20110097581 | IN-FIBER FILAMENT PRODUCTION - In a fiber there is provided a fiber matrix material having a fiber length; and an array of isolated in-fiber filaments that extend the fiber length. The in-fiber filaments are disposed at a radius in a cross section of the fiber that is a location of a continuous filament material layer in a drawing preform of the fiber. As a result, there is provided a fiber matrix material having a fiber length; and a plurality of isolated fiber elements that are disposed in the fiber matrix, extending the fiber length, where the plurality is of a number greater than a number of isolated domains in a drawing preform of the fiber. | 04-28-2011 |

20100316088 | Thermal Sensing Fiber Devices - There is provided a thermal sensing fiber grid, including a plurality of rows and columns of thermal sensing fibers, each of which includes a semiconducting element that has a fiber length and that is characterized by a bandgap energy corresponding to a selected operational temperature range of the fiber in which there can be produced a change in thermally-excited electronic charge carrier population in the semiconducting element in response to a temperature change in the selected temperature range. There is included at least one pair of conducting electrodes in contact with the semiconducting element along the fiber length, and an insulator along the fiber length. An electronic circuit is provided for and connected to each thermal sensing fiber for producing an indication of thermal sensing fiber grid coordinates of a change in ambient temperature. | 12-16-2010 |

20130202888 | In-Fiber Particle Generation - A fiber is provided, including a cladding material that is disposed along a longitudinal-axis fiber length. A plurality of spherical particles are disposed as a sequence along a longitudinal line parallel to the longitudinal fiber axis in at least a portion of the fiber length, and include a spherical particle material that is interior to the fiber cladding material and different than the fiber cladding material. To produce particles, a drawn fiber, having a longitudinal-axis fiber length and including at least one fiber core that has a longitudinal core axis parallel to the longitudinal fiber axis and that is internally disposed to at least one outer fiber cladding layer along the fiber length, is heated for a time that is sufficient to cause a fiber core to break-up into droplets sequentially disposed along the fiber core axis. Fiber cooling solidifies droplets into spherical particles interior to fiber cladding. | 08-08-2013 |
20150044463 | Dynamic In-Fiber Particle Production With Precise Dimensional Control - A fiber is provided that has been thermally drawn from a fiber preform, having a longitudinal-axis length and including at least one core that has a longitudinal core axis parallel to the longitudinal axis and internally disposed to at least one outer fiber cladding material layer along the fiber length. The fiber is fed through a localized heating site having a heating site temperature, T, that is above a melting temperature of the fiber core, with a feed speed, υ | 02-12-2015 |
