Abstract: In a device for diagnosing a mechanical system driven by an electric drive motor, the drive motor thereof, and the shifting device thereof include at least one sensor for detecting the current curve in a conductor of the electric connection of the drive motor. The precision and the degree of detail of the diagnosis are to be improved compared to the prior art and expanded to include the drive motor and the shifting device in order to improve the efficiency and aim of the maintenance process carried out in response to the diagnosis. This is achieved in that the device additionally has sensors for detecting the voltage curves in the conductors of the electric connection of the drive motor, wherein each conductor is paired with a sensor for detecting the current curve and with a sensor in interaction with a sensor in order to detect the voltage curve.

Abstract: A method for scheduling or controlling the movements of a plurality of vehicles over a network of routes is disclosed. The nodes and edges of the network of routes are formed by route elements. The control and management of route elements by a central authority is complex and susceptible to disturbances. The method enables a simplification of the technical infrastructure that is to be maintained within the network and improves its availability and thus also the resistance of the network to technical disruptions. This is achieved in that any vehicle as an entity represented in a distributed ledger system enters into transaction agreements with the route elements, likewise represented as entities in this distributed ledger system, wherein each transaction agreement of a vehicle with a route element includes at least one time specification, which defines the period of time for which the route element is occupied by the vehicle.

Abstract: A method and a device for diagnosis and state monitoring of a wear and functional state of a junction, a crossing, a crossroads, rail joints, and/or track nonuniformities of a rail traffic path made of several tracks measures and stores swing acceleration in at least one direction when overtaking a rail vehicle on a junction, crossings or crossroads, in addition to rail joints or track nonuniformities on at least one rail vehicle component, the swing acceleration being produced on the rail vehicle component when overtaking the rail vehicle at the junction, crossing or crossroads, rail joints, track nonuniformites. The method also measures and stores the rail vehicle speed and determines and stores the travel direction and the place of the junction, crossing or crossroads, rail joints, track nonuniformities, carries out a control as to whether characteristic, predetermined threshold values of the measured swing accelerations have been exceeded.

Abstract: The invention relates to methods for determining the scope of detectability and readability of light signals with several light spots at a given surrounding radiant density per unit area. According to the invention, calculation of the scope of detectability is carried out with the rod of the assumption that the total radiant density per unit area or the total light intensity of the light signal is obtained by multiplying the radiant density per unit area or light intensity of a single light spot by the number of light spots.
