Abstract: A voltage converter is designed to convert an alternating input voltage into a direct output voltage. The voltage converter includes a first sub-converter having a first switch half-bridge, which is coupled to a first pole of the input voltage by a first main coil, and a second sub-converter having a second switch half-bridge, which is coupled to the first pole of the input voltage by a second main coil. In addition, the voltage converter includes a diode half-bridge, which is jointly used by the first sub-converter and the second sub-converter. The voltage converter has a first return coil and a second return coil, which couple a center point of the diode half-bridge to a second pole of the input voltage. The first and second main coils and the first and second return coils form a coupled choke, the coupled choke having a choke core.

Abstract: In a method for checking an at least semi-autonomous driving mode of a vehicle, intervention data are provided by a plurality of vehicles. The intervention data each represent a human intervention in an at least semi-autonomous driving mode of a vehicle. The intervention data includes sensor data at the time of the intervention and position data for a position at the time of the intervention. In accordance with the intervention data from the plurality of vehicles, a position is determined at which an increased number of vehicles registered a human intervention.

Abstract: A method for producing a stator includes: providing a main body, the main body having: a cavity for accommodating a rotor, and a plurality of slots, extending axially through the main body, the plurality of slots accommodating electrical conductors of a winding, providing slot insulation so as to ensure that a slot interior of each slot of the plurality of slots is electrically insulated from the main body and is fluidtight; and forming a respective end plate on each of two ends of the main body, the end plates being attached in a fluidtight manner to the main body so as to ensure that no fluid can get between the end plate and the main body and reach the cavity of the main body. Each end plate has a radial part and an axial part, and the axial part has an insert.

Abstract: A cleaning chemical assembly has a collection container, a pump, two ports for storage containers that contain the same cleaning chemical, and a switchover valve that can be switched between a first state, in which the pump can pump liquid from the collection container to the storage container connected to the first one of the two ports while the second port is disconnected in a liquid-tight manner, and a second state, in which the pump can pump liquid from the collection container to the storage container connected to the second one of the two ports while the first port is disconnected in a liquid-tight manner. A sensor is provided that can be used to detect whether one of the storage containers is empty.

Abstract: A display device for the interior of a vehicle includes: (i) a display unit, which is designed for optical display of information and has a display element for this purpose and which can be or is arranged in a longitudinal extension direction of the vehicle behind a front row of seats, preferably on a roof lining of the vehicle; (ii) a movement unit, which is designed to move the display unit, in particular with the display element pivoted away from the roof lining of the vehicle, in the longitudinal extension direction, in particular controllably, between various working positions and/or to hold the display unit in a given working position; and (iii) a control unit which is designed to control the movement unit in such a way that the display unit and the display element are arranged at a predetermined first distance or first distance range from an element of the front row of seats.

Abstract: Over the past several decades, rapid advances in semiconductors, automation, and control systems have resulted in the adoption of programmable logic controllers (PLCs) in an immense variety of environments. A synchronization system coordinates storage, retrieval, and activation of engineering object models among local and remote nodes. The synchronization system facilitates local and remote design and development access to the PLCs, as well as continued correct operation of the PLCs.

Abstract: A workpiece data processing method and apparatus are for accurately determining a relationship between production equipment processing parameters/ambient condition data and workpiece quality inspection results.

Abstract: A method for registering a total station, which is deployed in a measurement environment with one or more objects, in the reference system of a computer-aided design (CAD) model, which images the one or more objects of the measurement environment, includes registering the total station by a control device.

Abstract: A method for preventing stalling of an internal combustion engine of a motor vehicle, wherein the motor vehicle has at least one internal combustion engine, at least one automatically controlled clutch, and at least one transmission, wherein a drive shaft of the internal combustion engine can be coupled to a transmission input shaft of the transmission by means of the clutch to transmit torque, wherein the clutch is disengaged if a calculated rotational speed value of the drive shaft is less than a certain threshold value, and wherein the rotational speed value is calculated, in particular continually or continuously, as a function of a determined, current rotational speed of the drive shaft and as a function of a determined, current speed gradient of the drive shaft.

Abstract: A dialog system and intelligent personal assistant capable of semantic-understanding mapping between user intents and machine services includes an interface to receive a voice or text request from a user. Semantics of the request including at least one of entities, intent, or context are extracted from the user's request. A sequence of action features is selected based on the extracted semantics. A sequence of application programming interfaces (APIs) corresponding to the sequence of action features is then executed to generate a result. An action sequence optimizer may optimize the sequence of action features based on user configuration. The examples provide a technical solution to model a richer semantic-understanding mapping between user intents and available APIs, that will be greatly improving user experience in the spoken dialogue system, as core of personal assistant.
