Electronic water-activated parachute release and life vest inflator

摘要

An electronic water-activated package is described for automatically releasing a parachute canopy and inflating a life vest upon immersion in water. Separate electronic water-activated packages are incorporated into frames of break away webbing releases securing the parachute canopy to the parachute harness, and into inflating assemblies located at the bottom of each lapel of a life vest. The electronic water-activated package includes an explosive squib and water sensing circuitry which both detonates the explosive squib and minimizes current leakage from a power supply also contained in the electronics package.
