Abstract: A fluid comprising a viscous hyposaline aqueous solution of first and second cationic polymers comprising quaternized anunonium groups, wherein the first cationic polymer comprises a hydrophilic base polymer structure and the second cationic polymer comprises a lipophilic base polymer structure, and a method comprising introducing the viscous fluid into an initial first interval of a subterranean formation, and diverting with the viscous fluid a treating fluid from the initial first interval to an initial second interval. The fluid and method are useful to modify a hydrocarbon reservoir formation for improved relative permeability of oil with respect to water to enhance hydrocarbon production from the reservoir.
Patent GB-2495468-A (GB)
Title: Frame Recovery Performed Over a Number of Frames Following a Loss Report
Inventor: NILSSON MATTIAS
IPC: H04N19/89
Filed: 2011-09-02
Abstract: A video comprising a plurality of image frames is encoded, including using inter frame encoding to encode at least portions of some of the frames, thereby generating an encoded video stream. The encoded stream is transmitted over a lossy channel for decoding at a receiver to produce decoded video. A recovery operation is performed to refresh the encoding of the video image, cutting off error propagation occurring in the decoded video due to effects of inter prediction in presence of loss over the channel. The recovery operation is triggered by a report fed back from the receiver indicating loss. The recovery operation is performed over a number of frames, refreshing the encoding of different partial frame regions at different respective frames (e.g. using Intra frame encoding or Inter frame encoding relative to a known error-free portion). The spreading of the recovery over numerous frames (a    soft recovery   ) rather than recovering in a single frame prevents bitrate overshoots and/or increased source code distortion. The whole of the video image may be refreshed over the number of frames. An error propagation distortion map may prioritise refreshing, and only the highest priority portions may be refreshed.

Title: Multiplexed DC offset compensation
Inventor: LESSO JOHN PAUL
IPC: H03F1/30
Filed: 2010-12-16
Abstract: In an audio amplifier, a DC offset compensation circuit is provided in which an offset compensating feedback path (107) comprises at least one voltage controlled oscillator (VCO) (108) and a counter (109). The VCO (108) provides, over time, a first VCO output signal based on the amplified output signal (Sout) and a second VCO output signal based on a reference signal (VREF). The counter (109) generates first pulse counts based upon the first VCO output signal and second pulse counts based upon the second VCO output signal and provides a compensation signal based on a comparison of the first and second pulse counts. The output signal of the counter (109) may be fed back via a DAC (112) or via digital paths (dotted). The low area occupied by the compensation circuit reduces the need to multiplex offset compensation across a large number of audio paths. In the present invention, the compensation circuitry is multiplexed between a first feedback loop for compensating offset in a first part of a signal path, and a second loop for compensating for offset in a second part of the signal path.

Filed: 2012-06-29
Abstract: Control bits for switches of a butterfly network are directly solved (314) iteratively for each successive functional column of switches to route data values in parallel according to a multiple access scheme through the butterfly network to memory spaces. A memory space address and appended bus index leading into the butterfly network arc generated. A linear order bus index and. a physical address are determined for a switch having an unsolved control bit. The solved control bits are applied to solve control bits to a next functional column in a linear order and an interleaved order by starting from the bus index and physical address. The linear order is moved to the interleaved order by a reduced turbo de-interleaver and the interleaved order is moved to the linear order by a reduced turbo interleaver.

Title: Determining mooring line tension from its elastic response
Inventor: JAMIESON ANGUS
IPC: B63B21/50
Filed: 2011-09-15
Abstract: Determining an elastic response of a mooring line (105, Fig.3) of a marine asset (e.g. oil rig 101, Fig.3) and determining the tension in the mooring line there-from. Elastic response may be determined 653 by generating a set of elastic response profiles for multiple tension values (e.g. for a particular seabed profile 659), measuring an elastic response profile of the mooring line and identifying 657 a generated profile that corresponds to the measured profile. An elastic response profile may be measured by determining 651a displacement between a connection point (102, Fig.3) on the asset and an anchor point (107, Fig.3) and the resultant change in tension on the mooring line. The determined tension may be used to calibrate 661 a tension meter and/or to derive mooring line position. The tension may be determined periodically or continuously during normal operations of the asset, e.g. drilling or hydrocarbon production.

Title: Updating a system of servers based on operating system compatibility
Inventor: WINTER MICHAEL GENE
IPC: G06F9/445
Filed: 2013-03-05
Abstract: A network comprising a number of servers is provided with software updates or add-ins 205. The system determines whether the current operating system configuration on each server is able to support the software 220; if the OS revision on all servers is compatible with the update 225, it is applied to the system 235 and incorporated into operations. This ensures that software upgrades do not affect the integrity of the server network by being added to an instance that does not support them. This update may be an incremental system update, and may be carried out in a way such that at least one of the servers remains operational whilst the others are being updated, so that maintenance downtime is not required. The system may prevent a new server from being added to the network if its operating system version is not compatible with the add-ins already being used; or it may bypass certain behaviours of the update that are incompatible with the operating system of the server.
