Abstract: Disclosed are a method and a device for supplying electrical power for two or more technical systems, which are connected to an electrical supply line with a feed point, arranged in a connecting rod, and for data transmission between the feed point and the technical systems, supplying power to the technical systems is done with essentially constant current intensity. Data transmission from the feed point to the technical systems is done by modulating the current intensity, and data transmission from the technical systems to the feed point is done by modulating the voltage.

The present invention additionally relates to new crystal forms of the compound of the formula I.

Abstract: A system for detecting a man-overboard event, comprising a plurality of first computing units having at least one optical sensor with a predetermined detection range and a second computing unit connected to the plurality of computing units, characterized in that each first computing unit is designed, independently of the others, to evaluate the data sensed by the at least one optical sensor of the respective first computing unit to determine whether a man-overboard event is present on the basis of these data and, when a man-overboard event (event) is present, to report this to the second computing unit, wherein the second computing unit is designed to output an alarm and/or a control command to carry out a man-overboard manoeuvre.

Abstract: The present invention relates to a novel process for preparing substituted cyclohexane amino acid esters and spiroketal-substituted cyclic keto-enols, and to novel intermediates or starting compounds that are passed through or used in the process according to the invention.

Abstract: An arrangement for connecting different parts includes two vehicle components. The vehicle body components include a first vehicle body component taking the form of a sheet metal component with a joining flange and being connected at this joining flange to the second vehicle body component via a welded connection. The joining flange on the first vehicle body component has a turned-over rim and is thereby formed with a doubled sheet metal thickness.
