Abstract: The disclosure discloses a solid fluidization tubular separator for marine natural gas hydrate, which includes a first separator and a second separator, wherein the first separator includes the first separation sleeve, the power liquid pipe, the swirl baffle, the recovery mechanism and the sand discharge mechanism. After the hydrate is sucked into the first separation sleeve to generate a circumferential velocity, so that the mud and sand with high density are separated to the pipe wall of the first separation sleeve, and the mud and sand separated to the pipe wall are settled down from the gap between the swirl baffle and the pipe wall along the pipe wall. The hydrate swirl flows into the recovery mechanism, and then leaves the first separation sleeve and enters the second separator, so as to realize the separation of mud and sand and natural gas hydrate.

Abstract: In an approach to quarantining source code to prevent confidential information exposure, one or more computer processors store a pushed codebase associated with a user to an isolated quarantine area, wherein access to the quarantine area is restricted to the user through user interface code visibility enforcement and protocol code visibility enforcement. The one or more computer processors dynamically adjust a timeout period based on codebase complexity, user preferences, associated dependencies, codebase size, minimum execution temporal period for one or more scans, and system specifications. The one or more computer processors responsive to identifying one or more instances of confidential information, perform one or more remedial actions.

Abstract: Disclosed are techniques for quantifying body postures of a player employing a loop drive technique to strike a ball, such as performed in table tennis activities. A video recording of a player striking a ball with a loop drive technique is received and divided, using image processing techniques, into two segments: the first concerning player body postures before the ball is hit, and the second concerning body postures from the moment of impact between the ball and racket and the subsequent follow-through body postures. Then, image processing techniques are again leveraged to isolate and quantify specific body postures contributing to a loop drive technique in a given segment.

Abstract: Techniques for reliable clock speed change and associated circuits and methods are disclosed. Internal voltage supplies of semiconductor devices may include oscillators and charge pump circuits. The oscillator may include at least two clock paths for generating clock signals having different clock frequencies, which can be provided to the charge pump circuit. Further, the oscillator may generate a reset signal configured to activate one clock path over the other (e.g., changing clock speeds). In some embodiments, the oscillator includes a flip-flop to align the reset signal with respect to an edge of an input clock signal supplied to the oscillator such that unintentional (undesired, unexpected) features in the output signal of the oscillator can be avoided when the oscillator changes clock speeds.
