Abstract: Embodiments of the invention provide a cutting blade assembly operably coupleable to a fluid pump. The cutting blade assembly comprises a cutting plate and a cutting hub. The cutting plate may have a front axial surface, an opening, and a plurality of cutting features. Each of the plurality of cutting features may define a pair of cutting edges. The cutting hub may be disposed at least partially within the opening of the cutting plate and may have a cutting arm and fin adjacent to the front axial surface. The cutting arm may define an arcuate front surface having a leading edge. When the cutting plate and the cutting hub are rotated relative to each other, the leading edge of the cutting arm may pass adjacent to the plurality of cutting features so that the relative rotation of the cutting plate and the cutting hub defines a cutting action between the cutting arm and each cutting feature.

Abstract: Techniques are disclosed for programming a luminaire position for light-based communication (LCom) luminaires within an array of luminaires using position information provided by passing mobile computing devices. This position information can be received as, for example, as a specific coordinate (e.g., x-y coordinates of a grid-based map) or as movement data of the mobile computing device relative to an initial known reference location. The disclosed techniques can be used, for example, to reduce the time, labor, and expense associated with programming and re-programming a luminaire with a luminaire position, and to increase the flexibility of navigation system installations. In some cases, the disclosed techniques can be used, for example, to improve the precision of a luminaire position programmed into a newly installed luminaire.

Abstract: A sorting device having at least one control unit for sorting mixtures of individual elements in sorting units according to at least one characterizing feature of the individual elements and having at least one conveyor belt. The sorting device comprises at least one buffer unit having at least two displaceable storage elements for intermediate storage of individual elements.

Abstract: A method of sinking a bore hole in underground formations which have at least one special stratiform formation which features vastly differing formation pressures in respect to a formation adjacent to it in the sinking direction and in which a drilling tool carried at the bottom end of a drill line and having a drill bit driven by a deep drilling motor drills out a first part of a bore hole which extends to a point close to the boundary area of the special formation, characterized in that upon subsequent sinking of a further part of the bore hole by the casing string which passes through at least one special formation, a tubular outer casing with a bottom end carrying a driven drill head is entrained, the bore hole being lined by this, at least in the region of the special formation.
