Patent number: 10860298Abstract: A computer-implemented method for editing one or more properties of one or more model elements in a block diagram of a technical computing environment. The model elements include blocks and variables in blocks, wherein one or more properties are assigned to each model element. The technical computing environment has a model editor, a data definition tool and a code generator. A processor of a host computer opens a block diagram in the model editor, displays a list of model elements present in the block diagram, receives a selection of one or more model elements, highlights the selected model elements, receives an edit command to set a new value for a chosen property of the selected model elements, and sets the chosen property to the new value. A non-transitory computer readable medium and a computer system is also provided.Type: GrantFiled: November 6, 2018Date of Patent: December 8, 2020Assignee: dSPACE digital signal processing and control engineering GmbHInventors: Torsten Pietzsch, Wolfgang Trautmann, Christian Witte

Patent number: 9023260Abstract: A molded part and a method for producing the molded part. The molded part is rotationally symmetrical or at least partially annular in cross section and formed by a plasticized polymeric mass containing fibers being injected through an injection opening into a cavity of a molding tool. Once the polymeric mass has solidified, the molded part is removed from the tool. Injection into the cavity takes place through at least two injection openings in such a way that the fibers are aligned predominantly in the main stress directions of axial tension and torsion in the molded part.Type: GrantFiled: April 9, 2009Date of Patent: May 5, 2015Assignee: VOSS Automotive GmbHInventors: Günter Sieper, Peik-Christian Witte
