Abstract: Displacement control device for variably adjusting the displacement of an axial piston hydraulic pump including a rotary shaft rotatable around a shaft axis. A torque can be applied for rotating the rotary shaft to open and close servo pressure lines to adjust the displacement volume of the axial piston hydraulic pump. Concentric to the shaft axis in a mid-portion of the rotary shaft a detent sleeve is positioned having an abutment area onto which, in the neutral position, a sliding element abuts. The detent sleeve, in operating conditions is rotatably fixed with the rotary shaft and turns with the rotary shaft and for neutral position adjustments in non-operating conditions, the detent sleeve and the rotary shaft are detachable from each other such that the rotary shaft can be turned relative and independently within the detent sleeve, which is held in its neutral position by the sliding element.

Abstract: Displacement control device (1) for variably adjusting the displacement of an axial piston hydraulic pump comprising a rotary shaft (10) mounted in a housing (20) and rotatable around a shaft axis (13) of the rotary shaft (10). The rotary shaft (10) having a first end (11) and a second end (12), wherein to the second end (12), which protrudes outside of the housing (20), a torque can be applied for rotating the rotary shaft (10) to open and close servo pressure lines (40, 45) arranged within the housing (20). The servo pressure lines (40, 45) can conduct hydraulic fluid to and from a servo adjusting unit capable to adjust the displacement volume of the axial piston hydraulic pump. The rotary shaft (10) further comprising a mid-portion (14) located between the first end (11) and second end (12).

Abstract: Techniques are described for transforming image data, such as two dimensional (2D) or partial 3D image data (image data), into a 3D model. Upon receiving image data including color information, the image data may be segmented into a plurality of segments using the color information. At least one height value may be assigned to each of the plurality of segments based on the color information, to define 3D image data. From the 3D image data, a 3D model may be generated, for example, for visualization, modification, and/or 3D printing. In some aspects, segmenting the image data may include comparing intensity values associated with pixels and forming edges in the image data if the intensity values differ by a threshold amount. Multiple edges may be determined and connected to form one or more contour loops, whereby the contour loop(s) may be extruded to produce complete 3D image data.

Abstract: Techniques are described for generating a three dimensional (3D) object from complete or partial 3D data. Image data defining or partially defining a 3D object may be obtained. Using that data, a common plane facing surface of the 3D object may be defined that is substantially parallel to a common plane (e.g., ground plane). One or more edges of the common plane facing surface may be determined, and extended to the common plane. A bottom surface, which is bound by the one or more extended edges and is parallel with the common plane, may be generated based on the common-plane facing surface. In some aspects, defining the common plane facing surface may include segmenting the image data into a plurality of polygons, orienting at least one of the polygons to face the common plane, and discarding occluding polygons.

Abstract: Techniques are described for transforming image data, such as two dimensional (2D) or partial three dimensional (3D) image data, into a 3D model. Upon receiving image data including color information, the image data may be converted into a height map based on the color information. The height map may be used to construct an image data mesh, which forms a 3D model. In some aspects, constructing the image data mesh may include associating vertices with pixels of the image data, connecting neighboring vertices to define at least one surface, applying texture to at least one of the surfaces, generating bottom and side surfaces, and connecting the bottom and side surface(s) to the textured surface to enclose a volume within the 3D model. In some aspects, the height map may include an edge based height map, such that color distances between pixels may be used form edges from the image data.

Abstract: The claimed subject matter includes techniques for designing three-dimensional (3D) objects for fabrication. An example method includes obtaining a three-dimensional (3D) mesh comprising polygons and obtaining a two-dimensional (2D) image. The method also includes receiving position information describing a location of the 2D image relative to the 3D mesh and modifying the 3D mesh based on the 2D image and the position information to generate an embossed 3D mesh that is embossed with the 2D image.

Abstract: The invention relates to a drive unit for a mixing drum that is disposed on a motor vehicle, in which an electric motor or a hydraulic drive comprising a displacement pump and a hydraulic motor can be used to drive the mixing drum. The low-power electric motor is used to drive the mixing drum at low rotational speed during the transport journey of the mixed concrete to the building site, while the hydraulic drive drives the mixing drum at high rotational speed during loading, mixing and discharging.
