The near infrared region is marked by near infrared emitting photodiodes encased in a hardened polymeric molding compound. These diodes are only visible through night vision devices (image intensifiers). The middle through the far infrared regions are marked by the heat generated from the combustion of the pyrotechnic smoke generant. The smoke generant is housed in a canister having a highly emissive surface. The radar region is marked using radar chaff. The target marker is configured for use with conventional mortar or rocket delivered flare systems.

Abstract: A light emitting module is attached to one of a pair of separable U-shaped metal clamps that can fit around a weapon trigger guard. The clamps have recesses for retaining elastomeric inserts which contact the trigger guard. The inserts are of inexpensive glass-filled molded plastic rather than machined steel so that a greater variety can be provided at low cost and little value is lost by discarding those not needed for a particular weapon. The greater variety provides a better fit with little or no custom shaping and the elastomeric inserts are much easier to shape if an unusually contoured trigger guard is encountered. A slide switch passes through the clamp and is actuated by either a right or left handed user. The motion of the switch is transverse to the trigger guard and firing direction of the gun.

Abstract: A firearm sighting device is disclosed that prevents dominant eye crossover and ensures proper shoulder placement of the firearm for increased accuracy. The sighting device includes an elongated housing having an opening at one end, and a light source is disposed in the housing oppositely from the open end. The housing is adapted to be mounted on the barrel of a firearm with the opening directed toward the butt end portion of the firearm and with the light source near the muzzle end. The housing has a diameter and length sufficient to prevent the shooter's non-aiming eye from seeing the light source, so dominant eye crossover is prevented. The diameter of the housing also prevents the shooter's aiming eye from seeing the light source unless the aiming eye is properly aligned with the barrel, so the sighting device ensures that the firearm has been properly shouldered.

Abstract: A reticle gunsight is illuminated by a chemical illumination stick which is nserted through a tapped port in a lower chamber of the gunsight. The tapped port is closed with a threaded plug to retain light within the lower chamber. The lower chamber has an optical opening therein which is aligned with reticle cross hairs to produce a light beam having the image of the cross hairs. The light beam is focussed through a collimated lens and then directed by a prism onto a beam splitter in an upper chamber of the reticle gunsight. The upper chamber is open at both ends and is aligned with the barrel of the gun so that when the image of the target is superimposed with the image of the reticle in the beam splitter, the person using the gun knows that the gun is aimed at the target. Since the gunsight does not rely on electrical illumination and does not itself illuminate the target, many deficiencies associated with previous gunsight configurations are eliminated.

Abstract: A sight apparatus is formed of a small housing having a curved top and an internally disposed chamber which is intended to be positioned generally at the location of a normal front sight as used with firearms intended for shooting remote targets. The housing incorporates a switchable light emitter such as an LED of substantial brightness which is positioned adjacent a small collimation portion and exit aperture pointed parallel with the gun barrel axis toward the shooter's eye station. The brightness of this emitter output is selected with respect to the brightness of the ambient suround about the target so as to achieve enhanced brightness contour via physiological lateral inhibition within the shooter's eye. There then results a sharp sighting image which represents gun tip positional data to the shooter. This data is available to the shooter even though both eyes are focused at the remote field of the target, generally at infinity, and defocused at the tip of the gun barrel.

Abstract: The laser generator (20) is mounted in a sleeve (13) in such a way that its barrel (22) is held by three support elements (25,25',30) two of which consist of a sliding part (25,25') having a bearing surface (24,24') extending in an oblique plane with respect to the axial plane which is perpendicular to the radial direction of the support element in question, while the oblique bearing surface (24,24') of each sliding part coacts with a rib (23) projecting from the outer surface of the barrel (22) of said laser generator (20). The side of the sliding part (25,25'), which is opposite the above mentioned bearing surface having a thread (26,26'), engages a thread formed on the inner surface of a ring (28,29) so that the rotation of the ring (28,29) moves the sliding part (25,25') along the axis of the sleeve (13) in a direction parallel thereto, while the above mentioned oblique bearing surface (24,24') moves the axis of the laser generator barrel (22) in a direction parallel to the radial direction in question.

Abstract: An inspection device for evaluating the inside surface of a barrel of a firearm is disclosed. The inspection device comprises a casing, a lightbulb and battery contained within the casing, and a light diffusion assembly. The light diffusion assembly includes an annular portion connected to one end of the casing through which light may pass, and an opaque cap portion connected to the annular portion through which light may not pass. When the inspection device is introduced into the chamber of a firearm into which ammunition is normally loaded, the lightbulb begins to burn. Light is directed by the lightbulb substantially through the annular portion of the light diffusion assembly to fall radially on the interior surface of the barrel. Visual inspection of the barrel is thereby facilitated without temporarily blinding the eyes of an observer. Also disclosed is a method using this inspection device for inspecting the barrel for residue or defects.

Abstract: A self contained, self-powered, bright, typically visible, light source in a strong case having a transparent dome is thrown or fired into position by police as a non-injurious agent of coercive intervention. Light is emitted after a predetermined delay, typically ten seconds, from a unidirectional manual actuation, typically by act of pulling an insulating plastic strip from between electrical contacts within the case. Once activated, the light source may not be readily deactivated, and will shine sufficiently brightly so as to be temporarily blinding to the direct view of any human who is close enough to the light source so as to touch it. A spent light source may be discarded but is commonly recycled by being recharged.

Abstract: A method and system for aiming a small caliber weapon at a target wherein a light beam is directed from the weapon towards an area of the target so as to form a light spot on an object in the target area and the light spot is imaged on a two-dimensional detector so as to form an image thereon whose displacement from an origin of the detector bears a predetermined relationship to a corresponding displacement of the object from a center of the target. The image of the light spot is projected on to a visor worn by a marksman having a reference mark thereon for visually determining the center of the target, and the cycle is repeated as required until the projected image of the light spot on the visor is coincident with the reference mark.

Abstract: In revolvers that are loaded by swinging or shifting the revolver's cylinder away from alignment with the barrel, an extension of the cantilevered axle pin (upon which the cylinder rotates when the revolver is fired) can be sufficiently exposed so that a specially crafted mounting device can be connected to the axle pin. Connection is accomplished by simply sliding the mounting device longitudinally over the distal end of the pin (or an extension thereof). A common extension of the cylinder's axle is an ejector rod that is used to eject spent shells from a cylinder. Typical ejector rods have both the strength and the precision that makes them well suited to function as anchors for a mounting device. When a cylinder and its axle pin are rotated back to a closed position with respect to the revolver's frame, the mounting device is captured by rigid parts of the revolver (e.g., the barrel and/or a part of the frame)--so that the device will remain fixed until the cylinder is again opened.
