Abstract: The invention relates to an injector body for a fuel injection system, in which the injector body has a substantially cylindrically shaped valve chamber, into which fuel can be introduced at high pressure via an inlet bore, which discharges through an inlet opening in the valve chamber. To compensate for the high local notch tensile stresses in the circumferential direction of the valve chamber, it is proposed that at least in the region of the inlet opening, the valve chamber be provided with bulges, each adjacent the inlet opening in the circumferential direction. These bulges bring about a major compensation for the notch tensile stresses and thus increase the high-pressure strength.

Abstract: An autonomous weapons system simulation is generated on board an aircraft and in flight, displaying virtual scenarios with a simulation of weapons systems on board the aircraft and computer-generated ground-to-air and air-to-air threats. The weapons system simulation system permits a real-time air combat training on board of combat aircraft which is carried out with and/or against computer-generated forces, and the implementation takes place by the integration of the crew in virtual scenarios with virtual partners, targets and enemies in the usual cockpit and display environment.

Abstract: A gearshift device comprises an input unit for receiving input data which is connected via at least one data line to a first controller via which an actuator unit can be controlled for setting a gearbox, especially an automatic gearbox of a motor vehicle, and comprising at least one second controller which is independent of the first controller. The second controller is separate from the first controller and is connected to the input unit via at least one data line. In the case of a fault in the first controller, the actuator unit can be controlled by the second controller at least partially correspondingly to the first controller.
