20100018716 | Adjustable Hanger for Inner Production Riser - A string of conduit extending from a subsea wellhead assembly to a surface wellhead assembly on a platform has a plurality of grooved profiles on an upper portion of the conduit. Each profile is spaced axially from another of the grooved profiles. After a lower end of the conduit is secured to the subsea wellhead assembly, the operator pulls on the conduit to apply a selected tension to the conduit. The operator attaches a support ring to the profile that was closest to and above a load shoulder in the surface wellhead assembly when the desired tension was reached. After landing the support ring on the load shoulder, the operator may cut off any excess portion of the upper portion of the conduit located above the support ring. A seal ring is set between the upper portion of the conduit and the surface wellhead housing. | 01-28-2010 |
20150083943 | Quadruple RAM BOP - A blowout preventer having a body, a main bore in the body, and rams that project into the main bore. The rams can be shear rams for shearing a tubular in the main bore, pipe rains for sealing around a tubular in the main bore, or sealing rams that seal across the main bore. The rams are in cavities formed in the body, the cavities are formed such that more than two rams can be disposed at the same elevation in the body thereby reducing the overall height of the blowout preventer stack. | 03-26-2015 |

20090150745 | TRAPPING SET DECODING FOR TRANSMISSION FRAMES - Trapping set decoding for transmission frames is disclosed. In one aspect, a trapping set decoder includes a decoder that performs decoding operations on an encoded codeword in received data, and a detector coupled to the decoder for detecting the presence of any one of a group of possible trapping sets in the decoding operations on the encoded codeword. A selection processor is also included, coupled to the decoder, for providing a decoded codeword by selecting one trapping set of the group of possible trapping sets, the selected trapping set being present in the decoding operations of the codeword, and by using the selected trapping set to produce the decoded codeword. | 06-11-2009 |

20140055621 | OPTIMAL CAMERA SELECTION IN ARRAY OF MONITORING CAMERAS - Technologies are generally described for automatically optimizing an efficiency of camera placement, numbers, and resolution in multi-camera monitoring and surveillance applications. In some examples, a fraction of a total area may be monitored at a higher resolution than the rest. Employing techniques such as combinatorial state Viterbi technique or combinatorial state trellis technique, a minimum number of cameras that provide the coverage at the needed resolution may be selected. Similarly, a number of points may be covered with at least a predefined number of cameras. For example, a subject of interest may be tracked in a public area, where specific camera(s) may be used to image the subject's face at a higher resolution than the background. | 02-27-2014 |
20150085188 | DE-INTERLACING AND FRAME RATE UPCONVERSION FOR HIGH DEFINITION VIDEO - Technologies and implementations for de-interlacing an interlaced digital video and up-converting a frame rate of a digital video are generally disclosed. | 03-26-2015 |
