Abstract: A computer-implemented method trains a machine learning model. The method includes training the machine learning model on the basis of data representing at least two different vehicle environments. The machine learning model is trained, on the basis of data from a time-of-flight distance measurement of a distance between a key device and a vehicle, to determine a position of the key device relative to the vehicle.

Abstract: A method for a receiver locates an authentication unit of a motor vehicle. The method includes determining environment information relating to the receiver. The method also includes receiving a reception signal from a transmitter. The method further includes determining a relative position of the transmitter with respect to the receiver on the basis of the environment information and the reception signal.

Abstract: In one embodiment, the optoelectronic semiconductor component comprises at least one semiconductor chip for generating a primary radiation, and also an optical body disposed optically downstream of the semiconductor chip. A reflector surrounds the optical body laterally all around in a positively locking manner and is configured for reflecting the primary radiation and visible light. The optical body has a base surface facing the semiconductor chip and an exit surface facing away from the semiconductor chip. The optical body tapers in a direction away from the semiconductor chip. A quotient of the base surface and a height of the optical body is between 1 mm and 30 mm inclusive.

Abstract: The invention relates to methods for diagnosing the early stages of heart failure. The invention particularly relates to diagnosing class I and class II heart failure, based on the New York Heart Association (NYHA) classification system. The invention can also discriminate between healthy controls and heart failure patients in NYHA class III/IV.

Abstract: An operating system for driver assistance systems of a motor vehicle, has a plurality of operating elements which can be assigned to at least one operating group and which are disposed solely for operating driver assistance systems that can be assigned to at least one group. A corresponding function for operating the driver assistance systems can be assigned to each of the operating elements on the basis of adjustable combinations of operating modes of the driver assistance systems. The operating elements are disposed in order to operate an adaptive cruise control system, and in order to operate a lane departure warning system.

Abstract: A method for characterising the structure or sub-structure of a glycan or glycan derivative, experimentally derives the mass of an unidentified glycan molecule and compares the mass of the unidentified glycan molecule with identified and characterised glycan structures to select candidate structures for the glycan molecule. Next the mass of fragments of the glycan molecule is experimentally derived and theoretical fragmentation of the selected candidates is conducted. The mass of the fragments of the unidentified glycan molecule is matched with the mass of fragments theoretically derived from the candidate structures. Next scoring occurs to produce ranked confidence scores for each of the candidate structures by comparing the masses of the experimentally derived fragments with the masses of the theoretically derived fragments. Two scoring methods are disclosed namely segmentation and correspondence scoring.
