  • Publication number: 20240418566
    Abstract: The present invention provides an ambient light sensor with ultraviolet light detection function, which is adopted to receive external light for sensing. The ambient light sensor comprises a visible light sensing chip and a wavelength conversion layer. The visible light sensing chip is used for sensing light corresponding to the response band of visible light, and the visible light sensing chip includes a light receiving surface. The wavelength conversion layer is used to convert light corresponding to a specific ultraviolet light band of the external light into light corresponding to a response band of visible light, and the wavelength conversion layer covers at least a part of the light receiving surface.

  • Patent number: 10833417
    Abstract: Systems and methods which provide filtering dielectric resonator antenna (FDRA) configurations implementing radiation cancellation are disclosed. Embodiments of a FDRA provide implementations of dielectric resonator antennas (DRAs) which are configured with a loop feed structure facilitates radiation cancellation to provide radiation nulls at frequencies outside of a desired passband to thereby implement radiation cancellation for filtering functionality of the FDRA. FDRAs of embodiments may be variously polarized, such as to provide linear polarization or circular polarization.
