Abstract: Stovetop fires are among the more prevalent of resident fire hazards and smoke detectors are among the most prevalent and economical forms of residential fire alarms. Automatic stovetop fire extinguishers can prevent property damage and even personal injury; however, these stovetop fire extinguishers may also limit smoke emissions and the subsequent detection of smoke. While an initial fire may be efficiently subdued by an automatic stovetop fire extinguisher, it is often desirable to alert present and future occupants of a fire hazardous condition. A sound based fire alarm system and method are described herein, which detects a sound burst emitted upon deployment of an automatic stovetop fire extinguisher and triggers a continuous fire alarm to alert occupants of a potentially fire hazardous condition. Alarm signals can be audible, visual, or both. The system may be a stand alone system and use battery power for affordability and ease of installation.

The internal fire extinguishing assembly is connected to the inner ball cage so that the valve assembly will be disposed on top when the fire extinguishing ball is at rest. The ball can be tossed or rolled towards fires in difficult to reach areas. Exposure to heat opens the valve in the valve assembly to thereby disperse the contents of the body and extinguish the flames.

Abstract: Aqueous droplets encapsulated in a flame retardant polymer are useful in suppressing combustion. Upon exposure to a flame, the encapsulated aqueous droplets rupture and vaporize, removing heat and displacing oxygen to retard the combustion process. The polymer encapsulant, through decomposition, may further add free radicals to the combustion atmosphere, thereby further retarding the combustion process. The encapsulated aqueous droplets may be used as a replacement to halon, water mist and dry powder flame suppression systems.
