Latest Patents

Hetzel holds a patent for an "Electromagnetic restraint release device, system and method." This invention enables actuation of a release function without relying on chemically energetic or thermally sensitive devices. Instead, it employs an electromagnetic (EM) force to mechanically separate components of a fastener. The system utilizes a pulsed power mechanism with a capacitive discharge circuit to generate an electric current pulse, which creates the necessary EM force. This force acts on a retaining wire that holds a segmented fastener intact. By increasing the length of the retaining wire, the device allows the segments to separate, effectively releasing the restraint mechanism. Notably, this technology does not require periodic recertification or replacement of energetics, reducing risks associated with heat soak in thermally sensitive devices during operational scenarios.
