  • Publication number: 20190250146
    Abstract: A process for carrying out an allergy test is based on a blood sample being taken. The blood sample is contacted in vitro with at least one allergen. At least one allergic reaction or the absence of the at least one allergic reaction is observed via a microscope (11) directly and/or optically. To make it possible to carry out an allergy test with a higher validity and/or better accuracy, a position of granules is observed via the microscope (11). The granules are observed in different planes or horizontal planes.

  • Publication number: 20190071088
    Abstract: A trailer backup assist system is provided herein. The system includes a calibration feature for calibrating an imaging device used for hitch angle detection. The system also employs multiple hitch angle detection methods, a number of which may run in parallel to increase the intervals at which a hitch angle can be measured. The system additionally includes a predictive feature in which a hitch angle can be predicted in instances where a trailer sensing device fails. The system is further configured to estimate a trailer length and generate steering commands that are invariant to the estimated trailer length under certain conditions.
