What is an "automatic activation device"?

An automatic activation device is a mechanism that triggers an action without needing manual control. It works by sensing specific conditions or inputs, such as speed, altitude, or pressure, and then automatically performs a task, like opening a parachute or releasing a target. These devices are commonly used in activities where precise timing or safety is essential, helping to ensure that actions occur at the correct moment or in response to certain changes.
