Title: Device to insert a flexible member into pressurized wellhead housing
Inventor: JENNINGS CHARLES E
IPC: E21B19/22
Filed: 2009-06-26
Abstract: A drive assembly for inserting hose within a wellhead housing that intermittently reciprocates the hose feed into the housing. The intermittent reciprocating action feeds the hose past obstacles in the wellhead housing, such as within annuluses between tubulars. The drive assembly includes rollers that frictionally contact the hose and when rotated drive the hose forward. The rollers are rotated by a drive sprocket that is rotated by a hand crank. An offset cam assembly between the hand crank and the drive sprocket adds an orbital/reciprocating motion to the drive assembly.

Title: Video Coding and Decoding Using Compression Control Rules
Inventor: MRAK MARTA
IPC: H04N7/26
Filed: 2012-06-19
Abstract: An image to be encoded is divided into blocks, and image intensity values in at least some blocks are transformed to provide transform coefficients which are quantised with quantisation parameters to derive a compressed bitstream. The encoding comprises selecting a compression control rule (e.g. Intensity Dependent (ID) profile), and for an image area, identifying a compression control parameter (e.g. image intensity for the area), the parameter varying between at least some image areas. Values (e.g. compression of the dynamic range) in the image area are varied in accordance with the rule operating on the control parameter, and the selected rule is signalled in association with the compressed bitstream for use at the decoder. At the decoder, the rule is extracted from the compressed bitstream and - after performing inverse quantisation and an inverse transform to form image values - those image values are inverse scaled.

Title: Restoring redundancy in a RAID
Inventor: FAIRHURST MATTHEW JOHN
IPC: G06F3/06
Filed: 2012-06-22
Abstract: A distributed storage system (such as RAID redundant array of inexpensive disks) comprising groups of RAID drives storing extents across said group, has a multitude of spare disks in case of a failure in one of the drives. On detection of such a failure, one of the spare drives is swapped into the RAID. If the storage capacity of the spare drive is smaller than that of the RAID, then a determination is made as to whether the extents that are higher on the RAID drives can be migrating to a lower position such that they fit within the size of the spare disk. If it is possible to migrate the extents, they are moved to a lower position and the spare disk is used as part of the RAID. This has the effect of reducing the capacity of the RAID, but maintaining the redundancy.

Title: Video Data Encoding / Decoding with Different Max Chrominance Quantisation Steps for 4:2:2 and 4:4:4 Format
Inventor: GAMEI JAMES ALEXANDER
IPC: H04N11/00
Filed: 2012-06-22
Abstract: Video coding / decoding quantises blocks of frequency-transformed luminance and chrominance component video data in a 4:4:4 or a 4:2:2 format according to a selected quantisation parameter which defines a quantisation step size. A quantisation parameter is defined as an association between luminance and chrominance quantisation parameters. The association is such that a maximum chrominance quantisation step size is less than a maximum luminance quantisation step size for the 4:2:2 format, but equal to the maximum luminance quantisation step size for the 4:4:4 format. Each component of the frequency-transformed data is quantised according to a respective value derived from the respective quantisation step size and the result is rounded to an integer value to generate a corresponding block of quantised spatial frequency data.

Abstract: To avoid overloading a viewer with visual stimuli when using hyperlinks within online video, a video player for tagged online video comprises: means for receiving a stream of video data and tag data, the tag data comprising details of plural tags including, for each tag, a link to display during video playback and a location (position) at which to display the link; and a video display output adapted to display: the video data, a user-selectable tag display graphical user interface (GUI) option (e.g. icons 28 tags always on, 30 tags sometimes on, 32 tags always off), and selectively, the tag data (24, Figure 1); and means for receiving information about a GUI pointer (e.g. mouse) location relative to the displayed video. Based on the option selected, tags (e.g. with associated actions such as opening a pop-out window or hyperlink to other data) are displayed during video playback; alternatively, tags are displayed during playback of the video data only if a GUI pointer (mouse) 22 is proximate (near) the tag location 34. Thus, the user can choose to display tags either all the time, or just when they are actively interacting with the video.

Title: Detecting heat capacity changes due to surface inconsistencies using high absorbance spectral regions in the mid-ir
Inventor: MYRICK MICHAEL L
IPC: G01N21/55
Filed: 2011-05-04
Abstract: Methods and systems for detecting the presence of an inconsistency in or on a surface are generally provided. The method can include directing a modulated light beam (e.g., having a wavelength of about 3 Âµm to about 20 Âµm) from a light source to a mirror. The mirror then directs a reflected light beam onto the surface (e.g., directly onto the surface or indirectly onto the surface via a additional mirror(s)). The mirror is controlled to scan the reflected light beam across the surface. A specular reflection from the surface can then be detected in each light cycle, and the presence of the inconsistency on the surface can be detected.

Alternatively, the same crosslinked cation exchange polymer is in the form of substantially spherical particles having a mean diameter of less than 250 microns and less than 4 volume percent of the particles having a diameter of less than 10 microns, and the polymer has a swelling ratio of less than 10 grams of water per gram of polymer, and a hydrated and sedimented mass of polymer particles has a viscosity of less than 1,000,000 Pa, the viscosity being measured at a shear rate of 0.01 sec-1. The preferred polymer to be crosslinked is poly(Î±-fluoroacrylic acid) in salt form. The preferred crosslinking agent is divinylbenzene (DVB). The crosslinked cation exchange polymers have beneficial physical properties, including combinations of particle size, particle shape, particle size distribution, viscosity, yield stress, compressibility, surface morphology, and/or swelling ratio. The polymers may be formulated into pharmaceutical compositions, such as with a linear polyol, especially sorbitol and/or xylitol. These polymers and/or compositions bind to potassium in the GI tract, and are thus are particularly useful for the treatment of hyperkalemia.
