Title: Integrated system for distributed optical fiber sensing of hydraulic structure seepage, and method therefor
Inventor: HUAIZHI SU
IPC: G02B7/00
Filed: 2015-10-30
Abstract: An integrated system for distributed optical fiber sensing of hydraulic structure seepage, comprising a specially produced optical fiber for seepage measurement (143), an optical fiber calibration apparatus, an optical fiber laying apparatus, and a seepage identification apparatus. After the optical fiber calibration apparatus calibrates the specially produced optical fiber for seepage measurement (143) on site, the specially produced optical fiber for seepage measurement (143) is laid and tested by means of the optical fiber laying apparatus, and is connected to the seepage identification apparatus for information collection, processing and analysis after the test succeeds. The system can complete high-efficiency calibration of a long-distance optical fiber and reliable control and measurement of the bending curvature. By combining the specially produced optical fiber for seepage measurement (143), having a self-controlled heat source, and a seepage identification technology based on a femtosecond pulse, the seepage of a hydraulic structure can be sensed with high precision and high spatial resolution, at high sensing speed and at long distance. Also provided is a method for distributed optical fiber sensing of hydraulic structure seepage.

Title: Tracking hit and run perpetrators using V2X communication
Inventor: DANIEL A MAKLED
IPC: G08G1/017
Filed: 2018-05-22
Abstract: A host vehicle comprises hardware to monitor for collisions, crashes or other accidents (402) with target vehicles, and to determine whether the collision is a hit-and-run (406), and collect identification information (408) about the target vehicle. Should the collision be determined to be a hit and run, then a message is broadcast including the identifying information and a cascade duration (410). The determination as to whether the target vehicle has absconded may be achieved by the host vehicle setting a timer and threshold distance and determining whether the target vehicle distance exceeds the threshold distance within a threshold time. The location and/ or identification of the target vehicle may be determined by exchange of messages, or using sensors located on the host vehicle. The identifying information may comprise license plate number and/or make, model and colour of the target vehicle. The cascade duration may cause a bystander vehicle or roadside infrastructure to rebroadcast the message. A further vehicle may determine, based upon reception of the message, whether the target vehicle is in its vicinity. The further vehicle may then broadcast a message with updated target vehicle tracking information and cascade duration.

Title: Apparatus for, and method of, controlling the mixing of components of curable resin systems
Inventor: Darren James Eagles
IPC: G05D11/13
Filed: 2018-11-05
Abstract: A mixture control unit and weighing device are used by an operator initially to weigh a desired amount of resin. The mixture control unit then calculates the required addition of hardener to achieve the correct mixture ratio within a preset tolerance. If too much hardener is added by the operator, the mixture control unit then directs the operator to achieve the required subsequent addition of resin to achieve the correct mixture ratio within the preset tolerance. If too much resin is then added by the operator, the mixture control unit then directs the operator to achieve the required subsequent addition of hardener to achieve the correct mixture ratio within the preset tolerance. The mixture control unit utilises a feedback control to direct the operator iteratively to the correct mixture ratio within the preset tolerance. An apparatus suitable for carrying out the method is also disclosed.

Title: Method of three dimensional (3D) modelling a reservoir system using dip-domain boundaries
Inventor: EWAN BROCK
IPC: G06T17/20
Filed: 2020-08-03
Abstract: Defining an extended surface boundary description (SBD) comprises obtaining an initial SBD and extension distance. The SBD is transformed to a transformed SBD oriented such that its long-axis is parallel to a first direction and an average normal vector is parallel to a second direction, the directions being mutually orthogonal and defining a first plane, and wherein the transformed SBD comprises source vertices (V1, V2…) separated by boundary segments (S1, S2…). A bisector (i.e. initial extension vector, F1, F2…) is generated from each source vertex, projecting orthogonally to the first plane and bisecting an angle subtended by the adjacent boundary segments. A new bisector (F6 & F7) is generated (repeatedly if required) at each intersection point (IP12, IP14) of a pair of bisectors, when intersections occur within the extension distance. An extended boundary vertex (V1’ in Fig. 8) is generated on each bisector at the extension distance (d in Fig. 8), the extended SBD being generated by connecting the extended boundary vertices. An extended boundary region defined between the extended SBD and the transformed SBD is tessellated, and the region defined by the extended and initial SBDs is transformed such that the initial SBD is in its original location.

Title: System and method for recommending semantically relevant content
Inventor: ANGELOS PIKRAKIS
IPC: G06F16/783
Filed: 2020-10-02
Abstract: A property vector derived from extractable measurable properties of a data file is mapped to semantic properties for that data file. The property vector may be an output from a trained artificial neural network that, following pairwise training of the ANN using pairs of files that map pairwise similarity/dissimilarity in property space towards corresponding pairwise semantic similarity/dissimilarity in semantic space, both preserves and is representative of semantic properties of the data file. The system and method may assess, based on comparisons between generated property vectors, rank and then recommend and/or filter semantically close or semantically disparate candidate files in a database from a query from a user that includes the data file. Applications of the categorization and recommendation system and method apply to media or search tools and social media platforms, including media in the form of music, video, images data and/or text files.

Title: Maintaining inflatable product pressure
Inventor: SCOTT ABBOTT
IPC: G05D16/00
Filed: 2021-07-20
Abstract: An inflatable product 11 is connected to a control apparatus 10. An air flow generator 12 is operated by a motor 13 and supplies a flow of air internally to an inflatable product 11, such as bouncy castle or inflatable slide. A motor controller 21 controls the motor speed. In a low energy mode, the motor controller reduces the motor speed to maintain a lower pressure in the inflatable product 11. In a high energy mode, the motor controller increases the motor speed to maintain a higher pressure in the inflatable product 11. A sensor arrangement 18, 19 may be used to detect an internal pressure of the inflatable product 11, the internal pressure may be determined by monitoring the motor torque and/or speed of the air flow generator. The motor controller 21 may automatically adjust the motor speed depending on the monitored internal pressure. The air flow generator 12 may be a blower or a fan. The sensors 18, 19 may monitor parameters such as motor speed, torque, current, voltage and/or temperature. The adjustable fan speed makes the control apparatus compatible with continuous airflow inflatables having differing air loss / escape rates. The invention seeks to prevent underinflation or overinflation of inflatables.

Filed: 2022-01-12
Abstract: A model learning and sample value generating framework includes a system and method to comprehensively integrate encoding, decoding and value predicting, and optimizing functions to reconstruct as accurate as possible an original input sample data space. The system leverages a variational autoencoder model to generate as realistic samples of that data space as possible. The system learns a value prediction function to achieve a target outcome based on the latent feature data instead of the original input data. Further, the system solves the optimization problem in the latent space without constraints to avoid the difficulty in optimizing in the original sample data space. The generated optimal samples are as similar as possible to the real-world input samples. The system provides a flexible data generation mechanism which is suitable for various kinds of target outcome specifications.
