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.
Claims17
A method comprising:
- irradiating a product surface of a product with infrared light, the product surface comprising a plurality of stress sensitive hollow, opaque capsules that each enclose a pigment sensitive to infrared light and that are each configured to rupture in response to heat and/or an impact;
- detecting, using a camera, an irreversible activation of the pigment as a color change in response to the infrared light, wherein the activation comprises an activation center and an activation area;
- and
- generating, using a processor, a diagnosis based on the irreversible 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 plurality of stress sensitive, hollow, opaque capsules that each enclose a pigment sensitive to infrared light and that are each configured to rupture in response to heat and/or an impact;
- detecting an irreversible activation of the pigment as a color change in response to the infrared light, wherein the activation comprises an activation center and an activation area;
- and
- generating a diagnosis based on the irreversible activation.
2 more elements
A system comprising:
- an infrared light that irradiates a product surface of a product, the product surface comprising a plurality of stress sensitive, hollow, opaque capsules that each enclose a pigment sensitive to infrared light and that are each configured to rupture in response to heat and/or an impact;
- a camera that captures a surface image of the product surface;
- and
- a processor that detects an irreversible activation of the pigment as a color change in the surface image in response to the infrared light, wherein the activation comprises an activation center and an activation area and that generates a diagnosis based on the irreversible activation.
