Abstract: A laser weapon system includes a chamber configured to direct a post-detonation gas flow between a first mirror and a second mirror, and an ejectable ammunition cartridge containing a first gas and a second gas. The cartridge is fluidly connected to the chamber.

Abstract: A laser sighting device for a semi-automatic handgun having a recoil spring guide chamber housing a recoil spring surrounding a spring guide. The laser sighting device includes a pulse modulated laser received within the spring guide, having an input and a light output for emitting a pulse modulated laser light aligned with a path of a bullet fired by the handgun; and a sensor for detecting firing of the handgun, having an output coupled to the input of the pulse modulated laser. When the sensor detects the handgun has been fired, the output of the sensor triggers the pulse modulated laser to emit a train of pulses of laser light.

Abstract: A laser sight is embedded in a mounting rail otherwise used for attaching accessories to small arms discharge devices such as pistols or rifles. The mounting rail has a transverse profile that extends along an axis of the mounting rail for engaging mating features of the accessories. The laser sight is located at least partly within the transverse profile of the mounting rail and has a sighting axis that extends substantially parallel to the axis of the mounting rail.

Abstract: A sight assembly for a firearm includes a foregrip removably attachable to the firearm, a first light source disposed within the foregrip, and a different second light source disposed within the foregrip. The assembly also includes a power source electrically connected to the first and second light sources, and a control circuit configured to control activation of the first and second light sources.

Abstract: A mounting rail assembly is provided for firearms, wherein the assembly includes a mounting rail, an electrical input contact, an electrical output contact and an embedded conductor electrically connecting the input contact and the output contact. Control circuitry can be embedded within the mounting rail to provide for data and power transmission at the electrical contacts. The mounting rail assembly can be integrated into a firearm, or can include a receptor channel for cooperatively engaging an existing mounting rail of the firearm.

Abstract: A handheld target marker is provided, wherein the target marker includes a housing retaining a gas laser, a collimating or focusing lens, a driver and a power supply. The laser produces a thermal infrared beam which can be selectively directed to impinge upon a target. The impinging beam is viewable by a thermal imager. The handheld target marker operates at ambient temperatures and incorporates the driver and power supply necessary for operation of the laser, wherein the beam can be pulsed for enhancing imaging on the thermal imager.

Abstract: A sight assembly removably attachable to a firearm includes a foregrip, a quantum cascade laser disposed within the foregrip, and a power source operably connected to the quantum cascade laser.

Abstract: A head up display for firearms is provided, wherein a light valve is employed to create variable images in response to user input. The images from the light valve are entrained in an illuminating beam which intersects a diffractive optic. The diffractive optic includes a recorded infinite focal plane which is reconstructed by the illuminating beam, thereby displaying the image from the light valve at an infinite focal plane which is readily viewed be a user looking through the diffractive optic.

Abstract: A firearm system includes a foregrip removably mountable to a firearm, the foregrip having a programmable button controlling at least one of an accessory of the firearm and a component of the foregrip.

Abstract: A magazine tube and barrel clamp with integral target illuminator, wherein a laser module can be incorporated is provided for a firearm having a magazine tube and a barrel. The frame defines a clamping sleeve for substantially encircling the magazine tube and a barrel receiving channel for receiving a diameter of the barrel, wherein the magazine tube and the barrel are thus fixed in a predetermined spacing. The frame further defines an illuminator recess for receiving a substantial portion of a reflector in the target illuminator, thereby shielding the target illuminator from contact with external surfaces. A driver circuit is retained within the frame to selectively operate the target illuminator and a laser sight, wherein the target illuminator can be a solid-state light emitting device.

Abstract: The flexible prism is comprised of two thin, rigid, optically transparent plates sandwiching an optically transparent deformable material such as a transparent liquid or a transparent flexible solid. The index of refraction for all of the materials is preferably matched, such that reflections between interfaces are minimized. The liquid/flexible material used in this flexible prism may consist of almost any substantially transparent material that is not rigid like a solid glass. The angles of one or both of the rigid surfaces of the flexible prism can be selectively adjusted with a respect to a spectrally narrow beam of light passing through the prism so as to produce the refraction desired.
