Abstract: Devices (100) for calming or mixing gases are provided. The devices (100) enable calming and/or mixing with an integrated mixing geometry, integration of sensors and actuators, and optimized conduction as well as provision of the mixed gases. The devises include one or more gas inlets, a gas outlet and a mixing system, including the integrated mixing geometry that is manufactured integrally and gas-tight in a manufacturing or joining process which is based on a formation of a form-fitting and/or force-fitting as well as gas-tight connection of plastic materials and/or metallic materials based on a printing technology or 3D printing technology.

Abstract: A method for obtaining approval of a sensor system for detecting objects in a vehicle's environment includes providing a combined probability distribution for deviations between output data from a sensor system and reference data at the programming level for detecting objects by the sensor system, at the sensor level and/or at the fusion level, sampling deviation combinations and calculating occurrence probabilities for the sampled deviation combinations using the combined probability distribution, subjecting the reference data to the sampled deviation combinations, processing these reference data with a fusion unit, and obtaining fusion results, removing occurrence probabilities from the combined probability distribution from which those fusion results are obtained that satisfy a predefined condition, and obtaining a residual probability distribution, taking the integral of the residual probability distribution and obtaining an absolute error probability, and obtaining approval of the sensor system based on

Abstract: A hybrid ultrasonic flowmeter includes at least a first sensing plane including four ultrasonic transducers (transducers) positioned in a parallelogram arrangement on a meter pipe wall including a first and second transducer pair. A first reflector is positioned between the first transducer pair on a first portion of the meter pipe wall, and a second ultrasonic reflector is between the second transducer pair on a second portion of the meter pipe wall opposite the first wall portion. The transducers have assembly angles and emission patterns for emitting ultrasonic beams to provide a plurality of direct measurement paths and a plurality of reflective paths involving a first reflective path involving the first ultrasonic reflector and a second reflective path involving the second ultrasonic reflector. A flow electronics module including a transceiver causes the transducers to transmit ultrasonic signals and processes sensing signals generated by the transducers for determining a volume flow.
