Abstract: Systems and methods for coupling subsea tubular members together are provided. An apparatus may be used to properly orient and/or provide communication between a first subsea tubular member that is being landed on a second subsea tubular member. An apparatus for coupling subsea tubular members may include an alignment sub and a corresponding alignment member. The alignment sub includes: a generally cylindrical body having one or more fluid, electric, or fiber optic lines extending therethrough, one or more couplings coupled to at least one end of the alignment sub, and an orientation profile disposed on a surface of the alignment sub. The alignment member has a profile designed to interface with the orientation profile of the alignment sub. One of the alignment sub and the alignment member remains stationary while the other rotates relative to the stationary structure.

Abstract: Systems and methods for landing a tubing hanger in a wellhead and then orienting a tree (or spool, or flowline connection body) relative to the tubing hanger while landing the tree on the wellhead are provided. This alignment is accomplished without the use of either a tubing spool or a BOP stack with an orientation pin. The tubing hanger alignment devices may be used to orientate the tree as the tree is landed so that the couplings and stabs between the tree and the tubing hanger line up with each other just at the moment of landing.

Abstract: A method for producing an arc quenching fuse filler including providing a conventional fuse filler material, mixing a binder agent with the conventional fuse filler material, mixing an arc quenching promotor with the conventional fuse filler material and binder agent, and curing the binder agent, whereby granules of the arc quenching promotor are bound to granules of the conventional fuse filler material.

Abstract: The invention provides a method for capturing, tracking and managing a transaction of a user at an advanced Point-of-Sale (POS) register. The method steps include obtaining transaction data of the transaction from the POS register using a mobile device and managing POS-based expenditures of the user using the transaction data including a transaction amount, a payment type of the transaction, and relevant bank or credit card account information for the method of payment used by the user. Managing POS-based expenditures may include generating a real-time balance of the account based on the transaction data and presenting the real-time balance of the account to the mobile device.

Abstract: A system for collecting information is described. During operation, this system aggregates information from multiple information sources based on user preferences. Then, the system requests additional information from a user about ambiguities or variations in the aggregated information. These ambiguities are associated with changes in user activities, and the changes may be determined using a user-activity history and/or user preferences. Note that the system can repeat the aggregating and requesting operations multiple times.
