US Patent:

20110168305, Jul 14, 2011

Filed:

Mar 7, 2006

Appl. No.:

11/369908

Inventors:

Reed J. Blau - Richmond UT, US
Lisa S. Liu - Layton UT, US
Ronald L. Hansen - Tremonton UT, US
Richard G. Ames - King George VA, US

International Classification:

C06B 45/12

US Classification:

149 14

Abstract:

Non-lethal payloads may be customized for particular uses and desired visual and audible incapacitation based upon the selection of igniter/activators and illuminants used with the non-lethal payloads. Non-lethal payloads employing high flame temperature igniter/activators and illuminants of powder metals, powdered metals combined with oxidizers, and powdered metals combined with heat-activated chromophores may produce improved “flashes” and “bangs” for non-lethal payloads used with diversionary or other devices. Such devices and methods of producing illuminance and noise are also disclosed.
