Abstract: This disclosure relates to the technical field of marine environment prediction, and in particular, to a method and system for multimodal fusion prediction of a marine environment based on digital twinning. The method includes the following steps: capturing spatiotemporal correlation features of multimodal data of the marine environment based on a dynamic multimodal graph neural network; performing multi-scale feature fusion on the spatiotemporal correlation features by using a multi-scale gating unit to obtain a comprehensive feature representation; predicating the comprehensive feature representation by using a hybrid time-series prediction framework to obtain preliminary marine environment prediction data, including short-term dynamic modeling and long-term trend modeling; and performing noise fitting on the preliminary marine environment prediction data by using a generative adversarial network to generate the final marine environment prediction data.

Abstract: A battery pack, including a housing, and a busbar support, a BMS board and a plurality of cells which are located within the housing. The busbar support includes a plate body and an aluminum busbar. The plate body and the aluminum busbar are injection-molded integrally. The aluminum busbar and the plate body are injection-molded integrally and the aluminum busbar serves as an electrically conductive busbar. In this way, during the process of injection-molding the aluminum busbar and the plate body into the busbar support, since the heat dissipation rate of aluminum is lower than that of copper and is close to that of an injection-molded material, cooling rates of the aluminum busbar and the plate body become consistent during cooling of the injection-molded busbar support, thereby reducing the probability of forming a gap between the plate body and the aluminum busbar and lowering the risk of fracture of the support.

This CMOS structure reduces the processing steps for fabricating the CMOS, thereby reducing the process complexity and the production cost, which is beneficial for improving the performance and reliability of CMOS and its integrated circuits.

Abstract: Methods and apparatus for monitoring chirp in a modulated light beam. The modulated light is passed through a variable dispersion element or “VDE”, and the light from the variable dispersion element is detected to yield a signal. A parameter which represents the strength of modulation in the light after passage through the VDE such as the peak intensity of the modulated light is measured as the VDE is controlled to vary the applied dispersion. The chip is determined from the variation of the parameter with dispersion, such as from the dispersions at which the parameter is at minima. The method can be applied to beams modulated by common digital transmitters used in optical communication systems.

Abstract: Aspects of the disclosure are directed to a system for incorporating a CVBG (Chirped Volume Bragg Grating) into a prism to form a P-CVBG (Prism-Chirped Volume Bragg Grating) optical element for channel dispersion compensation. A prism region is configured to receive optical signals with multiple wavelengths and provide the wavelengths to the CVBG region by spatially separating the optical signals into various wavelengths. The CVBG region is configured to compensate for dispersion of the multiple wavelengths by reflecting the various wavelengths at different depths within the gratings of the CVBG region.
