  • Patent number: 12203440
    Abstract: A wave energy pressure amplification device includes a transmission chamber, a compression chamber, an oil storage chamber and a buoy. The transmission chamber is filled with hydraulic oil, a first slider is arranged on the hydraulic oil and connected to the buoy, and the buoy is used to drive the first slider to move in the transmission chamber. The transmission chamber is connected to the compression chamber via a first pipeline, and the oil storage chamber is filled with hydraulic oil and connected to the transmission chamber via a second pipeline. The compression chamber is connected to an air pipeline, and the air pipeline is provided with an air outlet one-way valve. The transmission chamber is driven by the buoy to drive the compression chamber to compress by hydraulic oil, and the pressure is continuously increased to reach the set value and discharged from the air outlet.

  • Patent number: 11519560
    Abstract: An improved mechanism for evaluation of degradation criticality is described. Corresponding apparatuses, systems, methods, and computer readable media are provided. The evaluation of corrosion criticality is utilized to estimate a failure pressure of a pipeline that is subject to structural degradation (e.g., metal loss corrosion). The evaluation, in some embodiments, is utilized with a specific tool configured for controlling or otherwise regulate pipeline operations responsive to the estimated failure pressure. The evaluation is a specific technical process whereby multiple failure paths through anomalies (structural defects arising from degradation features) are utilized in concert to determine an estimated failure pressure. The failure pressure, in some embodiments, is used to control actuation of one or more valve regulator features or to guide excavation.
