摘要： Example embodiments described herein involve reducing the formation of ice on external modules by incorporating a heater within the module. The system may include a microphone module for an autonomous vehicle. The microphone module may include a housing and a microphone inside an opening of the housing. The system may further include a cover abutting the opening of the housing. The cover may enclose the microphone within the housing and seal the opening of the housing. The system may also include a heater adjacent to the opening of the housing and configured to prevent ice from forming over the opening. The heater may at least partially surround the opening.

摘要： 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.
