  • Patent number: 9574849
    Abstract: A fire-control system including a housing, a light channel, a light source, and a processor. Through the light channel, a user may directly observe a target and receive visually displayed information simultaneously. The light channel includes partially reflective optics and allows for visualization of a reticle to the user via the partially reflective optics. A measure of the distance to the target is also received by the system. The processor is for determining the adequate position of the reticle, based on the distance to the target, and for controlling the light source to emit light so that the reticle is visualized at the adequate position. The light source is an array capable of selectively emitting light in well defined locations on its surface.

  • Patent number: 9303952
    Abstract: A combination sight comprises a magnifying optical sight and a non-magnifying optical sight arranged in parallel. The combination sight is characterized in a switchable component capable of assuming two states so as to deflect a beam path through the combination sight, wherein the first state allows for a user to observe a target through the non-magnifying sight and the second state allows for a user to observe a target through the magnifying sight while keeping an aiming eye static.

  • Patent number: 7764434
    Abstract: A weapon sight of the kind comprising a lens having a partially reflecting surface, a light source spaced from the lens for emitting light towards the reflecting surface to produce a light spot by direct imaging of the light source on the surface to be superimposed on a target when sighting through the lens. For adjustment of the location of the light spot on the reflecting surface when observed from a defined fixed position, the sight includes a device for displacement of the light source, comprising a miniature drive motor or element operatively connected with the light source.
