Sensored fiber reinforced polymer grate
| DWPI Title: Sensored grate for use in security fencing application, has grate framework including internal surface, where outermost layer of optical fiber is embedded in and fixed to elongated elements and fixed to internal surface of framework |
| Abstract: Various technologies described herein pertain to a sensored grate that can be utilized for various security fencing applications. The sensored grate includes a grate framework and an embedded optical fiber. The grate framework is formed of a molded polymer such as, for instance, molded fiber reinforced polymer. Further, the grate framework includes a set of elongated elements, where the elongated elements are spaced to define apertures through the grate framework. The optical fiber is embedded in the elongated elements of the grate framework. Moreover, bending or breaking of one or more of the elongated elements can be detected based on a change in a characteristic of input light provided to the optical fiber compared to output light received from the optical fiber. |
| Use: Sensored grate for use in a security fencing application. |
| Advantage: The grate has prolonged service life when polymers are nonporous and cured, and offers minimal degradation in corrosive environments. The grate minimizes optical signal loss and maintains the optical fiber away from walls of the grate framework by controlling placement of the optical fiber. |
| Novelty: The grate has an optical fiber (136) including an outermost layer embedded in and fixed to elongated elements (106, 114, 116) of a grate framework (102), where cross-sections of the optical fiber embedded in the elongated elements are in fixed contact with an internal surface of the elongated elements, and bending or breaking of the elongated elements are detected based on change in characteristic of input light provided to the optical fiber. The framework includes an internal surface, where the outermost layer of the optical fiber is fixed to the internal surface of the framework. |
