Method for the output of text information via a display in a driver information system in a motor vehicle is provided, the display having a predetermined display capacity, the extent of the information to be output being adapted to the capacity of the display, and the text information or the information elements to be output being divided into at least two components each. The pressure sensors provide acoustic pressure signals, which are provided to a signal processing system that determines the speed of sound amix of the fluid in the pipe 12 using acoustic spatial array signal processing techniques. By further subjecting the body to drying, heating and sintering, a dense cemented carbide body is obtained. The control signals control the camera functionality on the camera-equipped device. Electric current flows between the core and the electrodes.
