  • Patent number: 11965738
    Abstract: Disclosed is a data analysis-based intelligent deformation monitoring system for mountain landslides, which solves the technical problem in the prior art that when a landslide occurs in a landslide area, it is not possible to implement region-specific monitoring for landslide soil, thus failing to minimize the real-time impact of the landslide area. The present disclosure involves marking a sub-area where a landslide occurs as a landslide area, marking a real-time sliding direction within the landslide area as a landslide flow direction, setting areas at both sides of the landslide flow direction as landslide slopes, generating a control adjustment signal or a risk monitoring signal through landslide slope analysis, and sending the signal to a server.

  • Publication number: 20240072875
    Abstract: A multiple-input multiple-output (MIMO) receiver for Wireless Fidelity (Wi-Fi), and an electronic device. The MIMO receiver for Wi-Fi includes n antennas, an energy detection circuitry, a multilink gating circuitry, receiving links, a frequency offset adjustment circuitry, and a gating control circuitry. The multilink gating circuitry includes one energy detection gating output terminal coupled to the frequency offset adjustment circuitry through the energy detection circuitry and n-1 non-energy detection gating output terminals coupled to the frequency offset adjustment circuitry. The multilink gating circuitry connects each gating input terminal to one of the gating output terminals. The gating control circuitry periodically obtains a signal strength of each of the receiving links, and controls, based on the signal strength, the multilink gating circuitry to connect the gating input terminal corresponding to the receiving link that meets a preset condition to the energy detection gating output terminal.

  • Patent number: 10889874
    Abstract: A thick steel plate for high heat input welding and having great heat-affected area toughness and a manufacturing method therefor, comprising the steps of smelting, casting, rolling, and cooling. Chemical composition is properly controlled for the steel plate and satisfies 1?Ti/N?6 and Mg/Ti>0.017, where effective S content in steel=S?1.3 Mg?0.8 Ca?0.34 REM?0.35 Zr, and effective S content in steel: 0.0003-0.003%; finely dispersed inclusions may be formed in the steel plate, and the amount of composite inclusion MgO+Ti2O3+MnS in the steel plate is controlled at a proportion greater than or equal to 5%. The tensile strength of a base material so acquired is ?510 MPa, insofar as welding input energy is 200-400 kJ/cm, the average Charpy impact work of the steel plate at ?40 ° C. is 100 J or more, at the same time, the average Charpy aging impact work of the base material of ½ thickness at ?40° C. is 46 J or more.
