22. The method utilizes safety-reference surfaces (S1 to S5) placed in the form of an enclosing parallelepiped about the workpiece 22. The shortest collision-free connecting paths (P1-P2-P3) from one geometric element to the next are computed on these safety-reference surfaces.

Abstract: In the automated performance of multiple measurements on each of a succession of workpieces, the invention contemplates establishing a plurality of safety-reference positions (S.sub.1 to S.sub.7) along the programmed displacement path intended for the probe head (10) and its work-contacting probe pin. Any one of a variety of error signals developed in the course of conducting the measurement program on a given workpiece is operative to temporarily stop further conduct of the program and to instigate a repeated attempt to successfully traverse the part of the program in which the error signal occurred.

Abstract: Apparatus for measuring fluorescence comprises a metal block having a first recess for a sample mount and a second recess for a beam divider. A receiving bore connects both recesses and extends axially from the metal block. A radiation source and an optical focusing device are provided to introduce radiation into the receiving bore. Two exit bores extend from the recesses at an angle, and reflected or fluorescent radiation emitted by the sample and the beam divider pass through the exit bores. Detectors are at the exit bores to measure the radiation.

Abstract: Method for determining the total protein content or individual amino acids in flour, cereal flour and/or leguminous products or other substances by means of fluorescence analysis. The proteins and/or the individual amino acids are treated to attain a fluorescent effect or are self-fluorescent. The proteins and/or the individual amino acids are brought into suspension in their unpretreated form. The suspension is then fluorometrically measured by means of vertical transillumination. An apparatus is provided for practicing the method and comprises a primary radiation source for emitting a primary radiation to excite the fluorescent material, optical means for directing the primary radiation in a vertical direction onto the proteins and/or amino acids in suspension, at least one vessel for holding the suspension, through which the primary radiation can pass in a vertical direction, and receiving means and evaluating means for measuring the fluorescent radiation.
