Title: Latency mitigation system and method
Inventor: FABIO CAPPELLO
IPC: G06N20/00
Filed: 2020-11-10
Abstract: A model to select actions to be taken by an agent within an environment is trained by: determining 1100 a state of the environment; determining 1110 respective latencies associated with interactions between the agent and the environment; generating 1120 actions to be performed by the agent in dependence upon the state for each determined latency; evaluating 1130 the success of each action; and generating 1140 the model in dependence upon identifying correlations between the success of each of the actions and the determined latency associated with those actions, so as to identify an action to be taken by the agent in dependence upon both a determined state and a latency. The model is reinforcement learning or supervised learning. Latencies comprise network and processing latencies. Scores are assigned to actions indicative of compliance with conditions for success including parameters (speed, capabilities, battery power) and rules on objectives associated with the agent. Applications include: games; and control for navigational purposes along physical or virtual roads (or both in augmented reality) where paths and routes are taken by cars, drones, persons.

Title: Localization of vehicles using beacons
Inventor: Yih-Jye Hsu
IPC: G01S19/46
Filed: 2021-01-04
Abstract: Vehicles are localized using mobile beacons where a processor of a vehicle 501 determines that external signals for estimating the position of the vehicle are lost, degraded, or are predicted to be lost in the near future e.g. based on current location and map data. A set of mobile beacons 503a-c available to assist in estimating the position of the vehicle are determined. Using a communication device of the vehicle, broadcast signals from the set of mobile beacons are received, including localization data for the beacons. A subset of localization data from the set of mobile beacons is determined and used to estimate position of the vehicle. The subset may be determined using position uncertainty or dilution of precision (DOP) metrics. The external signals may be from fixed beacons, cell towers, routers or GNSS satellites. The signals may be lost in tunnels 502 or dense urban environments. The vehicle may be autonomous and nearby vehicles 503a-c can be used as mobile pseudolite beacons to decrease localization errors in GNSS denied areas 502.

Abstract: A method of preparing a copper(II) oxide, CuO, nanowire loaded copper mesh comprises dissolving persulfate and alkaline hydroxide into water and stirring to obtain a mixed solution. A red copper mesh is immersed into the mixed solution, reacting to form a copper(II) hydroxide, Cu(OH)2, nanowire grown copper mesh. The copper hydroxide nanowire mesh is heat treated to obtain the copper oxide nanowire loaded copper mesh. Preferably, the hydroxide is either sodium hydroxide or potassium hydroxide and the persulphate is selected from ammonium persulfate, sodium persulfate and potassium persulfate. The red copper mesh may be cleaned and pre-treated by immersion and ultrasonic cleaning sequentially in each of acetone, hydrochloric acid solution, and ethanol; cleaning to neutrality may be performed before the ethanol step. The produced mesh may be used in solar energy vapour generation. By growing the CuO nanowires in situ, the material is intended to provide high photothermal conversion performance.

Title: Low complexity enhancement video coding
Inventor: GUIDO MEARDI
IPC: H04N19/30
Filed: 2020-03-18
Abstract: A bitstream for transmitting one or more enhancement residuals planes suitable to be added to a set of preliminary pictures obtained from a decoder reconstructed video, comprises a decoder configuration for controlling a decoding process of the bitstream, and encoded enhancement data comprising encoded residual data representing differences between a reference video frame and a decoded version of the video frame (as per LCEVC / MPEG 5). The decoder configuration comprises scaling mode parameter(s), wherein each scaling mode parameter indicates a transform matrix that should be used for decoding coefficient groups of transform coefficients. The enhancement coding may operate on top of a base layer, which may provide base encoding and decoding. Spatial scaling may be applied across different layers. Only the base layer encodes full video, which may be at a lower resolution. The enhancement coding instead operates on computed sets of residuals. The sets of residuals are computed for layers, which may represent different levels of scaling in one or more dimensions. Encoding / decoding tools are described, which may involve applying transformations, quantization, entropy encoding and temporal buffering. At an example decoder, encoded base and enhancement stream(s) may be independently decoded and combined to reconstruct a video.
