ABSTRACT:
A pyrotechnic release mechanism is actuated by an electrical signal from a remote telemetry actuator such as a radio transmitter to cause two normally connected parts to separate. When used as shown with an animal collar mounted data acquisition system, the two parts can be separated to release the collar. If desired, a separate data storage device can be released to permit stored data to be recovered. The device comprises two parts with interfitting members normally held in position with a coupling pin. A pyrotechnic device is positioned behind the pin, and upon firing, the pin is moved sufficiently to clear one of the members at least, so that the two members will then separate. The device can be used to permit remotely controlled recovery of a part that is normally mounted together and which are to be separated. The movement of the separating pin after actuation can also be used for energizing a transmitter or signaling circuit that will send out a locator signal to simplify retrieval of the parts to be recovered. The linear actuation of the separating pin ensures simplicity of operation and reliability.
