The device is formed of a seamless expanse of thin-film (i) formed of a sputtered nitinol shape memory alloy, defining, in an austenitic state, an open, interior volume, having a thickness between 0 5... | 07/19/2011 |
| 7842143 | Hyperelastic shape setting devices and fabrication methods Shape-setting methods for fabricating devices made of single crystal shape memory alloys. The method include drawing a single crystal of a shape memory alloy from a melt of the alloy. This is followed by heating and quenching the crystal sufficiently rapid to limit ... | 11/30/2010 |
| 7763342 | Tear-resistant thin film methods of fabrication A thin film device and fabrication method providing optimum tear resistance. A thin film layer is formed with a first and second of rows of holes. The holes in each row are spaced-apart along an axis which extends along an edge of the layer. The holes in one row are... | 07/27/2010 |
| 7632361 | Single crystal shape memory alloy devices and methods Devices and methods of making devices having one or more components made of single crystal shape memory alloy capable of large recoverable distortions, defined herein as “hyperelastic” SMA. Recoverable Strains are as large as 9 percent, and in special circumstan... | 12/15/2009 |
| 7586828 | Magnetic data storage system A magnetic data storage system having a scanning tip array based system and a shape memory thin film-based data storage medium. Prior to storing data, the medium is in its non-ferromagnetic austenitic phase. Indentation stress locally induces martensitic transformat... | 09/08/2009 |
| 7544257 | Single crystal shape memory alloy devices and methods Devices and methods of making devices having one or more components made of single crystal shape memory alloy capable of large recoverable distortions, defined herein as “hyperelastic” SMA. Recoverable Strains are as large as 9 percent, and in special circumstan... | 06/09/2009 |
| 7540899 | Shape memory alloy thin film, method of fabrication, and articles of manufacture A method of forming a single crystal in a thin film by progressively rapidly heating (and cooling) a narrow band of amorphous material. The amorphous thin film may be of shape memory alloy such as TiNi or CuAlNi. Heating may be accomplished by a line-focused laser b... | 06/02/2009 |
| 7441888 | Eyeglass frame Eyeglass frame hinges are replaced by flexures made of hyperelastic single-crystal shape memory alloy. These flexures exhibit more than 8 percent recoverable strain. Eyeglass frames with these flexures can be distorted repeatedly in ways that would destroy ordinary ... | 10/28/2008 |
| 7422403 | Non-explosive releasable coupling device A device and method for holding or clamping components together, and with the clamping being selectively loosened to permit the components to move through a predetermined distance without being fully released. A bolt has its head end attached to one component and it... | 09/09/2008 |
| 7084726 | Thin film shape memory alloy actuated microrelay A microrelay device formed on a silicon substrate wafer for use in opening and closing a current path in a circuit. A pair of electrically conducting latching beams are attached at their proximal ends to terminals on the substrate. Proximal ends of the beams have co... | 08/01/2006 |
