Abstract
An automated quick release mechanism for a three ring release includes a pneumatic or hydraulic cylinder with a hardened metal pin. The pin engages a string loop of the three ring release. An internal spring holds the pin in an extended position. A controller external to the automated quick release mechanism provides a gas or fluid pressure to withdraw the pin and disengage the string loop.
