  • Patent number: 11604137
    Abstract: Described herein is a method and system for classifying rock types in a rock body. The method comprises the steps of obtaining spectral data from a spectral measurement (202) of a surface region of the rock body and then determining a first spectral ratio between two wavelength bands of the spectral data. From the first spectral ratio it can be assessed (204) whether the measurement is a high-angle measurement, and if the measurement is not a high-angle measurement then a further spectral ratio between two further wavelength bands of the spectral data is determined (208). The further spectral ratio is then compared (210) with a corresponding diagnostic criterion to assess whether the surface region comprises a first rock type associated with the further spectral ratio and diagnostic criterion.

When the driving arm bends to a +x side, the base part flexes so that a connection position in the base part is displaced to one side in the z-axis direction. The cross-section of the driving arm perpendicular to the y-axis direction causes a bending stiffness to the +x side and to the other side in the z-axis direction is smaller than a bending stiffness to the +x side and to the one side in the z-axis direction.

    Abstract: The present disclosure is directed to a software tool that engages in a pattern matching technique. In one implementation, the software tool retrieves a two-dimensional drawing and identifies walls as lines, rotates the drawing until a threshold number of lines are aligned with either the X or Y axes, discards lines that are not aligned with either the X or Y axis, identifies intersection points, identifies a subset of intersection points that have a maxima or minima coordinate, constructs a data library indicative of the relative positions of the points in the identified subset; and compares the constructed data libraries for the two-dimensional drawing to data libraries constructed for another two-dimensional drawing.

  • Patent number: 11269122
    Abstract: An optical device includes an optical system and a spectrally selective component arranged in a beam path and configured to spectrally influence light that propagates along the beam path. The spectrally selective component comprises an effective surface having a spectral edge that varies with the incidence site of the light on the effective surface. The effective surface of the spectrally selective component is arranged in the beam path at a point at which a variation of the spectral edge, which is caused by a variation of the incidence angle at which the light is incident onto the effective surface, is at least partly compensated for by an opposite-direction variation of the spectral edge which is caused by a variation of the incidence site. Alternatively, the effective surface is arranged in the beam path at the site of an image of a pupil of the optical system.
