Patent number: 11667799Abstract: A cooperative vehicle-highway communication system allows vehicles and pedestrians to determine their location by sensing selected coatings on roadways, sidewalks, and other paved surfaces in both indoor and outdoor environments. The systems recognize intelligent materials under sensors to determine geo-location. The intelligent materials are incorporated into paints on the roadway surface to mark key locations. Additionally, vehicles recognize highway paint/markings and signs with intelligent paint that provide specialized message content to support driver information and control applications. The intelligent paint materials include a coating that absorbs light while converting the absorbed light to electromagnetic energy. This electromagnetic energy is read by sensors to recognize the materials.Type: GrantFiled: January 13, 2021Date of Patent: June 6, 2023Assignee: INTELLIGENT MATERIAL SOLUTIONS, INC.Inventors: Howard Y. Bell, Joshua E. Collins, Robert A. Ferlis, Kunik Lee
