A buoyancy generator for a vehicle may include a housing detachably mounted on a vehicle, a buoyancy generating unit mounted in the housing and including a tube configured to be inflated and deployed to an outside of the housing and a gas supply connected to the tube and configured to supply inflation gas to the tube during operation, and a handle unit provided in the housing and having a handle to be operated to deploy the tube so that the tube floats to a water surface due to buoyancy of the tube to allow an occupant gripping the handle to float to the water surface together with the tube.

Summary, the system is a 3D pop-up or pop-out survival system. The system sometimes involves a device that is worn on a person. The device potentially includes an activation button that, when pressed, releases an inflatable or memory spring pop-up/pop-out.

Networkable digital life jackets and associated methods are disclosed. An example life jacket includes a state manager and a swarm manager. The state manager is configured to selectively operate the life jacket in one of multiple operational states of the life jacket based on data obtained from one or more sensors of the life jacket. The swarm manager is configured to form a swarm network including the life jacket and one or more other life jackets.

An apparatus that facilitates search and rescue, for example, in open water. The apparatus comprises a substrate with a particular geometry and a perimeter. The apparatus further comprises a cover positioned atop the substrate with the cover also having a particular geometry and perimeter, which correspond to the geometry and perimeter of the substrate. An air-tight seal seals the substrate perimeter to the cover perimeter and creates a sealed internal region. A breakable vessel holding an illuminable dye located in the sealed internal region, along with an activator that is also located in the sealed internal region. When the breakable vessel is broken, the illuminable dye reacts with the activator and illuminates the illuminable dye.
