Abstract: A life raft is provided having a base having a top side and a bottom side, one or more buoyancy elements attached to the top side of the base, and a righting-device attached to the bottom side of the base, the righting-device is configured to shift a center of gravity of the life raft. When the life raft is subject to an instability event, the righting-device is configured to provide a shifted center of gravity such that a righting moment is generated to automatically return the life raft to an upright position.

Abstract: An upper smart arch extends upwardly from an inflatable upper tube and a lower smart arch extends downwardly from a lower inflatable. An orientation sensing transfer valve is located at each interface of the upper smart arch and upper tube and a lower orientation sensing transfer valve is located at each interface between the lower smart arch and the lower tube. Deployment of the upper smart arch along with an upper canopy will be deployed with the opening of the upper orientation sensing transfer valve and the lower smart arch and a lower canopy will not be deployed since the lower orientation sensing transfer valve remains closed.
