  • Patent number: 11906124
    Abstract: A system may have lights. The lights may emit visible and infrared light. Infrared light may be used to illuminate objects that are monitored using infrared image sensors or other infrared sensors. Visible light may be used to illuminate objects that are viewed by users and which may be monitored using sensors. The lights may be adjustable. An adjustable light may have a light source that contains an infrared light-emitting device such as an infrared light-emitting diode and a visible light-emitting device such as a visible light-emitting diode. A reflector may reflect light from the light source towards a lens. An adjustable light-blocking device may be located between the reflector and the lens. The light-blocking device may allow infrared light to pass unimpeded while adjusting visible light passing to the lens.

  • Publication number: 20230395015
    Abstract: A display may have a display panel with an array of pixels formed from light-emitting diodes. Optical films that help collimate and homogenize light from the light-emitting diode pixels may overlap the light-emitting diodes. A transparent cover may overlap the display. The transparent cover may have an outer surface and an opposing inner surface, which may have areas of compound surface curvature. Louvers that serve to reduce off-axis solar light reflections while allowing light from the display panel to be emitted may be formed from molded polymer supported by a transparent cover layer in the cover. A diffuser may be formed by embedding light-scattering particles in a polymer layer covering the louvers and/or by forming light-scattering surface structures such as ridges and/or other texture on the surface of the polymer layer. Electrically adjustable light modulator layers and electrically adjustable louvers may be used in the display.

  • Publication number: 20230394990
    Abstract: Disclosed is a simulation device for electron-excited atmospheric radiation. An electron gun cavity is connected with a front end of a gas cavity. An electron gun is used for emitting electrons and injecting the electrons into the gas cavity. The electrons collide with gas molecules in the gas cavity to ionize and excite the gas molecules. According to the miniaturized simulation device for electron-excited atmospheric radiation, the device can realize an ionization excitation experiment of high-energy electrons on neutral gas and generate a series of optical radiation phenomena in special scenes. In addition, with the aid of optical observation equipment, optical radiation signals of ionized neutral gas can be obtained, so that radiation laws under different incident electron energies, different radiation intensities and different atmospheric components can be further obtained.
