Silly Control Idea: Splash free…

Wave dampening

Bob-on-a-string array that would be controlled to dampen (and possibly detect) waves in a liquid, such as a pool or shipping container. If placed in the corner of a pool, the bob array would absorb the wave’s energy.

“No Spill” Coffee Cup

Fluid would sit in a portion of a gimbal. A few vertical capacitive sensor strips would be placed around the cup to detect the shifting of water. Gimbal rotation would be controlled to maintain a flat water surface relative to the bottom of the cup.
