| 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. |
