Filed: 2020-10-26
Abstract: Apparatus for assembling a pipe-in-pipe pipeline comprises a primary support system, such as an array of rollers 38, for supporting an outer pipe section 20 and a secondary support system, such as a set of rails 42, for supporting an inner pipe section (18).

The secondary support system is deployed to support the inner pipe section also centred on that common axis, enabling the inner pipe section to be advanced and welded to an inner pipe of the partially-completed pipeline. The secondary support system is then retracted to advance the outer pipe section, supported by the primary support system, around the inner pipe section. This enables the outer pipe section to be welded to an outer pipe of the partially-completed pipeline.

Title: Compressing a set of coefficients for subsequent use in a neural network
Inventor: MUHAMMAD ASAD
IPC: G06N3/08
Filed: 2020-12-22
Abstract: A method of compressing a set of coefficients 502 for use in a neural network, such as a convolutional neural network (CNN). Sparsity is applied to groups of coefficients, such as by setting each coefficient in the group to zero to produce a sparse group 506. Then each group is compressed according to a compression scheme aligned with the groups of coefficients to represent each group of coefficients by an integer number of compressed values. Each group of coefficients may comprise subsets of coefficients, with each group being compressed by representing each of its subsets by an integer number of compressed values. Sparsity may be applied based on a sparsity mask, which may be a binary tensor of the same dimensions as a tensor of the coefficients, by performing element-wise multiplication of the two tensors. The number of groups to which sparsity is applied may be determined by a sparsity parameter 504, such as by applying sparsity to groups of coefficients with a saliency below a threshold.

Title: Method, device, and computer program for dynamically encapsulating media content data
Inventor: Frédéric Maze
IPC: H04N21/854
Filed: 2021-06-29
Abstract: A method for encapsulating or parsing media data in which a first portion of the media data is organised into a first set of one or more media data tracks and encapsulated into media fragments; and associated metadata is encapsulated into a metadata portion. A second portion of the media data is organised into a second set of one or more media data tracks; and the second set of track and associated metadata are all encapsulated into one media fragment. An advantage of the invention is that a writer of a ISOBMFF file does not need to know all possible tracks when creating an initial MovieBox; instead the second portion of the media data is stored in a dynamic track which may be useful for additional media streams corresponding to additional languages, subtitles, camera views etc. Other aspects of the invention include encapsulating media data as a set of entities according to a parameter independent from the encapsulation, and signalling an indication to the client that the set of entities is to be parsed only if the client has knowledge about the parameter. The entities may be a set of corrupted samples.

Title: Calculating data compression parameters
Inventor: YERLAN IDELBAYEV
IPC: H04N19/94
Filed: 2021-11-17
Abstract: One or more circuits calculates one or more data compression parameters based, at least in part, on at least on one or more values of the data to be compressed in relation to at least two codebook entry values. An arrangement is disclosed wherein input data values are numerically sorted and used in conjunction with a codebook that is also numerically sorted to determine both a quantization scale parameter and assignment parameter from considering neighbouring entries in the numerically sorted codebook. In particular, intermediate points (midpoints) between neighbouring pairs of codebook entry values in the codebook are computed, and for each data value in the data to be compressed and for each intermediate point a quantization scale parameter is generated based on the data value and the intermediate point, based on the quantization scale parameter an assignment of the data values to the codebook entry values is calculated and a scale parameter is calculated based on the assignment and finally determining that one of the calculated scale parameters corresponds to a quantization scale parameter that minimises a quantization error in assigning the data values to the codebook entry values. Minimising a quantization error may involve minimising a mean-squared error, MSE.

Title: Diagonal wing strut oars
Inventor: RUPERT JOHN BICKHAM SWEET-ESCOTT
IPC: B64C31/028
Filed: 2022-01-12
Abstract: Disclosed is a flex wing or hang glider where the pilot can open and close the flex wing from the cockpit seat in the trike or undercarriage by using an extension of the diagonal wing strut as a lever arm. The extension may be telescopic. The pilot 5 may pull handle 4 to begin to open the wing by pivoting wing strut 1 at point 2. Pushing the extensions together closes the wing and pulling extensions apart opens it. The action is similar to using an oar on a boat where the diagonal wing strut 1 is the oar and the control frame pivot point 2 becomes the fulcrum. The extension may be used as an anchor point to fix a locking rope or cable to restrain the wing from fully closing, allowing the propeller to operate on the ground. The arrangement may reduce storage costs and allow operation on narrow roads or waterways.
