Abstract: The invention relates to a stirrer organ (1) in composite construction comprised of a metallic part (4) and a hybrid casting (9), with the hybrid casting (9) being fixed to the metallic part (4) by means of at least one anchoring element which forms at least one back-cutting in the hybrid casting (9). Furthermore, the present invention relates to a method for rehabilitating a damaged metallic stirrer organ which when applied provides a rehabilitated stirrer organ (1) in composite construction. The invention tackles the task of creating a stirrer organ (1) in hybrid construction which features a largest possible metallic part (4) because higher strength can hereby be achieved. This task is inventively solved in that the anchoring element is provided with a perforated plate (5) which is spot-wise fastened to the metallic part (4) and which is arranged at least partly at a small distance to the surface of the metallic part (4) so as to configure the at least one back-cutting.

Abstract: According to one embodiment of the present invention, a method of determining the depth profile of a surface structure includes: irradiating the surface structure with irradiation light including light components of different wavelengths; and determining the depth profile of the surface structure in dependence on interferometric effects caused by the reflection of the irradiation light at the surface structure.

Abstract: The invention relates to a method for the controlled application of a stator-current target value (ISnom) and a torque target value (Mnom) for a polyphase machine (4) that is supplied by an electronic power converter.

Abstract: A parachute control system is actuated primarily by drogue parachute drag force. Drag force is used as a proxy for vehicle airspeed. The control system uses altitude and force sensors combined with a chronograph to determine the state of a deployed drogue parachute. It then compares the sensed condition with a condition defined by preset altitude, force, and time values. Once both altitude and drogue parachute drag force are below certain maximum values and within pre-determined time windows, an event trigger signal is generated.

Abstract: Methods and apparatus, including computer systems and program products implementing a messaging protocol. The messaging protocol may be a messaging protocol for transporting a message across a messaging landscape in a collaborative network. Techniques include sending a message that is defined to include a structured message header with information related to at least one component from a set of components defined by a protocol, including protocol version information in a message such that a component of a messaging landscape can interpret the message based on the version information, defining a message as one of a class of messages, end-to-end acknowledgement for messages, and security for headers and payloads of messages.

Abstract: A device having an electromagnetic actuator for actuating a control element, in particular a charge cycle valve of an internal combustion engine. The actuator includes at least one elastic element, for example, a valve spring, provided for the purpose of elastic deformation. The elastic element is connected to a deformation sensor providing a signal making it possible to determine the deformation of the elastic element, and to determine the position of the control element.

Abstract: The invention relates to A method for determining a rotational velocity of a transducerless polyphase machine that is operated in a field-oriented manner, a stator-current model space vector and a conjugate complex reference space vector being calculated using a complete machine model, and the torques-active and dummy variables being measured from these model space vectors and from the measured stator-current actual space vector, from which active and dummy variables, in each case, a system deviation is determined. These measured system deviations are weighted and finally totaled, this total system deviation being used for adjusting the model rotor angular velocity such that the total system deviation becomes zero. Thus a method for determining the rotational velocity of a transducerless polyphase machine that is operated in a field-oriented manner is possible, breakdown protection being assured.
