Abstract

An axial flux machine, in particular a single-sided axial flux motor, for an electrical machining device, includes a machine shaft, in particular a motor shaft, a disc-shaped stator, and a disc-shaped rotor which is arranged adjacent to the stator in the axial direction of the machine shaft. The stator is formed as a winding carrier for at least one stator winding and the rotor, which is connected to the machine shaft in a rotationally fixed manner, can rotationally moved relative to the stator. The axial flux machine further includes a housing for receiving the stator and the rotor. The housing is cylindrical, open on one side and formed with a substantially closed end face, and the housing fixes the stator in such a way that a defined air gap remains between the rotor and the stator. The axial flux machine can be arranged in an electrical processing device.

The invention relates to a method for producing a silicon layer system (310) comprising the following steps: providing a carrier substrate with a surface, wherein the carrier substrate is provided with an insulation layer formed on the surface; applying a first silicon layer to the insulation layer; structuring the first silicon layer to form trenches in the silicon layer, wherein the trenches extend through the silicon layer at least at points; passivating the first silicon layer, wherein the trenches are filled and a first passivation layer is formed on a side of the first silicon layer facing away from the insulation layer; and structuring the passivation layer, wherein first sacrificial regions and functional regions are formed in the first silicon layer and the sacrificial regions on the side of the first silicon layer facing away from the insulation layer are free of the passivation layer at least at points. The steps are repeated from the application step, whereby sacrificial regions and functional regions are produced in other silicon layers, and there is a subsequent removal of all sacrificial regions. The steps are carried out such that an electrical connection (390) including a specialised functional region is formed, with which an electrical contact between two elements (380) can be produced, wherein the one specialised functional region serves only the electrical connection (390).

Abstract

A method for generating a rules package describing the current traffic situation of a motor vehicle. A traffic sign recognition unit monitors the area in front of the motor vehicle, and is used to generate video data. Traffic signs are recognized and an encoder/decoder unit generates first sensor data and transmits them to an evaluation unit, which encodes the recognized traffic sign. As a function of the first sensor data, the evaluation unit requests second sensor data, which characterize the current traffic situation, from at least one further sensor. In response, the encoder/decoder unit encodes these second sensor data, transmits them to the evaluation unit and the latter compares them along with the first sensor data to traffic rules stored in a database. Individual traffic rules are selected and from the selected rules. a rules package is created which contains the selected traffic rules.

A method to compensate for projection errors when outputting images using a smart-glasses system. At least one image is produced using an arithmetic logic unit of the system. The image produced or an image to be output is transmitted by the arithmetic logic unit to a micro-electromechanical output unit, particularly smart glasses, of the system. Before the image is output by the output unit, a correction algorithm is executed to generate a corrected image to be output. Image regions of the corrected image to be output are assigned at least one stored position within the produced image via at least one stored transformation function depending in each case on a position within the corrected image to be output. At least one image-region parameter is ascertained for the image regions to be generated depending in each case on the stored position assigned to the respective image region to be generated.

Abstract

A method is for determining a reduced first amount of testing from a second amount of testing. The method includes provision of a binary matrix, and optimization of a cost function, which is dependent on test variables. Each of test of the second amount of testing is associated with a test variable, and the test variable characterizes whether the test is relevant. The cost function defines constraints: a first constraint is defined in that a result of a matrix/vector multiplication must be greater than or equal to a vector comprising only ones. The matrix of the matrix/vector multiplication is a matrix whose entries all have the value one. The entries of the binary matrix are subtracted, and the vector of matrix/vector multiplication is a vector comprising the test variables. A second constraint is defined in that the test variables are binary.

Abstract

A method for training a neural network for evaluating measurement data. The neural network includes a feature extractor for generating feature maps. The method includes: providing training examples labeled with target outputs; providing a generic knowledge graph; selecting a subgraph relating to a context for solving a specified task; ascertaining, for each training example, a feature map using the feature extractor; ascertaining, from the respective training example, a representation of the subgraph in the space of the feature maps; evaluating an output from the feature map; assessing, using a specified cost function, to what extent the feature map is similar to the representation of the subgraph; optimizing parameters that characterize the behavior of the neural network; and adjusting the evaluation of the feature maps such that the output for each training example corresponds as well as possible to the target output for the respective training example.

Abstract

An object is to improve mountability of a brake system to a straddle-type vehicle while considering safety. An object is to improve mountability of a brake system to a straddle-type vehicle while considering safety. In a brake system, a mechanism portion includes a friction applying device which brakes a wheel of a straddle-type vehicle with a frictional force corresponding to a movement of an operator, an operator movement sensor which detects the movement of the operator, and an actuator which is unitized with the friction applying device. During normal braking, a control unit controls an output of the actuator based on a detection result of the operator movement sensor to change the frictional force applied to the wheel by the friction applying device. Further, when the actuator is in a non-energized state, the friction applying device applies a frictional force to the wheel.
