Abstract

Abstract The apparatus is an interactive, scenario based simulator for training a weapons team in close encounter combat. Employed is a large screen projection system, a plurality of trainee positions, and means to remove aggressor images when neutralized by the team, to provide an apparent threat to the trainees from the simulated aggressors, and to track each trainees performance throughout the training scenario.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 290 words
Apparatus to display a scenario to at least one weapons trainee, and to remove an action video segment having within it an aggressor threat from the display in response to accurate and timely use by the trainee of the trainee's simulated weapon against the aggressor threat, comprising: video projector for projecting a prerecorded video image; display screen for displaying the image projected by said projector; trainee's simulated weapon having a source of infrared energy enabled by the trigger of the simulated weapon; means for identifying the location on said screen illuminated by said source of infrared energy; an electronically prerecorded scenario on optical disc of at least one action video segment having a plurality of frames and an aggressor threat image therein that moves, and at least one still video segment of background; playback means hosting said disc for providing the at least one action video segment for projection by said projector; means for generating a window for each action video segment dimensioned sufficient to encompass the live action venue in the video; means for displaying within a selected said still video segment the window of a selected said action video segment by opening a live video window for the selected action video segment within the selected said still video segment; means for identifying the location on said screen of the aggressor threat image; means for correlating the identified location on said screen illuminated by said source of infrared energy to the location on said screen of said aggressor threat image; and means coupled to said correlating means for removing the window of selected said action video segment by closing said live video window when said location illuminated by infrared energy is within said location of said aggressor threat image.
Claim 2
Dependent Claim 290 words
Apparatus to display a scenario to at least one weapons trainee, and to remove an action video segment having within it an aggressor threat from the display in response to accurate and timely use by the trainee of the trainee's simulated weapon against the aggressor threat, comprising: video projector for projecting a prerecorded video image; display screen for displaying the image projected by said projector; trainee's simulated weapon having a source of infrared energy enabled by the trigger of the simulated weapon; means for identifying the location on said screen illuminated by said source of infrared energy; an electronically prerecorded scenario on optical disc of at least one action video segment having a plurality of frames and an aggressor threat image therein that moves, and at least one still video segment of background; playback means hosting said disc for providing the at least one action video segment for projection by said projector; means for generating a window for each action video segment dimensioned sufficient to encompass the live action venue in the video; means for displaying within a selected said still video segment the window of a selected said action video segment by opening a live video window for the selected action video segment within the selected said still video segment; means for identifying the location on said screen of the aggressor threat image; means for correlating the identified location on said screen illuminated by said source of infrared energy to the location on said screen of said aggressor threat image; and means coupled to said correlating means for removing the window of selected said action video segment by closing said live video window when said location illuminated by infrared energy is within said location of said aggressor threat image.
Claim 3
Dependent Claim 41 words
The apparatus of claim 1 wherein said electronically prerecorded scenario comprises a plurality of action video segments having branches of alternative action segments such that variable activity by the aggressor threat may be displayed form a common point within a scenario.
Claim 4
Dependent Claim 26 words
The apparatus of claim 2 further comprising a general purpose computer programmed coupled to said playback means for selecting branch segments of said action video segments.
