Abstract
Abstract To simulate the output of a laser to a Multiple Integrated Laser Engagementystem (MILES), an electronic circuit having a PLL subcircuit and a microprocessor is used to detect an acoustic signal having a predetermined frequency and pulse rate. Upon detection of the correct acoustic signal, a prestored universal kill code is provided to an inductive loop magnetically coupled to the antenna coil of a harness to which the MILES is integrated. The thus received inductive signal is recognized by the MILES which in turn outputs an audio alarm to indicate that a kill has occurred.

Claim 1
Independent Claim
146 words
Apparatus magnetically coupled to a MILES-type tactical engagement simulation system having a magnetic loop, comprising: means for detecting a multi-directional acoustic signal having a predetermined frequency; means for converting said detected multi-directional acoustic signal to a first electrical signal; an induction coil means magnetically coupled to said magnetic loop; phase lock loop means for outputting a second electrical signal in response to said first electrical signal to said induction coil means upon detection of said predetermined frequency in said first electrical signal; wherein said induction coil means magnetically couples said second electrical signal to said system to thereby cause said system to output an audible alarm to indicate that an object carrying said system and said apparatus has been hit and further wherein said second electrical signal comprises a universal kill code and wherein no physical interconnection is therefore required between said system and said apparatus.
