  • Patent number: 11771805
    Abstract: An injectable in situ pore-forming hydrogel system and its preparation method and use are provided. The injectable in situ pore-forming hydrogel system uses an injectable hydrogel as a continuous base phase, and isolated live cells and magnesium particles are distributed in the continuous base phase, where the injectable hydrogel is a precursor or prepolymer of hydrogel, which can form hydrogel by cross-linking. The injectable in situ pore-forming hydrogel system can be used to create pores while the gel encapsulates live cells, which makes use of both the injectability and porous structures of hydrogel, which is important for the repair of cavitary, surgically difficult and irregularly defective tissues; meanwhile, magnesium particles generate magnesium ions after the former undergoes gas production and degradation, which can improve the bioactivity of the gel and aid in tissue repair.

  • Patent number: 10622804
    Abstract: The present disclosure relates to a method for preventing a maloperation of differential protection of an optical fiber caused by saturation of a single Current Transformer (CT) of 3/2 connection. By applying a combination of the differential judgment and the sub-CT current judgment, reliable identification of internal and external faults is ensured, and the problem of misjudging of the internal fault as the external fault can be prevented as well.

  • Publication number: 20160320437
    Abstract: The invention relates to a frequency measuring method and measuring device. The method comprises: firstly sampling the current signal to be measured, and discretizing the sampled signals; secondly obtaining sampling matrixes [In] and [In,] of the current signal to be measured at time n and time n?1 from the discrete sampled signals, setting a reference frequency fref, constructing a reference voltage signal u(t) from fref, and discretizing u(t) to gain reference matrix; finally, attaining phase values of time n and time n?1 from the eigenvalues of matrixes [In]+[U] and [In?1]+[U], and determining a calculation frequency fcomp. The invention uses sampled matrixes constructed from the reference signals and the signals to be measured.
