Patent DE-19648420-A1 (DE)
Title: Raster counter for determination of width of graphical printing raster
Inventor: SCHMIDT HANS-THOMAS
IPC: G03F5/00
Filed: 1996-11-22
Abstract: The counter comprises a photographic film containing a measurement field 2 cm high but considerably longer, with curved lines 50% opaque and 50% transparent. Scales at the longer edges indicate lines per centimetre and per inch respectively. The lines approach continuously closer to one another towards the right-hand end without actually meeting. With the device laid on the object of measurement and rotated, a moire pattern forms a cross at one point from which the count can be determined from the appropriate scale.

Inventor: DORNIER IRENE
IPC: A47L1/02
Filed: 1997-04-15
Abstract: According to the inventive method for controlling an automatic cleaning device used for cleaning the surface of a window, the cleaning head is first advanced onto the window surface, approximately in the center or close to the edge, by means of a powered control system. This starting position is determined using the basic information for the building concerned provided in the plans of the building. The cleaning head is subsequently moved over the window surface as far as the window frame in direction X or Z, in a first seek-edges-mode, then moved along the window frame into the corner of the window, where the actual cleaning process starts. The frame of the cleaning head can be moved elastically in relation to the fixed structure so that the control device is able to determine whether the cleaning head is in contact with a window edge. In the case of windows without frames, a sensor can be provided, the signal of the sensor being detected by the control device.
