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： In order to refine a device and a method for registering, detecting, and/or analyzing at least one object, a registration range and/or at a detection gate being displaced at a scanning speed over a measuring range, in such a way that a target-unique velocity measurement is ensured in continuous detection operation with low latency time and resistance to fluctuations, it is provided that, the receive circuit be divided into at least two channels, which are operable separately from one another, in particular using at least one power divider unit connected downstream from the output terminal of the I/Q mixing unit, of which the first channel of the receive circuit is designed for the purpose of displacing the registration range and/or the detection gate at a constant scanning speed over the entire measuring range, and the second channel of the receive circuit is designed for the purpose of displacing the registration range and/or the detection gate at a variable, in particular reducible scanning speed over the measuring range and/or setting the registration range and/or the detection gate at a predefinable position within the measuring range for a predefinable period of time at a negligible scanning speed.

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.
