Abstract: Embodiments of the disclosed systems and methods provide for determination of roadway traversability by an autonomous vehicle using real time data and a trained traversability determination machine learning model. Consistent with aspects of the disclosed embodiments, the model may be trained using annotated birds eye view perspective data obtained using vehicle vision sensor systems (e.g., LiDAR and/or camera systems). During operation of a vehicle, vision sensor data may be used to construct birds eye view perspective data, which may be provided to the trained model. The model may label and/or otherwise annotate the vision sensor data based on relationships identified in the model training process to identify associated road boundary and/or lane information. Local vehicle control systems may compute control actions and issue commands to associated vehicle control systems to ensure the vehicle travels within a desired path.

Abstract: Embodiments of the disclosed systems and methods provide systems and techniques for improving reference route and/or trajectory information for autonomous vehicles that may allow for better operation and/or deployment. In certain embodiments, various optimization techniques may be employed for generating higher quality reference route and/or trajectory information based on initial reference route and/or trajectory information captured by an autonomous vehicle. Various embodiments of the disclosed systems and methods may improve reference route and/or trajectory information through processes that may involve editing and/or otherwise modifying initial route and/or trajectory information, smoothing path curves associated with initial reference route and/or trajectory information, modifying initial route and/or trajectory information based on vehicle-specific dynamics and/or parameters, and/or modifying velocities for improved passenger comfort.

Abstract: Real-time monitoring of surroundings of a marine vessel. One or more observation sensor modules are configured and positioned to generate sensor data extending around the marine vessel. One or more data processors are configured to map and visualize the sensor data in relation to a virtual model of the marine vessel. A user interface is configured to display the virtual model together with the visualized sensor data from a user selectable point of view to a mariner of the marine vessel.

Abstract: A single-disc refiner (1) has a stationary refining element (2) and an opposed rotatable refining element (12), each of which has a radially inner blade element (4, 14) providing an inner refining surface area and a radially outer blade element providing an outer refining surface area. The inner and outer refining surface areas of each refining element together provide a refining surface of the refining element, the refining surfaces defining a feed zone (29) followed by a treatment zone (30) with a transition point therebetween located at a radial distance of 70-90% from the center of the refiner or at a radial distance of 50-80% from the innermost edge (25, 27) of the refining element or at a radial distance of 20-50% from the inner edge (34) of the outer blade element (8, 18, 33) towards the outermost edge (26, 28, 35) of the refining element.
