Description
BACKGROUND OF THE INVENTION

Many people own small firearms, such as revolvers, pistols, and rifles for sport and for protection. The United States Constitution and state laws permit people to protect themselves. A person may use force, even deadly force, against another person when he/she reasonably believes that such force is immediately necessary for the purpose of protecting him/herself against the use of unlawful force by such other person. For a firearm to be used in this manner it needs to be quickly and accurately discharged or else it may provoke return fire and result in personal injury or even death.

A very simplified process describing the discharge of a firearm, such as a handgun, is to load with ammunition, aim the gun at a target, and fire the gun by actuating a trigger. The most common means to aim a gun is the visual alignment of a target with front and rear mechanical sights typically located along the top barrel of the gun. While aiming, the top of the front sight should be level with the top of the rear sight and the front sight should be centered left/right within the horizontal opening of the rear sight. Accurate firing using mechanical sighting requires that the target location, front sight, and rear sight be carefully aligned on the optical axis of the shooters eye to achieve success. This is not a process that lends itself to rapid response in an emergency situation. Many times a gun will need to be discharged rapidly and is aimed in an intuitive process where the gun is pointed at the target without mechanical sighting and then discharged. The accuracy when firing in this manner is marginally effective at short distances and relatively ineffective at longer distances.

The aiming accuracy problem has been addressed with the advent of the development of a laser sight. U.S. Pat. No. 5,179,235, entitled “Pistol Sighting Device”, issued Sep. 10, 1991 to Toole, and U.S. Pat. No. 4,934,086, entitled “Recoil Spring Guide Mounting for Laser Sight”, issued Jun. 19, 1990 to Houde-Walter, illustrate the utility of lasers for aiming firearms, such as guns and rifles. After a laser is calibrated to a firearm, a visible red laser dot shines on the target at the location that a bullet will strike when fired upon. The firearm can rapidly acquire a target and be fired from positions not requiring mechanical sighting. The laser system overcomes the aforementioned limitations for rapid firing and accuracy and provides a viable means to protect oneself with a firearm. It will be appreciated that laser sights are currently available as accessories for firearms and are available as factory integrated features on stock firearms. When purchased as an accessory there are a host of universal attachment methods known in the art to fasten the laser assembly to a firearm. Many firearms even come with accessory mounts built in. Sometimes the lasers are mounted below the firearm's barrel, sometimes above the firearms barrel, and sometimes along side the firearm's barrel. Additionally the calibration of the laser to the firearm needs to take into account basic targeting variables such as range (elevation) and windage. These adjustments are generally made with mechanical alignment set screws or thumb screws to position the laser to shine at the point of bullet impact and are also well known in the art. To assist in the calibration, range finders that calculate the distance from the firearm to a target are readily available. Some rangefinders are simple optical sights, some use sound waves, and some use modulated laser light. Laser sights require power that generally is provided by batteries, such as Alkaline or lithium batteries. Some laser sight models take into account power conservation and have a momentary push button activated by the thumb on the firearm's grip. Other laser sight models conserve power by pulsing the laser instead of simply leaving the laser on steady state. Most laser sights, however, just have on/off slide switches that steadily drain the batteries.

One of the statistics that is important concerning use of firearms for protection is that over 80% of shootings happen in low light situations. Many accessories for firearms contain either a visible flashlight or an IR flashlight for night vision. The ability to aim in low light situations with a visible flashlight introduces another dangerous issue. While the visible light allows the shooter to aim effectively, it also creates a clear target for an intruder to aim back. To circumvent the risk of illuminating oneself as a target for your opponent, U.S. Pat. No. 5,584,137, entitled “Modular Laser Apparatus”, Dec. 17, 1996 issued to Teetzel, includes the use of IR lighting and IR laser sights. When a shooter does not wish to endanger themself as a target, they switch to IR illumination and IR laser sighting. While no visible signature illuminates the shooter to an opponent, the shooter must now wear night vision seeing technology, preferably in goggle form, to view the intruder. Typical night vision equipment consists of a low light-level CCD camera with an image display. Night vision equipment has in the past been bulky and is certainly not designed for rapid response. Upon engagement with an intruder, a person seeking to protect themselves would have to power up the night vision equipment, put the night vision goggles on, locate their weapon, and power on the IR laser, to be in a readiness state. Not only is the time required for this sequence potentially hazardous, the additional motions required can also disclose your location and intent. What is ideally needed is a rapidly actuated firearm for protection that is equipped with a compact calibrated laser sight that can be used in a stealth mode that utilizes non-visible laser illumination and has built in night vision capability for sighting. It will be appreciated that such a firearm of this nature, while portrayed as a weapon of self-defense has many applications for law enforcement and military use as well. As an offensive weapon, this sighting technology facilitates stealth approach and targeting. It can be used with a host of military firearms, such as the M4 carbine and the M16 rifle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1 there is shown a typical handgun 10 that as illustrated is by way of example a Beretta pistol. The handgun 10 has a barrel 15 that is the tube that a bullet travels down when fired. Along the top of the barrel 15 is a mounting base 16, which fastens accessories such as gun sights and scopes to the firearm. There are several types of mounting bases: a Weaver base, a Ruger base, a Leopold base, various .22 bases or “dovetail” bases are the most common. Attached to the mounting base 16 is mounting adapter 17 which fastens a stealth laser sighting system 19 in accessory form in accordance with the present invention to the handgun 10 and contains mechanical adjustment for elevation and windage.

FIG. 2A illustrates the stealth laser sighting system 19, shown by way of example in accessory form in accordance with the present invention. The stealth laser sighting system 19 houses all the components necessary to project a non-visible or visible laser dot, and to then image and display the non-visible dot on its intended target. Referring to FIGS. 2A and 2B the stealth laser sighting system 19 includes laser module housings 21 and 23 which contain laser modules 22 and 24 respectively. The laser modules are factory calibrated to be aligned with parallel axial alignment to each other with beams projected normal to the front surface of the stealth laser sighting system 19. Each laser module contains a laser diode of a specific wavelength, appropriate optics to collimate and focus laser light, and driver circuitry for driving the laser diode. It should be noted that the electromagnetic spectrum is only visible in the range of 380 to 780 nm. The wavelengths of the electromagnetic spectrum immediately outside the range that the human eye is able to perceive are called ultraviolet (UV) at shorter wavelengths (high frequency) and infrared (IR) at longer wavelengths (low frequency). Laser module 22 contains a laser diode that projects visible light and is tuned to a predetermined wavelength, such as a wavelength of 635 nm. It will be appreciated that the visible light emitting laser diode can be tuned to any wavelength that is in the visible spectrum. Laser module 24 contains a laser diode that projects IR non-visible light and is tuned to a predetermined wavelength, such as a wavelength of 830 nm. It will be appreciated that the non-visible light emitting laser diode can be tuned at any wavelength that is outside of the visible spectrum that can be imaged and displayed to make the non-visible light beam visible. An imaging element 25 is used to capture and transmit real-time video. Imaging element 25 is designed to image light in the non-visible spectrum and shift the light into video in the visible spectrum. The imaging element 25 is designed to be in parallel axial alignment with the laser modules 22 and 24 and image the field of view where laser modules 22 and 24 illuminate a target. Ideally the center of imaging element 25's field of view would be located along the axis of the laser modules 22 and 25. In one embodiment of the imaging element 25, the imaging element is a low light level (lux) CCD imager capable of producing a grayscale composite video image. The imaging element 25 has by way of example a 92-degree field of view with a pinhole lens, and has 420 lines of video resolution. Most importantly the spectral sensitivity of the CCD imager is by way of example from 200 nm-1000 nm that allows both visible and non-visible light to be displayed within the visible grayscale output as a video stream. Another important feature of the CDD imager is that it only requires, by way of example, as little as 0.01 Lux illumination, which produces very high contrast images in extremely low light situations. While this embodiment of the imaging element 25 uses a pinhole lens, it will be appreciated that any imager can be outfitted with any combination of lens assemblies to provide a fixed or variable zoom to provide any field of view desired. The imaging element 25 provides a continuous video stream to the image display 27. The image display 27 is provided by any display technology that provides high-resolution video in a compact display that requires minimal power. In one embodiment of image display 27, the display is a TFT graphic video LCD assembly that contains by way of example 640×480 pixels, displays 4096 colors, is a 1.8 inch (45 mm) diagonal display with a 1.8 inch (45 mm)×1.8 inch (45 mm)×0.25 (6 mm) inch footprint. The image display 27 is located on the top surface of the stealth laser sighting system 19 and is angled downward from front to back to allow clear visual inspection while in a comfortable shooting position with the gun held at arms length in front of one's body at chest height. A battery compartment 26 holds by way of example either lithium or alkaline batteries, or batteries that can be recharged and are selected to allow for a predetermined number of hours of usage, such as several hours of continuous use. Universal mounting feature 28 is a keyed mating recess designed to accept all of the previously described mounting adaptors 17. The recessed design requires proper orientation and facilitates a rigid mount that is required to maintain the calibration between the sight and the gun. A three-way switch 29 has by way of example a center off position, a leftmost position powers up all components providing operation in a stealth mode, and a rightmost position powers up all components providing operation in a visible mode.

FIGS. 3A, 3B, and 3C and FIGS. 4A and 4B illustrate another embodiment of stealth laser sighting system 19. In this embodiment the imaging display 17 pivots using hinge 32. Within hinge 32 is a rotary switch 33 that automatically powers up the stealth laser sighting system 19 in a stealth mode when the imaging display 17 is opened. Stealth mode powers up a non-visible light emitting laser 24, imaging element 25 and imaging display 17. This automatic power actuation allows for rapid deployment of a firearm in an emergency situation. To switch to a visible mode, one needs simply to depress a mode switch 34. A single actuation of mode switch 34 will turn off the non-visible light emitting laser 24 and turn on a visible light-emitting laser 22. Actuation again of mode switch 34 will turn off the imaging element 25 and imaging display 17, which conserves power since the visible source can be seen without the aid of imaging element 25 and the imaging display 17. Depressing mode switch 34 again will begin the cycle again and place the stealth laser sighting system 19 into the stealth mode.

FIGS. 3C and 4B show how compact the profile of the stealth laser sighting system 19 is when the display housing 35 is in the closed position. The intent of the narrow profile when the imaging display 17 is closed is to contain the module as much as possible within the confines of the handgun to enable holstering the firearm.

FIGS. 5A and 5B illustrate multiple mounting locations of the stealth laser sighting system 19 to handgun 10.

FIG. 6 illustrates the preferred use of the stealth laser sight 19 when attached to an automatic or semi-automatic firearm 60, which as illustrated is by way of example an M-16 army rifle.

FIG. 7 illustrates the use of a single laser element on stealth laser sighting system 19. This version does not contain the visible laser module 22 or a laser module housing 21.

Referring to FIGS. 8, 9A, and 9B, FIG. 8 illustrates a stealth laser sighting system 19 that uses a dual output laser module 80. The dual output laser module 80 contains a single set of collimating optics, a dual laser diode and driver circuitry. FIG. 9A illustrates a typical schematic for a single mode visible light emitting laser diode 90. Single mode visible light emitting laser diode 90 typically includes a photodiode 92 that is used to provide feedback to control the output of the laser power and includes a laser diode 94 that is tuned to produce laser light in the visible spectrum. FIG. 9B illustrates a typical schematic for a dual mode laser diode 95. The dual mode laser diode 95 includes a photodiode 92, a laser diode 94 tuned to the visible spectrum, and a laser diode 96 tuned to the non-visible spectrum. This packaging conserves cost and space that is critical for compactness, and eliminates the machining tolerance to make the separate visible and non-visible laser modules parallel as described above regarding FIGS. 2A and 2B.

FIG. 10 illustrates the addition of a photo detector 50 that senses laser light for purposes of calculating the range to a target. A laser range finder, or LIDAR (Light Detection And Ranging), uses the laser beam from laser module 22 in order to determine the distance to an opaque object. The laser range finder works by sending a laser pulse in a narrow beam towards a target and measuring how long it takes for the pulse to bounce off the target and return. The pulse can be coded in order to reduce the chance that the laser range finder can be jammed. It will be appreciated that a LIDAR that uses very short (sharp) laser pulses and has a very fast detector can range on object to within a few centimeters. The distance from the firearm to the target is used to set the laser sight elevation, to calibrate where the bullet will strike a target.

FIG. 11 is a view of a circuit board 51 that is enclosed within stealth laser sighting system 19. Circuit board 51 incorporates a micro controller unit 52 that can perform calculations and processes for the LIDAR. Circuit board 51 also can incorporate an accelerometer IC 53 and associated circuitry that can detect motion of the firearm and automatically power up the stealth laser sighting system 19 in stealth mode for quick firearm response. Circuit board 51 also can incorporate a display driver 54 that is used to process all of the video information, add video overlays, and drive the imaging display 27 as required. A memory 62 can be incorporated to record the video information delivered from the imaging element 25. The memory 62 can be permanently incorporated onto the circuit board 51, or can be removable, such as provided using a Flash RAM or a flash memory card. The content of memory 62 can be reviewed or transferred to other media, and used as visual evidence of the circumstances of the discharge of the firearm.

FIG. 12A illustrates an image as seen on imaging display 27 when the stealth laser sighting system 19 is used in stealth mode. A laser spot 55, which is not visible directly on the target to the human eye, shows up on the imaging display 27 on the intended target where a bullet will strike once the stealth laser sighting system 19 and firearm are mechanically aligned and calibrated to each other as described above.

FIG. 12B illustrates the addition of laser apertures 56 that cause the stealth laser sighting system 10 to project a targeting grid 57 on the target instead of projecting just a laser spot 55 as described above. Laser apertures 56 can have, as shown by example, cross hatches that are indicative of windage and elevation adjustments that can be made prior to shooting by aiming the sight through a particular cross hatch on targeting grid 57 instead of the center of the target crosshair on targeting grid 57.

FIG. 12C illustrates the addition of an electronic video overlay of a crosshair 58. The electronic video overlay of a crosshair 58 highlights the location of laser spot 55, which makes the laser spot 55 easier to see on imaging display 27. Additionally the electronic video overlay of the crosshair 58 can have cross hatches that are indicative of windage and elevation adjustments, as described above, that can be made prior to shooting by aiming the sight through a particular cross hatch instead of the center of the target crosshair. In this case the laser spot 55, imaging element 25, and the handgun 10 need to be mechanically aligned, for the calibrations to aim the firearm effectively.

FIG. 12D illustrates when the laser spot 55 and the handgun 10 are not mechanically aligned. To accurately calibrate the stealth laser sighting system 19 and the handgun 10, an electronic video overlay of a crosshair 59 is manually positioned using a button-sized joystick 68 where the bullet would strike when aimed. A similar sighting process known in the art for mechanical alignment of a sight and a gun would be used to perform this calibration accurately. To accurately fire the firearm, the shooter would align the target with crosshairs 59 instead of the actual laser spot 55.

FIG. 12E illustrates an auto laser range finder that would automatically offset crosshair 65 to account for range relative to the laser spot 55. The shooter would aim at the center of the crosshair to place a bullet accurately in the target from the actual distance the firearm was fired.

FIG. 13A illustrates a long range shot as imaged on imaging display 27. Upon actuation of a digital zoom button 69 or rotational adjustment of a zoom lens 77, the image illustrated in FIG. 13B zooms in to fill the viewing screen to make it easier to sight the target. It will be appreciated that both optical zoom, where a lens attached to the imaging device 17 is rotated, and digital zoom, where a portion of the image is digitally enlarged, serve identical functions.

FIG. 14 takes all of the features described above as a modular accessory for a small firearm and integrates the stealth laser sighting system 19 directly into the housing of firearm 100. All of the stealth features and functionality of the stealth laser sighting system 19 are contained within the firearm body and all rigid alignments are maintained.

It will thus be seen that the description set forth above, and those made apparent from the preceding descriptions, are effectively attained and since certain changes may be made in the above construction without departing from the spirit and scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all generic and specific features of the invention herein described and all statements of scope of the present invention, which as a matter of language, might be said to fall there between.
