Abstract: Device and method for positioning of a moving object in a monitorable region using a stationary monitoring system and a transponder attached to the moving object. Furthermore, the monitoring system contains at least two sensor units and an analysis unit, which allow distance values (Dx) to be established using travel time measurement of ultrasound signals (US) and positioning to be performed therefrom.

Abstract: A radiation reflecting element (34), more particularly a so-called triple prism or a retro-reflector, is provided with a photonic element on a surface serving either for the passage of an electromagnetic energy beam (light) (40,43) or on one of the surfaces (30–32) serving for the deflection of the beam. The photonic element is characterized by the presence of a photonic band gap (5,7) capable of being shifted e.g. by an electric signal. Thus, with an appropriate selection of the wavelength of the light beam, the photonic element can be switched from reflective to transmissive, thereby allowing a modulation of the light beam with a high modulation depth.

Abstract: The interrogation device is used for identifying a target device. A transmitter is designed for transmitting a coded electromagnetic radiation. The target device has sensor means for detecting this radiation and for converting it into electrical signals, which are supplied to an evaluation unit, as well as transmitting means which, in accordance with decisions made by the evaluation unit, return messages to receiving means located inside or outside of the transmitter. The transmitter comprises a circuit with an oscillator and an antenna, which are designed to generate individual pulses, or short bursts of pulses in the giga-frequency range, which are chronologically modulated. A coded information signal is obtained from these pulses.

Abstract: The detonation of e.g. a grenade or another explosive body is simulated by the evaporation of a liquid and subsequent ejection through a nozzle 17, thereby forming a cloud of vapor at the location of the detonation. The device includes an evaporator 10 heated e.g. by combustion means. The heating system 14 is designed to produce the heat for a continuous evaporation of a liquid in the evaporator. The liquid is preferably a mixture of ethylene glycol in water. It is thereby possible to simplify the handling and application and to reduce the danger potential.

Abstract: Detonating projectiles are fired into a target area by a weapon, the time between firing and detonation being one second or less. By setting the target location at the same distance as e.g. the edge (1) of a building (3), however laterally displaced with respect to that edge, it is possible to obtain an effect also in an area invisible to the bearer of the weapon. For simulating this weapon, for example in house-to-house fighting, it is proposed to affix devices (5) comprising a sensor (22) and a transmitter (27) to obstacles. When the weapon is fired, a simulation device provided on the weapon transmits a firing signal to the sensor (22), the latter activating the transmitter (27). Similarly to the real effect of the weapon, the transmitter (27) emits an impact signal in the impact area (7) which also includes the mentioned area which is invisible to the bearer of the weapon.
