  • Patent number: 6943823
    Abstract: A method for producing height images of technical surfaces with microscopic resolution uses a confocal measuring microspace. The sample to be measured is displaced in the direction (Z direction) towards the microspace in a controlled manner and images are produced at defined distances with a digital camera. The digitized images recorded are transmitted to a controller (PC) for further processing and evaluation and the light intensity maximum for every pixel is detected, the position of the maximum indicating the height of the sample to be measured. The sample is displaced in a continuous manner and that the image exposures are triggered at discrete localized distances. The intensities of the N individual images recorded and digitized in the above manner are stored in the PC in such a manner that a number N of subsequent storage locations is occupied for every pixel.

  • Patent number: 5224389
    Abstract: A method for taking samples from a groundwater monitoring site realized by measuring an electric conductivity of contaminated groundwater during operating a pump at high r.p.m. and by controlling a predetermined minimum variation of the electric conductivity over a predetermined period of time with subsequent operating of the pump at low r.p.m.
