Abstract: A system and method for tagging, tracking, locating and identifying people and vehicles transporting people using Perfluorocarbon tracers. An on-going problem faced by military as well as law enforcement personnel is that of friendly fire incidents. To prevent possible friendly-fire incidents, troops would separate the two layers of the uniform patch, thereby releasing a controlled release of the Perfluorocarbon vapors. Other “friendly” troops, equipped with sensors tuned to the specific perfluorocarbon characteristics would thus be able to literally view a plume around the tagged person or object. The system may conversely be used to tag enemies. Formulations of mixed perfluorocarbons may be used to provide coding of emissions.

With such a control the projectile is able to be steered using bank-to-turn maneuvering. The actuator system may use any of a variety of mechanisms to move the lift-producing surfaces, thereby positioning the collar.

Abstract: A highly reliable fuse for explosives and armaments is achieved by employing a micro mechanical device that operates to disrupt a relatively low impedance bypass circuit coupled in parallel with a relatively high impedance trigger mechanism.

The micro mechanical device may be a micro-electrical mechanical system (MEMS) device and the bridge is at least one spring that is part of the MEMS device and also part of the bypass circuit.
