摘要:
The invention relates to a method for ascertaining material characteristics of an object, in particular optical properties of preferably semi-transparent objects. The aim of the invention is to obtain material characteristics without complex measuring methods. This is achieved in that spectrally resolved data from measured data of the object are calculated with spectrally resolved data of a reference body in order to ascertain the material characteristics, the measured data being ascertained with a confocal 3D measuring system.

摘要:
A method for detecting contour data of a three-dimensional object, where a grid of illumination points of a multi-point illumination is projected onto the object using an optical device and the illumination points are then projected back onto a sensor containing pixels. In order to improve signal-noise ratio and reduce background signal, it is proposed that a grid of illumination points of at least two multi-point illuminations are projected onto the object, that the beams of the illuminating points of are modulated in intensity and that a frequency-selective and/or phase-selective detection is performed of mutually associated first and second illumination points back-projected onto the sensor. The first illumination points derive from a first of the multipoint illuminations and the second illumination points derive from a second of the multipoint illuminations. Differences in intensity and/or frequency of the measurement signals of adjacent pixels of the sensor on which the mutually associated first and second image points are depicted are evaluated for the purposes of determining the contour data.
摘要:
A method and device for detecting the contour data and/or optical characteristics of an object, such as a tooth or a tooth restoration, based on an interference and/or autocorrelation measurement using an image sensor. To permit an exact surface detection in addition to a determination of the optical characteristics of the object, individual light beams strike the object, which are located at a distance from one another in such a way that no impact of reflected individual light beams takes place on immediately adjacent pixels of the image sensor.

The invention relates to a method for welding two welding parts (1, 3) by means of a fillet weld (11), wherein a first welding part (1), with a bearing surface at least in an edge area of an edge that is to be welded by means of a fillet weld, is brought into contact with a bearing surface of a welding part (3) and the welding energy (5) is supplied in an energy supply area during the welding process, exclusive of a surface (7) of the first welding part facing away from the bearing surface, said energy supply area being located at a predetermined distance from the edge of the first welding part. The welding energy is supplied in a direction, whereby the direction component thereof points perpendicular to the course of the fillet weld that is to be produced in the direction of an inner area of the first welding part, forming a welding angle of less than 90° with the contact plane of the bearing surfaces of the first and second welding parts. The welding energy is supplied until at least the energy supply area of the first welding part and a sufficient area of the second part, which is adjacent to the energy supply area of the first welding part, and also the material supply area located between the energy supply area and the edge of the first welding part are melted and fused together. The invention also relates to a welding part for carrying out said method and to an electric component with a printed conductor, which is welded to a cooling body of at least one power semiconductor element.

An embodiment of the present invention relates to systems and methods for dynamically detecting and visualizing actions and/or events in video data streams. In one embodiment, a method involves dynamically detecting and extracting objects and attributes relating to the objects from a video data stream by using action recognition filtering for attribute detection and time series analysis for relation detection among the extracted objects. In addition, the method may involve dynamically generating a multi-field video visualization along a time axis by depicting the video data stream as a series of frames at a relatively sparse or dense interval, and by continuously rendering the attributes relating to the objects with substantially continuous abstract illustrations. Finally, a method may also involve dynamically combining detection, and extraction of objects and combining with multi-field visualization in a video perpetuo gram (VPG), which may show a video stream in parallel, and which allows for real-time display and interaction.

The invention is directed to a ultrafiltration membrane that is capable for the retention of endotoxines and cytokine inducing substances (CIS) including bacterial DNA and/or DNA fragments from fluid and/or liquid media. The invention is further directed to a method of manufacturing such ultrafiltration membranes in a high quality and in an effective and time saving procedure, and to the use of such membranes for the retention of substances from fluids or liquids. The ultrafiltration membrane of the invention consists of a polymer blend comprising at least one hydrophobic polymer containing sulfur in its back bone, at least one hydrophilic, uncharged homo-polymer of polyvinylpyrrolidone and at least one polymer containing cationic charges. The method of manufacturing such a ultrafiltration membrane comprises dissolving at least one hydrophobic polymer containing sulfur in its back bone and at least one hydrophilic, uncharged polyvinylpyrrolidone and at least one polymer containing cationic charges in at least one solvent to form a polymer solution, subjecting the formed polymer solution to a diffusion-induced phase separation to prepare a ultrafiltration membrane, washing and subsequently drying of the ultrafiltration membrane.
