Abstract: Example embodiments described herein involve a system for testing a light-emitting module. The light-emitting module may include a mounting platform configured to hold a light-emitting module for a camera. The mounting platform may also be configured to rotate. The system may further include a housing holding a plurality of photodiodes arranged in an array over at least a 90 degree arc of a hemisphere. The system may also include a controller configured to control the photodiodes and the rotation of the mounting platform.

Abstract: A system includes multiple microphone arrays positioned at different locations on a roof of an autonomous vehicle. Each microphone array includes two or more microphones. Internal clocks of each microphone array are synchronized by a processor and used to generate timestamps indicating when microphones capture a sound. Based on the timestamps, the processor is configured to localize a source of the sound.

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.
