Patent Application No. 61/567,159 filed on December 6, 201 1, by Robert Battis, et al. titled "Dazer-Laser(T ) Stealth, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

P>002) This invention generally relates to a multi-function weapon-mountable non-lethal optical security device, and more particularly to a eapon-mountabie optical distracto/iaser device for optically illuminating, distracting or dazing a person.

BACKGROUND OF THE INVENTION

[0003] Low power white LED flash lights, fixed focus green lasers, and red small col!irnated beam target designation "pencil beam" ksers have been used individually mounted to weapons. In most implementations, the optical device is mounted in the 3, 6 or 9 O'clock po it ns on the weapon.

[0004] Optical dis ractors which operate by "dazing" a target are also known. Such a device is described in. detail in several references, such as: provisional U.S. patent application No. 61 /273,371 filed on August 27, 2009, by Robert Battis, et al. titled "Dazer Laser Mean Beam Improvement" (hereinafter, "Mean Beam Application"), PCT Patent Application No. PCX/US 11/3812! , filed on November 26, 2012 by Battis, et al, titled "Diode Pumped Solid State Green Laser" (hereinafter, "Green. Laser Application"), which are included herein fay reference. This laser, suitable for this application provides the features of a small, efficient, compact and all solid state diode pumped, dual frequency conversion green .laser.

fO OSj "Dazing" refers to the temporary, safe and reversible physiological effect that a laser beam of radiation has on a subject -person's eyes and brain after the person has received a short dose of safe laser radiation. Dazing usually results in momentary flash blindness, lasting a few seconds or as long as the beam is focused on someone's eyes, followed by a feeling of disorientation, and may also result in a mild headache and motion sickness, which may last- several hours. These dazing effects are completely reversible, even after repeated dazings. There are several useful articles describing the physiological background for the effects of a dazing laser on a subject person, One such online article is entitled "Temporal ^'Resolution" and is available at http;//webviston.med.utah,edu lempo.raI.htmL Additional references include: "Flicker an Intermittent Stimulation", Vision and Visual. ^'Perception, Graham, C. H., (ed), New York: John Wiley and Sons, Inc., 1965, and "Research into the Dynamic Nature of the Human Fovea: Cortex Systems with Intermittent and Modulated Light, Phase Shift in Brightness and Delay in Color Perception," De Lange, J Opt Soe Am 48: 784-/89 ( 1958). Dazing is thus a potentially useiki non-lethal form of weapon for use in close quarters, for warning or ocular interruption such as but not limited to security and crowd control,

|O006] Examples of dazing laser devices are also taught In PCT Patent Application Nos.

PCT/LJS 10/36893 and PCT/US 1.0/36932, both to Battis, et a.L also incorporated herein by reference. Green variable focus optical distractors and red targeting lasers are .also in use.

[0007} White LED flashlights have also been mounted on weapons, and are useful, in providing illumination of a potential near target. One disadvantage of using a conventional white LED weapon-mounted flashlight is that the white light will be visible, which will give the position of the user away without triggering optical distraction of the threat target.

fO OS) It is thus desirable to provide for a. small, weapon-mouo ahle device which incorporates a green variable focus optical distraeior, Hi power white LED flashlight, and red targeting laser in one small integrated package that can be. mounted in all weapon positions. This multi-function device not only provides new and improved optical distraction using variable range and focus and MEAN Beam, technology (see Mean. Beam Application) hut allows the solder to remove duplicated devices from his weapon.

[00231 in the following description, for purposes of explanation, specific numbers, materials and eoTi figurations are set forth in order to provide a thorough understanding of the invention. It will he apparent, however, to one having ordinary skill in the art, that the invention may he practiced without these specific details. In some instances, well-known features may be omitted or simplified so as not to obscure the present, invention. Furthermore, reference in the specification to "one embodiment' or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

j¾024j An. embodiment of the present invention, advantageously provides for a small, weapon -mo untabie device which incorporates a green variable focus optical distractor. Hi power white LED flashlight and red targeting laser in one small integrated package that can be mounted in all weapon positions.

{0025J One embodiment of the invention, the DAZER LASER STEALTH (TM) by Laser Energetics, Inc., presents is a non-lethal mu!ti-range optical distractor which combines the DAZER LASER (TM) technologies as provided in the Mean Beam Application and the Green Laser Application, which are included herein by reference in their entireties, in a militarized package with special unique features and multiple wavebands to enhance tactical effectiveness. The DAZER. LASER STEALTH (TM) is also referred to herein as the "Stealth", "the weapon- mountab!e laser distractor" or simply "laser distractor".

[0026] An embodiment of the invention includes a hand held or weapon mountabie small light weight package, as depicted in Figure 1. This laser distractor projects a laser beam of radiation (120) which optically distracts and temporarily impairs the vision of the threat. One embodiment of the package concept is illustrated in Figure 1. The laser distractor uses Laser Energetics, Ine.'s MEAN Beam laser technology, which is explained in greater detail in the Mean Beam Application, which drives the current to the laser. In. addition to a Green Laser optical distractor (120) mode the laser distractor includes other radiation modes, including, but not limited to an IR Laser illuminator/Target Designator (130) .mode and a White LED Searchlight (140) mode for area illumination. The multiple apertures are protected by a weather sealed spring loaded integral optic cover (1 .10).

[0027| The laser distraetor also includes -an optical zoom feature (220), or a variable range and focus feature, which is also described in farther detail in the Mean Beam Application, which allows the user to vary the radiation intensity or finance at any desired range ir ni 5 to 1000 meters by adjusting the radiation beam size. The beam size is adjusted by the zoom control buttons (220), and the display (260) displays the selected range.

[0028] One embodiment of the present invention provides the ability to operate the laser distracior with, a remote control (300) button separatel tapped to the weapon. This feature allows the laser distraetor to. e optically zoomed to any desired range, and to then allow radiation to be emitted from one of the apertures (120, 130, 140) as preselected by the mode control (240) switch. The display [260] shows the range setting for the laser mode selected. The remote control button may be either tethered, to the laser distraetor by an electrical umbilical cord or eomrntmisaie with it using a wireless RF (radio frequency) link. In. order t increase battery life, the remote control mode is preferably activated by the remote control (230) switch,

(002.9] The laser distraetor is normally activated by the fire button (2501 which, immediately allows radiation to be emitted from one of the optic apertures based on the control switch mode (240) selected. If the Remote control (230) is activated, the Fire button (250) is also active. Radiation at normal intensity will be emitted from the optic apertures after the integral optic cover (110) is manually opened. This cover (.1 .10) is preferably opened by spring action by relieving the slide latch with finger or thumb.

{00301 The cove (1 10) is designed to be less than 100% opaque to allow a trace amount of radiation to be visible to the user. This allows the user to verify proper operation of the selected- radiation mode without exposing his position in a. tactical situation. In addition to the marginal opacity of the cover, there are fiduciary marks which allow the user to j udge whether the laser beams are set for short, mid o long range.

[0031] In addition to the tactical radiation modes herein described,, the laser distraetor provides a training mode wherein the green laser optical distraetor (120) aperture is reduced in power to the point where it will not daze an individual . but will, produce sufficient radiation to allow training in optical zoom control and development of short range tactics,

I0032J An embodiment of the mveniion. also includes an articulated mounting adapter ( 150} which allows the laser distraetor to be connec ed to any weapon's standard Picatinny Rail and incorporates pitch and. yaw adjustment for the purpose of bore-sighting the laser distraetor to a weapon's target aiming device. An additional feature of this mount and the desig of the laser distraetor package is that it may be mounted below the weapon, and to the right and left sides (3. 6 and 9 o'clock, positions) with all features- economically accessible.

[00331 Key internal elements of the various embodiments of the laser distraetor are illustrated in Figure 2. These elements, are described as .follows:

1 ) Visible laser module (400]; Optical Distraction Green Laser operating at 532 mn_s controlled by a LEFs MEAN Beam laser technology from the microprocessor in the electronics module.

2) 01 LASER module [405]: IR Laser operating at 860 or 880 nm which is used as a source for area illumination (flooding) o Target Designation (pointing).,

3) Visible LED module [410]: 150 to 250~iomen white LED source for short range visible area illumination (flooding)..

4) Visible LASER, optic module [420]; Focusable optic module used to project and focus the laser beam between 5-1000 meters.

5) !R LASER Optic module [425 J: Focusahie optic module used to project and focus the IR laser beam from a wide beam for area flooding to a pencil beam for targeting,

6) Visible LED optic module [430]: Fixed focus optic to project the LED light with moderate divergence for short range illumination.

7) Controls module [440]: Electro-mechanical switch to control operating modes through the microprocessor. 8) Indicator module [450]: A series of LED indicators controlled by the microprocessor, for example: power on, low battery, laser firing and remote enabled.

9) Remote module [460]: Short range RF receiver and decoder to interpret the 3 signals from the remote button.

.10) Control electronics module [470]: Microprocessor based electronics that controls all aspects of the S tealth

1 1 } Display module (480): Display to- show laser beam range selling or focused range for selected laser mode.

12) Battery modul [49 1; Formed cavity to contain multiple commercial, batteries with proper electrical connection to the electronics module,

[ 934| ^"file laser dlstractor package features a hermetically sealed envelope containing all the key internal- lements listed above, except the battery module. This envelop is pressurized to <1. atmosphere with dry nitrogen. The battery module is sealed by a threaded end cover [ 160] to the prevailing atmospheric pressure,

[9.935] One embodiment of the invention referred to in Figure 1 as "Stealth Concept A" is characterized by the 12 internal features listed above and. the external articulated mounting adapter ( 150) which allows the Stealth to be connected to any weapon^'s standard Picatinny Rail. Another important embodiment, referred to in. Figure 3 as. "Stealth Concept B", has the articulated mounting adapter (.150) replaced with a articulated side mounting adapter (155) that is secured to the weapon's Pieatinny Rail. in. both left and right configurations, -and without pitch and yaw adjustment. The pitch adjustment (156) and yaw adjustment (157) in the embodiment of Figure 3 are placed on the laser distraeior body and control internal: elements associated with the optical beam projections. "Stealth Concept B" also adds additional status indicators, shifts the location of certain elements and adds body features, all not critical to the underlying concept, but result .in a unique Stealth Concept B dev ce enclosure (105). |ΘΘ36] Moving the pitch and yaw adjustments from the articulated mounting adapter (150} to the Stealth B device enclosure (105) provides an important internal change to the "Stealth Concept A" interna! elements as illustrated m Figure 2. This change is illustrated in Figure 4 with the addition of the optical beach (401 ). which controls the pointing direction or bore sighting of both the visible laser (400} and IR laser (405) with respect to the Pieatinny Rail attached to the articulated side mounting adapter (155). All other internal elements of the ''Stealth Concept £T are essentially the same as those of the "Stealth Concept A" embodiments.

|0037J Yet another embodiment of the invention is provided as "Stealth Concept C and illustrated in Figure 5. "Stealth Concept C" Is a modification of "Stealth Concept B" in which the internal components and enclosure controls are shifted to allow a. top surface cavity (107) to be formed. This Cavity allows the "Stealth Concept C^* laser distractor to be mounted to a weapon's top Pieatinny rail or 12 O'clock position^' without interfering with the field of view of the weapon's telescope .field of view (FOV) or mounting. A "Stealth Concept C" laser distractor may alternatively be mounted to any of the other three weapon tail positions (3, 6 and 9 o'clock positions),

(0038] The "Stealth Concept C" laser distractor also features a built-in rail adapter ( 158) located on th bottom of the enclosure (.106) and rail cam lever (159), thus eliminating the external articulated side mounting adapter (155) and articulated mounting adapter (150). The rail adapter (158) is a "Stealth Concept C enclosure (106) molded negative form of the Pieatinny Hall with one side notched to allow the rail earn lever (159) to engage the rail and lock the laser distractor to this Pieatinny Rail. 003 1 ϊη addition, the "Stealth. Concep C" apertures are relocated and the aperture cover is called the rotating optic cover ( 1.12), which covers^' only the IR and green laser apertures and. rotates about the white LED aperture. The cover .retainer (.1 13) is an enclosure molded feature to hold the cover when open. Otherwise, the "Stealth Concept C" laser distractor retains all other features of the "Stealth Concept A." and "Stealth Concept B", not specifically delineated here.
