20110011582 | IN SITU COMBUSTION WITH MULTIPLE STAGED PRODUCERS - Methods and apparatus relate to in situ combustion. Configurations of the injection and production wells facilitate the in situ combustion. Utilizing wet combustion for some embodiments promotes heat displacement for hydrocarbon recovery with procedures in which one or more of the production and injection wells are configured with lengths deviated from vertical. In some embodiments for either dry or wet combustion, at least the production wells define intake lengths deviated from vertical and that are disposed at staged levels within a formation. Each of the productions wells during the in situ combustion allow for recovery of hydrocarbons through gravity drainage. Vertical separation between the intake lengths of the production wells enables differentiated and efficient removal of combustion gasses and the hydrocarbons. | 01-20-2011 |

20080270627 | DOCKING PLATFORM FOR DEVELOPING PORTABLE PACKET PROCESSING APPLICATIONS IN A NETWORK PROCESSOR - An apparatus for developing portable packet processing applications on network processors includes a docking platform which provides a common interface for individual packet processing applications to be plugged into the network processing environment. Each application interacts with the docking platform through the common interfaces provided by the latter. The docking platform interacts with the other modules inside the system to accomplish the requests from the application. In this manner, the applications become “shielded” from the implementation details of the underlying hardware. The applications need not change when the network processor hardware features are changed. It therefore provides a universal packet processing programming environment in which applications can execute in a portable and flexible manner in various hardware architectures. | 10-30-2008 |

20120059633 | Methods and Devices for Transformation of Collected Data for Improved Visualization Capability - Rock physics guided migration is disclosed to enhance subsurface three-dimensional geologic formation evaluation. In one embodiment, a geologic interpretation is generated based on a seismic data volume. Sets of compaction and acoustic formation factor curves are generated, and these are combined into a set of velocity-relationship curves. A pore pressure is derived and used to establish a pore pressure state. A rock physics template is then generated utilizing the derived information. This rock physics template can be used to refine geologic formation evaluation with any suitable form of migration technique. | 03-08-2012 |

20090140882 | DYNAMIC SPEED LIMIT SYSTEM - A method, medium and implementing processing system are provided in which the presence of workers in a long highway construction zone is monitored and the electronically-controlled posted speed limit is adjusted in accordance with the detected presence of workers in the immediate area. In an example, Radio Frequency Identification (RFID) scanners or readers are strategically placed in a construction or working area. Such RFID reading devices may be embedded, for example, in construction speed limit signs. The displayed speed limit is controlled by the detected proximity of construction workers wearing RFID-embedded clothing, for example, such as safety vests or helmets. The speed limit sign includes logic to display one of many possible speed limit displays based on the nearest, and/or the number of RFID signals detected in a given area. Vehicular traffic is thereby enabled to travel faster through construction zones where no workers are present and, when appropriate, traffic is slowed when workers are present within a given proximity of the RFID reading devices. | 06-04-2009 |
