Abstract: Disclosed are a vehicle warning method and apparatus. The method includes: acquiring real-time information of a vehicle, and determining that an anomaly happens to the vehicle; and sending anomaly information of the vehicle to a nearby terminal by means of short-range wireless communication. In the embodiments of the present disclosure, the short-range wireless communication is adopted, which is convenient and fast, has low costs, is easy to be popularized, and does not depend on 3G/4G or GPS.

Abstract: An optical element includes a transparent layer, outcoupling elements, and a waveguide structure. The outcoupling elements are positioned across the transparent layer. The waveguide structure provides non-visible light to the outcoupling elements and the outcoupling elements outcouple the non-visible light as non-visible illumination light to illuminate an eye region.

Abstract: An example device may include a light source, an optical element, and, optionally, an encapsulant layer. A light beam generated by the light source may be received by the optical element and redirected towards an illumination target, such as an eye of a user. The optical element may include a material, for example, with a refractive index of at least approximately 2 at a wavelength of the light beam. The light source may be a semiconductor light source, such as a light-emitting diode or a laser. The optical element may be supported by an emissive surface of the light source. Refraction at an exit surface of the optical element, and/or within a metamaterial layer, may advantageously modify the beam properties, for example, in relation to illuminating a target. In some examples, the light source and optical element may be integrated into a monolithic light source module.

Abstract: The present invention relates to a method for preparing a carotenoid oil suspension with low viscosity and high fluidity. The method includes the steps of mixing carotenoid crystals with tetrahydrofuran, heating the resulting mixture to a reflux temperature of about 50˜70° C. under stirring, and filtering-the resulting solution to remove fat-soluble fibers. The resulting filtrate is then condensed to dryness, mixed with a ketone solvent, heated to a reflux temperature of about 60˜80° C., and filtered to remove non-soluble phospholipids. The filtrate obtained is condensed to a residue, and absolute alcohol is added to the residue, and then crystallized under stirring at room temperature. The resulting crystals are filtered and dried to-provide carotenoid crystals. The carotenoid crystals are ground and mixed with plant oils to provide a carotenoid oil suspension with low viscosity and high fluidity, which provides easy filling, for example, into capsules.
