SAN DIEGO, CA, May 18 (MARKET WIRE) --
American Technology Corporation (ATC) (NASDAQ: ATCO), a leading provider

FPED VII is conducted by the U.S. Army Product Manager, Force Protection
Systems under the sponsorship of several federal agencies including the
Office of the Under Secretary of Defense For Acquisition, Technology &
Logistics, the Department of Homeland Security, the Joint Staff, and
others. FPED brings together knowledgeable leaders from around the world

physical security/force protection needs. FPED provides leaders and
decision makers from the Department of Defense, Federal departments and

agencies the opportunity to observe, and become familiar with, commercial,
off-the-shelf (COTS) physical security/force protection equipment

ATC's LRAD 300X is a compact, lightweight solution for use on small
vessels, common remote-operated weapon systems, and most military and
armored vehicles. It can be easily transported to provide security
personnel long-range communications and a highly effective hailing and
warning capability where needed. The LRAD 300X produces focused, 100%
intelligible voice transmission over 88dB of background noise beyond 200
meters. It can communicate in excess of 1500 meters depending on local
terrain and environment. LRAD 300X operators have the ability to issue
clear, authoritative verbal commands, followed with powerful deterrent
tones to influence the behavior of targeted threats. (Please see the
