  • Patent number: 12316476
    Abstract: Embodiments relate to a system for transmitting data in a motor vehicle. A central electronic control unit comprises at least one LIN master, and at least one local controller, which is coupled to the central controller by means of a first data connection. The local controller is additionally coupled to a LIN bus, which is paired with the LIN master and to which at least one LIN slave is connected. The data transmission speed of the first data connection between the central controller and the local controller is faster than the data transmission speed of the LIN bus. Methods for actuating a LIN slave connected to a LIN bus and to a motor vehicle are also provided.

  • Patent number: 10823188
    Abstract: An electric centrifugal pump having a motor housing, a pump head, a containment shell, and a rotor assembly consisting of a pump impeller and a permanent magnet rotor, wherein the pump head with the containment shell defines a wet chamber, in which the rotor assembly is arranged rotationally around a longitudinal motor axis, the containment shell with the motor housing defines a dry chamber, in which a wound stator is arranged, and the permanent magnet rotor is arranged within the stator and a hollow-cylindrical region of the containment shell. Particle accumulations in the region between the containment shell and the permanent magnet rotor cannot occur or can only occur to a very minor extent and that the consequences of impurities in the wet chamber are reduced in order to prevent premature wear or a blockage of the centrifugal pump.

  • Patent number: 10200290
    Abstract: A method for operating a station for serial data transmission using data frames in a communication network, configured to perform a carrier sense multiple access with collision avoidance (CSMA/CA) method, includes performing a first priority resolution for a specific first data frame to be transmitted on a communication channel, and establishing whether the specific first data frame to be transmitted has a highest priority. The method also includes performing a first backoff if the specific first data frame has the highest priority, transmitting the specific first data frame if the communication channel is free after the backoff, and raising the priority of the specific first data frame, in the absence of acknowledgement of the transmission of the specific data frame, to a priority level that is used exclusively for untransmitted data frames.
