  • Patent number: 11002841
    Abstract: A method for the evaluation of signals of a rangefinder having at least one sensor point involves carrying out measurements cyclically, wherein the rangefinder emits a plurality of measurement points that indicate a distance from the sensor point. The rangefinder measures distances in a plurality of directions, and a horizontal angle is associated with each measurement point. The measurement points are differentiated into useful signals and interfering signals based on the distance. Measurement points with a distance below a first limiting value are identified as interfering signals, and measurement points above the first limiting value are identified as useful signals. Useful signals are associated with a first measurement area when they satisfy a predetermined condition for distance and horizontal angle. The quantity of useful signals in the first measurement area is determined, and a warning signal is emitted when the quantity of useful signals lies below a first threshold value.

  • Publication number: 20210081618
    Abstract: A method and a data processing device are disclosed for at least partially automatically transferring a word sequence composed in a source language into a word sequence in a target language with corresponding substantive content. By analyzing the word sequence and identifying terms with lexical ambiguity in the word sequence by comparing with a terminology database comprising terms with lexical ambiguity in the source language which are assigned a plurality of term identifiers depending on their number of meanings, an unambiguous term definition is provided for translating the word sequence into the target language by assigning a term identifier to the term with lexical ambiguity in the source language. This may render a machine translation less susceptible to errors.
