  • Patent number: 9774392
    Abstract: Systems and methods using a polarimetric measurement device to localize a source of one or more State of Polarization (SOP) transients affecting one or more optical fibers are disclosed. The method includes transmitting a signal into a fiber in a first direction; receiving, at the polarimetric measurement device, the signal from one of the fiber and another fiber collocated in a bundle with the fiber in a second direction; and processing data from the polarimetric measurement device to determine a location of the one or more SOP transients. The processing can include detecting a presence of the one or more SOP transients based on a first signature and its echo seen in the data; and converting a time between the echoes into a distance.
    Type: Grant

  • Patent number: 8886356
    Abstract: Methods, devices, non-transitory storage media, and systems that utilize operations including configuring each feed conveyor in the plurality of feed conveyors to operate in a slug-building merge mode, monitoring to identify a first predefined condition, configuring each feed conveyor in the plurality of feed conveyors to operate in a zippering merge mode in response to identifying the first predefined condition, monitoring to identify a second predefined condition, and configuring a first set of the feed conveyors in the plurality of feed conveyors to operate in the slug-building merge mode and a second set of the feed conveyors in the plurality of feed conveyors to simultaneously operate in the zippering merge mode in response to identifying the second predefined condition.
