A personal flotation device is provided that includes a housing, a canister disposed within the housing and storing a compressed gas, an inflatable member coupled to the housing, a channel within the housing, and a compressible member positioned within the channel. The channel extends from an exit point of the canister to the inflatable member such that the canister can be in fluid communication with the inflatable member. The compressible member is configured such that (i) when the personal flotation device is located less than a predetermined depth below a surface of water, the compressible member prevents the compressed gas from the canister from reaching the inflatable member, and (ii) when the personal flotation device is located greater than or equal to the predetermined depth below the surface of water, the compressible member compresses and thereby allows the compressed gas from the canister to inflate the inflatable member.

A system including a flotation mechanism incorporated into a chassis or framework constituent of a vehicle, the flotation mechanism is operable for protecting a vehicle from losses in cases of vehicle drowning accidents; an airbag implement for keeping the vehicle afloat or above water; a cylinder implement for housing the airbag implement, wherein the cylinder implement having two half cylinders that is configured to swing open when activated; a hinge implement including a continuous hinge that is configured to hold the two half cylinders together and allow the two half cylinders to swing open; and a sensor implement for detecting a presence of water or liquid flooding a vehicle, wherein the sensor implement is further configured to send an emergency signal the flotation mechanism, for the flotation mechanism to deploy the airbag implement.

In order to provide a small life jacket that is unlikely to obstruct movement of a wearer, a life jacket includes: a float member that changes from an uninflated state to an inflated state with gas being supplied to an internal portion thereof; a cover that covers the float member in the uninflated state; a connecting member and a waist belt as a wearable member that is to be worn by a wearer; a guide member that is linked to the connecting member and the waist belt; and a slidable member that is linked to the float member and that slides along the guide member.

A liquid-ingress control device, comprising a casing having an interior and an exterior, and optionally, a liquid-activated trigger positioned in the casing interior, the casing comprising an exterior liquid entry control surface defined by a perimeter in sealing relationship with an edge of a cap, the cap having an interior cap surface formed to define a cap space between the interior cap surface and the liquid entry control surface; the liquid entry control surface comprising a liquid entry port comprising a tube extending between the exterior and interior of the casing through an aperture formed in the entry control surface, the tube optionally comprising a flange positioned exterior to the casing; the cap comprising at least two flow apertures positioned such that liquid contained within the cap space is capable of egress under gravity from the cap space, independently of the orientation of the device.

An emergency flotation harness that provides for a water-activated flotation vest for a pet such as a dog, that automatically self-inflates when exposed to water such as a pool, lake, pond, river to protect the pet from drowning. The harness would be worn by a pet and made available in multiple sizes such as small, medium, large, and extra-large to fit a wide variety of pets of different ages and sizes. The harness would be made of multiple sections of straps, such as waterproof nylon. To further allow for exact sizing, the harness would consist of multiple adjustment clips, to allow for adjustment of the straps to exactly fit the pet or as it grows.

It is a portable cover for lifebuoys that facilitates their transport due to its small size, while its velcro-type closure make possible enough resistance to allow for expansion when the lifebuoy is activated by a sensor-actuator, when contact with the water is made.

In order to provide a small life jacket that is unlikely to obstruct movement of a wearer, a life jacket includes: a float member that changes from an uninflated state to an inflated state with gas being supplied to an internal portion thereof, a cover that covers the float member in the uninflated state; a connecting member and a waist belt as a wearable member that is to be worn by a wearer; a guide member that is linked to the connecting member and the waist belt; and a slidable member that is linked to the float member and that slides along the guide member.

A wearable flotation device. The wearable flotation device includes a garment having an interior volume that can receive a bladder therein, wherein the bladder is designed to receive a compressed gas to enable flotation of a wearer of the garment in a body of water. A deployable signal is operably connected to the bladder via a tube having a sensor, wherein the sensor can actuate a one-way valve upon detection of moisture. The one-way valve is designed to enable the flow of the compressed gas, whereby the compressed gas actuates the deployable signal upon the sensor's detection of moisture. When actuated, the deployable signal extends upwardly beyond a periphery of the garment to alert a nearby individual of the wearer's location in the event of an emergency. The garment further includes a plurality of lights thereon for illuminating the wearer to assist in identifying the wearer's location.
