    Abstract: An actuator, a release device, and a method of actuating a release device are provided. The actuator comprises a housing defining a first path; an actuating element disposed within the first path, the actuating element being made from a shape memory alloy having a transition temperature, the actuating element being configured to couple with a power source, at least portion of the actuating element being further configured to not change shape when the power source applies a first current for a predetermined amount of time and moves at least a portion of the actuating element from the first position to a second position when the power source applies a second current; and a heat transfer material disposed in the first path between the actuating element and the housing.

    Abstract: A coreless-coil shock tube package system includes a “coreless” bundle of shock tubing, meaning that the tubing is not wrapped around a spool. The bundle may be a generally cylindrical coil of shock tubing. Optionally, two washer-like end plates abut the ends of the tubing coil for axial support. A self-adhesive tape covering partially covers the coil and end plates. A detonator is attached to one end of the tubing and lies tucked into the coil, through an end plate, for storage and transport. An igniter is attached to the tubing's other end. In use, the detonator is removed from the coil and attached to an explosive device. Then, the package is pulled away from the detonator and explosive, thereby uncoiling the tubing through the end plate for deployment. The igniter is actuated for igniting the shock tubing and activating the detonator and explosive.

    Abstract: Separation device assemblies are provided. The assemblies include a first plate defining respective contact surfaces and engagement surfaces and a second plate defining a respective contact surfaces and engagement surfaces. A fracture groove is located on separation walls of the first and second plates. A first end member, a second end member, and the separation wall of the first plate define a first plate expansion device channel and the second plate defines a similar second plate expansion device channel. When assembled, the first plate and the second plate form an expansion device cavity and the first and second plates form a frangible joint. The respective engagement surfaces are configured to engagement with receiving channels of attachable mounting devices.

    Abstract: Separation device assemblies are provided. The assemblies include a plurality of first segment elements, each first segment element having an attachment portion and a frangible portion, the attachment portion of the first segment elements is arranged to fixedly connect to a first structural component and at least one second segment element having an attachment portion and a securing portion, wherein the attachment portion of the at least one second segment element is arranged to fixedly connect to a second structural component. At least two of the plurality of first segment elements are attached to the at least one second segment element adjacent to each other and a first segment joint is formed between adjacent first segment elements. An expansion device cavity is formed between the attached first and second segment elements.
