  • Patent number: 11841304
    Abstract: A device and method for testing an effective diffusion coefficient of helium in helium-bearing natural gas solves the problem that there is currently no systematic method or supporting experimental device to quantitatively characterize the diffusion behavior of helium in helium-bearing natural gas. The device includes a diffusion system and a gas sampling and analysis system. The diffusion system includes an upstream diffusion chamber, a downstream diffusion chamber, and a true triaxial apparatus, and is configured to simulate a gas diffusion process. The gas sampling and analysis system includes an upstream gas sample retention chamber, a downstream gas sample retention chamber, and a chromatographic analyzer, and is configured to sample a diffusing gas and analyze composition of the gas. By performing diffusion process simulation, gas sampling and analysis, and data calculation and fitting, the effective diffusion coefficient of helium in the helium-bearing natural gas is finally acquired.

  • Publication number: 20230221409
    Abstract: Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.

    Abstract: A light-emitting device, a material screening method and a display panel. The light-emitting device of a first aspect of the present application includes a light-emitting layer including a host material and a guest material. When a carrier is injected into the light-emitting layer, there is a defect energy Et between the host material and the guest material, and an absolute value of the defect energy Et is greater than or equal to 0.03 eV. A light-emitting efficiency of the light-emitting device in a high-luminance state is improved and an operating voltage of the light-emitting device is reduced, which can ensure a display quality of the display panel in the high-luminance state and reduce an overall power consumption of the display panel.

  • Patent number: 11645765
    Abstract: Embodiments described herein provide various examples of real-time visual object tracking. In another aspect, a process for performing a local re-identification of a target object which was earlier detected in a video but later lost when tracking the target object is disclosed. This process begins by receiving a current video frame of the video and a predicted location of the target object. The process then places a current search window in the current video frame centered on or in the vicinity of the predicted location of the target object. Next, the process extracts a feature map from an image patch within the current search window. The process further retrieves a set of stored feature maps computed at a set of previously-determined locations of the target object from a set of previously-processed video frames in the video. The process next computes a set of correlation maps between the feature map and each of the set of stored feature maps.
