- Plasma Acoustic Shield System
The Plasma Acoustic Shield System, or PASS, is in the process of being developed by
Stellar Photonics . The company received a $2.7 million contract from the U.S. Government to build the PASS.

The laser was first tested in 2008, and will continue to be tested into 2009, with the testing of turret-mounted PASS.Function
The device is able to disorientate an enemy using a series of mid-air explosions, and may also use "high-power speakers for hailing or warning, and a dazzler light source" [cite web |url=http://technology.newscientist.com/article/dn11723-plasma-shield-may-stun-and-disorientate-enemies.html |title=Plasma Shield may stun and disorientate enemies |publisher=New Scientist |accessdate=2008-09-22] Its low power would mean that it would be unable to do significant damage to a specific enemy. While it would not be classified as a weapon, because of its inability to stun or disable a target, its distracting light or explosions are hoped to impede the progress of those in its path. "The [PASS] creates a “mid-air plasma ball” that that “basically ignites the air in front of the person...It creates fireworks right in front of you.” [http://dandelionsalad.wordpress.com/2008/07/11/non-lethal-weapons-where-science-and-technology-service-repression/ "Non-Lethal Weapons: Where Science and Technology Service Repression"]
Description
The PASS uses Dynamic Pulse Detonation (DPD), a technology researched by Stellar Photonics wherein two short but powerful laser pulses first create a ball of plasma, then a supersonic shockwave creates a loud flash and bang. Pass is the first functioning DPD weapon system, and it may lead to the construction of a "man-portable tuneable laser weapon that could be used in both non-lethal and lethal modes".
