Abstract: A security bar providing improved security from breach is obtained with the use of a fiber optic cable longitudinally inserted in a hollowed out cavity thereof. Monitoring of the security bar to identify attempts at breach thereof may be achieved by connecting an optical light source to one end of the fiber optic cable and a light monitoring device (i.e., an optical receiver) at the other end. In this manner, a breach of the security bar is identified when the optical receiver fails to receive the light generated by the optical light source. In one embodiment, an isolator which consists of a material that is soft enough to absorb a potential shock but hard enough to break or splinter if the security bar is substantially deformed (e.g., wood) surrounds the fiber optic cable.

Abstract: A sheet includes an optical fiber extending across at least a portion of its surface to detect nuclear radiation. The sheet can line at least a portion of a shipping container or box. Radiation within or outside the container or box reduces optical transmissibility of the fiber. The fiber integrates the radiation over time and/or over the length of the fiber, making the fiber sensitive to even low-level radiation. Dopants, use of particular wavelengths of light or temperatures or other mechanisms can increase the sensitivity of the optical fiber to radiation. The optical fiber is monitored for a change in its transmissibility. A reduction in the transmissibility, such as to below a threshold, can trigger an alarm, such as an annunciator, or send a message that includes information about the time or the container's contents or location when the radiation is detected to a central location, such as a ship's control room or port notification system.

Abstract: Closely spaced conventional optical fibers are arranged in a grid placed between a first surface and a second surface. A penetrating impact onto the first surface results in a hole of a size proportional to the diameter and velocity of the impacting object. The size and shape of the debris plume that travels between the first and second surfaces is also proportional to the diameter and velocity of the impacting object. If the debris plume is sufficiently energetic, a number of the fibers in the grid are broken. The size and shape of the area defined by the broken fibers can be determined simply by determining which fibers are no longer transmitting light. Analytical methods are then used to relate the extent of the damaged area to the location of an MOD impact, the direction from which the impact occurred, and the size of the impacting object.

Abstract: A liner sheet lines at least a portion of an interior surface of a shipping container or box and defines an optical path extending across at least a portion of the sheet, such that a breach of the interior surface also alters an optical characteristic of the optical path.
