Embodiments disclosed herein relate to simulator systems and, in particular, to a weapon training system.
Intensive and frequent training of armed forces personnel is indispensable for the acquisition of the skills necessary to successfully complete military and law enforcement missions. However, the training of armed forces personnel to correctly and reliably handle weaponry is inherently dangerous in case live ammunition is being used for such training. Therefore, weapon simulator systems have been developed that do not require live ammunition during training of armed forces personnel in the handling of handheld or man-portable weapons.
Such a weapon simulator system may for example include a laser transmitter that is coupled to or mounted on a portable weapon such as, for example, a M16 rifle or a machine gun. The laser transmitter may emit laser light responsive to the pulling of the trigger of the weapon. The propagation of the emitted laser light is descriptive of the trajectory of live ammunition that would be fired by the weapon responsive to the pulling of the trigger.
Each soldier/trainee may be fitted with laser receivers for detecting a hit from another trainee to determine the location of a hit and optionally the time of the event and the identity of the shooter (if encoded by the emitted laser light). The laser receivers are generally incorporated into training vests and/or helmets that must be worn by trainees. These training vests add an additional clothing layer that is not part of the normal troop combat gear, thus disrupting the realism of the training. Further, training vests add an additional cost to the training system, require power and charging and must be managed and accounted for in training sessions.
Such a weapon simulator system may further include a trigger detector that needs to be mounted onto the trigger of the weapon for detecting a press of the trigger.
Most weapons include a fire-selector allowing changes to the fire-mode of the weapon, such as SAFE, SEMI, BURST, AUTO, and so forth. Such a weapon simulator system may further include a fire selector detector that needs to be mounted onto the fire selector of the weapon for detecting of a fire selector state.
This disclosure describes systems and methods for weapons training. A weapon training assembly (WTA) as disclosed herein includes a magazine, a small arms transmitter (SAT), and a weapon adaptor. The components of the WTA are mounted within and on a weapon enabling use of the real weapon for simulated weapons training. The SAT is mounted on the weapon barrel and the combined magazine and weapon adaptor are inserted into the magazine well of the weapon.
Advantageously, both of the SAT and magazine include optical detectors for detecting virtual hits from fellow trainees. Thus, the disclosed WTA provides for installation of optical detectors onto a weapon (as part of the same system used for virtual firing) and obviates the need for a separate detection vest and/or helmet. Further, the WTA includes a bolt detection mechanism for identifying charging of the bolt of the weapon in order to include weapon charging in the simulation. Still further, the WTA includes a trigger detector to detect trigger usage without the need for a specific trigger attachment on the trigger.

Embodiments disclosed herein relate to a weapons training assembly (WTA).
Magazine 110 includes a microcontroller (MCU) 116, which is a computing device for managing functionality for WTA 100, including but not limited to: processing, storage, wired and wireless communication, laser actuation and detection, bolt and trigger detection, and sound and light actuation. SAT 112 also includes an MCU 118, which is a computing device in communication with MCU 116 for managing SAT functionality including but not limited to: generating laser codes, generating flashes, decoding incoming lasers and transmitting the incoming laser decoded info to MCU 116.
A simplified form of weapon 120 is shown in
SAT 112 further includes a laser transmitter 214. In some embodiments, laser transmitter 214 is a MILES compatible laser transmitter. In some embodiments, multiple laser transmitters 214 are provided.
SAT 112 further includes a shot-flash light 212 that is activated when a shot is fired by WTA 100. In some embodiments, shot-flash light 212 may include for example an LED, a laser, or an infrared (IR) light.
Magazine 110 includes a magazine body 310 generally shaped to resemble a real magazine and sized and adapted for insertion into magazine well 130. For example, in some embodiments, a magazine catch 320 is provided on magazine top 322 to mechanically couple to a matching feature (not shown) on an internal wall of magazine well 130. It should be appreciated that magazine 110 and weapon adaptor 114 are adapted in size, shape and position of sensors for the particular weapon 120 that they will be used within. Although
Magazine 110 includes one or more laser detectors 312. In some embodiments, four laser detectors 312 are provided, on each of four sides of magazine 110. Laser detectors 312-1, 312-2, and 312-3 are shown in
In some embodiments, magazine 110 includes some or all of the following internal components (not shown): a GPS receiver, a mobile data communication device, a short-range communication device, and an audio amplifier. Magazine 110 includes a battery that provides power to magazine 110, SAT 112 and weapon adaptor 114. In some embodiments, SAT 112 includes a battery and does not receive power from magazine 110. Magazine 110 also includes a speaker 314 and a virtual-ammunition count indicator 318. Magazine body 310 may be made of a material similar to or identical with that of a real magazine, e.g. a metal or reinforced plastic. In some embodiments, speaker 314 is capable of outputting up to 135 dB firing sounds.
Weapon adaptor 114 is installed inside weapon 120 at the top of magazine well 130. Once installed, it is not possible for cartridges of a regular cartridge-carrying magazine to bypass weapon adaptor 114 for chambering as weapon adaptor 114 blocks the top of magazine well 130. When magazine 110 is inserted into magazine well 130, weapon adaptor 114 attaches to the magazine top part 322 of magazine 110 via a weapon adaptor connector 328. In some embodiments, a mechanical sliding spring connector (not shown) on weapon adaptor 114 holds magazine top part 322.
In some embodiments, weapon adaptor 114 further includes a virtual round loaded indicator 330. In some embodiments, following virtual charging of weapon 120 (pulling back and releasing bolt 122 with weapon adaptor inside weapon 120), virtual round loaded indicator 330 is lit to indicate that a virtual round is loaded for firing. Weapon adaptor further includes a trigger detector 332. The position and type of trigger detector 332 will depend on the weapon type and operation of the trigger 124. Trigger detector 332 includes one or more of a trigger contact sensor, hall sensor, inductive sensor or optical sensor. In some embodiments, trigger detector 332 detects trigger 124 movement by analog measurement of the trigger stroke.
Weapon adaptor 114 further includes a fire selector detector 334. In some embodiments, one or more magnets 336 are provided for attachment of the detectors 332 and 334 to the weapon 120. Detectors 332 and 334 are in data communication with weapon adaptor 114 via wired or wireless communications. It should be appreciated that the shape of a trigger detector 332 and fire selector detector 334 as well as the position of magnets 336 will be dependent on the physical structure of the weapon 120 to be used. The position and type of fire selector detector 334 will depend on the weapon type and operation of the fire selector 132.
In some embodiments, as shown in
Weapon adaptor 114 includes a wired communication and power connector 326 for connecting weapon adaptor 114 (and magazine 110) with SAT 112 using cable 115 (
In use, magazine 110 is inserted and removed from a weapon just like a real magazine. Count indicator 318 indicates the number of virtual shots fired and magazine 110 stops the virtual firing after a predetermined number of virtual shots (e.g. 29 virtual shots in a regular training magazine), when the magazine is “empty”. The magazine must then be removed and reinserted and a bolt 122 charge must be detected by weapon adaptor 114 to reset the virtual ammunition count.
When trigger 124 is pressed, the action is detected by trigger detector 332 and conveyed to magazine 110. The virtual ammunition count is checked to see if there are virtual cartridges in the magazine. If Yes, a shot accompanied by sound and light effects is fired. If No (the counter indicates zero virtual cartridges), there is no shot. The trainee then needs to change the magazine, i.e. remove it from, and reinsert it into the weapon and charge the bolt.
Upon detection and registration of a hit by one of detectors 210 and/or 312, magazine MCU 116 may perform post-hit actions. Post hit actions include but are not limited to emitting a sound such as through speaker 314, preventing further shooting from weapon 120, and/or flashing a light source worn by the trainee.
In step 402 of process 400, weapon adaptor 114 is installed into the top of magazine well 130. SAT 112 is clamped onto barrel 128 using barrel mount 222. SAT 112 is connected to weapon adaptor 114 using connector 326. In step 404, magazine 110 is inserted into magazine well 130 to engage with weapon 120, such as with magazine catch 320. Magazine 110 engages and connects to weapon adaptor connector 328. Magazine 110, SAT 112 and weapon adaptor 114 are now activated and in data communication.
Further, magazine 110 is updated to have a full magazine's worth of virtual rounds for use in the weapon training. The number or level of fullness of magazine 110 with virtual rounds is shown by ammunition count indicator 318.
In step 406, weapon 120 is charged by charging bolt 122. Weapon adaptor 114 detects the weapon charge and “chambers” a virtual round as indicated by virtual round indicator 330.
In some embodiments, fire selector 132 is switched form a “safety” position to a firing position and fire selector detector 334 detects that the weapon may now be fired.
Weapon 120 is now ready to be virtually fired as part of training.
In step 408, a trainee presses trigger 124 to fire a virtual round. The trigger press is detected by trigger detector 332 of weapon adaptor 114 and communicated to magazine MCU 116. In response to firing a virtual round, MCU 116 performs one or more of: decreasing the number of available rounds in magazine 110; causing a laser transmission from laser transmitter 214; causing a sound from speaker 314; and/or causing a light flash from shot flash light 212. Virtual rounds are targeted according to the aiming direction of laser transmitter 214. WTA 100 may be used for firing at other trainees having detectors 210 and/or 312 attached to their weapons, and/or trainees with detectors on their clothing (helmets, vests), and/or static or mobile targets.
After step 408, before another virtual round can be fired, MCU 116 determines whether any virtual rounds remain. As long as virtual rounds remain, they may be fired as step 408 is repeated. When no virtual rounds remain, the trainee needs to perform those actions that simulate reloading and charging the weapon. Thus, in step 412, magazine 110 must be removed and then steps 404 (insert magazine) and 406 (charge weapon) are performed again. After step 406, weapon 120 is again ready for virtual firing.
In step 414, it is detected by any of laser detectors 210 and/or 312 that a laser virtual shot of another weapon has “hit” weapon 120 (herein referred to as a “virtual hit”). Detection of a hit is here shown as occurring after step 408, but in practice a hit may be detected by detectors 312 even before insertion of magazine 110 in step 404. Detection of a hit by detectors 210 can only occur after step 404 once magazine 110 is supplying power to SAT 112. In some embodiments, a head detector on a helmet (not shown) is also able to detect hits. The hit detection is communicated to MCU 116. In step 416, the hit is indicated by one or more of: emitting a sound such as through speaker 314, preventing further shooting from weapon 120, and/or flashing a light source worn by the trainee such as on a helmet.
