  • Patent number: 10565468
    Abstract: An object tracking system suitable for use on an automated vehicle includes a camera, a radar-sensor and a controller. The controller is configured to assign a vision-identification to each vision-track associated with an instance of an object detected using the camera, and assign a radar-identification to each radar-glob associated with an instance of grouped-tracklets indicated detected using the radar-sensor. The controller is further configured to determine probabilities that a vision-track and a radar-glob indicate the same object. If the combination has a reasonable chance of matching it is includes in a further screening of the data to determine a combination of pairings of each vision-track to a radar-track that has the greatest probability of being the correct combination.

  • Patent number: 10557743
    Abstract: A fill level measuring device designed for the generation and emission of a transmission signal, wherein the transmission signal includes at least one frequency ramp. In order to determine the level of a filling material in a vessel, only frequencies within a fundamental frequency interval are used. In this case, the minimal frequency of the fundamental frequency interval is greater than the minimal frequency of the frequency ramp and/or the maximal frequency of the fundamental frequency interval is smaller than the maximal frequency of the frequency ramp. The approach provides a reduction of power peaks in the frequency spectrum of the mean power of fill level measuring devices, which peaks result from times in which the fill level measuring device emits a constant frequency before the beginning of or after a frequency ramp.
