Patents by Inventor James Robert Onstott

James Robert Onstott has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Temperature range adjusted coated optical fibers
    Patent number: 6643440
    Abstract: A coated optical fiber adjusted to operate at a predetermined temperature range. The coated fiber includes an optical fiber, a first polymer coating generally concentrically surrounding the optical fiber and a second polymer coating generally concentrically surrounding the first polymer coating, wherein the first polymer coating includes substantially no coefficient of thermal expansion stresses when the optical fiber is placed at a lower end of the temperature range.
    Type: Grant
    Filed: September 20, 2002
    Date of Patent: November 4, 2003
    Assignee: 3M Innovative Properties Company

  • Method of manufacturing temperature range adjusted coated optical fibers
    Patent number: 6630209
    Abstract: A method for manufacturing a coated optical fiber including the step of determining a desired temperature operating range of a coated optical fiber having at least one critical limit. The intercoating delamination stresses at the critical limit of said temperature range are determined. A zero-stress temperature region using the critical limit and the delamination stresses is then selected. An optical fiber is provided and the optical fiber is coated with a first polymer coating. The first polymer coating is exposed to a source of actinic radiation, wherein the source of actinic radiation generates heat. A second polymer coating including a photopolymerizable composition is applied to the optical fiber directly on the first polymer coating. The second polymer coating is cured, where at the time the second polymer coating is cured the first polymer coating is at the zero-stress temperature region.
