Abstract
A method for transmitting data from an ultrasonic sensor to a computer system includes forming a feature vector signal from an electric reception signal; recognizing signal objects in the reception signal and classifying the signal objects according to predetermined signal object classes. The signal objects are forms or sequences of forms. At least one object parameter allocated to the signal object and one symbol for the signal object class are allocated to each signal object, or for each signal object, at least one signal object parameter and a symbol object are determined. The method further includes transmitting the symbol and the at least one signal object parameter to the computer system as data of a recognized signal object.
