| 20090216910 | COMPUTING INFRASTRUCTURE - An affordable, highly trustworthy, survivable and available, operationally efficient distributed supercomputing infrastructure for processing, sharing and protecting both structured and unstructured information. A primary objective of the SHADOWS infrastructure is to establish a highly survivable, essentially maintenance-free shared platform for extremely high-performance computing (i.e., supercomputing)—with “high performance” defined both in terms of total throughput, but also in terms of very low-latency (although not every problem or customer necessarily requires very low latency)—while achieving unprecedented levels of affordability at its simplest, the idea is to use distributed “teams” of nodes in a self-healing network as the basis for managing and coordinating both the work to be accomplished and the resources available to do the work. The SHADOWS concept of “teams” is responsible for its ability to “self-heal” and “adapt” its distributed resources in an “organic” manner. Furthermore, the “teams” themselves are at the heart of decision-making, processing, and storage in the SHADOWS infrastructure. Everything that's important is handled under the auspices and stewardship of a team. | 08-27-2009 |

The method is designed for a wide variety of digital processing platforms, including highly parallel machines. The method may also be adapted to the analysis of (semi-structured) flows in other contexts including water systems and electrical grids. | 08-27-2009 |

| 20100040748 | PROCESS FOR AQUEOUS OIL EXTRACTION FROM OILSEED STARTING MATERIAL - A process is disclosed for the efficient recovery of oil from oilseed materials without the use of organic solvents. In the process, the oilseed starting material is first expelled to remove a portion of the total oil. The expelled cake retains the remainder of the oil from the starting seed. This cake is slurried in water and the pH of the slurry is adjusted to pH >8 with an alkaline compound. This pH adjustment results in release of oil from binding to other compounds and structures in the slurry. The slurry is then processed through a solids-liquid separation to produce a protein-enriched solids phase and an oil-in-water liquid phase. The liquid phase is then further processed to separate the oil from the water and recover the oil as free oil. The recovered oil can then be added to the expelled oil. | 02-18-2010 |

| 20100195441 | PARALLEL-PATH ACOUSTIC TELEMETRY ISOLATION SYSTEM AND METHOD - An acoustic telemetry isolation system and method for use with tubular assemblies such as drillpipe and production tubing includes an acoustic wave transmitter and an acoustic isolator.

Furthermore, the acoustic isolator is similarly effective in reflecting “up” propagating waves originating from below the isolator, hence further protecting the acoustic wave source from possible deleterious interference. The construction of the isolator utilizes a specified combination of waves traveling in parallel in materials whose properties aid the beneficial combination of reflected and transmitted waves. The design of the isolator is to generally provide a bandstop filter function, thereby aiding the frequency isolation of an acoustic transmitter over a passband that may be constrained by the geometry of drill pipe or components of production tubing.
