The protective device has a movable part and a fixed part. The protective casing forms a cavity that accommodates an optical sensor that includes an optical surface. Additionally, the protective casing freely rotates about an axis and includes an optical element that faces the optical surface of the optical sensor. The motor rotates the protective casing at speeds allowing the optical element to be cleaned by a centrifugal effect. The pressure balancing system includes an air vent orifice allowing fluid communication between the inside and the outside of the protective device. The air vent orifice is produced in the fixed part of the protective device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for protecting an optical sensor of a driving assistance system for a motor vehicle","description":"A device for protecting an optical sensor of a driver assistance system for a motor vehicle includes a protective casing, a motor, and a pressure balancing system.
