Abstract: A steam generator for a fuel cell system having a heat exchanger (34) with at least one internal heat exchange surface, a water inflow pipe (46), a dripper head (52) with a flow passageway fluidly connected to the water inflow pipe (46). The dripper head (52) extends inside the heat exchanger (52) above the heat exchange surface for feeding water down onto the heat exchange surface for conversion into steam. The dripper head (52) has outlet holes (56) spaced along the flow passageway and between adjacent outlet (holes 56) the dripper head has a stepped profile on at least its underside to prevent droplets from adjacent holes coalescing. A fuel inflow pipe can have a section mounted coaxially to a part of the water inflow pipe (46). The fuel inflow pipe's section can surround the water inflow pipe's part.

Abstract: Method and system for generating an environment model for positioning include the generation of a 3D model of a scanned environment from a mobile entity, the 3D model being construed as a point cloud. A segmentation of the point cloud of the 3D model in a plurality of segmented portions of the point cloud is performed, and 3D objects are modelled directly from the point cloud by analyzing each of the segmented portions of the point cloud. The generated 3D model of the scanned environment is matched with an existing 3D model of the environment. A database representing of an improved 3D model of the environment is generated by aligning the existing 3D model of the environment and the generated 3D model of the scanned environment.

Abstract: A method and a system for generating and updating a digital road description database containing object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. A vehicle is collecting ambient data like images along multiple sections of its path, generating third data sets comprising at least location information and detailed object-based information. The third data sets are forwarded to a server database. The database identifies common groups of object reference points in multiple vehicle path sections and generates alignment functions for matching and/or aligning the at least one group of object reference points in at least two of the vehicle path sections relating to the same part of the road. The same alignment function is applied to all other third data sets of the same vehicle path section. The database updates the fourth data sets in the database based on processing the third data sets.

Abstract: A method and a system of a two-step object data processing by a vehicle and a database for generating and updating a digital road description database containing object-based information about road objects is disclosed. First, the server database comprises fourth data sets and generates and forwards first data sets to the vehicle, which are related to the area of interest of the vehicle. The vehicle is collecting a plurality of ambient data sets at least along a specific section of its path. It is performing the first step of object data processing by evaluating a selection of the plurality of ambient data sets and generating at least one second data set comprising at least location information and detailed object-based information. It further generates third data sets containing differences between the object-based information of the second data sets and the object-based information of the first data sets and forwards the third data sets to the server database.

Abstract: The present invention is concerned with improved fuel cell systems and methods.

Abstract: A fuel cell system comprising a controller, a temperature sensor that has a physical presence in a conduit within the system to measure the temperature of the fluid at a point within the conduit (Tg) and a wall temperature sensor for sensing a temperature of a wall of the conduit (Tw). The controller takes Tg and Tw as inputs and applies an equation with known constants to calculate measurement error of Tg based on the local flow temperature and geometry and arrives at a calculated temperature. The equation may be applied iteratively until the difference between the calculated temperature and Tg is below an acceptable value when the calculated temperature can then be assumed to be an accurate representation of the actual gas temperature at the Tg measurement point. The direction of calculation is controlled by the relative difference between Tg and Tw.

Abstract: A method and a system for precision vehicle positioning based on a digital road description database containing fourth data sets with object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. First data sets based on the fourth data sets are forwarded to a vehicle. The vehicle is collecting ambient data like images along its path, generating second data sets comprising at least location information and detailed object-based information. During driving and after generating second data sets, the vehicle tries to identify in the second data sets the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points as are contained in the first data sets.
