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 expandable baton structure with a hidden smasher at the rear end of a handle includes an outer tube and at least one inner tube in addition to the hidden smasher. The inner tube can be stored in the outer tube to form a short-stick configuration. The front end of the inner tube can also extend completely out of the outer tube to form a long-stick configuration. The hidden smasher is mounted at the rear end of the handle formed by the outer tube. While the hidden smasher is not in use, its smashing cone is stored in a protective cover. To use the hidden smasher, the protective cover is pressed against the surface of a to-be-smashed object and pushed for a predetermined distance in order for the smashing cone to extend out of a through hole in the protective cover and thereby smash the to-be-smashed object.

A method of providing a safety system includes: (a) providing a first rope or lanyard to which a first attached safety hook is attached; (b) retrofitting a first load detection sensor to the first safety hook without altering the structural integrity of the first safety hook by mounting the first load detection sensor on or shrink wrapped on the first safety hook; (c) detecting a load by the first load detection sensor; (d) generating a load status signal by the first load detection sensor in response to the detecting of the load; and (e) via a transmitter arranged to receive the load status signal from the first load detection sensor, receiving the load status signal from the first load detection sensor and transmitting the load status signal therefrom.

The present invention relates to an avalanche protection device that includes an avalanche protection backpack with at least one inflatable buoyant airbag and a breathing system with a breathing housing. The breathing housing connects a one-way inhalation valve to an inhalation tube, and at least one intake port, and at least one ambient air suction zone. It also connects a one-way exhalation valve to an exhalation tube and a CO.sub.2 exhalation region. A mouthpiece is provided on the breathing housing, which is able to be automatically pulled tightly onto the mouth of an avalanche victim by means of a facial airbag, by actuating a trigger handle. The invention additionally relates to a method for using such an avalanche protection device.

A safety device, tie cutter designed to be worn about the neck on a conventional neck tie and concealed from view by the shirt collar that can quickly sever the neck tie by manually pulling on the device. The tie cutter includes a thin flat body and an embedded blade. The cutter body has generally hour-glass shaped opening defined by a circular loop opening and a blade opening that merge together through a narrow throat opening. The blade is situated so that the sharp beveled edge extends laterally into and across the blade opening opposite the throat opening and the loop opening. The loop opening provides a tie loop through which a neck tie is passed when the tie cutter is donned on a neck tie and worn. It also provides a finger loop for hooking and pulling the tie cutter with a finger to sever a neck tie from around the wearer's neck.

A remote assistance workstation 12 comprises a communications module 54, a user interface (UI) module 52, and a controller 56, for being coupled to a portable device 14 that includes a pair of augmented reality (AR) glasses 36 worn by a first responder to carry out an action using an object with a subject at a scene. The UI module 52 renders a remote assistant graphical user interface (GUI) 100 that includes (i) a first pane 96 for displaying a live video stream of a remote assistance request and (ii) a second pane 98 for displaying a 2D representation of the object at the scene being moveable therein by remote assistant inputs. The GUI 100 renders a corresponding item of 3D virtual content within the first pane relative to a reference point. The controller 56 outputs remote assistance signals to the portable device 14 for displaying the item of 3D virtual content 38 on the AR glasses in a live view of the scene, appearing at a location determined by the remote assistant inputs moving the 2D representation within the second pane 98 for assisting the first responder at the scene.

A body belt for use by linemen and others engaged in operations on poles or similar structures having a secondary set of D-rings, typically disposed slightly rearward of the primary D-rings on the belt or an auxiliary belt or attachment above or below the primary D-ring of the belt. The secondary D-rings which may differ in size from the primary D-rings, allow a wearer to separate devices that are normally attached to the primary D-rings. This allows less crowding of the primary D-rings, thereby making detachment and reattachment of one or more ancillary safety devices from the body belt as a lineman encounters an obstacle during his or her work on a pole or other elevated structure, thereby improving safety. An add-on D-ring assembly is provided for retrofitting body belts of the prior art. In another embodiment of the invention, an auxiliary body belt is detachably connected to the primary body belt, the auxiliary body belt having its own set of D-rings. Rather than providing all four D-rings in a common plane, as described above, this embodiment provides one plane for the first set of D-rings (on the primary body belt) and a second, parallel plane for the second set of D-rings (on the auxiliary body belt).

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.
