Abstract

The invention describes an apparatus that implements efficient coupling between a photonic integrated circuit (PIC) and a second optical element such as a fiber or laser, while at the same time allowing for efficient polarization management and/or optical isolation. It enables the packaging of PICs with large single mode fiber counts and in- and out-coupling of light with arbitrary polarization. The apparatus comprises a glass interposer that contains at least one polarization selective element together with a pair of lenses transforming a beam profile between the 2nd optical element and a polarization selective coupler on the PIC. The invention also comprises a method for fabricating the apparatus based on a subassembly of building blocks that are manufactured using wafer-scale high-precision glass-molding and surface treatment(s) such as thin-film coating.

Abstract

The invention relates to a method of qualitative control of at least one specific property of at least one stem cell, especially to a method of quality control for the pluripotency of pluripotent stem cells (PSCs). The invention further relates to the use of at least one nucleic acid molecule comprising at least one CpG dinucleotide for determination of germ layer-specific differentiation of at least one stem cell. The solution of the invention is based on epigenetic analysis of genomic DNA, with not only qualitative pluripotency analysis but also the option of estimating the differentiation potential of the cells. In conjunction with the differentiation of the iPSCs, the method of the invention additionally gives the user information as to the differentiability of the analysed stem cells into the three germ layers, which is considered to be an essential quality feature for pluripotent stem cells. The signatures according to the invention were selected with reference to early differentiation stages during development into endo-, meso- and ectoderm.

Abstract

The present invention relates to a method (10) for monitoring a plain bearing (50) of a wind turbine, a steam turbine or a compressor. The method comprises at least the following steps: - detecting (12) a structure-borne-sound signal of the plain bearing (50) by means of a structure-borne-sound sensor (52); - transforming (16) the detected structure-borne-sound signal into a time-frequency domain, in particular by continuous wavelet transform; - identifying (18) anomalies in the transformed structure-borne-sound signal by means of an autoencoder; - generating (20) anomaly data on the basis of the identified anomalies. The invention also relates to a system (40) for monitoring a plain bearing (50).

Abstract

The invention relates to a system for ascertaining internal load states of a mechanical component under the effect of external forces. The system has the following components: - an input interface which is designed to receive geometry data that represents the component, - a finite element pre-processor which is designed to divide the component into finite elements and assign at least one material property and/or at least one boundary condition to at least one element, - a finite element equation solver which is designed to provide a global stiffness matrix for the component, said global stiffness matrix indicating how the elements of the component are deformed on the basis of the assigned material property and/or boundary condition, and to identify the regions in the component in which the component is deformed and other regions in which the geometry of the component remains substantially unchanged despite the influence of external forces, and - a finite element post-processor which is designed to display the internal load state of the mechanical component under the effect of external forces. The system additionally comprises at least one trained neural network, wherein the trained neural network is trained to determine stiffness components of an element stiffness matrix from at least one finite element of the component, and the finite element is preferably located in the region of the component in which the component is deformed under the effect of external forces, thus resulting in a change in the geometry of the component. The finite element equation solver is additionally designed to use the element stiffness matrix determined by the trained neural network for the deformed element in order to update the global stiffness matrix and determine the internal load state of the mechanical component under the effect of external forces on the basis of the updated global stiffness matrix.

An additive application (56) of a mineral construction material is then carried out by means of the manufacturing device (12) from the first side of the reinforcement (28), wherein the mineral construction material passes through the reinforcement (28) to the second side of the reinforcement (28). The counter element (26) is guided from the counter device (18) to a current location of the additive application (56), particularly in order to reduce the formation of spray shadows and/or to smoothen a surface of the wall. The invention also relates to a system (10) for producing a wall.

Abstract

An electronic component is formed by a semiconductor component or a semiconductor-like structure having gate electrode assemblies for manipulating the quantum state of qubits in quantum dots. It comprises a substrate comprising a two-dimensional electron gas or electron hole gas. Electrical contacts connect the gate electrode assemblies to voltage sources. A first gate electrode assembly having gate electrodes is arranged on a surface of the electronic component to generate movable potential wells in the substrate. A second gate electrode assembly serves to generate a potential barrier, which is adjacent to the first gate electrode assembly. The gate electrode assemblies have parallel electrode fingers, whereby the electrode fingers of the first gate electrode assembly are periodically and alternately interconnected in order to effect an almost continuous movement of the potential wells through the substrate.

Abstract

The present invention relates to a method for the laser-induced transfer of various materials, in which method a pulsed, tunable laser beam source is used, and radiation energy is absorbed and a vapour bubble is formed directly in the transfer material. This method allows a precise and adjustable localisation, dimensioning and geometry of the vapour bubble produced in the carrier material, as a result of which it is possible to transfer defined volumes of materials to be transferred from a transfer carrier to a receiver carrier in a precise and contamination-free manner.
