See full text

A rain sensor in a vehicle includes a transmitter to implement a pseudorandom modulation of a timing of emission of infrared transmissions toward a windshield of the vehicle. The rain sensor also includes a receiver to be active for only a specified period of time following each emission of the infrared transmissions and to receive a reflection based on the infrared transmission encountering any substance on the windshield.
