  • Publication number: 20210118087
    Abstract: Embodiments of this application provide a watermark embedding method applicable to a three-dimensional (3D) field. By combining vertex data of an original 3D model and vertex data of a 3D watermark, and combining material data of the original 3D model and material data of the 3D watermark, the original 3D model and the 3D watermark can be synthesized into a 3D model. In addition, before and after watermark embedding, an appearance of the original 3D model can remain unchanged. This avoids impact of watermark embedding on the appearance and use value of the 3D model, and ensures a display effect of the 3D model. Further, a function of encrypting the embedded 3D watermark may be implemented, and the 3D watermark cannot be easily removed or modified. This can effectively ensure the copyright of the original 3D model, and better promote a digital asset such as the 3D model.

    Abstract: A preparation method for a temperature-responsive light reflecting coating is provided comprising: forming a main chain cholesteric phase liquid crystal polymer by a polymerization reaction between an acrylate liquid crystal and an amine, and coating the main chain cholesteric phase liquid crystal polymer on a substrate to form a light reflecting coating, wherein the acrylate comprises a chiral acrylate, and the reflection wavelength of the reflecting coating is determined by the content of the chiral acrylate liquid crystal and the polymerization degree of the main chain cholesteric phase liquid crystal polymer formed. The method may further comprise cross-linking the main chain cholesteric phase liquid crystal polymer to obtain a polymer network so as to form a solid coating. The present disclosure further provides a temperature-responsive light reflecting coating.

  • Publication number: 20200253549
    Abstract: A system and method of detecting a sobriety of a subject utilizing a mobile device. The mobile device includes a processor and a memory storing historical data including movements indicating a drunk state, movements indicating a sober state, or a combination of both. The mobile device further includes a user interface, a recorder operable to capture a recording, and an accelerometer operable to generate acceleration values of movements of the recording. When the mobile device captures the recording of a subject performing movements, the processor compares the data on the memory with the acceleration values of the movements of the subject and produces an indication of either a drunk state of the subject or a sober state of the subject on the user interface.

  • Publication number: 20200143539
    Abstract: The present invention relates to microbial sample and standard preparation, staining and labeling, imaging and data acquisition as well as a method and apparatus for distinguishing objects of interest from other objects and background in an optical field. A microbial genomic analysis tool, Spatial Analytical Microbial Imaging (SAMI), provides the spatiotemporal and comparative intracellular ploidy, indicating the relative growth rate of cells in situ. Objects in a 2D or 3D optical field are tagged using fluorescence marker DNA binding to specifically visualize and semi-quantify the targeted objects in the sample, which allows them to be identified characterized and counted. In particular, inferential comparative genomic copy number (relative vitality), which is the relative amplification rate of cells related to the copy of genomic compounds in the cell comparing to those of the pure culture standards, are determined.

  • Patent number: 10614299
    Abstract: This invention introduces an indoor person identification system that utilizes the capture and analysis of footstep induced structural vibrations. The system senses floor vibration and detects the signal induced by footsteps. Then the system then extracts features from the signal that represent characteristics of each person's unique gait pattern. With these extracted features, the system conducts hierarchical classification at an individual step level and at a collection of consecutive steps level, achieving high degree of accuracy in the identification of individuals.

  • Patent number: 10550416
    Abstract: The present invention provides a microbial genomic analysis tool, named Spatial Analytical Microbial Imaging (SAMI), which provides the spatiotemporal and comparative intracellular ploidy, indicating the relative growth rate of the cells in situ. Firstly, pure cultures of two microbial species were pre-evaluated for their validity using SAMI. Secondly, the same pure cultures were split aliquot to pure culture and mixed culture, and grown concurrently to reduce error. Another set of pure culture can also be grown as a standard to evaluate inferential comparative genomic copy number if necessary. Thirdly, the genomes of individual cells in the pure culture and the mixed culture are stained with membrane permeable fluorescent DNA markers and analyzed by confocal laser scan microscopy and an image software. The average fluorescent intensity (AFI) and the total genomic fluorescent biding area (GFA) of slow growth pure cultures indicate the population AFI and GFA using inferential statistics.

  • Publication number: 20190340185
    Abstract: Data is replicated between primary and secondary storage systems using a data pulling process or a log shipping process. If data is to be replicated through the log shipping process, a transaction and its associated data get stored in a transaction log in the secondary storage system. Subsequently, when the transaction gets executed, actual data gets persisted from the transaction log to a data log in the secondary storage system. If the data is to be replicated through the data pulling process, the transaction is stored in the transaction log. However, the associated data for the transaction is retrieved from the first primary storage system and stored directly in the data log in the secondary system.

  • Publication number: 20190036432
    Abstract: The present disclosure discloses a permanent magnet electric motor, which is a radial flux electric motor, consisting of a stator and a rotor, wherein an inner circle of the stator is provided with N stator teeth evenly in circumferential direction, each of the stator teeth is wound by a coil, and the N coils form stator windings, wherein, the N is an integer not less than 12. Additionally, the number of magnetic poles of the rotor is not less than 12 so that widths and the centrifugal forces of the magnets under each of the magnetic poles are limited, thereby facilitating the high speed operation of the electric motor and improving the safety. The stator is manufactured by laminating a plurality of annular thin sheets with a same shape, and the material of the annular thin sheets is an amorphous magnetic conductive material, whose power loss in an alternating magnetic field is lower than that of silicon steel, which hugely increases the efficiency of the electric motor.
