Provided is a human rescue apparatus that comprises a pulley for vertical extraction of a human using a pulley mechanical advantages system and a fan that is powered by rotation of the pulley to generate airflow in the direction of the user so as to cool the user during vertical extraction when direct aid from rescue workers is typically unavailable. The apparatus has a core mechanism and a support structure. The core mechanism comprises a pulley wheel and a fan coaxially connected together by an axle. The core mechanism is held securely and rotatably in a support structure such that it can freely rotate but otherwise be held by the supporting structure. In some embodiments the supporting structure includes one or more passageway allowing removal of the core mechanism.

In some examples, a system includes an article of personal protective equipment (PPE) having at least one sensor configured to generate a stream of usage data; and an analytical stream processing component comprising: a communication component that receives the stream of usage data; a memory configured to store at least a portion of the stream of usage data and at least one model for detecting a safety event signature, wherein the at least one model is trained based as least in part on a set of usage data generated by one or more other articles of PPE of a same type as the article of PPE; and one or more computer processors configured to: detect the safety event signature in the stream of usage data based on processing the stream of usage data with the model, and generate an output in response to detecting the safety event signature.

Embodiments in the present description are provided for a Bi-pod rescue strut system for use in stabilizing a vehicle or other object. The Bi-pod rescue strut system includes stabilizing feet and support legs. Each of the stabilizing feet is pivotally connected to an end of each support leg so that the stabilizing feet rotate around the support legs. The Bi-pod rescue strut system further includes a yoke disposed at an end of the support legs. The yoke permits the support legs to extend and retract towards or away from the other support leg. The yoke connecting to a telescoping strut extension. The telescopic strut extension extending and coming into contact with vehicle or other object, stabilizing the vehicle or other object.

An aircraft locating device for locating an aircraft that has crashed into a body of water. The aircraft locating device includes a housing having a base, one or more sidewalls, an upper wall, defining an interior volume, wherein at least one wall can be secured to an aircraft. The housing includes one or more openings removably covered by one or more gates that open when the housing is submerged in liquid. A plurality of buoyant objects are disposed in the interior volume of the housing, wherein the buoyant objects can be released therefrom when the gates are open, thereby leaving a visual trail in a body of water in order to allow emergency responders to identify where an aircraft may be located.

A portable safety device (100) for inflating multiple envelopes includes at least one inlet for surrounding air (1), at least one inflation system, at least one enriched air or gas zone, at least one nonreturn valve (2), at least one connector (3) connected to the at least one inflatable envelope (4). The device also includes at least one separation wall (8), which compartmentalizes at least the end of at the connector (3) opening into at least two substantially hermetically independent inflatable envelopes (4).

A victim retrieval apparatus for use with a vehicle. In some embodiments, the rescue basket comprises one or more wheels. The articulating head of the boom comprises a rotatable pulley for receiving the rescue line and is able to allow the vehicle to be parked in any position necessary while rescuing the victim. A knot-passing pulley enables a safety line (with emergency brake device) to be coupled to the basket thereby ensuring the safety of the victim in the basket at all times. The rescue basket comprises a remote control for controlling the winch speed that is able to be located at the winch itself, or be of a hand-held nature and attached at the rescue basket instead of at the vehicle if visual contact is problematic.
