Title: Electronic tuning system
Inventor: WILLIAM REDMAN-WHITE
IPC: H04B5/00
Filed: 2016-06-25
Abstract: A system is provided that can automatically and continuously maintain an inductive-capacitive (LC) network at resonance while the frequency of an excitation signal 209 is varied between a number of discrete frequencies. The system permits the use of frequency modulation or frequency shift keying (FSK) to carry data in near field communication systems, including biomedical devices and wireless charging systems, while using a high-Q resonant antenna coil. The system automatically compensates for manufacturing tolerances and drift of component parameters due ageing and environmental factors. The error between the resonant frequency of the tuned circuit and the excitation frequency is determined in real time from signals within the system. The system may also be used to maintain the LC circuit at resonance while the excitation frequency is varied on a cycle-by-cycle basis between a number of discrete frequencies 1013-1014-1015, the effect of which is to permit phase modulation in discrete phase increments, or phase shift keying (PSK). The system allows the use of high Q antenna coils and fast phase modulation of the transmitted carrier signal. Such a scheme has the advantage of allowing substantially continuous power transfer.

Title: Method and system for compressing and decompressing digital three-dimensional point cloud data
Inventor: MARCIN KAMINSKI
IPC: G06T17/00
Filed: 2018-07-13
Abstract: Compressing (and/or decompressing) 3D image data (e.g. real world scene) comprising a point cloud (600), each point having one or more attributes, comprises encoding (620) the position data using an octree decomposition (610). Encoding the attribute data involves constructing (630) a relative neighbourhood graph (an undirected graph) for the points in each sub-octree partitioned from the octree, wherein the attributes of each point are signals on the graph. A combinatorial Laplacian matrix of each graph is calculated, as is an eigenvector decomposition for each matrix. A graph Fourier Transform of each attribute for each graph based on the corresponding eigenvector decomposition is then calculated (640), with a portion (e.g. at least 50%, 70% or 90%) of each graph Fourier Transform then being discarded. Each reduced graph Fourier Transform is compressed (650) (e.g. entropy encoded) to provide compressed point cloud attribute data, and a bit stream is generated corresponding to octree voxels occupancy. The bit stream is compressed (e.g. entropy encoded), providing (660) compressed point cloud position and attribute data. The octree may have a depth corresponding to a point cloud resolution level such that each voxel in the point cloud contains no more than one point.

Filed: 2018-09-10
Abstract: Receiving image data corresponding to an under-sampling of an image, which may be (a) represented in a non-spatial vector space (such as Fourier space, frequency space or k-space), wherein a first transform (e.g. a Fourier transform) exists for mapping the non-spatial representation of the image to a representation in a first spatial vector space (e.g. the standard image space). Preferably this representation comes from under-sampled magnetic resonance (MRI) data. Alternatively, the under-sampling of the image may be (b) represented in a number of second spatial vector spaces, wherein a second transform (for instance a back projection) exists for mapping the image representation to a representation in the first spatial vector space. Alternatively, the under-sampling of the image may be (c) represented in the first spatial vector space, wherein the representation in the first spatial vector space has been obtained by transforming representation (a) or transforming representation (b) using the respective first or second transform. Preferably the network is a convolutional neural network, or a TL-net architecture. The trained machine-learning model is configured to determine one or more parameters and/or segmentation maps of the representation of the image in the first spatial vector space, without reconstructing or estimating a fully-sampled image.
