  • Patent number: 8393900
    Abstract: A system for aligning a simulator arranged for firing a mounted on a weapon. The simulator has a radiation source arranged so as to emit a beam along a simulation axis, and for adjusting the simulation axis so that it is aligned with the weapon sight. The system includes a sighting mark at which the weapon sight is to be aimed during alignment, and a device arranged in connection with the sighting mark to emit beam along an axis representing an aligned simulation axis. The system further includes an aligning unit that is deployable at the simulator and in which at least a first part of the beam from the element is reflected along an axis representing the current position of the simulation axis.

  • Patent number: 7367805
    Abstract: The invention concerns an aligning device for a simulator (105) arranged for firing and mounted on a weapon. The weapon has aiming means arranged to indicate the aiming of the weapon in a target area. The simulator is equipped with at least a first element arranged so as to emit an electromagnetic beam along a simulation axis, and adjusting means arranged so as to control the simulation axis in order to align the simulating axis with the aiming means. The device is characterized in that it has means (201) arranged so as to reflect visible light from the beam, and sighting means for alignment that are arranged so as to display a projection of the reflected light superimposed over an image (206) of the target area in an alignment sight window. The projected light is movable within the alignment sight window by means of adjusting means so as to enable placement of the projection at a point at which the aiming means are aimed.

  • Patent number: 7250924
    Abstract: A device for tracer stream simulation is disclosed. The device includes a casing having an aperture, a beam splitter, and structure for generating a first image. The aperture is capable of displaying first and second fields of sight. The beam splitter conveys a second image to the first and second fields of sight while superposing the first and second images in the first field of sight. A system for tracer stream simulation is also disclosed and includes a biocular sight with the device being adapted for attachment to the biocular sight. A method for tracer stream simulation in a biocular sight is also disclosed.

  • Publication number: 20040073393
    Abstract: This invention concerns a system for aligning a simulator (3) arranged for firing and mounted on a weapon. The simulator has a radiation source (8) arranged so as to emit a beam along a simulation axis, and adjusting means (10) for adjusting the simulation axis so that it is aligned with the weapon sight. The system is characterized in that it includes a sighting mark at which the weapon sight is to be aimed during alignment, and means arranged in connection with the sighting mark to emit a beam along an axis representing an aligned simulation axis. The system further includes an aligning unit (14) that is deployable at the simulator and in which at least a first part of the beam from the element (8) is reflected along an axis representing the current position of the simulation axis.
