Abstract: A method of operating an electrolyzer system, including an alkali lye circulating in the system, whereby a lye-related property is determined and further process control is subject to possible change in dependency of an evaluation of the determined property. The property includes the lye concentration which is in particular automatically detected and a lye refilling operation is in particular effected automatically in dependency of the detected concentration, and/or the property includes at least one visually inspectable parameter of the lye and/or lye flow, which is, in particular automatically and in particular during operation of the electrolyzer, detected by visual inspection of the lye/lye flow. An operation condition of the electrolyzer system is determined on the basis of the evaluation.

Abstract: A method for evaluating measurement data that are obtained by a plurality of sensors. The method includes: the measurement data originating from sensors of a first group are processed by a function evaluation module to form a function signal that, when it is supplied to a driving dynamics system of a vehicle, causes the driving dynamics system to carry out a driving task; the measurement data originating from a second group of sensors are processed by at least a first safety evaluation module to form a first safety signal that, when it is supplied to the driving dynamics system, causes the driving dynamics system to prevent a specified undesired event of the vehicle, the second group containing a proper subset of the first group; the function signal is aggregated with the first safety signal to form a control signal that is capable of being outputted to the driving dynamics system.

Abstract: The present invention relates to a welding head (10) for fastening an element made of plastic material to one or more flexible webs (2, 3) made of plastic material, of which a flexible container (1) is composed. The head (10) includes a body made of electrically and/or thermally conductive material having a work surface (15) that is provided for being pressed, during the welding operation, against an element of the unit to be joined. The invention is characterized in that the work surface (15) includes a series of grooves or concave formations (16) that are essentially uniformly distributed on the surface of the work surface (15).

Abstract: A driver assistance system of a vehicle includes: at least one ultrasonic sensor for ascertaining the distance of the vehicle from an obstacle, the sensor being supplied with electrical energy by an onboard electrical system of the vehicle; and an undervoltage detector for detecting an undervoltage in the onboard electrical system, in the event of which the power requirement of the ultrasonic sensor is reduced.

Abstract: An orifice plate assembly for use with a process variable transmitter for measuring flow of a process fluid includes a single piece body having a circumferential support ring. A first face of the circumferential support ring is configured to be sealingly coupled to a first flange of a first process pipe. A second face of the circumferential support ring is configured to be sealingly coupled to a second flange of a second process pipe. A flow plate region is positioned between the first and second pipes and has first and second sides. The flow plate region is concentric with the circumferential support ring. At least one flow orifice in the flow plate region provides a restricted fluid path between the first and second process pipes. A first pressure tap is configured to fluidically couple to the process variable transmitter to the process fluid proximate the first side of the flow plate region.

Abstract: A method providing assistance during the parking maneuver of a vehicle into a parking space situated laterally to the vehicle to be parked, an erroneous length of the parking space being detected with the aid of a sensor system of the vehicle while the vehicle drives past the parking space on a curved trajectory. To determine the actual length of the parking space, a trajectory of the vehicle differing from a straight trajectory of the vehicle is additionally detected while driving past the parking space, for example, on the basis of the steering angle of the vehicle, and a correction value for the detected length of the parking space is ascertained therefrom. The actual length of the parking space is determined with a high degree of accuracy without the need for other measured values to be detected, for example, the orientation of parked vehicles or the depth of the parking space.

Abstract: In a method for operating a parking aid system for a vehicle having a plurality of distance sensors each sensing the near range of the vehicle, and having at least one path sensor sensing a path traveled by the vehicle, the distance sensors are operable in a first mode for the parking space measurement, and the distance sensors are operable in at least one further mode in which they are used as parking aid in order to avoid collisions. The distance sensors are temporally activated using different transmit sequences in the two modes, a switchover between the different transmit sequences being implemented as a function of the movement of the vehicle.

Abstract: A sensor transmitter device for transmitting the payload data of a sensor to a bus control device is described, the sensor transmitter device being connectable to a data bus of a vehicle, which is configured for simultaneous transmission of bus data packets between a plurality of sensor transmitter devices and a bus control device.
