Thanks guys for the information! I also have been contacted by a manufacturer who wants to help. If it's not possible, it maybe can be done with an accelerometer detecting free-fall.

Hello, I need some information about automatic openers. I already found some about Vigil, Cypres and Argus. But I need an other working. Openers like Vigil, Cypres and Argus activate at a fixed height. Unfortunately, I need a device that activates when a body reaches a certain rate of fall. It will be used in a recovery system for a UAV* (when the motor has a breakdown). So the opener has to be activated as soon as possible. thanks... *UAV = Unmanned Aerial Vehicle e-mail: [email protected]
