Abstract: The described embodiments relate generally to methods to enhance cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by the friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line in with a cosmetic surface portion of friction stir processed parts. In some embodiments cold spray can be used to on its own to create a cosmetic joint between various parts. Structural joints between first and second substrates may also be formed via solid state deposition. Such joints may be strengthened through use of a hidden weld, mechanical interlocking between the substrates, and/or coupling via fasteners.

Abstract: The present invention is directed to methods of making nanofiber yarns. In some embodiments, the nanotube yarns comprise carbon nanotubes. Particularly, such carbon nanotube yarns of the present invention provide unique properties and property combinations such as extreme toughness, resistance to failure at knots, high electrical and thermal conductivities, high absorption of energy that occurs reversibly, up to 13% strain-to-failure compared with the few percent strain-to-failure of other fibers with similar toughness, very high resistance to creep, retention of strength even when heated in air at 450° C. for one hour, and very high radiation and UV resistance, even when irradiated in air.

Abstract: Managing different versions of a data record is provided. A mapping is maintained between a version-independent logical record identifier and a version-dependent physical record row identifier that correspond to each data record within a plurality of data records of a data table using a logical record identifier to physical record row identifier indirection mapping table. Entries within leaf pages of an index associated with the data table are updated to point to the version-independent logical record identifier corresponding to a data record instead of pointing to the version-dependent physical record row identifier corresponding to the data record. The logical record identifier to physical record row identifier indirection mapping table is updated in response to performing an operation on the data record instead of updating the entries within the leaf pages of the index associated with the data table.

Abstract: A game is shown that includes a deck of cards numbered 1 to 100. Also revealed is a method of playing the game by one or more players. All players are dealt 8 cards. One card is exposed. Utilizing two or more cards from the player's hand and the exposed card in a simple mathematical operation makes a play. The object of the game is to rid one's hand of all cards.

Abstract: A computer receives information about ink usage by a printing device over a period of time. The computer calculates a cost-per-unit of ink for the printing device based on a cost of printer sustainment and based on the ink usage information. The computer may output the cost-per-unit of ink on an external device.

Abstract: A system for transmitting encrypted print job data across a network. The printer driver on the client device encrypts the print job data using a random AES key and uses the printer's public key to encrypt the random AES key. The print job data remains encrypted during transmission from the client device to the printer via the server. As such, the contents of the print job cannot be viewed by anyone who eavesdrops on the communications between the client device and the printer or by anyone who obtains the print job data from the server's data storage medium. The printer's public certificate, containing the printer's public key, is promulgated to the client device via the server which stores the printer's public certificate with other data pertinent to the client device's printer driver.
