A safety, rescue, and recovery device that compressively secures to a limb of a user when inflated. The device can be easily adjusted to be negatively buoyant, neutrally buoyant, or positively buoyant before inflation depending on whether the application is safety, rescue, or recovery. The device may also be integrated into an article of clothing for certain applications. An elongated handle is attached to the device to provide a sliding attachment point for a rescue rope that automatically reduces torque applied to the limb of the user. Consequently, a rescue force applied to the rescue rope can act at a variety of angles along an arc relative to the device.

A high flow rate inflator intended to be threaded into or onto the threaded neck of a conventional gas cylinder. The inflator comprises a spring-loaded ballasted firing pin that is retained in a cocked position by a tethered trigger pin. Upon firing by pulling on the trigger pin, the firing pin forcibly moves into engagement with a power primer mounted with a power primer holder to ignite the same, whereupon the ignition gases forcibly drives a hollow larger diameter pierce pin mounted within an interior cylinder into the frangible seal of the gas cartridge to cut a large-bore hole therethrough and allow gas escaping from the gas cylinder to flow at a high rate through the inflator into an inflatable device.

A persona! flotation device for a user comprises a bodywear member, as well as a container containing buoyant gas and an actuation assembly, both of which are mounted to the bodywear member. The bodywear member is to be worn to by the user such as on the wrist or the neck. The actuation assembly is in operative communication with the container containing buoyant gas for selectively being actuated so as to provide fluid communication between the container containing buoyant gas and the inflatable member. Actuation of the actuation assembly provides for releasing the buoyant gas into the inflatable member causing the inflatable member to inflate and provide buoyancy to the persona! flotation device.

The present invention provides a perforator for breaking a closing member at a gas outlet of a gas bottle to allow a gas to flow out, including the cylindrical housing having three openings, namely, a first opening at a first end portion, a second opening at a second end portion which is opposite to the first end portion, and a third opening formed in a circumferential wall portion, an ignition device being fixed at the first opening, the second opening to be connected to the gas bottle and the third opening serving as a gas discharge portion, an first piston and a second piston being disposed, in the order of the first piston and the second piston, from the side of the ignition device to the side of the second opening in the cylindrical housing, and when a pressure created by actuation of the ignition device is received, the first piston moving in an axial direction inside the cylindrical housing, and the second piston moving towards the second opening inside the cylindrical housing by receiving the movement of the first piston.

This invention discloses an inflator mechanism for rafts and life vests that performs a multitude of functions required for rescue and underwater deployment of personnel and devices. The inner cylinder in this disclosure is actuated by a plethoria of inputs, manual, automatic selectable pressure sensing, or dualled hydrostatic sensors which can each be safely selected by function selection. Since the inflator uses spring discs to drive a penetrator which mechanically punctures a membrane of an inflation gas source and actuated by an electronically controlled solenoid, dissolvable elements, conductivity switches and preset check valve actuators are eliminated increasing the safety and reliability of the actuator. Electronic control further permits user enabling of inflation depth actuation and the multiple water sensors prevent failure of actuation due to splashes and humidity effects on sensors. The actuator mechanism is self cocking, indicates proper installation of gas source enables use of several gas source cylinders and is multiply reusable.
