Title: Determining geodetic positions of points on geophysical survey streamers towed at different depths
Inventor: SUDOW GUSTAV GORAN MATTIAS
IPC: G01V1/38
Filed: 2012-03-07
Abstract: Geodetic positions of a plurality of positions along at least two of a plurality of first streamers 14 towed in the body of water are determined. This may be done by making use of global navigation signal receivers (GNSS) 18 on tailbuoys 16. There may also be a GNSS receiver proximate the towing vessel. Distances between selected pairs of these determined positions, and between these positions and points on a second streamer 22, may be determined using acoustic range detection transceivers 20. This enables geodetic positions of the points on the second streamer to be determined by trilateration. The first streamers 14 may be seismic streamers, whilst the second streamer comprises electromagnetic sensors. The first streamers may include depth sensors; the distance measurements can be used to determine depth of the second streamer.

Title: Image encoding and decoding methods based on comparison of current prediction modes with reference prediction modes
Inventor: FRANCOIS EDOUARD
IPC: H04N19/593
Filed: 2012-04-13
Abstract: Methods and devices are disclosed for encoding or decoding mode information representing a prediction mode for a current image portion by an intra mode coding process, the mode being one of plural prediction modes. In one aspect, the current image portion prediction mode value to be encoded is compared S1003 with reference (e.g., most probable mode (MPM) or a planar mode) prediction mode values derived from prediction modes of respective image portions to determine (select) from plural encoding processes; if the current mode value is different from reference prediction mode values, the current image portion prediction mode value is compared S1004 with a further predefined prediction mode value, e.g. horizontal, vertical or DC prediction mode. In another aspect the method includes deriving a first reference prediction mode based on the prediction mode value of a single or at least two reference image portion(s). Alternatively, the mode information is represented by an angular index of the angular direction of the current prediction mode; where the current angular index value is different to reference angular indexes, the angular index value of the current image portion is coded. Codeword flags may be used.

Title: Feeding back scaled beamforming vectors to a MIMO transmitter
Inventor: TONG FEI
IPC: H04B7/06
Filed: 2012-07-09
Abstract: This disclosure concerns the feed back of beam-forming vectors and beam-forming matrices for multiple-input, multiple-output (MIMO) communications systems. A beam-forming matrix comprises a plurality of column vectors, each relating to a respective spatial stream of the MIMO system. Each vector comprises a series of elements; each element specifying a beam-steering weight for a respective transmit antenna of the transmitter. The invention lies in calculating a scaling factor, for each transmit beamforming vector, which scales each element of the respective vector. The scaling factor is selected to ensure that one element of the vector is scaled to unity. In one embodiment the element with the largest magnitude is selected to be the element scaled to one. In another embodiment the element scaled to â  1â   occupies a predetermined position within the vector. It is not necessary to send feedback values for the elements scaled to unity. Preferably, the scaled vectors are quantized before they are fed back to the transmitter. An alternative embodiment is concerned with performing a re-orthogonalisation process at the transmitter to restore orthogonality of beamforming vectors within the beamforming matrix, lost through the quantisation process.

Title: Mechanism for wireless communication
Inventor: NUSAIRAT ASHRAF
IPC: H04W88/08
Filed: 2014-03-27
Abstract: A wireless access point in communication with one or more stations is configured to shift the start of transmission of its downlink data. The access point may automatically shift the transmission of the downlink data (750) in response to receiving downlink data (720) transmitted by a neighbouring access point. If data received during a first transmission window is aligned with the start of said window then the access point time shifts the data transmission from the start of a second transmission window. Shifting the start of transmission of its downlink data permits stations to correctly synchronize to the downlink data. The transmission of data may be synchronized to a synchronization event. In some instances, the access point updates its downlink data with a value corresponding to the shift. The access point may not shift the transmission of the downlink data if the signal strength of the received downlink data is below a threshold.
