System and Method for Resonant Acoustic Fire Suppression via Linear Driver or Thermoacoustic Generation
20230277885 · 2023-09-07 ·

A novel fire control and extinguishing method intended for a Fire Suppression System. This system can be mounted statically, deployed from a vehicle, or incorporated into a complete unmanned vehicle (autonomous or remotely operated) using an electrical system or thermoacoustic means to generate acoustic waves to accomplish fire control and/or fire suppression. This approach eliminates the need for a vehicle to carry chemical flame retardants/extinguishers, or other traditional fire combating means, resulting in an impactful environmental footprint reduction and a marked specific efficiency improvement. The acoustic wave is generated through thermoacoustic or mechanical means using a linear actuator of magnet-and-coil, piezoelectric, or magnetostrictive construction and operating near mechanical, electrical, and acoustic resonance to reduce system power and mass.

Portable fan

The present invention is directed to a portable fan for the use in firefighting and other ventilation use-cases. The portable fan provides firefighters the ability to provide positive pressure ventilation in use for fighting fires which does not require power cables or combustible fuel powered motors, and provides increased portability, reduced risk, and reduced deployment time associated with managing and fighting a fire.
