  • Patent number: 11067063
    Abstract: An actuating device and a method for manufacturing an actuating device, where the method includes wrapping a conductive wire (204) around a polymer fiber (202) at a set tension, and heating the polymer fiber and wire to a temperature that exceeds the glass transition temperature of the polymer fiber for a predetermined amount of time to partially embed the conductive wire into the polymer fiber. The method also includes cooling the polymer fiber and wire to below the glass transition temperature resulting in a wired polymer fiber wherein at least part of the conductive wire is embedded in the polymer fiber.

  • Patent number: 6583335
    Abstract: A genetic transformation system via the pollen tube pathway is presented, plasmid DNA prepared with each of 4 different methods was applied to the surface of an ovary wound site after removal of the style of florets following pollination. Movement of the plasmid DNA indicated plasmid DNA reached the ovules of decapitated florets within about 24 hours after its application to the surface of remaining styles or ovary wound site after pollination. Based on the result of PCR analyses of genomic DNA, 12% to 15% of the plants tested had the 282 bp fragment, the specific portion of the luciferase gene construct into the genome. Southern blotting of genomic DNA from PCR positive plants indicated that the firefly luciferase gene construct may have been incorporated into the genomic DNA of the plants.
