| 20080202914 | De-entrainment tray for high capacity operation - A de-entrainment device separates entrained liquid from vapor in a fluid stream that flows through a chimney tray in a distillation tower. The separated liquid is collected and shielded from the fluid stream to prevent re-entrainment of the liquid in the vapor flowing upward into the tower. The chimney tray includes risers with hats that have gutters to guide liquid toward the tray deck, channels to collect and drain liquid from the top of the hats to the tray deck, and baffles extending from the risers to shield the liquid collected on the tray deck from the vapor flow. | 08-28-2008 |
| 20080314729 | Core de-entrainment device for vessels with tangential inlets - A distillation tower for use in a petrochemical or petroleum operation effects liquid and vapor separation by using centrifugal force applied to the feed introduced into a ring from a tangential inlet. The feed is separated into a liquid component that flows into the bottoms section of the tower and a vapor component that flows upwardly through the core of the ring to a wash zone in the tower. De-entrainment devices are provided in the core so that the vapor swirling upwardly impacts the devices and any remaining entrained liquid is separated from the vapor. As a result, overflash with decreased resid can be collected from the wash zone and used as feed suitable for a fluid catalytic cracking operation, for example. | 12-25-2008 |
| 20090101546 | Distillation tower construction and operation - A combination of differently sized structured packings in the wash zone of distillation towers is provides advantages at high vapor rates. The use of a large crimp structured packing below a smaller crimp size structured packing is advantageous for vacuum crude unit service where fouling resistance is desirable and liquid entrainment into the wash zone is a problem at high vapor rates. The tower may be operated at high vapor flux rates or C 0.4 ft/sec or higher (0.12 m/sec). An unexpected characteristic of the combinations is that the entrainment increases only slowly with increasing vapor flux rate up to Cs values of at least 0.55 ft/sec (0.17 m.sec), as compared to other packings such as random packing, grid packing and combinations of grid packing with structured packing which allow entrainment to increase sharply at high vapor rates. | 04-23-2009 |

| 20090049278 | EFFICIENT MEMORY UPDATE PROCESS FOR ON-THE-FLY INSTRUCTION TRANSLATION FOR WELL BEHAVED APPLICATIONS EXECUTING ON A WEAKLY-ORDERED PROCESSOR - A multiprocessor data processing system (MDPS) with a weakly-ordered architecture providing processing logic for substantially eliminating issuing sync instructions after every store instruction of a well-behaved application. Instructions of a well-behaved application are translated and executed by a weakly-ordered processor. The processing logic includes a lock address tracking utility (LATU), which provides an algorithm and a table of lock addresses, within which each lock address is stored when the lock is acquired by the weakly-ordered processor. When a store instruction is encountered in the instruction stream, the LATU compares the target address of the store instruction against the table of lock addresses. If the target address matches one of the lock addresses, indicating that the store instruction is the corresponding unlock instruction (or lock release instruction), a sync instruction is issued ahead of the store operation. The sync causes all values updated by the intermediate store operations to be flushed out to the point of coherency and be visible to all processors. | 02-19-2009 |

If the checksums do not match, the read/write operation fails and the error is logged. If the checksums match, the integrity check is repeated through each layer in the read/write path to enable detecting data corruption at the point of source. | 03-19-2009 |

| 20120086780 | Utilizing Depth Information to Create 3D Tripwires in Video - A method of processing a digital video sequence is provided that includes detecting a foreground object in an image captured by a depth camera, determining three-dimensional (3D) coordinates of the foreground object, and comparing the 3D coordinates to a 3D video tripwire to determine if the foreground object has crossed the 3D video tripwire. A method of defining a 3D video tripwire is also provided. | 04-12-2012 |
| 20120087572 | Use of Three-Dimensional Top-Down Views for Business Analytics - A method of analyzing a depth image in a digital system is provided that includes detecting a foreground object in a depth image, wherein the depth image is a top-down perspective of a scene, and performing data extraction and classification on the foreground object using depth information in the depth image. | 04-12-2012 |
| 20120087573 | Eliminating Clutter in Video Using Depth Information - A method of clutter elimination in digital images is provided that includes identifying a foreground blob in an image, determining a depth of the foreground blob, and indicating that the foreground blob is clutter when the depth indicates that the foreground blob is too close to be an object of interest. Methods for obstruction detection in depth images such as those captured by stereoscopic cameras and structured light cameras are also provided. | 04-12-2012 |
| 20120092458 | Method and Apparatus for Depth-Fill Algorithm for Low-Complexity Stereo Vision - A method and apparatus for depth-fill algorithm for low-complexity stereo vision. The method includes utilizing right and left images of a stereo camera to estimate depth of the scene, wherein the estimated depth relates to each pixel of the image, and updating a depth model with the current depth utilizing the estimated depth of the scene. | 04-19-2012 |
| 20120148093 | Blob Representation in Video Processing - A method of processing a video sequence is provided that includes receiving a frame of the video sequence, identifying a plurality of blobs in the frame, computing at least one interior point of each blob of the plurality of blobs, and using the interior points in further processing of the video sequence. The interior points may be used, for example, in object tracking. | 06-14-2012 |
