| 20120006246 | VARIABLE STIFFNESS TOW CABLE - A variable stiffness tow cable comprising a plurality of strands. Most of the strands comprise a polymer with interstitial spaces filled with a ferrofluid comprising nanoparticles. And, least one of the strands is a nanoparticle control field source. The stiffness is varied for a number of control objectives such to dampen motion. In another application, strum is controlled by electrical input rather than by changing the length of tow cable let out. | 01-12-2012 |
| 20100212712 | THERMOELECTRIC GENERATOR - A thermoelectric generator has a hot side heat exchanger comprising: a silicon carbide (SiC) honeycomb support with a plurality of passages. The passage walls are coated with a pyrophoric solid fuel such as red oxide (Fe | 08-26-2010 |
| 20100154696 | Structural Support to Underwater Vessels Using Shape Memory Alloys - A supporting arrangement for a vessel for counteracting compressive loads at an operating temperature. The supporting arrangement also provides inertial stiffening of the hull of the vessel as well as acoustic and vibration damping. The supporting arrangement includes a support structure that is made from a shape memory alloy that contacts and presses against the inner walls of the vessel. The supporting arrangement utilizes the shape recovery properties and/or the internal energy properties of the shape memory alloy support structure to provide reinforcing and damping forces. | 06-24-2010 |
