Abstract:
A compressed air powered long-range life saving device is provided. Compressed air in an air canister flows to project a tube, a rope within the tube extends to unfasten a safety pin, a sliding disc pushes down a first needle until stopped, the first needle punctures an auxiliary air canister to release compressed air, the compressed air enters a receptacle, the compressed air flows out of the receptacle into a first portion of a second cylinder, the second needle is pushed down when the pressure reaches a preset value, the second needle punctures a main air canister to release compressed air prior to entering a second portion of the second cylinder, the compressed air flows out of the second portion into the first cylinder, the compressed air flows into the a lifebuoy for inflation, the inflated lifebuoy separates a housing into two pieces, and the rope unwinds.
Abstract:
The present invention offers a solution to the potential hazards associated with an accidental overheating of a full compressed gas cartridge, by offering an automatic heat-actuable pressure discharge system. The compressed gas cartridge is protected from dangerous explosions caused by excessive heat by the use of a lance that pierces the compressed gas cartridge safely when a spring loaded hammer is released from its constraints when a length of heat sensitive material fails in the presence of excessive heat, thereby avoiding a very serious fire hazard.
Abstract:
The present invention relates to a water floatation garment, and in particular, to such a swimming garment incorporating a fillable bladder and electronics provided to identify emergency situation such as drowning based on sensed data that causing the garment to trigger the fillable bladder to inflate allowing a user to float to surface therein preventing a drowning.
Abstract:
An inflation device for storing and releasing pressurized fluid includes a substantially donut shaped cylinder (2) containing the pressurized fluid. An activation system (4) includes a trigger mechanism (6) positioned within a cavity (8) formed by the donut shaped cylinder (2). The cylinder (2) includes at least one puncturing zone (3) in contact with the pressurized fluid, the puncturing zone (3) including a sealing element (33) seated on a valve member inside the puncturing zone (3), the sealing element (33) connected to a puncturing rod (31). When activated, the trigger mechanism (6) actuates the puncturing rod (31), driving the sealing element (33) off the valve member thereby allowing the pressurized fluid to flow out of the cylinder (2) past the sealing element (33) and through the puncturing zone (3).
Abstract:
Embodiments provide a swimming assist garment capable of adjusting buoyancy positions. In the embodiments, the swimming assist garment includes a swimsuit, a buoyancy mechanism, and a gas regulating mechanism. The inflatable end of the gas regulating mechanism is connected to first airbags of a first buoyancy assembly and a second airbag of a second buoyancy assembly. The first bidirectional air pumps are connected to each first airbag and each third airbag of the first buoyancy assembly; and a second bidirectional air pump is connected to the second airbag and the fourth airbag of the second buoyancy assembly, to change the buoyancy positions of the swimsuit to adapt to swimming postures or to support the head on the water.
Abstract:
A personal flotation device capable of providing buoyancy and preventing hypothermia and death caused by loss of body heat by supporting the individual's entire body out of the water. Special design features increase the ease of use to ensure successful deployment and boarding, even among injured, weak, and/or physically exhausted individuals. This personal flotation device is small and compact, so that it may be used in a prophylactic manner from low-risk to high-risk applications.

Abstract:
A flotation device that can include a multi-chamber flotation element having a first fluid chamber and a second fluid chamber. The flotation device can have a first valve in fluid communication with the active inflation chamber but not the passive inflation chamber and an opening in fluid communication with the passive inflation chamber but not the active air chamber. The active inflation chamber can be configured to be inflated through the first valve. The active inflation chamber can be configured to expand the passive inflation chamber from a collapsed state to an expanded state as the active inflation chamber is expanded by, for example and without limitation, permitting ambient air to enter the passive inflation chamber when a pressure within the passive inflation chamber is less than an ambient air pressure.
Abstract:
A short-range life saving device is provided. After removing a safety pin and throwing a housing, a wound portion of a line unwinds, a spring loaded sliding disc pushes down a first needle until being stopped, the first needle punctures an auxiliary air canister to release compressed air, the compressed air enters a receptacle, the compressed air flows out of the receptacle into a first portion of a second cylinder via an axial hole, a second needle is pushed down when the pressure reaches a predetermined value, the second needle punctures a main air canister to release compressed air prior to entering a second portion of the second cylinder, the compressed air flows out of the second portion of the second cylinder into the first cylinder, the compressed air flows into a lifebuoy for inflation via a tube, and the inflated lifebuoy separates the housing into two halves.
Abstract:
A carbon dioxide cartridge is triggered when a lance with a piercing tip punctures its burst disc. The cartridge has a cap that has an outlet and a passage for the lance and puncturing tip to travel. The lance is pushed into the burst disc when a heat expanding substance which is stored hermetically the cap in such a way that the only direction to expand is to displace and push the lance right into the burst disc. Once the burst disc is pierced, the cartridge empties its contents quickly out the outlet. In at least one embodiment the cartridge and the cap are attached by screw threads.
