TAP SENSOR FOR WEAPON SIMULATOR
A weapon simulator assembly for monitoring correction of a malfunction of a simulated weapon having a detachably attached simulated magazine includes a central processor for generating the malfunction scenario. A weapon processor is supported in the simulated weapon in electrical communication with the central processor, with an electrical interface connecting the weapon processor with the simulated magazine detachably attached to said receiver. A sensor, such as a tap sensor or accelerometer, is in electrical communication with the weapon processor via said electrical interface, with the tap sensor or accelerometer registering a strike when a force is applied to the simulated magazine above a predetermined value.
This non-provisional patent application claims priority from provisional patent application 60/747,290, which is relied upon and incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to a weapon simulator assembly, and, more particularly, to a simulated weapon of a weapon simulator assembly that is able to detect the tap or slap of a magazine as part of an action drill corresponding to a weapon misfire.
BACKGROUND OF THE INVENTIONWhen military and/or police personnel train with simulated weapons, one of the training scenarios generated by a central computer or central processing unit is a “misfire” of the simulated weapon. In an actual weapon, a misfire occurs when the trigger is pulled, but no round of ammunition is fired. This can occur due to many different reasons, and most agencies have an immediate action drill (a series of steps, done in order, immediately after the firearm misfire) that is to be performed by personnel in the event of such an occurrence. One of the steps included in most drills related to firearm misfire includes a magazine tap or slap, where the user must slap or hit the bottom of the magazine to ensure that it is seated properly in the weapon.
In an attempt to provide more a more realistic simulated weapon, some weapon simulators include a sensor, located within the simulated weapon itself, for the purpose of detecting whether or not a magazine is present and connected with the simulated weapon. The sensor will change states when the magazine is “struck”, in that, during a simulated misfire, the user will push the magazine toward the firearm, and the central processing unit will measure the length of time that the sensor remains at a state indicating that the magazine has been removed from the simulated weapon. If the length of time, or “pulse width,” falls within a preset range, the weapon recognizes the signal as a “tap,” and provides a corresponding signal to the central processing unit.
Although this solution attempts to provide a more realistic experience, a disadvantage of this approach is that if the magazine is pushed up longer than the tap interval, or if the weapon is rested on the magazine at any time, the weapon will process the corresponding signal as a removal and reinsertion of the magazine with respect to the simulated weapon. Consequently, this will reload the weapon, even if that was not the intent of the user, thereby diminishing the likeness of actual weapon operation, which is contrary to the desired result.
Referring to
In more detail, the weapon simulator assembly 8 includes the simulated weapon 10, which has a receiver 11 with a receiver slot 11s to receive the simulated magazine 12. The weapon simulator assembly 8 additionally includes a tap sensor 14 that is able to detect a “tap” force to the magazine 12 and differentiate the tap force from forces associated with the removal and reinsertion of the magazine 12 in the slot 11s. Several embodiments of the weapon simulator assembly 8 are described herein that are able to accomplish this goal, with each of the embodiments utilizing the tap sensor 14 in determining when the user has “tapped” the magazine 12 to correct the simulated malfunction and when an “empty” simulated magazine 12 has been removed and replaced with a “full” simulated magazine 12.
During the simulation, either the central processing unit 4 or the processor 16 in the simulated weapon 10 will generate a scenario of weapon misfire that must be addressed before the simulated weapon 10 is allowed to continue operation. This misfire scenario may be generated randomly, at a predetermined time, or as selected by a person overseeing use of the weapon simulator assembly 8. In such a scenario, the weapon simulator assembly 8 is not only able to monitor the simulated weapon user's choices during the training session with respect to the simulated weapon 10, but it is also able to monitor the operator's reaction to the misfire of the simulated weapon 10.
The first embodiment of the weapon simulator assembly 8 is illustrated in
There are various ways in which such shock sensors function. For example, the tap sensor 14 could include a housing surrounding a metal ball, with the ball being held in a neutral position by a magnet. Upon impact, the sensor 14 is subjected to a shock, and a force is exerted onto the metal ball in an opposite direction as the force of the magnet. If the impact exceeds a threshold value, the ball is loosened from the magnet. Due to the impact on the tap sensor 14, an electrical contact is effectuated, and a signal is transmitted to the processor 16 accordingly to provide the desired feedback, which is then transmitted to the central processing unit 4.
Referring to
In a second embodiment of the invention illustrated in
A third embodiment of the present invention, illustrated in
The processor 16 will then be able to register the action as one performed as a part of the drill to address the simulated malfunction of the simulated weapon 10 and provide a corresponding signal to the central processing unit 4, and allow the user to proceed in the simulation with the remaining number of rounds of ammunition identified for the magazine 12 attached to the simulated weapon 10. The use of an accelerometer 14 therefore provides freedom in the position of the sensor 14 with respect to the simulated weapon 10 and magazine 12.
Having thus described exemplary embodiments, it should be noted by those skilled in the art that the within disclosures are exemplary only and that various other alternatives, adaptations, and modifications may be made within the scope of this disclosure as described herein and as described in the appended claims.
