Abstract: A device includes a memory and a processor coupled to the memory operable to perform operations. The operations include determining a first estimated distance associated with a first location of an optical fiber based on first light detected by a sensor, where the first light is detected at a first time when a portion of the optical fiber has a first configuration, and determining a second estimated distance associated with a second location of the optical fiber based on second light detected by the sensor, where the second light is detected at a second time when the portion of the optical fiber has a second configuration. The operations further include determining a third estimated distance associated with a third location of the optical fiber based on the first estimated distance and the second estimated distance, where the third location is associated with a fault in the optical fiber.

Abstract: A beam deflection device including an aluminum disc containing a plurality of lasers, each laser projecting a laser beam substantially along one of the ‘X’, ‘Y’, and ‘Z’ axes of a structural beam to which the device is attached. Wiring is attached to each of the plurality of lasers to provide power and transmit data. Passageways are provided in the solid disc to route the wiring to the exterior. A suction cup on a surface of the device allows it to be attached to the beam by pressing the device against a flat surface area of the beam.
