Abstract: A multimedia distribution network, useful on board a passenger aircraft, includes a first network node configured as a head controller, a plurality of second network nodes configured as intermediate controllers connected to the first network node, and a plurality of third network nodes configured as end device controllers, each connected to one of the second network nodes. The head controller is configured to transmit a multicast stream of multimedia control signal packets to control the end device controllers to the intermediate controllers. The intermediate controllers are configured to periodically transmit unicast delay queries to the head controller, to process the received multimedia control signal packets to the end device controllers and to distribute processed multimedia control signal packets with a controllable delay based on the content of unicast delay indicator signals sent by the head controller to the intermediate controllers in response to the unicast delay queries.

Abstract: A flight condition determination device, in particular for autonomous use in an aircraft without connection to avionics systems, includes a housing, a triaxial acceleration sensor installed in the housing, a processor, which is coupled to the triaxial acceleration sensor and installed in the housing, a working memory coupled to the processor, and a power supply unit integrated in the housing, having a power supply socket, via which the flight condition determination device is connectable to an electrical energy supply source of an aircraft. The processor is configured to evaluate acceleration values continuously received from the triaxial acceleration sensor and to determine a flight condition signal from the evaluated acceleration values.

Abstract: A hydraulic valve, in particular a hydraulic transmission valve including a magnetizable housing which envelops a magnet coil at an outer circumference and at least at one face of the magnet coil; a pole cap arranged in an interior of the housing, wherein the pole cap includes a pole core and a pole tube arranged in an axial sequence towards a face of the magnet coil, wherein the pole core and the pole tube are integrally connected in one piece by a connection bar, wherein the pole core is connected with the connection bar by a pole core cone and/or the pole tube is connected with the connection bar by a pole tube cone, and wherein the pole tube includes an end that is closed with a termination plate at a face of the pole tube that is oriented away from the connection bar.
