Abstract: An optical observation instrument according to the invention, in particular a surgical microscope or exoscope, comprises an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path for recording a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement.

Abstract: A handling cell for a machine tool comprises a loading interface, a handling unit with a handling robot, a feeding interface for a feeding cart, and a provisioning unit. The loading interface is arranged to be coupled to a workspace of a first machine tool. The feeding cart is used to transport workpieces that are arranged on loading aids. The provisioning unit moves loading aids between the feeding cart and a provisioning position for a transfer between the handling unit and the provisioning unit. A manufacturing system for machining comprises at least one machine tool, and a handling cell. The machine tool is configured for multi-axis machining and comprises a tool holder and a workpiece holder. The tool holder and the workpiece holder are movable relative to each other in at least three axes. The tool holder and the workpiece holder are mounted on a rear side of a workspace of the machine tool. The loading interface couples laterally to the workspace of the machine tool.

Abstract: A stacking device for handling loading aids for the automated feeding of a machine tool has a base, a stud frame that is held by the base and that supports a first vertical guide and a second vertical guide, and a first side and a second side. The first side has a vertically movable support segment for receiving a conveyor that carries two or more loading aids that are arranged one above the other. The support segment is moveable along the first vertical guide. The second side has a vertically movable lifting console for receiving at least one loading aid. The lifting console is configured to receive two or more loading aids arranged one above the other. The lifting console is moveable along the second vertical guide. The support segment and the lifting console are arranged facing away from each other at the stud frame.

Abstract: A method for determining a particle velocity of an aerosol by means of an aerosol measuring device. Aerosol particles flow through a measuring cell and are illuminated with an electromagnetic beam. The scattered light is registered and detected by a sensor. The temporal signal durations of the scattered light signals are determined, and the particle velocity of the aerosol is determined on the basis of the signal durations. Furthermore, the invention provides an aerosol measuring device designed to carry out the steps of the method according to the invention for determining the particle velocity of an aerosol. In addition, a computer program having program code means is provided, which computer program is configured to carry out the steps of the method according to the invention.

Abstract: A method assigns importance ranks to documents within repositories or databases, such as any database of documents such as books or other printed material, electronic documentation, and pages within the world-wide web. The method uses a corpus of indexed documents that has been annotated to the terms of one or more ontologies in order to assign a semantic similarity score to queries based on terms taken from the ontologies. A statistical model is used to test the significance of matches between query terms and documents or categories. The method results in an acceleration of over 10,000-fold for realistic queries and ontologies, and makes it practicable to calculate P-values dynamically or to keep database annotations and the related P-value distributions up to date by frequent recalculation.
