Abstract

Abstract A marksmanship training system has been developed which depends upon the mal levels of infrared radiation emitted from warm-blooded animals, such as humans. An infrared detector is mounted upon a simulated rifle or unloaded real rifle, or other weapon. This detector is mounted with IR lenses in such a way that a positive indication is given when the rifle is pointed at a suitable infrared emitting animal target. A second detector indicates when the trigger of the weapon is pulled. If a trigger pull is detected at a time when an animal infrared signal is present, the system generates an electronic pulse indicating that a target hit has occurred. This pulse may be used to drive a visible or audible signaling device to inform the user of success.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 73 words
A weapons training device comprising: means for detecting infrared radiation emitted by warm-blooded animals, including humans and heated targets; a simulated rifle; and means for detecting when the trigger of the said simulated rifle is pulled; wherein the said means for detecting infrared radiation is mounted upon the rifle in such a manner as to detect radiation emitted by said animals at such times as the rifle is properly targeted at said animals.
Claim 2
Dependent Claim 73 words
A weapons training device comprising: means for detecting infrared radiation emitted by warm-blooded animals, including humans and heated targets; a simulated rifle; and means for detecting when the trigger of the said simulated rifle is pulled; wherein the said means for detecting infrared radiation is mounted upon the rifle in such a manner as to detect radiation emitted by said animals at such times as the rifle is properly targeted at said animals.
Claim 3
Dependent Claim 18 words
The training device of claim 1 wherein the said means for detecting infrared radiation comprises a pyroelectric detector.
Claim 4
Dependent Claim 15 words
The training device of claim 2 wherein said means further comprise a low pass filter.
Claim 5
Dependent Claim 23 words
The training device of claim 3 wherein said means for detecting when the trigger is pulled comprises a switch and a logic gate.
Claim 6
Dependent Claim 14 words
The training device of claim 4 wherein said logic gate is an AND gate.
Claim 7
Dependent Claim 43 words
The training device of claim 5 wherein the said means for detecting infrared radiation further comprise an inverting buffer, a timer, an output disabling circuit, and a flip-flop wherein the output of said flip-flop is connected to an input of said AND gate.
