Abstract: A system for projecting an image of a target is provided. In one embodiment, the system comprises a rail having a longitudinal axis; a target carrier coupled to the rail such that the target carrier can translate along the longitudinal axis of the rail; a motor and motion controller coupled to the target carrier wherein the motor is configured to cause the target carrier to translate along the longitudinal axis of the rail; a projector carrier coupled to the rail and held in fixed relational position to the target carrier; and a projector affixed to the projector carrier and oriented to point back towards the target carrier. In some embodiments, one or more cameras may also be added to the target carrier, projector carrier, or both.

Abstract: A method for automatically predicting the cause of suboptimal shooting is provided. In some embodiments, the method comprises: providing a plurality of good example reference data to an evaluation function; providing a plurality of bad example reference data to the evaluation function; obtaining training data of a trainee's shot dispersion data; obtaining training data from at least one sensor mounted on the trainee's gun; using the evaluation function to classify the training data as good or bad; and, displaying the classification on a screen as feedback.

Abstract: Provided herein are methods and systems to provide for parallax correction for multiple eye-points in a single viewpoint within a Homogeneous 3-Dimensional (3D) virtual environment. In preferred embodiments, the systems and methods are used as part of a virtual training environment where multiple participants are participating simultaneously. The methods and systems render multiple objects from multiple eye-points by creating custom projection matrix for each eye-point. Each rendered object is overlaid over the background and other images rendered with the standard eye-point projection matrix. Preferred embodiments use the same view matrix for all renderings.

Abstract: A method of calculating the difference between a device clock and a host clock over a communication network is provided. In a preferred embodiment, the method comprises: a.) sending a sync requests over the communication network; b.) storing in memory a sent host time TH0 when the sync requests was sent; c.) receiving a local time report over a communication network from a local device; d.) storing in memory a device local time X extracted from the local time report; e.) storing in memory a receive host time TH3 when the local time report was received; f.) calculating T such that T=(TH0+TH3)/2; repeating steps a through f a plurality of times; and calculating coefficients Ai and Bi using linear regression after repeating steps a through f at least twice where X=Ai*T+Bi.

Abstract: An improved projectile trap assembly includes a frame that supports a channel and a containment chamber. The containment chamber has an ingress point receiving a fired bullet and an egress point for distributing the bullet. The containment chamber is supported by a pair of bulkhead plates that are connected to the frame. Each bulkhead plate defines an aperture, with a scroll assembly being mounted between bulkhead plates proximate the aperture. The scroll assembly includes a front scroll affixed and a rear scroll detachably connected to the bulkhead plates. A side plate is detachably connected to the bulkhead plate opposite said front and rear scrolls to seal the scroll assembly to receive bullets. The containment chamber additionally includes upper and lower trap plates that are positioned proximate upper and lower channel plates at the ingress point. Finally, a plurality of collection buckets positioned below said front scroll in an adjustable position.

Abstract: A target holder assembly for interchangeably supporting a two-dimensional target and a three-dimensional target includes an enclosure and a target holder frame connected to the enclosure, the target holder frame including a cross arm member connected between two target arms. The cross arm has a base length with clamping members extending from both ends of the base length to engage three dimensional targets. The cross arm also has receiving grooves proximate the junction of the clamping members and the base length positioned to engage the two-dimensional targets. A front protrusion is positioned along the base length to engage either the two-dimensional target or the three-dimensional target. The holder assembly further includes a clamping apparatus connected to the base length to engage either the two-dimensional target or the three-dimensional target.

Abstract: A laser stabilization assembly for weapon simulators is used in conjunction with the weapon simulator to steady a laser module. The laser stabilization assembly includes a first spacer, a second spacer and a lock ring that is secured to the barrel of the weapon simulator via a threaded insert and locking components. The assembly is mounted proximate to the barrel of the weapon simulator in the same general area allocated for a conventional laser apparatus of a conventional weapon simulator.
