Title: Self-generating engine-specific health monitoring model from generic model base
Inventor: KEVIN MOECKLY
IPC: G07C5/00
Filed: 2019-11-26
Abstract: A method for self-generating an engine-specific model in an engine health monitoring system 402. The method comprises generating a physics-based engine model 409 for each engine components in the specific engine. The operating parameters of engine components and their environment, such parameters may be pressures, temperatures, speed, torque, fuel flow, airflow, airspeed etc, are detected by sensors during one or more pre-planned training missions. Data recorded data during the pre-planned training missions is used to train an engine-specific model 409, including physics-based model for each engine component. Historical data 407 is used for machine learning 408 such that predicted component parameters 410 can be forecast for set environmental parameters. If operational component parameters deviate from the estimated component parameter for a set environment, then a need for component maintenance is identified 414.

Title: Restored fairness in an 802.11 network implementing resource units
Inventor: Stéphane Baron
IPC: H04W74/08
Filed: 2016-07-13
Abstract: 802.11ax nodes benefit from additional medium accesses through multi-user uplink provided by an Access Point (AP), compared to legacy nodes, which can only transmit in a single-user, contention-based, EDCA channel. To restore fairness in medium access to the legacy nodes a node’s Enhanced Distributed Channel Access, EDCA, channel contention parameters, such as EDCA backoffs, are updated using penalty values each time a node successfully transmits data to the access point over Orthogonal Frequency Division Multiple Access (UL OFDMA) resource units (RUs). This reduces relatively the probability for the multi-user capable node to communicate also on the conventional EDCA channel compared to a legacy node. The access point may determine and communicate the appropriate parameters for the nodes in the network e.g. in a beacon frame or trigger frame. The contention parameters (e.g. penalty values) transmitted to the node may be determined based on a ratio of bandwidth usage of RUs relative to the total bandwidth usage of communication channels and RUs or a ratio of the number of resource units for which collision has occurred compared to the total number accessed or alternatively from information about data types from a history of received data types.

Title: Controlling rendering operations
Inventor: JOHN HOWSON
IPC: G06T15/00
Filed: 2019-05-31
Abstract: Methods of rendering a scene in a graphics system are described in which a draw call is identified within a current render and by analysis of the last shader in the series of shader the draw call can identify any buffers that are sampled by the last shader and that are to be written by a previous render that has not yet been sent for execution on the GPU. If any such buffers are identified, further analysis is performed to determine whether the last shader samples from the identified buffers using screen space coordinates that correspond to a current fragment location and if this determination is positive, adding the first draw call to both a merged control stream comprising draw calls from the previous render and a control stream for a current render. For a subsequent draw call in the current render, analysing at least a last shader in a series of shaders used by the subsequent draw call to identify any buffers sampled by tie last shader that are to be written by a previous render that has still to be sent for execution on the GPU and determining whether the last shader samples from the identified buffers using screen space coordinates that correspond to the current fragment location (104. 106) and in response to determining that the subsequent draw call does not sample from the identified buffers using screen space coordinates that correspond to the current fragment location discarding the merged control stream.

Title: Image rendering method and apparatus
Inventor: FABIO CAPPELLO
IPC: G06T15/06
Filed: 2021-03-24
Abstract: Embodiments of the present seek to replace the ray tracing step usually associated with image rendering with something else that has a more predictable computational load for a suitable quality of final image. The invention relates to an image rendering method comprising the steps of selecting at least a first trained machine learning model from among a plurality of machine learning models, the machine learning model having been trained to generate data contributing to a render of at least a part of an image, wherein the at least first trained machine learning model has an architecture based learning capability that is responsive to at least a first aspect of a virtual environment for which it is trained to generate the data, and using the at least first trained machine learning model to generate data contributing to a render of at least a part of an image. An example embodiment consists of a machine learning system for each contributing component of the image (e.g. diffuse, specular, and optionally coat or any other contributing component). The machine learning system is typically a neural network that is trained to learn a transform between the bi-directional scattering distribution function BSDF and the ray-traced ground truth of the contributing component of the image, for a plurality of images at different viewpoints in the scene. The machine learning system or neural network may learn to output a value that, when combined with the BSDF for that same position/pixel, results in a pixel value similar to that which would arise from raytracing the image at that pixel.

Title: Lattice formation of thermoplastic materials to model elastic behavior
Inventor: CHAD WILLIAM GLAESMAN
IPC: F16J15/3284
Filed: 2019-03-28
Abstract: A sealing assembly for use in a wellbore tool includes thermoplastic materials arranged in a lattice structure to provide a bulk elasticity on the order of elastomeric materials. The lattice structure permits an energizing element of the sealing assembly to deform sufficiently in the elastic range of the thermoplastic materials to provide repeatable sealing capabilities. The lattice structure may be constructed by additive manufacturing processes to include voids therein, which allow the thermoplastic members of the lattice to flex and bend. The energizing element may thereby exhibit a greater elasticity in bulk than the elasticity of the thermoplastic materials themselves. The lattice structure may be enclosed in an outer cover constructed of a polymeric, elastomeric or other material to facilitate the interaction between the seal assembly and the corresponding sealing surfaces of a downhole wellbore tool.
