Title: Wading staff with internal lanyard with flo through perforations
Inventor: BARNETT BERNARD THOMAS
IPC: A45B9/00
Filed: 2013-05-24
Abstract: A wading staff/stick comprises a hollow tube D (made from, for example aluminium) and a lanyard/strap A made of stainless steel rope, which may be drawn into the inside of the staff/stick when not in use by means of a lead or metal weight F secured to one ends of the rope. When in use the lanyard may be pulled out of the staff through a hole in the top of the staff L, coming to a stop when the weight is abutted against the inside of the top of the staff. The top two thirds of the tube are perforated E, allowing water to freely pass through it and reducing the water pressure on the top half of the staff when it is submerged in a flowing current. The bottom of the staff is weighted with lead K to provide ballast and a hole H is provided above a base of the staff to allow water to drain from the staff. The bottom section of the staff is covered in a heavy plastic tube M to avoid rock damage to its external finish.

Title: Relightable texture for use in rendering an image
Inventor: IMBER JAMES
IPC: G06T15/55
Filed: 2014-10-13
Abstract: Relightable free-viewpoint rendering allows a novel view of a scene to be rendered and relit based on multiple views of the scene from multiple camera viewpoints. Cast shadows in the scene are handled to allow local occlusion to be taken into account when determining irradiance estimates for the sample positions in the scene. This is achieved by determining an initial estimate of irradiance by ignoring local occlusion, then using that initial irradiance estimate with knowledge of the scene geometry including visibility to determine an angle-dependent radiance estimate for the scene. This radiance estimate can then be used with the knowledge of the scene geometry to determine local irradiance estimates at the sample positions within the scene. The initial irradiance estimate is based on a global irradiance estimate of the scene and may involve using the surface normals at the sampling positions of the one or more surfaces of the scene and separating an initial texture into an intrinsic colour estimate and a corresponding shading estimate.
Patent GB-2523221-A (GB)
Title: Method of isolating ions
Inventor: HOYES JOHN BRIAN
IPC: H01J49/00
Filed: 2014-11-11
Abstract: Ions derived from chemical compounds in the same class are isolated using a linked scanning system comprising a mobility separator 4 and a mass-charge ratio filter 6. The temporal separation of the ions is removed after mass filtering, such as with an ion trap or a collision cell 8. This may reduce the required data storage and spectrometer resolution. Ions of the same functional group or with shared moieties, for example, may be isolated in this way. Ions may further be distinguished by switching from a fragmentation (daughter analysing) mode to a non-fragmentation (pre-cursor or parent analysing) mode and applying an analysis technique, such as MSE.

Title: Method of forming a Laminar composite structure
Inventor: VIMAL JAISWAL
IPC: B29C70/30
Filed: 2014-12-18
Abstract: A stack of composite layers 1-9 is assembled on a layup tool 10, each composite layer comprising a fibre-reinforced matrix material. The composite layers include an inner composite layer 1 and an outer composite layer 9. During assembly of the stack, a series of spacers 20, 22, 23 are placed in a selected part of the stack, each spacer comprising a spacer matrix material. Each spacer is sandwiched between a respective adjacent pair of the composite layers. The selected part of the stack forms a bulge, and the outer composite layer has a greater path length at the bulge than the inner composite layer. After assembly of the stack, a bend is formed in the stack with the outer composite layer towards an outside of the bend and the inner composite layer towards an inside of the bend, the bend in the stack coinciding with the bulge. During or after formation of the bend in the stack, excess matrix material in liquid form flows out of the bulge.

Title: Quorum based data processing
Inventor: TOMLINSON MARTIN
IPC: H04L9/08
Filed: 2015-02-04
Abstract: A method of quorum-based data recovery, wherein a processor receives a predetermined minimum number of quorum portions generated from original data. Each quorum portion comprises a respective partial encryption key, and at least one ciphertext portion generated by encrypting the original data using an associated encryption key formed from a defined combination of said partial encryption keys; and decrypting the received ciphertext portions using an associated decryption key formed from the defined combination of received partial encryption keys, to recover the original data. Preferably a Hash of the encryption key is generated. Alternatively the method may assign data values to each quorum portion which each identifies a solution to a respective one of a series of equations that encode dependencies between data values of the original data. Alternatively the decryption may be based on a number of participants and quorum portions required to reconstruct the decryption key.

Title: Optimized plenoptic image encoding
Inventor: HERVÉ LE FLOCH
IPC: H04N19/61
Filed: 2015-02-16
Abstract: Encoding a plenoptic image by decomposing the plenoptic image into multiple sub-aperture images, encoding a first sub-aperture image using a set of encoding parameters, and encoding a second sub-aperture image using a restricted number of parameters amongst the set of encoding parameters. Sub-aperture images may be collocated and built from pixels with the same coordinates in respective micro-lens light field images. Sub-aperture images may be indexed and organised into indexed layers. Encoding parameters, such as encoding modes, subdivision patterns or reference images, may be optimised before coding. Encoding modes may be discarded based on probability of use, coding efficiency or image position. Subdivision patterns may comprise patterns based on subdivision depth. Encoding types may be temporal, inter-layer predictive or spatial intra encoding. A linear rate-distortion performance indicator may be evaluated between first and second compression processes. The present invention decreases the run-time of encoding algorithms for plenoptic videos of light field imaging whilst keeping a good encoding ratio captured using a plenoptic camera comprising an array of micro-lenses between the image sensor and main lens of the imager.
