  • Publication number: 20240309960
    Abstract: The deluge valve assembly includes: a deluge valve, in which the deluge valve includes a water inlet cavity, a water outlet cavity, and a diaphragm cavity. The water inlet cavity is suitable for communication with the fire protection pipe network so as to make water from the fire protection pipe network flow into the water inlet cavity; a water inlet pipeline, in which an inlet of the water inlet pipeline is connected with the water inlet cavity, and an outlet of the water inlet pipeline is connected with the diaphragm cavity; a water outlet pipeline, in which an inlet of the water outlet pipeline is connected with the diaphragm cavity; reinforcement members, in which at least two of the deluge valve, the water inlet pipeline, and the water outlet pipeline are connected through the reinforcement members. The deluge valve assembly has advantages of good performance in anti-vibration and reliability.

  • Publication number: 20240134001
    Abstract: Embodiments of the present disclosure provide a method and apparatus for determining a noise floor estimated value, a target detection method and apparatus, and an electronic device. The determining method comprises: obtaining a two-dimensional Fourier data plane corresponding to a linear frequency modulation continuous wave, wherein the two-dimensional Fourier data plane comprises a distance dimension and a Doppler dimension, and the distance dimension comprises a plurality of distances gates; and for each distance gate, determining a noise floor estimated value according to a plurality of two-dimensional Fourier transform energy data of the distance gate along the Doppler dimension. According to the technical solution provided by the embodiments of the present disclosure, the noise floor estimated value of each distance gate is determined, and the efficiency and accuracy of the determined noise floor estimated value are improved.

  • Patent number: 10408855
    Abstract: Aspects of the disclosure provide a system for detecting a movement that includes a moving state detector, a profile-based movement state detector, and a refined movement state detector. The moving state detector is configured to generate a moving state based on a detected speed. The profile-based movement state detector is configured to determine an estimated movement state based on the moving state and detected accelerations. The refined movement state detector is configured to generate, in response to the estimated movement state corresponding to a predetermined triggering movement state, a refined movement state based on a detected angular velocity.
