Abstract
An electronic automatic reserve or primary parachute activation device incorporates partial or complete capture of freefaller or tethered parachute jumper kinematics to rapidly and reliable determine when to automatically activate deployment of the primary or reserve chute. This device uses means for directly measuring acceleration, velocity and/or position in addition to air pressure change to enable reliable detection of chute deployment conditions earlier than is possible with conventional pressure change activated automated activations devices. This is important when the activation decision must be made within 5–10 seconds of the initiation of the jump as is the case for military low altitude parachuting.
