  • Patent number: 11917373
    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.

  • Patent number: 11915311
    Abstract: A method, apparatus, and server for generating a user score based on social networking information is provided. In the disclosed method, by processing circuitry of an information processing apparatus, default annotation information of a plurality of sampled users, an ith user score and an ith relative user score for each of the sampled users are obtained. A user score model is trained according to the ith user score of the respective sampled user, the ith relative user score of the respective sampled user, and the default annotation information of the respective sampled user. An (i+1)th user score of the respective sampled user is subsequently calculated and a trained user score model, for each of the sampled users, is obtained when the (i+1)th user score for the respective sampled user satisfies a training termination condition, The method provides a solution to evaluate the user score for a use when personal information of the user is missing or incorrect.

  • 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.
