Definitions

  • Embodiments of the present invention relate to life jackets for marine applications. More particularly, the embodiments relate to auto-inflation systems for life jackets.
  • the present systems may inflate when a user is standing on the deck of a ship during heavy rain. Additionally, the system will inflate immediately if a user enters the water.
