  • Patent number: 11215764
    Abstract: A modular optical connector includes a plurality of coupled optical ferrule support modules. Each optical ferrule support module comprises module connecting features configured to couple each ferrule support module with one or more neighboring ferrule support modules of the plurality of ferrule support modules. One or more optical ferrules are disposed and configured to rotate within the ferrule support module. Each optical ferrule includes a first attachment area configured to attach to one or more optical waveguides. One or more passageways are disposed within the ferrule support module. Each passageway is configured to receive the one or more optical waveguides. The passageway comprises a second attachment area configured to attach to the optical waveguides that are attached to the optical ferrule at the first attachment area. The passageway is dimensioned to constrain the optical waveguides to bend within the housing between the first attachment area and the second attachment area.

  • Publication number: 20210406154
    Abstract: Based on replay of a thread, one implementation observes an influx of a value of a memory cell comprising an interaction between the thread and the value of the memory cell at an execution time point in the replaying, and determines whether the value of the memory cell observed from the influx is inconsistent with a prior value of the memory cell as known by the thread at the execution time point. If so, this implementation initiates an indication of a data inconsistency. Based on replay of a plurality of threads, another implementation identifies a memory cell that was accessed by a first thread while a thread synchronization mechanism was active on the first thread. Then, if there was another access to the memory cell by a second thread without use of the thread synchronization mechanism, this implementation initiates an indication of a potential data contention.

  • Patent number: 11163122
    Abstract: An optical ferrule (200) has opposing major top (10) and bottom (20) surfaces where the bottom surface includes discrete spaced apart first (90) and second (100) platforms arranged along a mating direction of the optical ferrule (200). During a mating of the ferrule (200) with a mating optical ferrule (200?), the first (90) and second (100) platforms of the ferrule (200) slide against corresponding respective first (90?) and second (100?) platforms of the mating ferrule (200?). Upon full mating of the ferrule (200) with the mating ferrule (200?), the second platforms (100, 100?) of the ferrule and the mating ferrule remain in contact with and rest on each other, and the first platform (90, 90?) of neither ferrule makes contact with the other ferrule.

  • Patent number: 11086083
    Abstract: An optical connector (100) includes a housing (112) configured to contain one or more optical ferrules (121) disposed within the housing and accessible through an opening at a mating end of the housing. A cover (130) is disposed at the mating end, the cover configured to be rotated about a pivoting axis between a closed position an open position. An actuator (135, 136) is configured to cause the cover to rotate about the pivoting axis from the closed position to the open position.

  • Patent number: 11015040
    Abstract: Various embodiments disclosed relate to a resin including nanoparticles including surface-bonded hydrophobically-modifying alkyl groups. The present invention provides a resin component that includes a curable resin. The resin component also includes nanoparticles dispersed in the resin. The nanoparticles each independently include surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups. At least one of the (C1-C50)hydrocarbyl groups is a (C1-C50)alkyl group and at least one of the surface-bonded hydrophobically-modifying (C1-C50)hydrocarbyl groups is a (C6-C50)aryl group.
