  • Optical surface strain measurements for pipe integrity monitoring
    Patent number: 11976916
    Abstract: An optical strain gauge system measures strain on the exterior surface of a pipe to identify areas of wear on the interior surface of the pipe. The optical strain gauge system comprises an optical sensing interrogator and at least one optical fiber. The optical sensing interrogator comprises a light source and a light sensor. The at least one optical fiber includes fiber Bragg gratings along the length of the optical fiber. The optical fiber is arranged on the exterior surface of the pipe with the fiber Bragg gratings forming a two-dimensional array of points at which strain measurements are obtained. The two-dimensional array of strain measurement points provides an accurate assessment of the strains on the exterior of the pipe which can be used to identify areas of wear on the interior surface of the pipe.

  • Systems and methods of providing redundant communication to an electronic device
    Publication number: 20050232145
    Abstract: In at least some embodiments a system may comprise a first master device, a second master device, a redundancy manager coupled to the first and second master devices, and a slave device coupled to the redundancy manager. The redundancy manager is operable to receive a first data stream from the first master device and a second data stream from the second master device. The redundancy manager is further operable to selectively forward one of the first and second data streams to the slave device according to a prioritization of factors calculated to optimize an amount of valid communication to the slave device.
