摘要： The present invention benefits from the determination that pre-selected spectral bandwidths that avoid the spectrum of an electronic transition of a metal/alloy vapor allow for welds substantially free from detritus that may discolor the weld. Accordingly, the present invention provides analytical methods, welding methods and fiber lasers configured to provide high quality metal/alloy welds.

摘要： A unit cell of an artificial phononic crystal for building of an artificial phononic metamaterial, showing reduced mechanical vibrations in a defined frequency range with at least one band gap in the band structure dispersion relation of the unit cell. The unit cell includes at least one building block and at least one mechanical connection connected to the building block, showing reduced mechanical vibrations in a defined frequency range with tailored dispersion properties with at least one band gap is sought. This is accomplished by forming the building block as a toroid, with a central opening and a front surface from which a first multiplicity of struts, which are tiltable relatively to the principal direction, is extending from the front surface. More than one strut is inclined with respect to the principal direction so that a rotation of the toroid around the principal direction is possible.

摘要： Use of a sensor read out system with at least one fiber optical sensor, which is connected via at least one signal line to a processing unit as part of an additive manufacturing setup, for in situ and real time quality control of a running additive manufacturing process. Acoustic emission is measured via the at least one fiber optical sensor in form of fibers with Bragg grating, fibre interferometer or Fabry-Perot structure, followed by a signal transfer and an analysis of the measured signals in the processing unit, estimation of the sintering or melting process quality due to correlation between sintering or melting quality and measured acoustic emission signals and subsequent adaption of ion and electron beams, microwave or laser sintering or melting parameters of a ion and electron beams, microwave or laser electronics of the additive manufacturing setup in real times via a feedback loop as a result of the measured acoustic emission signals after interpretation with an algorithmic framework in the processing unit.

摘要： The method for producing the strain gauge device (10) comprises a first stop of producing the band (12). The band (12) has flexibility at least in the measuring zone (36). Then a sensor (22) comprising at least one measuring strand (30) and changing electrical resistivity in dependence of the strain is produced and arranged on or in the band (12) without pre-tension. Afterwards the shape of the band (12) is changed into a retaining working shape and thereby the measuring strand (30) is stretched to an amount of pre-tension.

摘要： A waveguide spectrometer includes at least one substrate layer with at least one waveguide. Each waveguide extends from an inlet face proceeding partly through the substrate layer to a reflecting element. A multiplicity of photo detectors is arranged on a front side of the substrate layer, while the photo detectors are electrically connected to an electronic read out system. The spectrometer can be made lightweight and easier to produce by forming the waveguides as surface waveguides, each showing a longitudinal opening with a width to the front side of the substrate layer between the inlet face and the reflecting element. The photo detectors are in print distributed at the front side on top of the substrate layer at least partly overlapping the longitudinal opening along an overall length of sampled region and the electrical connection of the photo detectors with the electronic read out system is achieved by a multiplicity of printed electrical conductors.

摘要： A method (200) for fabricating thin-film optoelectronic devices (100), the method comprising: providing a substrate (110), forming a back-contact layer (120); forming at least one absorber layer (130) made of an ABC chalcogenide material, adding at least one alkali metal (235), and forming at least one cavity (236, 610, 612, 613) at the surface of the absorber layer wherein forming of said at least one cavity is by dissolving away from said surface of the absorber layer at least one crystal aggregate comprising at least one alkali crystal comprising at least one alkali metal. The method (200) is advantageous for more environmentally-friendly production of photovoltaic devices (100) on flexible substrates with high photovoltaic conversion efficiency and faster production rate.
