Abstract: A camera module includes a housing with an opening and a portion that surrounds the opening, wherein the portion of the housing is transparent to near infrared (NIR) light. A fisheye lens is disposed within the opening such that a portion of the fisheye lens protrudes through the opening. An image sensor is disposed within the housing and optically coupled to the fisheye lens. The image sensor is sensitive to visible light and NIR light. A plurality of NIR light emitters is disposed within the housing. The NIR light emitters are configured to emit NIR light through the NIR-transparent portion of the housing. The NIR-transparent portion of the housing may include a light-diffusing structure, such as a pattern of microlenses formed on an inner surface of the NIR-transparent portion of the housing, to spread out the NIR light emitted by the NIR light emitters.

Abstract: The technology provides a camera module cover that prevents infrared light from leaking into the lens of an adjacent camera. The camera module cover can be used with in-vehicle environments, such as the passenger area and truck, as well as other indoor locations and places where infrared illumination is co-located with an optical camera system. An infrared illuminator unit is positioned adjacent to the camera, for instance in such a way that infrared light is evenly distributed or diffused around the camera lens. The camera module cover has a surface that includes an infrared-transparent material to promote even distribution of the infrared light. To avoid leakage into the camera lens, an infrared-opaque or otherwise blocking material is disposed within the cover so as to be between the infrared illuminator unit and the camera lens. The infrared-transparent and infrared-blocking materials may be formed as a single part via double injection molding.

Abstract: Example embodiments described herein involve a structural support for shielding from electromagnetic interference between components in a display system and for discharging electrostatic charges. The display system may be implemented in an autonomous vehicle. A display system may include a screen, a printed circuit board (PCB), and a cast housing comprising a metal. At least the screen and the PCB may be grounded to the cast housing. The cast housing may shield at least the screen and the PCB from electromagnetic interference. A grounding cable may be connected to the cast housing via a self-tapping screw, the grounding cable extending to an electrical ground.
