  • Publication number: 20220344037
    Abstract: The present invention relates to a nursing information module automation system and method. The method includes steps of detecting a nursing record inputted by a user; transmitting the nursing record to a nursing information module automation natural language processing model to perform a focus prediction, so as to automatically predict at least one nursing focus based on the nursing record; and recommending at least one recommended module in accordance with the at least one nursing focus by the nursing information module automation natural language processing model.

  • Patent number: 7864449
    Abstract: A negative refraction photonic crystal lens is provided. The negative refraction photonic crystal lens includes a substrate and a plurality of voids periodically distributed in the substrate. The voids are configured extending along a direction longitudinally perpendicular with an incident direction of a light having a specific wavelength. By suitably selecting a refractive index of the substrate, a radius of the voids, and a lattice parameter of the voids, the negative refraction photonic crystal lens presents a negative refraction characteristic with respect to the specific wavelength, in that the light incident from one side of the substrate can be focused at the other side of the substrate, thus configuring an optical lens. The optical lens is adapted for not only achieving an optimal sub-wavelength focusing performance, but also further improving the imaging resolution of the negative refraction photonic crystal lens by employing an anisotropic material for preparing the substrate.
