  • Patent number: 8024144
    Abstract: A surveying instrument (11) comprises a telescope unit having imaging optics and an array of optical detector elements, orientation sensors detecting an orientation of the telescope unit, rotation drives for rotating the telescope unit about a horizontal and a vertical axis, a controllable distance-measuring unit, and a processing unit. The processing unit comprises a memory storing instructions and calibration data for relating the location of each optical detector element to a sighting direction and a processor for: obtaining target region data; obtaining projection surface data (133) representing a projection surface (135), acquiring a set of pixel data representing a two-dimensional image of a target region, transforming the set of pixel data to a set of projected image data representing a projection of the image to the projection surface using the calibration data, and storing the projected image data as surveying data.

  • Patent number: 6436522
    Abstract: A process for the preparation of high-quality magnetic dispersions having an Hc>120 kA/m, a residual induction Mr/Mm≧0.9 and an orientation ratio of about 2.7 achieves, with a self-purging single-shaft blade-type kneading apparatus, very advantageous magnetic values of the magnetic coatings and excellent tape characteristics if at least the following features are fulfilled: a) the radial shear gradient in the gap between blade circumference and housing wall is from about 150 to about 1600, in particular from about 500 to about 1400, l/sec b) the circumferential velocity of the kneading blade is from about 20 to about 80, in particular from about 35 to about 60, cm/sec. The magnetic dispersion prepared can be used in particular for data and video recording media having high recording and storage rates.
