Abstract: This disclosure includes subsea pumping apparatuses and related methods. Some apparatuses include one or more subsea pumps, each having an inlet and an outlet, and one or more motors, each configured to actuate at least one pump to communicate a hydraulic fluid from the inlet to the outlet, where the subsea pumping apparatus is configured to be in fluid communication with a hydraulically actuated device of a blowout preventer. Some subsea pumping apparatuses include one or more of: a desalination system configured to produce at least a portion of the hydraulic fluid; one or more valves, each configured to selectively route hydraulic fluid from an outlet of a pump to, for example, a subsea environment, a reservoir, and/or the inlet of the pump; and a reservoir configured to store at least a portion of the hydraulic fluid. Some apparatuses are configured to be directly coupled to the hydraulically actuated device.

Abstract: An online gaming service is provided, having two or more servers, the two or more servers being located in two or more locations that are remote from each other, including: a transaction layer implemented across the two or more servers, for handling synchronization between different sessions of a video game that are respectively executed by the two or more servers; wherein the different sessions of the video game are respectively configured to provide interactivity with a virtual space through respective client devices; wherein the transaction layer is configured to identify sessions providing interactivity with proximate regions of the virtual space, and effect transactional memory synchronization for the identified sessions, such that events in the virtual space generated by the identified sessions are synchronized across each of the identified sessions.

Abstract: Some embodiments of the present inventive concept provide for improved telepresence and other virtual sessions dynamic scaling and/or assignment of computing resources. An XR telepresence platform can allow for immersive multi-user video conferencing from within a web browser or other medium. The platform can support spatial audio and/or user video. The platform can scale to hundreds or thousands of users concurrently in a single or multiple virtual environments. Disclosed herein are resource allocation techniques for dynamically allocating client connections across multiple servers.

Abstract: Some embodiments of the present inventive concept provide for improved telepresence and other virtual sessions using localized projection of audible noises and/or dynamic adjustment of audio and/or video qualities based on spatial relationships between users. An XR telepresence platform can allow for immersive multi-user video conferencing from within a web browser or other medium. The platform can support spatial audio and/or user video. The platform can scale to hundreds or thousands of users concurrently in a single or multiple virtual environments. Disclosed herein are quality-of-service techniques for dynamically selecting or modifying audio and/or video traffic.
