If you engage in a game of word association, chances are when you hear the term Formula 1, responses will be terms associated with speed: race car, acceleration, fast, momentum, velocity...

But as much as Formula 1 is about speed, it’s also about controlling and channeling that…

Painter Bob Ross taught us that “happy accidents” can make beautiful art. Happy accidents also happen in science when experiments take research in unexpected directions. One dramatic example is Sir Alexander Fleming’s accidental discovery of penicillin.

Not all unexpected…

Four years ago, National Institute of Standards and Technology (NIST) researcher Cyrus Daugherty developed an algorithm to virtually unroll the tightly wrapped layers of a cylindrical lithium-ion battery. Daugherty’s software transformed X-ray images of the battery, taken at different angles,…

Highly reflective metallic surfaces are among the most challenging inspection targets in machine vision. Reflections obscure details; defects often become visible only from certain angles, and the quality of manual visual inspections fluctuates throughout the workday.

The Austrian…

A measurement isn’t only a number. It’s a number obtained by an instrument in a physical state.

That distinction becomes critical when the instrument moves, bends, conforms to a surface, or relies on software to correct its own geometry. A rigid gauge can often treat its working…
