Abstract: A method is for determining a speed of an object based on an ultrasonic pulse. The method includes emitting the ultrasonic pulse using a first ultrasonic transducer. The ultrasonic pulse having a defined signal profile. The method further includes receiving an ultrasonic signal using a second ultrasonic transducer, calculating a cross-correlation, with respect to frequency, of the ultrasonic signal with a filter signal which at least partially correlates with the defined signal profile, and determining a frequency shift between the filter signal and the received ultrasonic signal using a result of the calculated cross-correlation. The method also includes determining the speed of the object which reflected the emitted ultrasonic pulse using the determined frequency shift.

Abstract: A method is for the classification of temporally sequential digital audio data that describe acoustic signals that identify hazardous situations. The method includes calculating a large number of frequency spectrograms for stepwise progressive time intervals of the temporally sequential audio data, and forming a specific number of frequency segments for each octave of each individual frequency spectrogram. The frequency segments include a subset of the individual frequency spectrograms. The method further includes adding corresponding frequency segments of the octaves of each individual frequency spectrogram, calculating frequency components through the formation of mean values for the individual, added frequency segments in each individual frequency spectrogram, and generating a classification vector using a classifier and the number of frequency components of the large number of frequency spectrograms.

Abstract: A method recognizes an object in a surroundings of a vehicle. The vehicle has an ultrasonic sensor for monitoring the surroundings of the vehicle and for the transmission and reception of ultrasonic signals. In the method, sensor data generated by the ultrasonic sensor are received. Classification data that contain features to be classified, are subsequently generated from the sensor data. The classification data and/or the sensor data are hereupon entered into a classifier that has been trained with training data for assigning the classification data and/or the sensor data to object classes. Object information that indicates at least one of the object classes is output.

Abstract: In a method for cyclically measuring distances (d) and relative velocities (v) of objects using an FMCW radar sensor, the frequency (f) of a transmitted signal of the radar sensor is periodically modulated, each period (P) including at least two differing modulation patterns, a relationship between distance (d) and velocity (v) of the object being derived from a signal received for a single modulation pattern, and the signals received for multiple modulation patterns being adjusted to one another in order to determine one value each for the distance and the velocity per each measuring cycle. For the adjustment between a signal obtained for a modulation pattern in the instantaneous measuring cycle and the signal(s) obtained for other modulation patterns, the signals from at least one previous measuring cycle are utilized.

Abstract: A method for operating a control network includes a first control computer, a second redundant control computer and a plurality of data-processing appliances, wherein a connection between the computers and the appliances is provided by a redundant and diverse heartbeat. The connection between the computers is checked before operating the control network. If a test result is positive, a master function is assigned to the first computer. If the test result is negative, both computers connect the appliances to themselves in a defined sequence. When a predetermined number of appliances are connected to the first computer, the computer takes over a master function and the second computer takes over a standby function, or, when a number, which is less than the predetermined number, of appliances are connected to each of the two computers, a signal is produced which signals a fault state of the control network.

Abstract: A novel fibrous non-woven composite is provided that comprises as a first component substantially continuous coarse spun-bonded filaments of a thermoplastic polymer which exhibit molecular orientation, and as a second component fine discontinuous melt-blown microfibers of a thermoplastic polymer. The fibrous components are well admixed through their placement following their formation on the same equipment to form an integrated non-woven deposition in the absence of a discrete phase boundary between substantially homogeneous concentrations of the components, and are subsequently thermally bonded to form a unitary structure. The continuous coarse spun-bonded filaments provide good strength for a supporting function throughout the non-woven composite, and the fine discontinuous melt-blown microfibers perform an uninterrupted filtration and/or moisture transport function throughout the non-woven composite. The resulting product is useful in diaper, medical, and clothing applications.
