Publication number: 20240133939Abstract: Methods are provided for accelerating the insulation resistance measuring for determining an insulation resistance according to a pulse measuring method in an ungrounded power supply system. After indicating a target charging state of the network capacities available, a target point in time is calculated at which the network capacities have reached the target charging state. A first wait time is calculated from the current point in time as the difference between the target charging state and the current point. Alternatively, a target charging rate reflects a sufficiently stationary charging state of the capacitors, valid for measuring the insulation resistance. The target charging rate corresponds to the derivative of the first order of the target charging voltage and thus linked to the target point in time. Using the derivatives of the first order, a time difference is calculated as a second wait time.Type: ApplicationFiled: October 23, 2023Publication date: April 25, 2024Inventors: Zhongkui Huang, Matthias Gruen

Patent number: 11603803Abstract: A coupling arrangement is disclosed for the rotational coupling of a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow of a combustion engine to a pivot shaft rotatable about a pivot axis. A first coupling element has a coupling region coupled to a pivot shaft for rotation about the pivot axis. A preload element generates a force acting on the first coupling element and the second coupling element in a peripheral direction with respect to one another and generates a force acting in an axial direction between the coupling elements. One of the coupling elements includes two radially outwardly extending rotational coupling projections and the other coupling element includes a rotational coupling cutout receiving the projection. The one coupling element is held axially on the other coupling element by the preload element to prevent the projections from moving out of the cutouts.Type: GrantFiled: January 19, 2022Date of Patent: March 14, 2023Assignee: Purem GmbHInventors: Matthias Grün, Markus Birgler, Markus Lory, Andreas Wacker, Annika Zeumer, Ralph Schenk, Miljenko Novosel
