  • Patent number: 11917412
    Abstract: A UE having a security context with an Initial AMF is able to accept an unprotected AUTHRQ, under certain circumstances, for a limited time. In one embodiment, a UE considers the security context to be temporary, which invokes rules or exceptions different than a permanent security context, such as the acceptance of an unprotected AUTHRQ from a Target AMF. The network may indicate to the UE the temporary status, or the UE may assume it. Alternatively, the UE may enable exceptions to the defined rules associated with the security context. In one embodiment, the UE receives a plurality of partial registration acceptance messages, each indicating a specific task or aspect of the overall registration has been completed. The UE may mark its security context temporary, or enable exceptions to the rules 10 associated with it, until a partial registration acceptance messages indicates AMF re-allocation is complete or is not required.

  • Patent number: 11906286
    Abstract: The invention discloses a deep learning-based temporal phase unwrapping method for fringe projection profilometry. First, four sets of three-step phase-shifting fringe patterns with different frequencies (including 1, 8, 32, and 64) are projected to the tested objects. The three-step phase-shifting fringe images acquired by the camera are processed to obtain the wrapped phase map using a three-step phase-shifting algorithm. Then, a multi-frequency temporal phase unwrapping (MF-TPU) algorithm is used to unwrap the wrapped phase map to obtain a fringe order map of the high-frequency phase with 64 periods. A residual convolutional neural network is built, and its input data are set to be the wrapped phase maps with frequencies of 1 and 64, and the output data are set to be the fringe order map of the high-frequency phase with 64 periods. Finally, the training dataset and the validation dataset are built to train and validate the network.

  • Patent number: 11893719
    Abstract: A single-shot differential phase contrast quantitative phase imaging method based on color multiplexing illumination. A color multiplexing illumination solution is used to realize single-shot differential phase contrast quantitative phase imaging. In the single-shot color multiplexing illumination solution, three illumination wavelengths of red, green, and blue are used to simultaneously illuminate a sample, and the information of the sample in multiple directions is converted into intensity information on different channels of a color image. By performing channel separation on this color image, the information about the sample at different spatial frequencies can be obtained.

  • Patent number: 11889405
    Abstract: A method performed by an Access and mobility Management Function (AMF). The method includes receiving from a Session Management Function (SMF) a request to establish User Plane (UP) for a user equipment's (UE's) protocol data unit (PDU) session. The request includes information indicating an access type. The method also includes, in response to the request, performing the steps of: determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access and, as a result of determining that the UE is in the idle state with respect to both a 3GPP access and a non-3GPP access, the AMF initiates paging of the UE by the 3GPP access, the paging initiation comprising transmitting to a Radio Access Network, RAN, node a page request to page the UE.

  • 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.
