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.

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: An acoustic support system comprising a number of mobile units each including a electronic control unit, a memory for data representing acoustic signals, a reception unit for receiving control data, a transformation unit for transforming the part of data selected by the control unit from the data stored in the memory into acoustic signals, and a sound unit for playing back the acoustic signals. Further it is provided for a central unit including a control unit for generating control data and a broadcasting unit for transmitting control data to selected mobile units. The mobile units with the acoustic signals stored therein can individually be selected and controlled to allow realistic acoustic simulation of events. The system is easy to handle and can be used repeatedly and has a low price.

Abstract: A simulator for front-loaded barrel weapons, e.g. a mine thrower simulator, is provided with an outlet opening at the lower end of the launcher tube through which the shots, e.g. grenades, exit the launcher tube, thus allowing realistic training conditions. Both the ammunition and the simulator preferably comprise sensors and controls which collect the data from the sensors and perform a first evaluation. The results are transmitted to a computer in the custody of the trainer, which delivers the final evaluation and the calculation of the point of impact, inter alia.

Abstract: The invention relates to an interferometer head with a rigid bearer or casing to which a beam divider for the spatial division of laser light into a measuring and a reference beam and at least one recombination device are firmly secured (adhesively), where a reference beam guided by a reference path in the interferometer head and a measuring beam or part thereof guided by a movable measuring mirror of reflective measuring surface interfere to form at least one optical interference signal.

Abstract: The invention concerns a device for generating light, in particular light for use in length measurement using an interferometer. The frequency of the laser light emitted is controlled as a function of the wavelength in the surrounding gaseous medium (air) in such a way that the wavelength in the air remains constant. The light source in this device is a laser diode. Located external to the laser resonator is a device for feeding back to the resonator, at selected frequencies, light emitted by the laser diode.

Abstract: A sliding gauge for measuring animal carcasses for slaughter, tree trunks, whole cheese or other objects. The sliding gauge includes a rod and a slide mounted for sliding movement on the rod by a form-locking guide arrangement. The rod and the slide are each equipped with a jaw projecting therefrom at a right angle, such that the jaws are parallel. Longitudinal markings and at least one length sensor are included with the rod and slide. A force sensor on one of the jaws may operate to disable further operation of the length sensor such that repeatable measurements may be made of soft or elastic articles. The length sensor is connected to electronic circuit components, which may include a microcomputer, for evaluation and processing of the signals supplied by the length sensor.
