    Abstract: An apparatus comprises a flexible filament structure, and a fiber optic sensor with a buffer material that locally bonds the fiber optic sensor to the flexible filament structure to create a bond between the fiber optic sensor and the flexible filament structure to transfer strain from the flexible filament structure to the fiber optic sensor to allow the fiber optic sensor to detect strain on the flexible filament structure while maintaining flexibility in the flexible filament structure. A fiber optic interrogator may be optically coupled to the fiber optic sensor and configured to measure strain. A method comprises embedding a fiber optic sensor with a buffer material in or on a flexible filament structure. Thereafter, the buffer material is activated via heating or curing to locally adhere the fiber optic sensor to the flexible filament structure to create a local bond. The local bond transfers strain from the flexible filament structure to the fiber optic sensor.

    Abstract: One example coherent optical time domain reflectometer device includes a coherent light source that produces coherent probe light pulses at an optical wavelength; an optical coupling unit coupled to f a fiber link under test to direct the coherent probe light pulses into the fiber link and to receive reflected probe light pulses from the fiber link; an optical detection unit to receive the reflected probe light pulses and structured to include an optical interferometer to process the reflected probe light pulses along two different optical paths to generate different optical output signals from the reflected probe light pulses along different optical paths, and optical detectors to receive the optical output signals from the optical interferometer; and a device controller coupled to the optical detection unit to extract information on spatial distribution of acoustic—or vibration—or strain-dependent characteristics as a function of distance along the fiber link under test.

    Abstract: The present disclosure relates to optical switching devices and switch modules that are designed for long-term security monitoring of high-value infrastructure access entry points. Embodiments in accordance with the present disclosure include optical switches based on fiber-Bragg gratings whose operating wavelengths are based on the presence or absence of magnetic coupling between an embedded permanent magnet and an external element. By monitoring the spectral position of the operating wavelengths and/or the magnitude of a light signal at the operating wavelengths, the state of the magnetic coupling can be determined and used as an indicator of whether the security switch has been actuated.

    Abstract: An optical sensing fiber includes multiple reference reflectors spaced along a length of the fiber. Each of the multiple reference reflectors producing a reference scattering event having a known scattering profile including an elevated amplitude relative to scattering detected for neighboring segments of the optical fiber. Each of the segments is a length of contiguous fiber that is useable to initialize and perform a distributed Optical Frequency Domain Reflectometry (OFDR) sensing operation. An OFDR interrogation system is disclosed that measures a parameter using the optical sensing fiber.

    Abstract: Medical training kits and methods include a simulated liquid blood which simulates mammalian whole blood and a simulated hemostatic component. The simulated liquid blood includes a gellable component, and a simulated hemostatic component includes a gelling agent. The gelling agent causes the gellable component in the simulated liquid blood to form a mass of semi-solid or solid material in response the simulated blood being brought into contact therewith to thereby simulate blood clotting. In certain embodiments, the gellable component is chitosan and/or an alginate compound and the gelling agent is at least one compound which causes the gellable component to desolubulize, polymerize, complex, precipitate, cross-link and the like so as to form a semi-solid or solid mass of chitosan in response to physical contact between the simulated blood and the simulated hemostatic agent.

    Abstract: A corrosivity associated with each of multiple locations near, on, or within a structure exposed to an environment that can corrode the structure is determined. Each of multiple sensor nodes is mounted at a corresponding one of the locations and measures environmental sensor information using one or more environmental sensors and corrosion sensor information using one or more corrosion sensors. The environmental sensor information is processed to obtain for the sensing node a first atmospheric corrosivity category value in accordance with a corrosivity classification system, and the corrosion sensor information is processed to obtain a second atmospheric corrosivity category value for the sensing node in accordance with the corrosivity classification system. One or more of the first and second atmospheric corrosivity category values is provided for use in determining a corrosion classification value for each of the locations.
