摘要： An ultrasonic transducer for use in a fluid medium includes at least one transducer core having at least one electroacoustic transducer element, and further includes at least one housing having at least two housing parts. At least one first housing part at least partially encloses the transducer core such that a rear side of the electroacoustic transducer element which faces away from the fluid medium is accessible. Furthermore, at least one second housing part is connected to the first housing part. The ultrasonic transducer is essentially terminated by the second housing part on its side, which faces away from the fluid medium.

摘要： An ultrasonic transducer is described for use in a fluid medium. The ultrasonic transducer includes at least one piezoelectric transducer element and at least one matching element for promoting an oscillation injection between the piezoelectric transducer element and the fluid medium. The ultrasonic transducer also includes a housing (112), the piezoelectric transducer element being inserted in the housing. The housing has at least one opening facing the fluid medium, the matching element being inserted at least partially into the opening. The ultrasonic transducer also has at least one sealing element, which seals at least one intervening space between the matching element and the housing in such a way that an inner space of the housing is at least largely sealed from the fluid medium.

摘要： A method and a computer system for operating at least two interconnected control units. The control units access sensor data and each execute at least one computer program for controlling operational sequences, in particular in a vehicle. The control units exchange synchronization information with one another. In order to design and refine a computer system in a way that will enable even especially complex operational sequences, as required in a modern motor vehicle, for example, to be controlled and/or regulated simply and cost-effectively with the aid of the computer system, using conventional control units, the control units execute the same computer program time-synchronously using a settable time lag.
