Abstract: A measurement process is performed for each of a plurality of locations on a product of a fabrication process at which a parameter of interest characterizing the fabrication process is believed to be nominally the same, to derive measured signals for each location including at least one image. A dimensional reduction method is applied to a dataset of the measured signals, to obtain components of the dataset, including components indicative of variation between the images. For at least one of these components, one or more associated ones of the measured signals are identified, comprising at least one set of corresponding pixels in the respective images for the plurality of locations. The contribution of the identified measured signals in the dataset is reduced or eliminated to obtain a processed signal, and the parameter of interest is obtained from the processed signal.

Abstract: The invention relates to an insert for connecting an electrical connector to a wall (9) and to a corresponding method. The insert comprises an electrically conductive bolt (1) having a head (3), which extends along a first longitudinal axis (I), and a shaft (4), which is provided with at least one connecting means (5), and a ring (2), which has a through-opening (7) and extends along a second longitudinal axis (II). The head (3) comprises an outer contour which, at least in regions, is produced by the rotation about the first longitudinal axis (I) of a first line (L1), which is curved with a first radius (R1) and spaced apart from the first longitudinal axis (1). The through-opening (7) comprises an inner contour which, at least in regions, is produced by the rotation about the second longitudinal axis (II) of a second line (L2), which is curved with a second radius (R2) and spaced apart from the second longitudinal axis (II).

Abstract: An assembly tool for thread inserts includes a stem, a bush, and a locking means. The stem includes a first external thread extending over at least a portion of the stem and a second thread extending over at least a portion of the stem. The bush includes a thread that is engaged with the second thread of the stem. The locking means releasably locks a rotation of the stem relative to the bush. A length of the stem and a length of the bush complement one another such that the first external thread of the stem protrudes at least partially from the bush.
