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.

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.

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. According to the invention: current components (ISdnom, ISqnom) in a co-ordinate system (d, q) with a fixed rotor flux or rotating magnetic pole are calculated in accordance with a torque target value and in asynchronous machines in accordance with a rotor-flux target value (ψRnom), a calculated rotor-flux actual value (ψ R ) or a rotating magnetic-pole flux; a stator-circuit frequency (ω S ) is determined; a terminal-flux target value (ψKnom) is calculated in accordance with the values (ISnom, ISqnom, ψ R , ω S ) by means of the machine parameters (L, R S ), said terminal-flux target value being subsequently projected onto a flux-course curve, selected from stored, off-line optimised flux-course curves. This permits the state of the stator current (I S ) to be regulated in relation to the rotor flux (ψ R ) or rotating magnetic-pole flux by means of momentary values, facilitating a stationary and dynamic precise control of motor currents (I1,I2,I3) and thus the torques (M) of a polyphase machine (4).

摘要:
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.
