Abstract: A projection device for smart glasses. The projection device includes an image generating unit for generating at least one first light beam representing image information, and at least one deflecting element, which is configured to deflect the first light beam in the form of a second light beam representing first image information, and to deflect the first light beam in the form of a third light beam representing second image information, into a first field of vision and/or into a second field of vision of an eye; the second light beam and the third light beam differing with regard to a beam divergence; and the second field of vision and the first field of vision at least overlapping.

Abstract: A method for projecting image content onto the retina of a user using an optical system. Image data are captured using the image processing device. A first subset of the image data is blanked, thereby generating an active second subset of image data. The first and second subsets make up the total amount of the image data. The projector unit is controlled using the image data such that there is always only one eye box, generated on a common imaging path, with the same active image data arranged in the region of a first pupil region of the user. The first pupil region surrounds the pupil center. A portion of the eye box is arranged with a portion of the active image data within a second pupil region of the user. The second pupil region surrounds the pupil center. The second pupil region is arranged within the first pupil region.

Abstract: The method and the device serve to treat the flue dust formed during the production of nonferrous metals. After the addition of sulfur and/or a sulfur compound, the flue dust is heated, and volatile compounds are separated in a downstream offgas treatment unit. The flue dust is heated in an inert atmosphere.

Abstract: A process for electrolytic production of fine-grained, single-phase, metallic alloy powders, especially powders of intermetallic compounds as well as noble metal alloy powders, is described in which powdery metallic precipitates are galvanically produced on the cathode from an electrolytic precipitating bath known in the art, which contains in solution the metals to be precipitated, under electrolysis conditions causing a powder precipitation known in the art. For the production of alloy powders with defined properties, it is determined, first in preliminary tests by gradual increase of the cathode potential with otherwise constant process parameters, the minimum cathode potential at which single-phase alloy powders result and then the powder precipitation is potentiostatically performed in a cathode potential at or above the minimum for the single-phase alloy precipitation.
