Title: Pliable air duct with dust and condensation repellency
Inventor: GEBKE KEVIN
IPC: F16L9/14
Filed: 2002-09-13
Granted: 2009-04-14
Abstract: A fabric air duct (10) with main discharge openings (16) includes additional , much smaller openings (20) that help ventilate the surface of the duct (10). Ventilating the surface of the duct (10) with a slight yet even amount of airflow helps inhibit the accumulation of condensate and dust on the surface of the duct. In some embodiments, the duct includes a pliable sheet consisti ng of a rather porous fabric base material. To achieve an appropriately low lev el of airflow, a plastic coating on the fabric reduces, but does not eliminate the fabric's porosity. A calendering process then reduces the porosity even further. In other embodiments, the pliable sheet is substantially air impermeable, except for its main discharge openings. The sheet is then perforated with numerous smaller openings to achieve the desired amount of surface ventilation.

Abstract: Solid materials have been developed to remove contaminating metals and organic compounds from aqueous media. The contaminants are removed by passing the aqueous phase through the solid materials which can be in molded, granular, or powder form. The solid materials adsorb the metals and the organics leaving a purified aqueous stream. The materials are sol-gel and or sol-gel and granulated activated carbon (GAC) mixtures. The species-specific adsorption occurs through specific chemical modifications of the solids tailored towards the contaminant(s). The contaminated solid materials can then be disposed of or the contaminant can be removed and the solids recycled.

Title: Surgical stapling instrument having a spent cartridge lockout
Inventor: SHELTON FREDERICK E IV
IPC: A61B17/068
Filed: 2004-05-20
Granted: 2012-02-21
Abstract: A surgical instrument for laparoscopic and endoscopic clinical procedures simultaneously severs and staples tissue clamped in an end effector comprising an elongate channel, which holds a staple cartridge, and a pivotally attached anvil. An E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular, a wedge integral to the staple cartridge is driven distally by a middle pin of the firing bar to effect stapling. A lockout mechanism of the staple cartridge responds to the presence of the wedge sled in its unfired position to allow the firing bar to fire. Otherwise, the lockout mechanism prevents firing when the staple cartridge is spent.

Granted: 2012-03-13
Abstract: In a method, computer program and system for determining an operational limit of a power transmission line, time-stamped current phasor information and voltage phasor information for a first end and a second end of the line are determined, an ohmic resistance of the line is computed from the phasor information, and an average line temperature is computed from the ohmic resistance. This allows to determine the average line temperature without dedicated temperature sensors. The average line temperature represents the actual average temperature and is largely independent of assumptions regarding line parameters.

Abstract: A system, method and database design is provided for unifying data from a plurality of heterogeneous databases (130), each having business-context related data and a data access mechanism (910). A database is created (e.g., the UniDimNet) (210) which contains a node for each dimension of an industry.  For each data source (130) which is accessible via the system, a set of data source specific dimensions (390) is created and mapped to the corresponding industry business context dimension(s). A set of templates (e.g., UniViews) (220) is created to query the data sources (130). Each UniView (220) contains a specific question for a specific dimension designed for a specific data source (172). UniViews query (900) the database they are associated with by using the data access mechanism (910) of the associated database. A central server(120) coordinates the system and facilitates use of the system through an interface (e.g., the UniViewer) (150). The UniViewer (150) allows a user to query the data sources by identifying an industry business context dimension, a dimension instance and at least one UniView (220). Multiple UniViews (220) can be combined, cached and saved to facilitate complex queries.

Title: Wireless communications network and method for enabling wireless presence-based services
Inventor: SAYEEDI SHAHAB M
IPC: H04W4/00
Filed: 2004-05-28
Granted: 2011-03-29
Abstract: The need to enable wireless presence-based services more efficiently is addressed by embodiments of the present invention. A wireless presence proxy (WPP 415) monitors the messaging and messaging responses of a mobile station (MS 401) via wireless transceiver equipment (411). Such messaging and messaging responses do not explicitly specify a presence state or state change for the MS. Thus, based upon this monitoring, the WPP infers the presence state / change for the MS and maintains MS location information. The WPP  communicates any presence state changes and confirms MS presence state as required by the presence server(s) (225). By monitoring messaging, notifying the server(s) of MS presence, and handling server requests (potentially from many servers for the same MS), embodiments of the present invention reduce or avoid many existing inefficiencies, such as wide area paging and call set up and tear down for each presence ping, from each presence server.
