  • Patent number: 12311922
    Abstract: The invention relates to a method for removing user-specific and/or drive-specific user data which are saved distributedly on multiple controllers in a motor vehicle. A trigger apparatus is provided, and the trigger apparatus checks whether a trigger condition has been satisfied. If the trigger condition has been satisfied, a specified common delete command is transmitted to the plurality of controllers of the motor vehicle via a data bus of the motor vehicle, and each controller carries out a specified delete routine if the controller has received the delete command from the data bus, said delete routine being used to overwrite and/or delete user data saved on the particular controller.

  • Patent number: 10243887
    Abstract: A switch unit for an Ethernet network having a switch and a microprocessor, the switch including at least three ports, which are connected to inputs and outputs of the switch unit, a signal detector and generator for detecting and initiating a bus activity being arranged in each case between the ports and the inputs and outputs of the switch unit. For each input and output an allocation rule to the other inputs and outputs of the switch unit is stored in a memory, the switch unit being designed such that when a bus activity is detected at a signal detector and generator, the assigned inputs and outputs of this input and output are read out from the memory and the associated signal detectors and generators are woken up so that they generate a bus activity at their inputs and outputs.

  • Patent number: 10173234
    Abstract: A trigger pump dispenser comprises a body, an outlet nozzle, a pump chamber, a piston for defining a variable volume in the pump chamber, a trigger coupled with the piston by interconnection means, and biasing means for biasing the trigger to a retracted position. The trigger is movable to cause the piston to pump liquid into and out of the pump chamber for dispensing through the outlet nozzle. The piston is interchangeably associatable with the trigger and the pump chamber so that different length pistons are usable to determine different maximum fill volumes of the pump chamber.

  • Patent number: 9632970
    Abstract: An apparatus for operating a data bus system of a motor vehicle having data bus segments, at least one of the data bus segments is designed to switch from an active state to a rest state and vice versa. In a first step, a communication requirement is detected of a first control device of a first data bus segment in the rest state. If a communication requirement of the first control device is detected, the first data bus segment is brought from the rest state into the active state. If a communication requirement of the first control device with a second control device outside of the first data bus segment is detected, all other data bus segments of the data bus system outside of the first data bus segment that are in the rest state are additionally activated across the board.
