| 20090096440 | Methods and Systems for Measurement of Fluid Electrical Stability - The invention relates particularly to methods and apparatuses for characterizing water-in-oil or invert emulsion fluids for use in drilling well bores in hydro-carbon bearing subterranean formations. A fluid stability measurement device is disclosed. The device comprises a reference electrode and a second electrode coupled to an insulating body. A guard electrode is placed in the path between the reference electrode and the second electrode on the surface of the insulating body. | 04-16-2009 |
| 20090163388 | Variable Density Treatment Fluids - The present invention provides variable density fluid compositions and methods for using such compositions in a subterranean formation. One exemplary embodiment of the variable density fluid compositions of the present invention comprises a variable density fluid comprising: a base fluid, and a portion of variable pressure weighting material particles. | 06-25-2009 |
| 20110011788 | Pressure Vessels with Safety Closures and Associated Methods and Systems - A pressure vessel having a cell with a locking pin, and a cap and associated methods and systems. The locking pin may be configured to engage the cap when the pressure vessel is pressurized to prevent rotation of the cap without depression of the cap. | 01-20-2011 |

| 20090217776 | Real-Time Filtration Apparatus and Associated Methods - A fluid testing apparatus and associated method include a testing chamber, a filter storage device and a filter transfer mechanism. The testing chamber has a sample volume, a filtrate collection reservoir, an opening between the sample volume and the filtrate collection reservoir, and at least one port into the sample volume. The filter transfer mechanism positions at least one filter in the opening. The opening is closed and a sample fluid, introduced into the port, at least partially fills the sample volume. The sample volume is pressurized and a filtrate of the sample fluid flows from the sample volume, through the filter into the filtrate collection reservoir. The volume of filtrate passing into the filtrate collection reservoir is measured and the sample fluid from sample volume is discharged. The filtrate is discharged from the filtrate collection reservoir, and the filter transfer mechanism removes the filter. | 09-03-2009 |
| 20100139387 | Methods and Systems for Characterizing LCM Particle Plugging and Rheology in Real Time - Methods and systems for characterizing drilling fluids laden with LCM (Lost Circulation Material) and other solid materials are disclosed. A test cell for analyzing a fluid is provided with a first conical inner portion and an axial positioning device positioned along an axis of the test cell. A first conical plug is coupled to the axial positioning device and is movable in and out of the first conical inner portion along the axis of the test cell. A fluid inlet is positioned at a first location on the test cell and a fluid outlet at a second location. | 06-10-2010 |

| 20080216699 | Non-lethal projectile for disorienting adversaries - Projectile apparatus is provided employing light and sound that may be dispersed over a large area with high intensity to produce a non-lethal, visible and audible countermeasure to temporarily blind and/or disorient one or multiple potential adversaries. The apparatus is suitable for use in tactical scenarios by military, police, and special operations personnel. The apparatus is also suitable for use in training operations for military, police, and special operations personnel. For amusement or recreation, the apparatus may be used in simulated warfare or in games such as paintball. | 09-11-2008 |
| 20100204910 | Navigational Display for Parachutists - A display system for a parachutist is provided based on navigation data and calculations of locations where the parachutist should steer the parachute to increase likelihood of reaching a target. A two-dimensional representation of a navigation funnel is displayed. The display may increase situational awareness by use of color to indicate preferred positions in the navigation funnel. | 08-12-2010 |

| 20100026343 | CLOCKED SINGLE POWER SUPPLY LEVEL SHIFTER - First circuitry is powered by a first power supply domain and provides a data signal referenced to the first power supply domain. Second circuitry is powered by a second power supply domain that differs from the first power supply domain. The data signal becomes referenced to the second power supply domain by a clocked level shifter that couples the first circuitry to the second circuitry and buffers the data signal from the first power supply domain to the second power supply domain by only using a single supply voltage. The clocked level shifter is clocked by a signal that is used to precharge a first node and a second node of the clocked level shifter until the data signal is valid for at least a setup time period. The first and second nodes are precharged to establish a known state in the clocked level shifter. | 02-04-2010 |
