Abstract
For generating a diagnosis, a method irradiates a product surface of a product with infrared light, the product surface including a stress sensitive pigment. The method detects an activation of the stress sensitive pigment as a color change at an infrared visible activation location. The method generates a diagnosis based on the activation.
Claims20
A method comprising:
- irradiating a product surface of a product with infrared light, the product surface comprising a stress sensitive pigment;
- detecting an activation of the stress sensitive pigment as a color change at an infrared visible activation location;
- and
- generating a diagnosis based on the activation.

An apparatus comprising:
- a processor executing code stored on a memory to perform:
- irradiating a product surface of a product with infrared light, the product surface comprising a stress sensitive pigment;
- detecting an activation of the stress sensitive pigment as a color change at an infrared visible activation location;
- and
- generating a diagnosis based on the activation.
2 more elements
A system comprising:
- an infrared light that irradiates a product surface of a product, the product surface comprising a stress sensitive pigment;
- a camera that captures a surface image of the product surface;
- and
- a processor that detects an activation of the stress sensitive pigment as a color change at an infrared visible activation location in the surface image and that generates a diagnosis based on the activation.
