Title: Generation of a sequence of textures for video delivery
Inventor: GWENDAL SIMON
IPC: H04N19/85
Filed: 2020-01-21
Abstract: Techniques and systems are provided for generating a video from texture images, and for reconstructing the texture images from the video. A first texture image configured for application to at least a three-dimensional mesh is divided into a first plurality of tiles. These tiles are then sorted into a sequence of ordered tiles and the sequence then provided to an encoding means for generation of a coded video on the basis of the ordered sequence of tiles. The tiles may be sorted on the basis of similarity e.g. the sum of dissimilarities between consecutive tiles being minimised or on the basis that the order minimises the number of video segments needed to be downloaded to obtain the first texture image. The invention may also involve dividing a second texture image which may be temporally independent and/or of different resolutions, into a second plurality of tiles and the second sequence into a second ordered sequence with the video is generated on the basis of both sequences. The video may be coded using motion compensation, inter-prediction between tiles. A transform may be applied to the tiles to increase the similarity between pixels of tiles. A data file including contextual data for the plurality of tiles may be generated and may include tile identifier, texture identifier, tile location data and/or a transform indicator.

Title: A drive shaft for a surgical instrument
Inventor: DANIEL THOMAS
IPC: A61B17/29
Filed: 2020-04-24
Abstract: The present invention provides an improved drive shaft for controlling an end effector of surgical instrument. Specifically, the drive shaft comprises two separate elements 12a, 12b (Figure 2), each comprising a triangular, spade-like flange 16a, 16b at its proximal end for restricting the lateral movement of the drive shaft when installed within an outer shaft 40 (Figure 8) of the instrument. The dimensions of the flanges are such that they fit within the outer shaft with minimal clearance, and that they extend in directions perpendicular to the length of the drive shaft, in different directions. This allows the drive shaft to be moved longitudinally within the outer shaft to actuate an end effector whilst minimising any lateral movement. This consequently prevents the end effector from tilting as it is actuated. The drive members are preferably arranged so that the flanges extend in opposite directions perpendicular to the length of the drive shaft. This helps to improve ease of assembly and provides space within the outer shaft for features such as connection wires, cutting blades and the like.
