  • Patent number: 11577480
    Abstract: A method and apparatus for mass production of AR diffractive waveguides. Low-cost mass production of large-area AR diffractive waveguides (slanted surface-relief gratings) of any shape. Uses two-photon polymerization micro-nano 3D printing to realize manufacturing of slanted grating large-area masters of any shape (thereby solving the problem about manufacturing of slanted grating masters of any shape on the one hand, realizing direct manufacturing of large-size wafer-level masters on the other hand, and also having the advantages of low manufacturing cost and high production efficiency). Composite nanoimprint lithography technology is employed (in combination with the peculiar imprint technique and the composite soft mold suitable for slanted gratings) to solve the problem that a large-slanting-angle large-slot-depth slanted grating cannot be demolded and thus cannot be manufactured, and realize the manufacturing of the slanted grating without constraints (geometric shape and size).

  • Publication number: 20220109326
    Abstract: The present invention relates to a quick-response voltage control method of distribution systems considering multiple participants, comprising a multiple agent system (MAS), which collects the local information of the distribution system controlled by each agent and interacts with the local information collected by each agent, so that voltage-power sensitivity of the distribution system, used for providing the theoretical basis for voltage regulation, is calculated by distributed calculation; and multiple participants, which establish incentive mechanism by DSOs based on the bidding game with imperfect information, and independently decide their own strategies to obtain the voltage regulation subsidy from the DSOs, according to the calculated voltage-power sensitivities, thus provide voltage support for the distribution system in the process of pursuing benefit maximization.
