Publication number: 20150366107Abstract: A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive core layer of metallic foam having generally parallel opposed surfaces and a face sheet having rigidity properties superior to the rigidity properties of the core layer laminated to a surface of the core layer. Alternatively, a panel for a broadband electromagnetic shield includes a composite fiber-reinforced core having opposed surfaces and a layered electrically-conductive composite cover disposed on a surface of the core. The cover includes a first stratum of porous metal exhibiting pronounced low-frequency electromagnetic shielding properties and a second stratum of electrically-conductive elements exhibiting pronounced high-frequency electromagnetic shielding properties secured in an overlapping electrically-continuous relationship to the first stratum, the first stratum being a metallic lattice, and the electrically-conductive elements being a non-woven veil of electrically-nonconductive metal-coated fibers.Type: ApplicationFiled: August 21, 2015Publication date: December 17, 2015Applicant: Conductive Composites Company, LLCInventors: George Clayton Hansen, Nathan D.

Patent number: 9198675Abstract: A surgical rasping and/or shaving system functions in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping and/or shaving head which may be low profile and offer a flat cutting/rasping/shaving surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the system to provide ablation or coagulation of soft tissues.Type: GrantFiled: April 18, 2013Date of Patent: December 1, 2015Assignees: IMDS LLCInventors: Keith J. Nelson, Daniel F. Justin, Douglas M. Lorang, Andrew R. Fauth, Daniel J. Triplett, Trevor K. Lewis, Gavin Sontag, Nathan D. Hansen, Karen E. Mohr, Joseph Q. Marietta, M. Mary Sinnott

Patent number: 9167733Abstract: A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive, fluid-permeable planar core layer defined between generally parallel first and second surfaces and a first face sheet laminated to the first surface of the core layer with rigidity properties superior to the rigidity properties of the core layer. The thickness of the first face sheet is substantially less than the thickness of the core layer. The core layer is made of metallic foam or a metal coating on an electrically-nonconductive, porous, nonmetallic substrate chosen from among nonwoven fibrous matting, paper, and open-cell nonmetallic foam. Also, the core layer may also may be made up of liberated branching metal nanostrands or a plurality of electrically-coupled, electrically-conductive particles, each taking the from of an electrically-nonconductive, nonmetallic substrate with a metal coating.Type: GrantFiled: April 5, 2013Date of Patent: October 20, 2015Assignee: Conductive Composites CompanyInventors: George Clayton Hansen, Nathan D.

Patent number: 8963022Abstract: A panel for an electromagnetic shield includes a light-weight, porous, electrically-conductive, fluid-permeable planar core layer defined between generally parallel first and second surfaces and a first face sheet laminated to the first surface of the core layer with rigidity properties superior to the rigidity properties of the core layer. The thickness of the first face sheet is substantially less than the thickness of the core layer. The core layer is made of metallic foam or a metal coating on an electrically-nonconductive, porous, nonmetallic substrate chosen from among nonwoven fibrous matting, paper, and open-cell nonmetallic foam.

Publication number: 20140091982Abstract: A highly conductive fiber reinforced tubular antenna is composed of metal coated reinforcing fibers in a composite structure. The conductive fibers may be disposed in a tubular or cylindrical fashion unidirectionally parallel to or at an angle to the axis of the tube or cylinder, thus providing multifunctional properties of strength and conductivity. Alternatively, the conductive fibers may be non-woven in configuration and disposed on one or more wrapped layers to form the antenna. The fiber reinforced composites disclosed are both lighter and stronger than their metal counterparts, while the highly increased conductive surface area in the composite creates enhanced electrical or electromagnetic performance than tubular or cylindrical antennas made of metal or nonmetal composite structures.Type: ApplicationFiled: September 24, 2013Publication date: April 3, 2014Inventors: George C. Hansen, Nathan D. Hansen, Jon S. Bial, Gary Loomis

Publication number: 20140094331Abstract: Weighted arrow shafts and other athletic equipment composed of hollow shafts are constructed from carbon/graphite fibers. Such carbon/graphite fiber material may be at least in part coated with nickel or other metal or alloy to alter the weight of the carbon/graphite fiber material and, thus, the weight or weight distribution of the athletic equipment along the length of the hollow shaft.Type: ApplicationFiled: September 24, 2013Publication date: April 3, 2014Inventors: George C.

Publication number: 20130134364Abstract: An electromagnetically active composite has an electrically-nonconductive host matrix and electrically-conductive nanostrand bodies embedded in a substantially uniform distribution throughout the host matrix. Each of the nanostrand bodies comprises a volume containing at least one nanostrand of filamentary metal. Adjacent nanostrand bodies that are sufficiently mutually proximate will interact electromagnetically with each other. The filamentary metal of the one or more nanostrands in each of the nanostrand bodies occupies a deminimus fraction of the overall volume occupied by the at least one nanostrand that comprises each of the nanostrand bodies. The filamentary metal is chosen from among the group of metals that includes nickel, nickel aluminides, iron, iron aluminides, alloys of nickel and iron, and alloys of nickel and copper.Type: ApplicationFiled: January 23, 2013Publication date: May 30, 2013Applicant: Conductive Composites Company, LLCInventors: George Clayton Hansen, Nathan D.
