Navy researching vomit beam

Via the Danger Room blog of Wired, a company is creating a radio frequency device that disorients anyone it is aimed at, and apparently can cause vomiting.

"Invocon, Inc. proposes to investigate the use of beamed RF [radio frequency] energy to excite and interrupt the normal process of human hearing and equilibrium. The focus will be in two areas. (1) Interruption of the mechanical transduction process by which sound and position (relative to gravity) are converted to messages that are processed by the brain. (2) Interruption of the chemical engine which sustains the proper operation of the nerve cells that respond to the mechanical transduction mechanisms referenced in item (1). Interruption of either or both of these processes has been clinically shown to produce complete disorientation and confusion....

The benefits of such a weapon would be that in areas of extreme risk to Marine Corps personnel, hostiles could be controlled without loss of life. The weapon effect would be helpful in urban combat where rooms could be subjected to the EPIC stimulus and then subdued without further risk to friendlies or hostiles. Similar technology could be applied to law enforcement operations especially in hostage situations where all the people in a room could be incapacitated without damage and subsequently sorted out as to which are the bad guys and which are the good guys."
