Damage mitigating apparatus comprises totally extending hollow tubes, and projectiles attached to undeployed fabric and formed with a tube-receivable rod. Pressurized gas which is generated upon triggering of a gas generator flows through the tubes to propel the projection and to cause performance of at damage mitigating operation. In one embodiment, a damage mitigating aerial vehicle comprises sensors for detecting flight related characteristics and a communication unit for commanding activation of parachute deploying apparatus and of a lift generator deactivation unit following determination of a flight failure. In one embodiment, an aerial vehicle transmits a critical failure alarm signal to an unmanned aircraft traffic management system (UTM) station following detection of to failure, and the UTM elation transmits a warning signal to neighboring aerial vehicles that are predicted to be in a vicinity of the descent path of the failed aerial vehicle to avoid collision with the failed aerial vehicle.

An emergency system is disclosed that includes an elongated inflatable slide portion that in the inflated condition has an upper end portion, an enlarged lower end portion and a middle portion therebetween, the slide portion optionally further includes a pair of raised side portions to assist with retaining an evacuee on the slide portion. The system is moveable from a ready position inside the building to a deployed position outside the building, wherein, in an embodiment, a release button in the ready position is arranged and configured to face an interior wall of the building, and in the deployed position is arranged and configured to face outward and be readily accessible by a potential evacuee. The slide may optionally include side support members, one or more securement straps, and other features.

Disclosed is a lifesaving system using a drone and a lifesaving method using the lifesaving system. The lifesaving system includes: a lifesaving drone provided with a parachute, the drone approaching a victim by being remotely controlled and installed in the victim, and assisting rescuing the victim from a high-rise building by operating the parachute; and a disaster management center disposing a rescuing vehicle to a disaster occurrence area and remotely controlling the lifesaving drone when a disaster report is received, or a disaster occurrence area is recognized.

In an aspect, a crash bag is provided, which includes an impact structure and an outlet valve. The impact structure has a first bag wall partially defining a first bag air chamber having an inlet for receiving pressurized air, and having a first operating pressure, and a second bag wall partially defining the first bag air chamber and partially defining a second bag air chamber having an inlet for receiving pressurized air and that has a second bag air chamber operating pressure. The outlet valve discharges air from the second bag air chamber upon an impact on the impact structure. The second bag air chamber includes fluidically connected projections that are adjacent one another. The first bag wall is positioned atop the projections and extends across the projections such that the operating pressure in the first bag air chamber is applied to all the projections.

The present invention relates to a parachute deploying apparatus, comprising: a) a manifold with which is releasably coupled a single vessel within which pressurized gas is generated; b) a gas generator which cooperates with said vessel; c) a plurality of hollow tubes which extend obliquely and upwardly from, and are in communication with, said manifold; and d) a plurality of projectiles, each of which formed with a rod that is receivable in a corresponding tube and to each of which is connected a cord that is also connected to a corresponding portion of an undeployed parachute, wherein the pressurized gas which is generated upon triggering of said gas generator is flowable through each of said tubes to propel said plurality of projectiles in different directions and to cause said parachute to become deployed.

A safety airbag device for cushioning the free fall of a person or object from an elevated height. The airbag device includes an inflatable base bag capable of sustaining an air pressure and an inflatable structure coupled to the base bag, where the inflatable structure is in air communication with the base bag. A net is coupled to a top portion of the inflatable structure for decelerating and supporting the individual from free fall. A top cover is coupled to the base bag that substantially encloses the inflatable structure.
