20090055445ON DEMAND DATA CONVERSION - Novel tools for updating data structures in a database. In an aspect, the tools are used to update a database's structures in response to the update of an application (such as an enterprise application) that uses the database. In another aspect, the tools may convert a data set to a new format when the updated application attempts to access the data set; in some cases, other data sets within the database might remain unconverted until their use. Advantageously, this allows for a database (and/or a table within a database) to be updated incrementally and/or on demand. This feature can mitigate the impact of the update on users, for example, by avoiding the need to take the database (and/or application) offline to perform a batch process to update the database.02-26-2009

20080295588FORMATION TESTER TOOL SEAL PAD - A formation tester tool includes a formation tester tool body having a surface, a formation probe assembly located within the formation tester tool body, the formation probe assembly including a piston reciprocal between a retracted position and an extended position beyond the surface of the formation tester tool body, the piston being slidingly retained within a chamber, and a seal pad located at an end of the piston, wherein the seal pad includes a first inner sealing element and a second outer sealing element.12-04-2008
20090183882PACKER VARIABLE VOLUME EXCLUDER AND SAMPLING METHOD THEREFOR - A down hole apparatus includes a first expandable packer and a second expandable packer, where the first expandable packer longitudinally spaced from the second expandable packer. The apparatus further includes an optional expandable bladder disposed at a longitudinal location between the first expandable packer and the second expandable packer. The expandable bladder inflates to displace drilling fluid between the first and second bladder elements. The down hole apparatus can optionally displace drilling fluid between the first and second bladder elements with another fluid. Fluids and/or slurry can be selectively removed using ports between the first and second expandable packers, and optionally placed in sample chambers, or expelled to the bore hole.07-23-2009
20100089569SEPARATOR FOR DOWNHOLE MEASURING AND METHOD THEREFOR - A separator for downhole measuring during sampling in a subterranean formation. The separator allows for mixed fluid phases to be separated while flowing formation fluid therethrough.04-15-2010
20100132940FOCUSED PROBE APPARATUS AND METHOD THEREFOR - Apparatus and methods for downhole formation testing including use of a probe having inner and outer channels adapted to collect or inject injecting fluids from or to a formation accessed by a borehole. The probe straddles one or more layers in laminated or fractured formations and uses the inner channels to collect fluid.06-03-2010
20100132941APPARATUS AND METHOD FOR MANIPULATING FLUID DURING DRILLING OR PUMPING OPERATIONS - A method and apparatus for manipulating fluid, such as measuring bubble point, during drilling or pumping operations including pumping fluid in a borehole through a flow line (06-03-2010
20110048700APPARATUS AND METHOD FOR FLUID PROPERTY MEASUREMENTS - In some embodiments, apparatus and systems, as well as methods, may operate to measure formation fluid and obtain data, the data having measurement levels that vary over a parameter. The data is grouped in one or more categories, each category having data falling within a range, and the grouped data is analyzed as a function of the parameter. In some embodiments, the grouped data is used to identify at least one fluid type of the formation fluid using the grouped data.03-03-2011

20100078873SINGULATING SHEET FEEDER - A singulating sheet feeder includes a deck for slidably supporting a plurality of sheets and a drive system for moving the sheets along the deck. The drive system includes a drive element for engaging a lowermost sheet to move the sheets into a shingled arrangement. The sheet feeder further includes a transport element for transporting the lowermost sheet away from the plurality of sheets and a separator element proximate to the transport element including a substantially planar surface for engaging leading edges of subsequent sheets to retard motion of the subsequent sheets as the lowermost sheet is transported, wherein the substantially planar surface is disposed at an acute angle to the deck.04-01-2010
