Abstract: A self-propelled floor processing device with an evaluation unit, which is designed to navigate the floor processing device within an environment based on an area map and, during a movement, to determine a behavior parameter of the floor processing device and a movement path of the floor processing device. The evaluation unit is set up to analyze the behavior parameter and movement path, automatically determine a no-go area which the floor processing device must not traverse depending on the result of the analysis, and enter the determined no-go area in the area map or change a no-go area already entered in the area map.

Abstract: A gear actuator for shifting a gear includes an alley switch actuator, a gear switch actuator and a shift finger, which can be moved by the alley switch actuator and the gear switch actuator for the purpose of transferring a switching movement to the gear. An alley switch sliding element is connected with the alley switch actuator, and a gear switch sliding element is connected with the gear shift actuator. The shift finger is supported movably at the alley switch sliding element and at the gear switch sliding element.

Abstract: A latent heat storage for an internal combustion engine is described having a crystallizable storage medium for storing heat while utilizing the enthalpy of a melting procedure. The storage medium has a state of supercooled molten mass at ambient temperature. Furthermore, the latent heat storage includes a crystallization nucleus provider for providing a crystallization nucleus in the storage medium, in order to trigger a crystallization of the storage medium to release stored heat in the state of supercooled molten mass. Additionally, an internal combustion engine is provided having such a latent heat storage and a method for temperature control of an internal combustion engine. In a first step of the method, a crystallized storage medium is melted in order to store heat while utilizing the enthalpy of the melting procedure. The storage medium then cools down at most to the ambient temperature and forms a supercooled molten mass in the process.

Abstract: A commutator for an electrical machine, which has a plurality of laminations that have contact faces and are separated from one another by slots in which, in the laminations, at least one groove is provided in the contact face, which groove extends essentially in the longitudinal direction of the respective lamination. As a result, the frequency with which the brushes are excited by the commutator can be increased, which has a favorable effect on noise.

Abstract: A method for setting the operating point of a drive train whose purpose is to provide a mechanical and an electrical power output. The appropriate characteristic map is selected from a plurality of characteristic maps on the basis of the required electrical power, and, from this characteristic map, the operating point is selected on the basis of a plurality of kinematic and/or dynamic degrees of freedom.

Abstract: The present invention relates to a method for the sensorless electric measurement of the position of a rotor of a permanently excited synchronous machine that is fed by a converter, by means of measuring signals which are sent to an evaluation device that calculates the electric position of the rotor from the angular dependence of the current space vector at an impressed stator flux pattern, wherein the distribution of absolute values of the differential current space vector varies in approximation in sinusoidal manner with twice the value of the electric rotor position angle sought.
