  • Patent number: 7634885
    Abstract: Wall element 2, especially for constructing a partition wall, for example in an exhibition, has a first connecting device with a least one first connecting element 12 to establish a connection with at least one other wall element 2?. the first connecting device is configured such that one wall element 2 can be connected with another wall element 2? without tools. The wall element includes an essentially frame-like basic body 18 and a second connecting device for releasable connection of at least one flat face element 30, 32, 34 to the basic body. the second connecting device is configured so that the face element 30, 32, 34 can be connected-with the basic body 18 without tools. The wall element 2 allows the partition walls to be largely assembled without tools. This saves time and assembly costs.

  • Patent number: 7602506
    Abstract: The invention relates to a method for contactlessly and dynamically detecting the profile of a solid body. At least one light beam is generated by a laser device and expanded to form a linear light band projected onto the moving surface of the solid body. Light reflected from the surface of the solid body is focused in an imaging device whose optical axis is at a fixed triangulation angle to the direction of projection of the laser device and which is arranged at a fixed based distance from the laser device. The reflected light is detected by a planar light receiving element at a frequency that is high by comparison with a speed of movement (v) of the solid body after which the measured values of the profile are obtained as a function of the triangulation angle and the base distance.
