Abstract: A method for situation-based processing of sensor data from a motor vehicle. Sensor data generated by sensors relating to the situation in the surroundings of the motor vehicle is transferred to a processing unit via a bus. The processing unit takes into account the transferred sensor data to determine an information requirement, and generates a request for additional sensor data on the basis of the determined information requirement and the load on the bus, and sends this request to the sensors. A corresponding device is also described.

Abstract: An electronic device includes a user input surface configured to receive a user touch location and a user force input, one or more sensors positioned relative to the user input surface and configured to detect a force applied to the user input surface, and a controller in communication with the one or more sensors. The controller is configured to detect a first sensor response utilizing a first force applied to the user input surface via the one or more sensors and a first position of the first force applied, wherein the first position is relative to the user input surface, simulate a multi-finger force being applied by utilizing at least the first sensor response to form simulated multi-finger data, and deploy a model associated with the multi-finger force, wherein the model is utilized to output a predicted force and predicted location of an applied force relative to the input surface.
Abstract: A method for determining a driving maneuver of a vehicle with a control unit includes receiving a measurement data relating to a traffic situation from a sensor, determining a current detection area of the sensor by evaluating the measurement data, and creating a sensor model based on the measurement data. An estimated detection area of the sensor from the measurement data is modelled through forward simulation based on a vehicle position of the vehicle. A change in the estimated detection area of the sensor due to a driving maneuver is determined along with the driving maneuver that causes an increase in the estimated detection area due to the sensor model.

Abstract: A method for operating a decentralized application by users of a blockchain. In the method, a first user proposes a state change on a state channel anchored in a blockchain. If a confirmation of the state change by the other users on the state channel does not occur, the first user prompts the other users to confirm within a predefined time span on the blockchain. If the confirmation also does not occur on the blockchain, the state change is carried out at the blockchain.
Abstract: A pump apparatus has a rotor shaft, a pump impeller connected to the rotor shaft, at least one axial bearing which rotatably supports the rotor shaft at a side facing the pump impeller, a magnetic pump stator, a magnetic pump rotor which is connected to the rotor shaft, a containment can which extends between the stator and the rotor, and at least one central support element which is mounted in the region of the pump impeller. The pump apparatus has an elastomer disk which is arranged between the support element and the axial bearing. The stator and the rotor are arranged with an axial offset with respect to each other. The stator and the rotor are provided as a result of the axial offset to produce an axial force F in the direction of the elastomer disk.

Abstract: A steering column sleeve includes (i) a translationally movable outer tube and inner tube, and (ii) an adjusting system for adjusting the relative position of the tubes. The adjusting system includes a screw for adjusting the axial position of the two elements. The adjusting system further includes an adjusting device for adjusting a resistance force opposing the relative movement between the tubes. The adjusting device has a friction pad and a clamping surface against which the friction pad moves between operating and adjustment positions. The adjusting system also includes a kinematic chain so that, beyond a threshold resistance torque transmitted by the screw to a single motor that it drives, its torque is transmitted to the adjusting device so as to move the friction pad from its operating position to its adjustment position.

Abstract: A computer-implemented unsupervised learning method of training a video feature extractor. The video feature extractor is configured to extract a feature representation from a video sequence. The method uses training data representing multiple training video sequences. From a training video sequence of the multiple training video sequences, a current subsequence; a preceding subsequence preceding the current subsequence; and a succeeding subsequence succeeding the current subsequence are selected. The video feature extractor is applied to the current subsequence to extract a current feature representation of the current subsequence. A training signal is derived from a joint predictability of the preceding and succeeding subsequences given the current feature representation. The parameters of the video feature extractor are updated based on the training signal.
