A controller (42) is in communication with the electrical impulse element (44). The controller (42) enables receipt of a signal (54) for activating electrical impulse element (44) to deliver a non-disabling electrical pulse (46) to the user (26). The electrical pulse (46) simulates an impact of the projectile on the user (26). ## Claims ### Claim 1 A method of threat training using a projectile simulation system comprising: mounting an electrical impulse element of said projectile simulation system in physical contact with a user, said electrical impulse element including a housing containing an impulse generator for generating a non-disabling electrical pulse and a pair of electrodes in electrical communication with said impulse generator; presenting a scenario as a video sequence on a screen of said projectile simulation system; determining a reaction by said user in response to a threat presented in said scenario; and selectively delivering said non-disabling electrical pulse to said user via said pair of electrodes in response to said reaction, said non-disabling electrical pulse simulating an impact of a projectile. ### Claim 2 (depends on 1) A method as claimed in claim 1 wherein said electrical impulse element further comprises a clip coupled to an outer surface of said housing for attachment to said user, said pair of electrodes are imbedded in a user contact side of said clip, and said mounting operation comprises attaching said electrode impulse element at a pre-determined location on said user to simulate a shot fired from a weapon impacting said pre-determined location. ### Claim 3 (depends on 2) A method as claimed in claim 2 wherein said projectile simulation system includes a plurality of electrical impulse elements, each of said electrical impulse elements including said housing containing said impulse generator, said clip for attachment, and said pair of electrodes imbedded in said user contact side of said clip, and: said attaching operation comprises attaching said electrode impulse elements at various locations on said user; and said selectively delivering operation comprises determining at least one of said various locations at which to deliver said non-disabling electrical pulse, and enabling delivery of said non-disabling electrical pulse to said user at said at least one of said various locations. ### Claim 4 (depends on 3) A method as claimed in claim 3 wherein said determining and enabling operations are performed by an operator positioned away from said user. ### Claim 5 (depends on 2) A method as claimed in claim 2 wherein said projectile simulation system includes a plurality of electrical impulse elements, each of said electrical impulse elements including said housing containing said impulse generator, said clip, and said pair of electrodes imbedded in said user contact side of said clip, and: said attaching operation comprises attaching said electrode impulse elements at various locations on each of said user and a second user; and said selectively delivering operation comprises determining at least one of said various locations on either of said user and said second user at which to deliver said non-disabling electrical pulse, and enabling delivery of said non-disabling electrical pulse to said either of said user and said second user at said at least one of said various locations. ### Claim 6 (depends on 5) A method as claimed in claim 5 further comprising: enabling delivery of said non-disabling electrical pulse to a first one of said electrical impulse elements attached to said user; enabling delivery of said non-disabling electrical pulse to a second one of said electrical impulse elements attached to said second user; and concurrently delivering said non-disabling electrical pulse to each of said user and said second user. ### Claim 7 (depends on 1) A method as claimed in claim 1 further comprising adjusting a delivery duration of said non-disabling electrical pulse to one of a first delivery duration and a second delivery duration, said first delivery duration resulting in a sensation of pain that is greater than said sensation of pain resulting from said second delivery duration, said first delivery duration being longer than said second delivery duration, said first delivery duration simulating a lethal impact of said projectile, and said second delivery duration simulating a non-lethal impact of said projectile. ### Claim 8 (depends on 1) A method as claimed in claim 1 wherein: said presenting operation presents said threat as being an offender poised with a weapon; said determining operation determines that said reaction by said user is a failure to take cover during a pre-determined period of time; and said selectively delivering operation comprises activating said electrical impulse element to deliver said non-disabling electrical pulse to said user to simulate a shot fired from said weapon of said offender. ### Claim 9 (depends on 1) A method as claimed in claim 1 wherein: said presenting operation presents said threat as being an offender poised with a weapon; said determining operation determines that said reaction by said user is to take cover during a pre-determined period of time; and said selectively delivering operation comprises refraining from activating said electrical impulse element to simulate no shot being fired from said weapon of said offender. ### Claim 10 (depends on 1) A method as claimed in claim 1 wherein: said presenting operation presents said threat as being an offender poised with a weapon; and said selectively delivering operation comprises coordinating delivery of said non-disabling electrical pulse with an instance of said offender discharging said weapon. ### Claim 11 (depends on 1) A method as claimed in claim 1 wherein said electrical impulse element is utilized in combination with a laser-based training system, said laser-based training system including a torso harness worn by said user, said torso harness containing infrared detectors, and said laser-based training system further including a weapon that outputs infrared energy, said laser-based training system is configured to produce a device activation signal upon detection of said infrared energy from said weapon by one of said infrared detectors, and said method further comprises: receiving, at said electrical impulse element, said device activation signal from said laser-based training system via a communication link; and generating, at said impulse generator, said non-disabling electrical pulse in response to said received device activation signal for delivery to said user via said pair of electrodes.
