  • Patent number: 11982633
    Abstract: The present disclosure provides a method for analyzing the signal of a neutral atom imaging unit, including: preparing a neutral atom imaging unit, which includes a semiconductor detector array and modulation grids disposed at intervals in front of the semiconductor detector array; preparing a neutral atom source plane, energetic neutral atoms emitted by the neutral atom source plane are received by the semiconductor detector array after passing through the modulation grids, and the modulation grids form a projection on the semiconductor detector array; obtaining a response function of the imaging unit according to the projection; calculating the data signal obtained by the neutral atom imaging unit; and performing inversion imaging on the neutral atom emission source according to the response function of the imaging unit and the data signal. The method well inverts the neutral atom emission source to obtain the intensity and size of the neutral atom emission source.

  • Publication number: 20240052955
    Abstract: A faucet includes a base and a spout. The base is configured to be coupled to a mounting surface. The spout is rotatably coupled to the base. The spout includes a plurality of magnetic joints each including a different number of magnetic members, and a plurality of conduits rotatably coupled to each other by a magnetic joint of the plurality of magnetic joints. The spout extends from the base to a free end configured to discharge a fluid. The plurality of magnetic joints are arranged such that the number of magnetic members on each magnetic joint progressively increases from the free end to the base.

  • Patent number: 10890277
    Abstract: A water delivery device includes a plurality of magnetic joints each including a plurality of magnetic members, and a plurality of conduit sections each rotatably coupled to each other by a magnetic joint of the plurality of magnetic joints. The plurality of conduit sections collectively define a spout of the water delivery device. The spout extends from a first portion configured to be coupled to a mounting surface to a second portion configured to discharge a fluid. The water delivery device is configured such that magnetic joints located closer to the first portion include a greater number of magnetic members than magnetic joints located closer to the second portion.
