A flotation device for providing emergency flotation for a person swimming or passing through a body of water, comprising a container filled with a charge of a gaseous material under a pressure such that it is in its liquid phase at normal environmental temperatures. The container is connected to a flexible flotation chamber through a passage which remains normally closed until actuated by the user. When the device is actuated by opening the passage, the charge expands into the flotation chamber, thereby inflating it, and providing support to the user in the water. The gaseous material has thermodynamic properties such that it remains in its liquid phase right up to the maximum temperatures to which the device is expected to be exposed to. Consequently, its volume, and hence the internal pressure within the gas container, does not increase significantly, thereby enabling the container to be of lightweight construction.

A lower body garment that includes an inflatable flotation device and a method of using the garment for flotation are provided. The flotation device is integrated with the garment and can be inflated in case of emergency in water. The garment is designed to be worn as a typical lower body garment when the flotation device is deflated and to convert into a life jacket that can be harnessed to a user's upper body and inflated to provide flotation. The garment includes straps that are designed to be used as both a garment belt when worn on the lower body and as harness straps when used for flotation.

A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve.

Flexible lifesaving devices, such as life vests, pilot suits, lifeboats, lifebuoys, providing flotation to their users. An internal inflation space, integral to the device, has a volume sufficient when inflated, to provide flotation to a person or persons having up to a predetermined weight, using the device. Pressurized flotation gas, having a volume in its gaseous phase sufficient to inflate the internal space, is contained in a flexible pressurized gas container, such as a length of tubing or a pouch in a wall of the device, and enables the device to be both flexible and foldable. A valve connects the flexible container with the internal inflatable space of the device, such that when the valve is opened, the volume of pressurized flotation gas flows into the internal space. The flexible container is a regulatory required part of the device, which is thus flexible and foldable.

A self-inflating wetsuit includes two (2) air chambers within the chest area of the wetsuit. A canister of compressed air is attached to the wetsuit and in fluid communication with the air chambers. The wetsuit has an integrated thermometer capable of reading the temperature of the environment inside and outside the wetsuit. The wetsuit has a battery-operated warming feature and an integrated GPS system so that the wetsuit may be accurately located.

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.

An aquatic system is provided for use with an object. The aquatic system includes: a parameter detector being configured to detect a parameter of the object and to output an activation signal based on the detected parameter; an inflatable bladder being configured to inflate with a gas to displace a volume of water when the object is in the water; a memory having instructions stored therein; and a stabilization controller being configured execute the instructions to cause the inflatable bladder to inflate so as to establish horizontal buoyancy of the object based on the activation signal.

The present invention provides a system for the supporting and the containment of a person, which system comprises an inflatable exoskeleton structure, and an inflatable containment structure for said person. The exoskeleton structure is substantially soft and flexible when in the non-inflated condition and is easily worn by the user, and once worn it can be inflated for submersion in water to provide the required buoyancy support to the user. When the inflatable containment structure is in the deflated condition it is completely collapsed and may be contained in a bag or backpack, and when it is in the fully inflated condition it can accommodate and support the injured person therein in a blocked manner by containment means of said person in said containment structure.

A submarine escape cold weather survival suit includes a facial hood or dome pneumatically connected to a principal body cavity and additional pneumatically connected extensions to fit body extremities and a coverable cranial opening. The structure of the suit includes a layered structure of mechanically interconnected suits within suits. A composite of tear-proof and insulation material forms an internal suit or first envelope that is surrounded by a waterproof suit and then by a tear resistant suit. An optional pneumatic tube may be used.
