Pressure Gauge
- Summary
- A pressure gauge includes a housing and a mechanical sensor placed in the housing for sensing change of the pressure. A characteristic of the sensor varies in correspondence to the change of the pressure. The gauge also includes an optical fiber, at least part of which is in the housing with a first end connected to the sensor such that a characteristic of the fiber varies in correspondence to the variance of the characteristic of the sensor, and an optical signal generator connected to a second end of the fiber for emitting an optical signal into the fiber. The second end of the fiber is distanced from the sensor, and the fiber generates at least a first reflected optical signal towards said second end, which first reflected optical signal contains information relating to the variance of the characteristic of the fiber. The gauge further includes an optical signal analyzer connected to the second end of the fiber for receiving and analyzing the first reflected optical signal for ascertaining the change of the pressure based upon the information contained in the reflected optical signal.

Title: Systems, methods, and apparatus for structural health monitoring
Usefulness: Systems, methods, and apparatus for structural health monitoring
Summary: Method for monitoring a structural health of the structure e.g. aircraft bodies. Can also be used for composite-based structures, such as boat hulls, concrete structures such as roads, buildings, reservoirs, pipes, and wells, metal-based structures such as framing, structural supports, building supports and body panels, composite materials such as fibermatrix composites, reinforcement-plus-filler hybrid composites, fiber-plus-particle hybrid composites and composite laminates.
Novelty: Method for monitoring structural health of structure e.g. aircraft bodies, involves providing analyzer in signal communication with nano-optoelectronic rods, and receiving electrical signal at analyzer from rods
