Abstract: A firing weapon is associated with a laser radiation source mounted in proximity to the weapon and also with a detector which is sensitive to the laser radiation. The orientation of the radiation is adjusted independently of the aiming of the weapon in order to carry out continuous detection of the target as a result of detection of radiation by the detector after reflection from the target. The orientation and the time of transit of radiation between source and target are utilized in order to obtain target data relating to position in elevation and in azimuth as well as distance of the target. The data are processed in order to orient a real shot or in order to compare the data quantitatively with the position of a simulated projectile which follows a fictitious trajectory.

Abstract: The invention relates to a movement detector, more particularly a sensor comprising a container partially filled with a liquid into which three electrodes extend. An input alternating signal is applied to two of the electrodes and an output signal amplitude modulated in accordance with movement of the liquid in the container, is detected from another two of the electrodes by means of a sensing circuit which includes a demodulator for detecting the amplitude modulation and a circuit arrangement which provides a container movement signal in response to successive peaks in the demodulated signal which are in excess of a given threshold value being spaced apart in time from one another by a time dependent upon the peak magnitudes of the demodulated signal.

Abstract: An individual monitoring device is carried by a person whose movements are to be monitored. The monitoring device comprises a displacement detector arranged to supply a continuously variable signal dependent on the positional changes of the device, signal processing circuit receiving the signal and at least one alarm device operatively connected to the signal processing circuit to provide an alarm in the absence for longer than a predetermined time of a signal due to the monitored person's "normal" movements. The signal processing means comprises a band pass filter for receiving the signal supplied by the displacement detector. The pass band of the filter only allows signals to pass which are due to changes in position of the device consequent upon the monitored person's normal movement.

Abstract: The invention is concerned with the techniques of firing simulation. Its main subject is a method of and device for firing training, in which optical simulation of firing as a function of at least the firer's aim and of reference data comprising at least a reference line of sight and a target distance, is characterized by the fact that account is taken in the simulation of prerecorded terrain data defining at least three ground planes perpendicular to the line of sight, vertical plane containing the said three ground planes being located around the target, in front of the target, and behind the target, with respect to the firer.
