Abstract: The invention relates to a method for fast reconfiguration of GM clocks in the TSN network by means of an explicit teardown message. Carrying out a network-wide cleansing of the outdated information ensures that outdated GM information having a higher priority cannot overwrite new information. The current BMCA+ relies on the hold time mechanism in order to quickly carry out the GM reconfiguration on all nodes. The problem is solved by the introduction of a specific advertising schema for the BMCA+ protocol in order to resolve the described instability during the GM reconfiguration period. The method uses an announce+ message for an extra messaging that displays a clock having outdated information and disseminates new information in the complete network. The aim is to inform all clocks that outdated information is present such that the GM reconfiguration can be carried out quickly and without extra conflicts.

Abstract: An electric circuit breaker including a spring energy store drive having a spring and a manual winding device for manually tensioning the spring. In accordance with an embodiment, the manual winding device includes a rotatable latching disk, a latching pawl arranged next to the disk, and a manual actuating device connected to the latching pawl. The latching pawl is guidable into a latching toothed portion of the disk. The pawl is also capable of moving, owing to an actuation of the actuating device. As a result, the disk is capable of rotating along a preset desired rotation direction for tensioning the spring. The latching toothed portion is asymmetrical and a force transmission from the pawl onto the disk is possible along the desired rotation direction. The disk slides along the pawl when the disk rotates along the desired rotation direction more quickly than the pawl.

Abstract: To carry out magnetic resonance (MR) tomography, a physiological parameter of an object to be examined is acquired as a function of time to detect a physiological cycle which repeats itself over time. First MR data is acquired for a first region, wherein all points of the first region are arranged in a region of a field of view of an MR system. Acquisition of the first MR data occurs selectively in first time intervals which are synchronized with the physiological cycle and are separated from each other by waiting intervals. Second MR data is acquired for a second region which adjoins the first region. Acquisition of the second MR data occurs in the waiting intervals between the first time intervals.
