Abstract: A system for transmission of information between at least two players in a training area comprises means on a first (1) of said players for encoding light pulses and means for transmitting information in the form of such coded light pulses towards at least one second (2-4) of said players, said second player having means for receiving said light pulses and means for decoding the information thereof. Each of said players is provided with a clock, and the system comprises means for keeping said clocks synchronized. The encoding means and the decoding means are adapted to utilize data of times of transmission and receipt of said light pulses for transmitting information from the first player to the second player.

Abstract: A shooting target system including a target including a material in which shock waves arise and propagate when hit by a projectile. A first shock sensor is arranged to detect the shock waves. At least a second shock sensor is arranged at a distance from the first shock sensor. A calculation module is configured to determine at least a first time-delay between the detections of the shock wave by the first and the at least second sensor, and to calculate information relating to the point of impact of the projectile in the target based on the at least first time-delay.

Abstract: The invention relates to simulation of tracer fire from a weapon by means of a fire simulation means attached thereon. The proposed method involves projecting a light spot into a visual field of a user of the weapon, such that the light spot is observable by the user when firing a target. The light spot indicates a non-ballistic estimation of a point of impact for a simulated bullet from the weapon. The light spot is turned on at a first point in time (t1) after triggering the simulated bullet (t0) and turned off at a second point in time (t2) after triggering the simulated bullet (t0). A switched-on interval (tON) between the first point in time (t1) and the second point of time (t2) overlaps a laser interval (Tlaser) during which at least one light pulse is transmitted from a fire simulation means to simulate the bullet fired from the weapon.

Abstract: The invention relates to a method and an arrangement for indicating that a target (1), such as a vehicle, has been hit. The target is provided with information on the weapon action, and a light source indicates a hit. The information can be made available by direct electromagnetic transmission, for example via radio, or by means of one or more strips (9–11) with detectors (13) being arranged on the target (1). In the latter case, the detectors detect incident illuminating electromagnetic radiation, and a light source indicates a hit when the incident radiation satisfies defined detection criteria. According to the invention, the light source is mounted directly in one or more strips (12) which in the present case can be the same as the detector strips and consist of distributed light points preferably in the form of light-emitting diodes (14). In this way, a protected and integrated solution is obtained which has little effect on the shape of the target.

Abstract: A protective device to interrupt the flow of current at a work place when current of a magnitude to endanger life flows through the body of a person whereby at least two electrodes with skin contact are applied on a person which electrodes are connected to a voltage sensor which determines the voltage difference between the electrodes when current flows through the body and is designed to release a signal to a circuit breaking device which interrupts the flow of current when the current passing through the body exceeds the admissible value.
