Abstract: The invention relates to a method for fueling fuel cell systems (Sys A, Sys B) which are operated in an assembly (10) of a plurality of fuel cell systems (Sys A, Sys B), and to a fuel cell system assembly (10). According to the invention, a method is provided by means of which a load (100) operated by the assembly (10) can continue to be operated while a fueling process is carried out by a fueling device 20 assigned to the fuel cells (FC 1, FC 2) of the fuel cell system (Sys A, Sys B).

Abstract: A method calculates an excavation volume that was excavated by a construction machine using a tool. A motion trajectory of the tool over time is determined using one or more of the following sensors: inertial measurement unit, angle sensors, and linear sensors. At least part of the motion trajectory is classified based on machine load data as an excavation trajectory during which excavation occurs. The excavation volume is calculated using the excavation trajectory and dimensions of the tool.

Abstract: A method is for putting down a tool of a construction machine. A position and an orientation of the tool relative to the construction machine or to a direction of Earth's gravity is determined by one or more of the following sensors including: an inertial measuring unit, an angle sensor, a linear sensor, and/or by an algorithm for determining a kinematic chain of the construction machine. Moreover, an orientation of at least one part of the construction machine, which part touches the ground, and which orientation characterizes an orientation of the construction machine relative to the ground, is determined relative to Earth's gravity. Based on this determination, movement of the tool is controlled, in order to bring a lower face of the tool to the same level and in the same orientation as the at least one part touching the ground, for putting down the tool.

Abstract: A method and a system for guiding a vehicle are provided, which utilize information regarding the vehicle's position. The position of the vehicle is ascertained exactly to the correct lane, and for at least a part of the traffic lanes of specifiable traffic routes in the surroundings of the vehicle, the traffic situation is ascertained. An estimation of traffic lanes is undertaken in the light of specifiable criteria by the evaluation of the vehicle's position and the traffic situation, thereby enabling the driver to select the most favorable lane in terms of desired criteria, e.g., minimizing lane changes, minimizing travel time, etc.
