摘要： A method and device are provided for measuring distance and relative speed of a plurality of objects with the aid of an FMCW radar, transmitted signals being reflected by objects, and the reflected signals being received and mixed with the transmitted signals. A combination of distance and relative speed values is assigned to the mixer output frequencies of each frequency ramp for each object, and the distance and relative speed of a possible object are determined from points of intersection of a plurality of distance and relative speed combinations. The apparent (unreal) objects are eliminated by modifying the frequency slope of at least one frequency ramp according to the random principle in a subsequent measurement cycle.

摘要： An ultrasonic sensor is described having a housing which has a circumferential side wall and a base surface. A transducer element for generating ultrasonic vibrations is mounted on the base surface. The side wall includes a lower side wall section, in which the side wall has an essentially rotationally asymmetrical profile in a plane parallel to the base surface, and an upper side wall section in which the side wall changes to an essentially rotationally symmetrical profile toward an upper edge of the side wall. In other respects, the present system provides a parking assistance system for a vehicle, having a control unit and such an ultrasonic sensor, as well as a method for manufacturing an ultrasonic sensor.

摘要： A method for deriving a respiration signal and/or a cardiac artifact signal from a physiological signal, in particular an impedance pneumography signal, includes detection of a heartbeat moment, storing the amplitude of the physiological signal at the heartbeat moment, and calculating and storing a learning signal, the learning signal being a function of a previous learning signal and the difference between the instantaneous amplitude of the physiological signal and the stored amplitude thereof. The learning signal is either read out starting each time with the particular heartbeat moment, for deriving the cardiac artifact signal, or subtracted from the physiological signal at each heartbeat moment for deriving the respiration signal.

摘要： In a method for operating an ultrasonic sensor in duplex mode, a transmission trigger for triggering an acoustic transmitted signal is transmitted from a control device for controlling the ultrasonic sensor to the ultrasonic sensor via a first duplex channel at a multiple of a resonance frequency of an ultrasonic converter in the ultrasonic sensor. The transmission trigger is subsequently divided down to the resonance frequency of the converter in the ultrasonic sensor. At least one acoustic received signal which corresponds to the acoustic transmitted signal and which is delayed with respect to the reflection at an object due to the acoustic propagation time is converted by the ultrasonic sensor, using the converter, to an electrical received signal which is transmitted from the ultrasonic sensor to the control via a second duplex channel at the resonance frequency of the ultrasonic converter in the ultrasonic sensor.
