An embodiment of an apparatus for determining the attitude angles of a weapon includes a number of accelerometers for measuring the components of the acceleration of the weapon along the axes of a first reference system integral with weapon; a number of gyroscopes configured in such a way to measure the components of the angular speed of the weapon along the axes of the reference body; and a processing unit configured to compute a number of actual attitude angles of the weapon under dynamic conditions based on the components of the angular speed; determine a number of static attitude angles of the weapon under static conditions of the weapon based on the components of the acceleration; and correct the components of angular speed according to static attitude angles and to the actual attitude angles.

A target device is usable with a simulation system which includes a weapon simulator having a trigger, a chamber for firing a blank cartridge in response to the trigger, and a transmitter arranged to emit a light signal defining one or more activation codes of prescribed duration in response to the trigger. The target device includes a sensor array of photodiodes and a processor receiving output signals from the photodiodes. The processor determines that the sensor array has been hit by the weapon simulator in response to a first portion of one activation code being received by one of the photodiodes and at least one second portion of the same activation code being received by the same or a different one of the photodiodes when the first portion and the at least one second portion correspond to an entirety of one activation code within the respective prescribed duration.

A spring whip which defines a defensive weapon for emergency use to disarm an attacker carrying and intending to use a knife, gun or any other type of offensive weapon, the spring whip having a hollow housing serving as a hand grip and providing an internal storage compartment for receiving plural lengths of helically wound springs, the springs being of sequentially increasing larger diameter size. The springs are operatively arranged relative to each other about a common axis so as to be maneuverable between a telescoped stored position within the housing compartment and an extended whipping position extending from one end of the housing. The lengths of springs are alternately wound in opposing clockwise and counter clockwise directions to facilitate moving between the telescoped stored position and the extended position, and also to permit threading together of adjacent sections, to thereby securely lock them in place in the extended position.

A personal security apparatus to house weapons, valuables, and/or items requiring concealment includes a lockable insert mechanism to securely house items and at least one receiving apparatus adapted to mount the insert mechanism into or onto various structures and a lockable access door that provides convenient, rapid access to the items contained in the personal security apparatus and further prevents access by unauthorized persons.

The invention relates to a method of with a projectile (1) comprising a reactive charge (4), combating an explosive-charged weapon unit (7), preferably an enemy shell, so that undesirable harmful effects on the environment are reduced, wherein the projectile (1) is configured to penetrate the surface (8) of the weapon unit (7) upon impact so that a passage (9) is opened into the explosive (10) of the weapon unit (7), through which passage (9) the reactive charge (4), under the influence of the kinetic energy of the projectile (1), is transferred to the explosive (10) of the weapon unit (7). The method can be deemed to be characterized in that the reactive charge (4), upon contact with the explosive (10) of the weapon unit (7), reacts and starts a hypergolic reaction with the explosive (10). The invention also relates to a projectile (1) for the said method.

A munition is described including a reactive fragment having an energetic material dispersed in a metallic binder material. A method is also described including forming a energetic material; combining the energetic material with a metallic binder material to form a mixture; and shaping the mixture to form a reactive fragment. The munition may be in the form of a warhead, and the reactive fragment may be contained within a casing of the warhead.
