  • Patent number: 9672594
    Abstract: A camera system for producing super resolution images is disclosed. The camera system may include a target scene, a first detector configured to capture a first image of the target scene, and a second detector configured to capture a second image of the target scene. The first detector may include a first pitch, and the second detector may include a second pitch different from the first pitch.

  • Publication number: 20160288924
    Abstract: A self-forming sealant system forms a seal between two parts or between a fastener and a part of a structure. In forming the seal, a first finish having a high surface energy is applied to the joint between the two parts or is applied to the fastener and the part. A second finish having a low surface energy is then applied adjacent to the area where the first finish was applied. A sealant is then applied to the joint between the two parts or the fastener and the part, where the sealant migrates to the joint or fastener coated with the first finish having the high surface energy and away from the areas adjacent the joint or the fastener coated by the second finish having the low surface energy.

  • Publication number: 20160257427
    Abstract: A method of fabricating a composite assembly may include providing a first laminate and a second laminate respectively formed of first and second composite plies, and having a respective first and second cured section and a respective first and second uncured section. The method may further include interleaving the first composite plies in the first uncured section with the second composite plies in the second uncured section to form an interfacial region. The method may additionally include curing the interfacial region to join the first laminate to the second laminate and form a unitized composite assembly.

  • Patent number: 9430814
    Abstract: A camera system for producing super resolution images is disclosed. The camera system may include a lens, a detector array configured to capture an image focused through the lens onto a focal plane, and a transducer coupled to one of the lens and the detector array. The transducer may be configured to impart motion to the one of the lens and the detector array over a predetermined time period, and the detector array may capture a plurality of images over the predetermined time period.

  • Publication number: 20160221829
    Abstract: In one aspect, methods of making semiconducting single-walled carbon nanotubes are described herein. In some implementations, a method of making semiconducting single-walled carbon nanotubes comprises providing a plurality of semiconducting nanotube seeds including (n,m) nanotube seeds and non-(n,m) nanotube seeds. The method further comprises illuminating the plurality of nanotube seeds with a first laser beam having a first wavelength and a second laser beam having a second wavelength, the second wavelength differing from the first wavelength. The first wavelength corresponds to an absorption maximum for a (n,m) carbon nanotube and the second wavelength corresponds to a photoluminescence emission frequency for the (n,m) carbon nanotube.

  • Patent number: 8445788
    Abstract: A conductive wire includes a metallic wire substrate having a diameter and a surface, and a coating material having a plurality of carbon nanotubes dispersed therein. The coating material is operable to adhere a portion of the carbon nanotubes to the surface of the wire. The coating material has higher specific conductivity than the metallic wire substrate and also has a low contact resistance with the metallic wire substrate.
