Sounds like using an accelerometer to measure vibration and reduce spin speed if vibration is too high might be a good addition to washing machines.

- kw71 10y agoMy made in 2004 LG frontloader has a simpler device for this. A ball bearing rests in the path of an LED light. If it shakes, the ball moves, allowing the light to shine on a phototransistor. The machine will slow down or stop and toss the load around depending on how much trouble it is having.
