| 20120065721 | THERMOPLASTIC FLUOROPOLYMER-COATED MEDICAL DEVICES - A medical device provided with at least a partial surface coating of a thermoplastic copolymer of tetrafluoroethylene and perfluoroalkylvinylether that is free of cross-linking monomers and curing agents. The fluoropolymer coating is preferably an amorphous thermoplastic, is highly inert and biocompatible, has elastomeric characteristics that provide desirable mechanical properties such as good flexibility and durability. These characteristics allow the coating to be considered “functionally transparent” because it withstands mechanical deformations required for the assembly, deployment, expansion, and placement of medical devices, without any adverse effect on the mechanical and biological functionality of the coated device. Further, its inertness, derived from the perfluorocarbon structure, contributes to its functionally transparent nature. The coating can be provided with various liquid or solid additives, can be loaded with large quantities of additives including a wide range of therapeutic agents, and has excellent drug elution characteristics when elutable additives are used. | 03-15-2012 |

| 20100056357 | Ready-to-sinter spinel nanomixture and method for preparing same - An in-situ method for nanomixing magnesium aluminate spinel nanoparticles with a uniformly distributed controlled concentration of nanoparticles of an inorganic sintering aid, such as LiF, to produce ready-to-sinter spinel powder. The spinel-sintering aid nanomixture is formed by induced precipitation of the sintering aid nanoparticles from a dispersion of the spinel nanoparticles in an aqueous solution of the sintering aid, followed by separation, drying and deagglomeration of the spinel-sintering aid nanomixed product. | 03-04-2010 |
| 20100144510 | Production of sintered three-dimensional ceramic bodies - A freeze-forging method for producing sintered three-dimensional ceramic bodies, particularly magnesium aluminate spinel domes. The method comprises forming a ceramic mix of a ready-to-sinter ceramic powder and a nonaqueous liquefied sublimable vehicle having a solidification temperature from room temperature to below 200° C.; reducing the temperature of the ceramic mix to below the vehicle's solidification temperature to freeze the mix; crushing the frozen mix into powdered form; cold forging the frozen powder in a mold to form a solidified green body of the desired three-dimensional shape; and densifying the green body into a sintered three-dimensional ceramic body. | 06-10-2010 |

| 20080294906 | Retrieval and Display of Encryption Labels From an Encryption Key Manager Certificate ID Attached to Key Certificate - A method, system and program in which a certificate identifier (ID) is associated with an encryption certificate. In certain embodiments, the certificate ID is stored in a cartridge memory (CM). Thus, keystore or key manager administrators can trace keystore locations, versions of keystores, etc. when a cart cannot locate a correct key. This certificate ID, as it is stored on the cartridge memory, is viewable by all. | 11-27-2008 |
| 20090003609 | Method for Updating Encryption Keystores Within a Data Processing System - A method for updating encryption keystores within a computer network having multiple host computers is disclosed. A keystore is initially loaded into a key manager within one of the host computers. In response to a key request by a peripheral device within the computer network, a determination is made whether or not the keystore is currently being updated. In a determination that the keystore is not currently being updated, the loaded keystore is utilized to handle the key request. In a determination that the keystore is currently being updated, any incoming key request is redirected to a local queue associated with the key manager. Afterwards, the updated keystore is utilized to handle the key request and any other key request pending in the local queue associated with the key manager. | 01-01-2009 |
| 20090006322 | Method for Handling Web Search Results to Be Displayed on a Browser - A method for handling web search results to be displayed on a browser is disclosed. A history information file is initially provided on a search server connected to a network. The history information file includes a set of previously viewed websites. After the receipt of a search request from an internet browser on a computer connected to the network, an internet search is preformed according to a search criteria of the search request. After the previously viewed websites listed on the history information file have been removed from the current internet search results, the current search results are then sent to the internet browser to be displayed on the internet browser. | 01-01-2009 |

| 20080219453 | MAINTAINING KEYS REMOVED FROM A KEYSTORE IN AN INACTIVE KEY REPOSITORY - Provided are a method, system, and article of manufacture for maintaining keys removed from a keystore in an inactive key repository. A keystore includes active keys, wherein at least one active key in the keystore is associated with at least one storage device and available for encrypting and decrypting data with respect to the associated storage device. A request is received for an operation with respect to a specified active key that causes the specified active key to be removed as an active key from the keystore. The specified active key is indicated as inactive, wherein keys indicated as inactive are not available for use to encrypt and decrypt data. A request is received to restore one of the inactive keys to make available to decrypt and encrypt data for the at least one associated storage device associated with the requested inactive key. The requested inactive key to restore is indicated as active in the keystore, wherein the restored key and any other active key in the keystore associated with the at least one storage device with which the restored key is associated are available to be provided to use to encrypt and decrypt data with respect to the at least one storage device with which they are associated. | 09-11-2008 |
