Patent number: 11733126Abstract: A tire defect detection system for detecting defects in a tire. The system includes at least one infrared camera, a pneumatic source and a computing device. The pneumatic source inflates the tire to a predetermined pressure. After inflation, the infrared camera captures a reference frame of a section of the tire. A period of time after capturing the reference frame, the infrared camera captures a subsequent frame. The subsequent frame is compared to the reference frame to detect a portion of the section of the tire that has a lower temperature. The lower temperature is caused by an escape of air from the tire through a defect. The escaping air cools the area of the tire around the defect, so a decrease in temperature indicates the defect.Type: GrantFiled: July 7, 2021Date of Patent: August 22, 2023Assignee: Paul E. Hawkinson CompanyInventors: Gary William Box, Brian B. Brasch, Anthony S. Rike
