Abstract: The invention relates to a device for the pressure-tight feedthrough of a line comprising a deformable jacket through a feedthrough in a wall which separates a first pressure area from a second pressure area with a sleeve surrounding the line in the area of the feedthrough, which has at least two spaced annular constrictions, notches, grooves or the like created by forming, between which the material of the jacket is compressed by forming into an integral ring seal acting between the jacket and the sleeve, where the sleeve is being pressure-tightly connected or being connectable to the wall around the feedthrough, at least from one side. Furthermore, the invention relates to a method for the manufacture of a corresponding device.

Abstract: A measurement system for optical measurement, in particular for measuring distance and/or position and/or speed and/or colour, defines at least one outer fixing point, which defines an outer coordinate system or lies therein, and at least one inner fixing point, which defines an inner coordinate system or lies therein. The two coordinate systems have a unique position relative to one another, which implies an adjustment or calibration of the system.
