Abstract: A plastic container manufactured from a preform with a mass share of at least 80% polyester and possibly an additive from the group consisting of dyes, fillers, catalysers, additives and lubricative additives. The plastic container comprises a container neck and a container shoulder which connects with the container neck and merges into a container body closed by a container base. The container shoulder, the container base and the container body are exclusively reshaped by a 2-stage stretch blow moulding method. The polyester is a copolyester and comprises groups which originate from the monomers cyclohexanedimethanol (CHDM) and/or monoethylene glycol (MEG), terephthalic acid (TPA) or its derivatives and isophthalic acid (IPA) or its derivatives. At least a part-region of the container body and/or of the container shoulder comprises a sharp edge with a radius of less than 0.5 mm. A method of manufacturing the plastic container is also described.

Abstract: Described are methods of estimating a physical property associated with a region of a sports article. The method includes determining a plurality of structural features within the region, determining, for each structural feature, a feature value, mapping each feature value to a physical property, wherein the mapping is based on a machine learning algorithm from a limited plurality of samples, and wherein each sample associates a feature value with a value of the physical property, and using the mapping to estimate the physical property for the region.

Abstract: A midsole for an article of footwear including a three-dimensional mesh including interconnected unit cells and methods of making the same. The interconnected unit cells each include a plurality of struts defining a three-dimensional shape. The interconnected unit cells are connected at nodes having a valence number defined by the number of struts connected at that node. The valence number of the nodes may vary to provide customized characteristics to zones or portions of the midsole. The plurality of interconnected unit cells may be organized in a warped cubic lattice structure. The warped cubic lattice structure and the size/shape of interconnected unit cells may vary to provide customized characteristics to zones or portions of the midsole. The three-dimensional mesh may be customized based on a biometric data profile for an individual, or group of individuals. The midsole may be manufactured using an additive manufacturing process.

Abstract: A converter configuration has at least one series circuit with at least two series-connected sub-modules which in each case have at least one switch and are installed in each case at a predefined electrical installation position the converter configuration. The converter configuration further has a central unit connected to the sub-modules to control the sub-modules. The sub-modules in each case have a memory in which an identifier, in particular a serial number, uniquely identifying the respective sub-module is stored. The sub-modules in each case have a control device which can forward the stored identifier to the central unit via a communication connection connecting the respective sub-module and the central unit.

Abstract: A converter outputs reactive power and has three phase branches connected to a phase of an alternating voltage source. Each of the phase branches has a phase module with a series circuit containing two-pole sub modules. A voltage which is dropped across each phase module corresponds to the sum of the voltages which are dropped across the sub modules. The first and the third phase branch are electrically connected to one another by a magnetically coupled throttle pair. A control device controls phase module currents. The control device contains current controllers which are associated with the phase modules, a decoupling unit for decoupling control differences by a computational during control of the phase module currents, a coupling unit for correcting the decoupled computational actuating variables in accordance with the magnetic coupling of the first throttle pair to obtain corrected actuating voltages, and a control unit for driving the sub modules.
