    摘要： The present invention relates to an ultrasonic transmission and reception device (1). Said device comprises a transmission circuit (20) for producing a transmission signal at its transmission outputs (21) and (21'), an ultrasonic transducer (40) that is suited to converting electrical signals into sound signals and sound signals into electrical signals, a transformer (10), the primary side (11) of which is connected to the transmission outputs (21) and (21') of the transmission circuit (20) and the secondary side (12) of which is connected to the ultrasonic transducer (40), and a reception circuit (30) for processing a received signal that is applied to its reception input (32). The ultrasonic transmission and reception device (1) is characterised in that the reception input (32) of the reception circuit (30) is connected to the transformer (10) via an additional winding tap (13) of the transformer (10), the additional winding tap (13) being incorporated into the transformer (10) such that the transformed transmission signal at the reception input (32) of the reception circuit (30) has its amplitude boosted with a lower gain factor than the transformed transmission signal that excites the ultrasonic transducer (40).

    摘要： A means is provided for determining the position and/or the movement of at least one object, in particular of a vehicle, in the environment of a movement aid by means of at least one acoustic signal identified as an echo signal reflecting off the object and received, said signal being transmitted by the receiving electro-acoustic converter, wherein a reverberation time (ND) after the transmission of the acoustic signal is measured and in the case of a match between the measured reverberation time (ND) and the known reverberation time of the electro-acoustic converter, the first detected echo signal (USE1) is recognised as the first echo signal originating from an individual reflection of the transmitted acoustic signal from the object, and the object distance (d) is determined from the transit time of the first detected echo signal, and/or if a measured reverberation time (ND) is longer than the known reverberation time, the transit time of the received first echo signal and therefore also the object distance (d) is estimated from the difference between the measured and the known reverberation time of the first echo signal.

    摘要： The inventive ultrasonic transducer (1) has a pot-shaped housing, the bottom surface of said housing being partly configured as an oscillating membrane (3). A stabilising ring is provided on the exterior surface of the wall of said pot-shaped housing. Said stabilising ring (6) gives the housing greater rigidity and restricts the ultrasonic oscillation essentially to the base of the pot shape (3) which forms the oscillating membrane. The propagation and reception beam of the ultrasonic waves can be shaped further by means of an additional sound-directing device (7) located in the area of the oscillating membrane (3).

    摘要： The invention relates to a radar device comprising means (10) for creating a carrier frequency signal, means (12, 12a, 12b, 13, 13a, 13b) for generating pulses, means (14, 14a, 4b, 15, 15a, 15b) for generating modulated radar pulses from the carrier frequency signal, means (16, 18a, 18b, 18c, 18d) for emitting modulated signals in the form of radar pulses, means (18a, 18b, 18c, 18d) for receiving radar pulses and means (20) for processing the received radar pulses. The means for receiving the radar pulses have an array containing several antenna (18a, 18b, 18c, 18d), the means (20) for processing the radar pulses have means for dividing the signal power between at least two different receiving branches (24, 26) and the invention is also provided with means (28a, 28b, 28c, 28d, 30a, 30b, 30c, 30d, 42) for generating various directional characteristics (32, 34) in the different receiving branches (24, 26). The invention also relates to a method for operating a radar device.
