  • Optical moisture sensor for a window or windshield
    Patent number: 4652745
    Abstract: A windshield moisture detector has two identical, symmetrically positioned prisms with an elongated body between an integral reflector and light transducer cavity. One light transducer cavity contains a light source and the other a light detector. The reflectors are angled so that when the moisture detector is partially in contact with the windshield, light can travel between the two reflectors through a light path in the window. The magnitude of light transmitted through the windshield is indicative of moisture on the windshield.
