摘要: A technology for inhibition of myopia progression adapted to the RPR of the wearer is provided. A spectacle lens and related technology are provided that include a base area that causes a beam that enters through an object-side surface to exit through an eye-side surface and converge on a retina via the eye, and a plurality of defocus areas that each contact the base area and have a characteristic whereby a beam that passes through at least a portion of the defocus area is incident on the retina as a diverging ray, and, in not less than half of the plurality of defocus areas, at least one of a defocus power and a size of each defocus area is set, so as to compensate for a change in retinal spot size due to relative peripheral refraction (RPR) that depends on an eccentricity angle of the eye of the wearer.

摘要: A transparent ultrasound transducer device for multi-mode optical imaging on a target is provided. The device includes a transparent piezoelectric transducer, one or more wires, and an optical lens. The transparent piezoelectric transducer of a first acoustic impedance is configured to receive acoustic waves from the target. The transparent piezoelectric transducer has a first surface and a second surface. The first surface and the second surface are coated with transparent electrically conductive coatings. The optical lens is contacted with and optically coupled to the first surface of the transparent piezoelectric transducer. The optical lens is made of a material with a second acoustic impedance, and the first and second acoustic impedances are substantially similar to minimize an acoustic impedance mismatch such that sensitivity of the device is improved.

摘要: The present disclosure provides a face shield including one or more airstream-deflecting protrusions for deflecting airstream away from the wearer so as to avoid bacteria, virus or any other hazardous materials in the airstream from depositing on the head and/or hair of a wearer. The present disclosure further provides a full face shield including a flexible sheet, and the flexible sheet has a top portion comprising two folding structures located adjacent to lateral edges of the flexible sheet respectively for bending the top portion towards a forehead of a wearer. As the top portion of the full face shield is bent towards a forehead of the wearer through the folding structure, the face, forehead and a large portion of the front skull of the wearer can be protected.

摘要: A multi-level-architecture multi-fiber composite yarn includes a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial direction, and a matrix material included with the yarn, wherein the matrix material has a second anisotropic expansion coefficient that is different from the first anisotropic expansion coefficient in at least one of the axial or radial directions. A method of fabricating a multi-level-architecture multi-fiber composite yarn includes infiltrating a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial directions with a matrix material having a second anisotropic expansion coefficient different from the first anisotropic expansion coefficient in the axial or radial direction.

摘要: The present disclosure provides a cesium tungsten bronze-based self-cleaning nano heat-insulation coating material, and method of preparing the same. Cesium tungsten bronze nanoparticles are prepared by hydrothermal method using WCl6 and CsOH.5H2O as raw materials, PVP as a surfactant and acetic acid as an acid catalyst. TiO2 nanoparticles are prepared from TiCl4. Subsequently ball milling and dispersing of the cesium tungsten bronze nanoparticles, the TiO2 nanoparticles, and a silane coupling agent with water to obtain an aqueous slurry containing cesium tungsten bronze/TiO2 composite particles is performed. The concentration of the aqueous slurry containing cesium tungsten bronze/TiO2 composite particles is adjusted to obtain a self-cleaning nano heat-insulation coating material.
