Abstract: An assembly is for outputting tactile warning signals in a vehicle environment of a vehicle and includes at least one sensor for scanning the vehicle environment and for detecting sensor data, and at least one signal generator for outputting a warning signal that is tactilely and/or haptically perceptible to people in the vehicle environment. The assembly further includes a control device for receiving and evaluating the sensor data and for generating control commands for actuating the signal generator in the event of a person being detected in the vehicle environment.

Abstract: Disclosed is a method for detecting an unsecured load in an especially automatically drivable vehicle by means of a controller, wherein measurement data in the form of lateral accelerations and/or linear accelerations of the vehicle acquired by at least one acceleration sensor are received, a time interval for detecting the unsecured load is started when the measured lateral accelerations or linear accelerations exceed a threshold value, during the time interval started measurement data acquired by at least one sensor are received and derivatives with respect of time of the received measurement data are calculated, an event is counted when the derivatives with respect of time of the measurement data exceed the one threshold value, and the presence of an unsecured load is detected when a minimum number of counted events is reached that are counted during the started time interval.

Abstract: The present invention relates to a method for operating an undulating diaphragm pump comprising an undulating diaphragm and actuating means of the undulating diaphragm electrically powered according to a given frequency or voltage to make the undulating diaphragm oscillate and undulate. According to the invention, the method consists in modifying the electrical supply frequency and/or voltage of the actuating means according to at least one operating parameter, determined in advance, of the undulating diaphragm pump.

Abstract: A method for the circulation of fuel in an aircraft uses at least one diaphragm pump having an undulating diaphragm that can undulate between two flanges, under the action of an actuator, for circulating the fuel between an admission line of the pump and an exhaust line of the pump.
