  • Patent number: 11048962
    Abstract: The invention relates to a method and to a device for determining the articulation angle of a combination, consisting of a towing vehicle and a trailer attached using a tongue, by identifying the hitch tongue using a digital back-up camera with variable exposure times, the following steps being carried out: a) recording a first color image of the rear environment of the towing vehicle, the color image being based on the HSY color space, b) analyzing the hue values, saturation values and brightness values of adjacent surfaces of a vehicle-environment region that is to be evaluated, c) determining the tongue from the first color image using an edge detection method in order to determine the articulation angle if the hue values, saturation values and brightness values of adjacent surfaces in the region that is to be evaluated are substantially equal, “substantially equal” meaning that the values of hue, saturation and brightness of adjacent surfaces differ by at most a first threshold in percent, d) recording a

  • Patent number: 10207597
    Abstract: A fuel cell system including: a fuel cell stack; a cathode gas supply system including a cathode supply path for feeding cathode operating gas into the fuel cell stack and a cathode exhaust gas path for discharging cathode exhaust gas out of the fuel cell stack, and a fuel cell cooling system for cooling the fuel cell stack including a coolant path into which the fuel cell stack is integrated so as to transfer heat is provided. It is provided that the cathode gas supply system also includes a turbine arranged in the cathode exhaust gas path, and the coolant path of the fuel cell cooling system in the flow path of the cathode exhaust gas downstream from the turbine is in heat-transferring contact with the cathode exhaust gas path. This achieves a cooling of the coolant by the cathode exhaust gas and a heating of the cathode exhaust gas by the coolant.

  • Patent number: 9754000
    Abstract: According to one general aspect, a method may include replicating, to a software-as-a-service application, a plurality of pieces of master data from a physically remote master database. The method may also include converting the plurality of pieces of master data into one or more pieces of local data of the software-as-a-service application. The method may include changing one or more of either the pieces of master data or the pieces of local data. The method may further include synchronizing the changed pieces of either master data or local data between the remote master database and the software-as-a-service application.
