  • Patent number: 11928203
    Abstract: A method for operating a cooling system of a transformer, wherein the transformer is cooled via a cooling liquid that circulates in the cooling system that includes a heat-exchanger, devices for increasing heat exchange performance of the at heat-exchanger and a controller, where in a normal operating state, the controller adjusts power of the devices for increasing the heat exchange performance as a function of a measured upper temperature and where, irrespective of the measured upper temperature, the controller refrains from activating the devices and/or operates the devices at a reduced power relative to the normal operating state if the lower temperature of the cooling liquid lies below a lower threshold value during operation of the transformer to achieve improved characteristics of the cooling system during operation under low environmental temperatures of the transformer, particularly in the case of a turn-on operation following lengthy storage in a cold state.

  • Patent number: 11652796
    Abstract: A method and edge device for controlling data exchange of an industrial edge device with an industrial automation arrangement and a data cloud, wherein the edge device includes a first communication connection to the industrial automation arrangement and a second communication connection to a network of the data cloud, where the edge device includes applications exchanging data, and where the edge device includes a control device to control the data to be exchanged, wherein whether data exchange of an application is controlled via the first communication connection and the data exchange is implemented directly via the second communication connection or vice versa is defined for each application, where a data flow control device ensures simultaneous direct data exchange by an application via both communication connections does not occur, such that rigorous checking of applications or containers within the applications with respect to data security is not required.

  • Patent number: 11500991
    Abstract: A method and a system for providing security information about an application container for an Industrial Edge device, wherein the application container displays an application, runtime libraries and parts of an execution environment, where first information is obtained from the application or source code, second information is obtained from the application program or source code of the application, where confidentiality classes and processing classes are ascertained, and where the security information is formed by linking arising confidentiality classes to arising processing classes and the security information is associated with the application container such that specific and reliable security information about the application container or applications is generated and the security information is provided to a user or an installation system via association of the security information with the application container or the application to make information about the specific security problems or properties ava

  • Patent number: 8326474
    Abstract: We provide a method for operating a navigation system for a motor vehicle in a road network, and to a navigation system. To this end, first a zone of the road network is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle is associated with at least one emissions class. First, information about the geographical location of the zone and about the emissions class at least required there is stored in the navigation system. Then, information about the at least one emissions class of the motor vehicle is entered into the navigation system. Thereafter, the information entered is considered in the destination guidance process, wherein destination guidance into or through the zone is avoided if the at least one emissions class of the motor vehicle is affected by emissions class-dependent drive-through restrictions in the zone.
