Abstract: A weapon system which may be carried by a person, including a weapon having a weapon barrel, a muzzle brake, a cartridge holder connected at a rear end of the barrel, a base part removably attached to the cartridge holder, and having a lock with an ignition device and a nozzle, a recoil brake mounted around the barrel, a weapon structure or weapon housing, a firing control operative to permit target assignment and an electrical communication interface between the person and the firing control.

Abstract: A method of tracking a target (2) moving in an airspace and a target tracking system (10) for performing the method are described. A search sensor (12) searches a search space at a first clock rate (2&pgr;/&Dgr;T1) and establishes target information in regard to a track (4) flown through by the target (2). Calculation means (16) extrapolate an expected flight path (6) from the target information established and provide flight path data, which describes the expected flight path (8), to a tracking sensor (14), which covers a tracking space (15), and provides this data at a second clock rate (2&pgr;/&Dgr;T2), which is higher than the first clock rate (2&pgr;/&Dgr;T1). When the target (2) reaches the tracking space (15), the tracking sensor (14) is aimed at the expected flight path (6) on the basis of the flight path data provided, the target (2) is detected as soon as it is detectable by the tracking sensor (14), and the tracking sensor (14) is tracked on the target autonomously.

Abstract: A system for securely storing secret information comprises an apparatus (10; 1) containing the secret information, a device meant to use said secret information to decrypt a digital content and a remote server (20). The apparatus can send the secret information to the server (20) that has means for storing the secret information. A process with the following steps is proposed: initiating a remote communication between the apparatus (10; 1) and the remote server (20); sending the secret information from the apparatus (10; 1) to the server (20); storing the secret information on the server (20). A method for distribution of a digital content is also described.

Abstract: An ammunition container, especially a drum magazine, is subdivided by side walls into a plurality of sector-shaped compartments. Within the ammunition container there is located a cartridge belt, and protruding into each compartment is a loop of such cartridge belt. Each loop of the cartridge belt consists of two loop portions which bear against the side walls of the drum magazine. By means of magnets, located between the side walls of the drum magazine and the loop portions of the cartridge belt, the cartridges are secured against unintentional shifting.
