  • Wheel integrity monitoring system
    Patent number: 10866195
    Abstract: A wheel integrity monitoring system for monitoring the integrity of a railcar wheel in an automated manner while the railcar is in operation (i.e., traveling) and comprising a light source that projects light onto the wheel and a light detector that detects the light reflected by the wheel. The wheel integrity monitoring system is configured to analyze the reflected light to determine if the wheel is defective.
