  • Patent number: 10132482
    Abstract: A rescue torch apparatus utilizes coherent and incoherent light sources to help firefighters navigate through smoke and fire filled environments. The rescue torch apparatus includes a coherent-light emitter, an incoherent-light emitter, an elongated body, a rotatable-activation mechanism, a portable power unit, and an inductive receiver. The incoherent-light emitter emits continuous light for general illumination or short bursts of light to activate photo-luminescent display panels worn by firefighters. The coherent-light emitter emits beams of coherent light that penetrate through smoke filled environments and outline obstacles. The elongated body houses and protects the coherent-light emitter and the incoherent-light emitter. The rotatable-activation mechanism allows for hands-free operation of the light sources. Power is provided by a portable power unit mated to an inductive receiver for wireless recharging.
