- You may have noticed that on some take-away drink cup lids, there are small domes that can be “popped down” to indicate what sort of beverage is in the cup.
- Working with colleagues from the University of Tennessee, scientists at Indiana’s Purdue University have developed a proof-of-concept model in which a grid of cup-lid-like polyurethane domes is mounted on the top surface of a section of aircraft wing.
- Making things simpler is the fact that because each dome is either up or down, the data they provide is like the 1s and 0s used in binary computing.
Drink cup lids inspire a system that could keep drones flying safely
