A life raft may comprise a border tube and a canopy support tube coupled to an outer portion of the border tube. A first orifice defined by the canopy support tube is aligned with a second orifice defined by the border tube. A diameter of the first orifice is less than a diameter of the second orifice.

Provided is a maritime overboard locator system for use in locating and rescuing a person or asset that has fallen overboard into a body of water. The system includes a locator attached to a person or asset that is activated manually or automatically upon immersion in water. The apparatus emits light, sound, radio, or any combination thereof. The locator is detected by one or more detectors onboard a boat, ship, vessel, or structure. The detectors detect a unique signal that is assigned to each person/asset. Once detected, the detector sends an overboard alert and deploys an unmanned aerial or underwater drone. The drone can include an inflatable life preserver or life raft and a tether cord that helps the person to remain afloat until rescue can be accomplished.

An evacuation system may comprise a first plurality of tubes configured to inflate by an aspirator and pressure cylinder upon deployment from an aircraft. The evacuation system may further comprise a second plurality of tubes coupled to the first plurality of tubes. The second plurality of tubes may be configured to be in deflated state when the evacuation system is in a slide configuration. The second plurality of tubes may be configured to be in an inflated state when the evacuation system is in a raft configuration.

A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.

An orientation valve, in accordance with various embodiments, is disclosed herein. The orientation valve may comprise a first coupling portion, an insert portion, a second coupling portion, an internal cavity, and a piston. The insert portion may have a first inlet aperture and a second inlet aperture. The second coupling portion may be disposed between the first coupling portion and the insert portion. The internal cavity may be coupled to the first inlet aperture and the second inlet aperture. The piston may be disposed within the internal cavity. The orientation valve may be configured to block fluid flow from a compressed fluid source when an evacuation system is in a stored position. The orientation valve may be configured to fluidly couple the compressed fluid source and the evacuation device when the evacuation system is in a deployed position.

A system for inflating an inflatable device includes a ducted fan aspirator coupled to the inflatable device and having a fan and a fan motor configured to drive the fan to direct first air into the inflatable device. The system further includes a compressor aspirator coupled to the inflatable device and having a compressor and a compressor motor configured to drive the compressor to direct second air into the inflatable device.

A life raft may include a base comprising a first side and a second side, and a self-supporting, collapsible spring canopy. The canopy may include a spring wire frame, a first panel circumscribed by the spring wire frame, and a second panel circumscribed by the spring wire frame.

A boarding apparatus for use on a flotation device, in accordance with various embodiments is disclosed herein. The boarding apparatus comprises a stirrup ladder. The boarding apparatus may be integral to a lifeline assembly of the flotation device. The boarding apparatus may be removably coupled to a loop patch of the flotation device. The boarding apparatus may release from the loop patch and become a boarding configuration for the flotation device.

A sea anchor includes a textile tube and a resiliently flexible support. The textile tube may include a first end and a second end. The first end may have a rim defining a mouth and the second end may be closed. In various embodiments, the resiliently flexible support is coupled to the first end of the textile tube. The resiliently flexible support, in response to the sea anchor being deployed, may be configured to expand the mouth and retain the mouth open. In various embodiments, the textile tube has a conical shape, with the mouth of the first end being a base of the conical shape and the second end being a point of the conical shape. The resiliently flexible support is a ring coupled to the rim of the first end of the textile tube, according to various embodiments.

An evacuation slide may comprise an inflatable side rail extending from a head end to a toe end of the evacuation slide. A lifeline-geometric restraint may be coupled to the inflatable side rail. A restraint pin may be coupled to the lifeline-geometric restraint. A first loop may be coupled to a first location on the evacuation slide. A second loop may be coupled to a second location on the evacuation slide. The first loop may be configured to receive the second loop and the second loop may be configured to receive the restraint pin when the evacuation slide is in a folded position. The restraint pin may be configured to translate out the second loop in response to an internal pressure of the evacuation slide exceeding a predetermined internal pressure.
