| 20110083861 | WELL TOOL INCLUDING SWELLABLE MATERIAL AND INTEGRATED FLUID FOR INITIATING SWELLING - A well tool including swellable material and integrated fluid for initiating swelling. A well tool includes a swellable material and a reservoir for containing a fluid of a type which causes the swellable material to swell. A method of swelling a swellable material included in a well tool includes the steps of: positioning the well tool in a well; and then activating a fluid to cause swelling of the swellable material. A method of swelling a swellable material includes the steps of: providing the swellable material which is capable of swelling when contacted by a fluid; positioning the swellable material in an environment in which the swellable material is contacted by another fluid which does not cause the material to swell; and swelling the swellable material by contacting the swellable material with the first fluid while the swellable material remains in contact with the other fluid. | 04-14-2011 |

| 20090065195 | Passive Completion Optimization With Fluid Loss Control - Passive completion optimization with fluid loss control. A completion string includes a set of well tools interconnected as a portion of the completion string, the well tools including a well screen assembly, at least one valve which controls fluid communication between an interior and exterior of the string, and two packer assemblies, each of the packer assemblies including at least one swellable seal element, and the packer assemblies longitudinally straddling the valve and the screen assembly. Another completion string includes a set of well tools interconnected as a portion of the completion string, the well tools including two packer assemblies, a well screen assembly, and the screen assembly including an inflow control device which restricts fluid flow through the screen assembly, each of the packer assemblies including a swellable seal element, and the packer assemblies longitudinally straddling the screen assembly. | 03-12-2009 |

| 20120067565 | SWELLABLE PACKER WITH ENHANCED SEALING CAPABILITY - A swellable packer with enhanced sealing capability. A packer assembly includes multiple seal elements, each seal element being swellable downhole, each seal element having at least one face inclined relative to a longitudinal axis of the assembly, and the inclined faces of adjacent seal elements contacting each other. A method of constructing a packer assembly having a desired differential pressure sealing capability includes: providing a base pipe and multiple seal elements, each seal element being swellable in a downhole environment, and each seal element having a predetermined differential pressure sealing capability less than the desired sealing capability; and after the desired sealing capability is determined, installing a selected number of the seal elements on the base pipe, so that the combined predetermined differential pressure sealing capabilities of the installed seal elements is at least as great as the desired sealing capability. | 03-22-2012 |

| 20110257812 | VEHICLE TRACKING SYSTEM - One or more tracked vehicles with wireless broadband connectivity to a central tracking station provide redundant location data derived from an onboard GPS receiver and an onboard self-triangulating cell phone. Tracking data for bar-coded and RFID-tagged items with the vehicle are also tracked. Clandestine audio monitoring of the vehicle interior and exterior can be enabled from the tracking station or from a remote access device. Redundant rollover sensing and reporting is provided by a roll over switch and a cell phone loss of signal. Hardwired and proximity vehicle panic alarms communicate with the central tracking station. A remote engine kill is provided. A tracking server within the tracking station stores data and generates reports and alarms. HF radio and cell phone communication between the tracking station and the vehicle are also enabled. | 10-20-2011 |

| 20110144304 | Chemical Modification of Proteins - The invention relates to methods for selectively converting a cysteine residue in a peptide or protein to the dehydroalanine (Dha) residue. The method also works on selenocysteine and substituted cysteine and selenocysteine residues, resulting in the Dha residue which may be converted to any natural or unnatural amino acid residue desired without the alteration of the remainder of the peptide or protein. The invention also allows ligation of a desired peptide at any point rather than at a point where there should be a naturally occurring cysteine, thereby allowing native chemical ligation to be used in the synthesis of peptides that do not contain cysteine. The methodology allows for the synthesis of very large peptides. | 06-16-2011 |

| 20110067346 | PREFABRITCATED FRAMING MEMBER SUPPORT SYSTEM AND METHODS FOR INSTALLING A PREFABRICATED FRAMING MEMBER SUPPORT SYSTEM IN A CONSTRUCTION APPLICATION - The disclosure relates to a prefabricated framing member support system and methods for installing such a system with a horizontal framing member, the horizontal framing member having a top chord, a bottom chord, a web connecting the top chord to the bottom chord and a framing member cross sectional end profile. The prefabricated support system includes an integrated rim board component having a substantially L-shaped cross sectional end profile. The integrated rim board component includes a substantially vertical portion and a substantially horizontal portion. | 03-24-2011 |
