A conventional thermal camera is like a thermometer that slowly heats up and cools down. It shows where heat is well, but it can't keep up with fast motion. The new sensor works differently: it counts individual quanta of heat, like a droplet counter during rain.

Active noise cancellation creates 'anti-sound' to neutralize noise. But ordinary systems are blind: they don't know where the sound is coming from. In rooms with an echo, it's like boxing with a blindfold on — you're canceling blindly.
