  • Patent number: 11865761
    Abstract: An extrusion head and a method for producing an elongated hollow body as an extrudate of an extrusion of extrusion material are provided. The extrusion head includes: a housing; a mandrel mounted in the housing, and a mouthpiece arranged downstream of the mandrel in a direction of extrusion. The extrusion material can flow around the mandrel in the direction of extrusion of the extrusion head. The mandrel includes an end-side mouthpiece section arranged in an opening of the mouthpiece so as to form a circumferential gap between the end-side mouthpiece section and an opening in the mouthpiece, and the mandrel is pivotable about at least one axis transverse to the direction of extrusion to change a geometry of the circumferential gap.

  • Patent number: 10489524
    Abstract: A method for generating synthetic data records which include datasets that capture state-based transitions, according to which a state transition family is randomly selecting, according to the distribution of samples between the different clusters of users and the context variables are randomly sampled according to their distribution within the chosen cluster. The relevant Markov Chains models are selected according to the sampled context and the initial state of the sequence is randomly selected according to the distribution of states. A random walk process is initialized on the graph models and the random walk is performed process on each context separately, assuming context independency. The cause condition of the current transition is sampled for each state transition, based on the distributions on the selected edge.

  • Patent number: 9846062
    Abstract: A method of collecting event data in a wind park installation including a plurality of wind turbines is provided. Each wind turbine includes a satellite-based clock. In each wind turbine, a first time signal is distributed from the satellite-based clock to at least one node in the wind turbine. In the at least one node, events happening in at least one subsystem connected to the node are detected. When an event is detected, event data including an information about the event is collected. For each piece of collected event data, a timestamp is added to the piece of collected event data characterizing a corresponding instant of time when the event was detected. The timestamped event data is stored for later inspection.

  • Patent number: 9186825
    Abstract: The invention relates to a method for producing a pellet from powdered material with the method steps: during a pressing process, a tipping of the upper and/or lower force transmission bridge and/or the upper and/or lower die plate and/or a force causing this tipping is measured; depending on the determined measurement results, the upper drive units and/or the lower drive units are moved asynchronously in relation to each other during the pressing process such that the caused tipping is compensated.

  • Patent number: 8587140
    Abstract: A method for estimating an achievable power production of a wind turbine, which is operated with a reduced power set point is provided. The method includes determining the values of at least two parameters, inputting the values of the at least two parameters into a neural network, and outputting an output value from the neural network. The at least two parameters are indicative of an operating condition of the wind turbine. Thereby, the output value is an estimate of the achievable power production of the wind turbine. A control system which is adapted to carry out the described power estimation method is also provided. Furthermore, a wind turbine which uses the control system adapted to carry out the described power estimation method is provided.

  • Publication number: 20080140436
    Abstract: A user of a management system, with which the user's reachability is managed, is assigned a reachability matrix in the system. This reachability matrix stores, in the form of reachability records, the respective reachability of the user via the communications media available to him in relation to a plurality of possible statuses. When events occur that result in a change of status with respect to the statuses recorded in the user's matrix, a reachability record of the user's matrix is defined as the actual reachability vector for the respective user on the basis of rules stored in the system, which reachability vector contains information for each medium available to the user for communication as to whether the user is at the moment to be reachable via the respective communications medium. For each communications medium affected by the change, the management system may generate control signals.
