Abstract: The invention relates to a reflector comprising a reflector cavity (110) having a front opening for receiving EMR into the reflector cavity (110) for subsequent reflection of the EMR by at least one reflector element (120) arranged within the reflector cavity (110), characterized in that the reflector further comprises a front cover (130) that has high EM R transmittance in at least parts of the EM spectrum, the front cover (130) being arranged to cover the front opening of the reflector cavity (110), and that the front cover (130) and front opening form a gastight seal (140) impermeable to gas to prevent transport of material into and out of the reflector cavity (110) through the front opening.

Abstract: A wireless target system unit for a weapon effect simulation system. A radio transmitter and receiver communicates with a control system. A laser receiver is arranged for receiving laser light from an attacking system. The wireless target system unit includes two retro-reflecting prisms arranged to retro-reflect an incident laser light from an attacking system. Each reflecting center of the retro-reflecting prisms and a sensor center of the laser receiver are mounted such that they form an isosceles triangle. The distance between the reflecting center of each retro-reflecting prism and the sensor center of the laser receiver are equal.

Abstract: An AMPG device for generation of electrical energy, including a bobbin, at least one magnet, and at least one spring member. The magnet is arranged to be movable together with the spring member. The device is arranged so that when exposed to an acceleration component in a possible path of mobility of the first magnet, the first magnet will, due to its association with the spring member, move in an oscillating manner in relation to the bobbin, so as to generate electrical energy. The device is arranged to at a limiting position of the mobile magnet's path of mobility a spring member with an equal or higher spring constant than the remainder portions of the magnet's mobile path acting on the magnet. An AMPG device assembly includes several AMPG devices. A method to optimize the electrical output of the device adapts the device to the frequencies appearing in the application where it shall be used.

Abstract: This invention concerns a device for a weapon sight. The device includes a deflecting element (15) disposed in an optical path through the sight and comprising an optical wedge (17), and means (16) arranged to control the positional setting of the optical wedge to produce a randomly altered sight image in the sight. The device is characterized in that the control means (16) are arranged to produce, before firing, the altered sight image and, during firing, to guide the wedge or wedges to a reference position in which the sight image is unaltered. The invention also concerns a method for optically simulating recoil in a weapon with a sight.
