  • Patent number: 11879086
    Abstract: A high internal phase emulsion stabilized by a low content of surfactant and its preparation method thereof are provided. An oil ethoxylate is added to a vegetable oil, and the resulting mixture is uniformly mixed under a low-speed stirring at room temperature. Water is added dropwise to the mixture of surfactant and vegetable oil under stirring, and a homogenization is performed on the obtained dispersed system by a high-shear dispersion emulsification homogenizer to obtain the high internal phase emulsion stabilized by oil ethoxylate. The preparation method requires a low content of surfactant, mild preparation conditions and simple operations. When the oil-phase volume fraction is 83 vol %, the minimum mass fraction of the oil ethoxylate to stabilize the high internal phase emulsion is 0.6 wt %, and the prepared oil-in-water type high internal phase emulsion has excellent stability and shows bright color, delicate odor, hydra feel and being easy to apply.

  • Publication number: 20240020866
    Abstract: The invention discloses a three-dimensional (3D) measurement method based on end-to-end deep learning for speckle projection. First, the speckle pattern was projected by the projector and collected simultaneously by the stereo camera. The speckle images after stereo rectification are fed into the stereo matching network. A feature extraction sub-network based on shared weights processes the speckle images to obtain a series of low-resolution 3D feature tensors, The feature tensor is fed into the saliency object detection sub-network to detect foreground information in the speckle images, producing a full-resolution valid mask map. A 4D matching cost volume is generated using the feature tensor of both views based on the candidate disparity range, filtered by a series of 3D convolutional layers to achieve cost aggregation, so that the initial disparity map is obtained by disparity regression.

  • Publication number: 20240015452
    Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.
