Sleep state analysis machine

This is the latest sleep state analyzer on the planet, and unlike previous products, you don't need to wear it on your wrist or buckle it to your head. It is equipped with sound and image sensors that record and analyze all kinds of information during your sleep, such as snoring, farting, turning over, grinding your teeth, talking in your sleep, etc. This data is then used to analyze whether you are in light or moderate sleep or deep sleep, and to show how long each sleep stage lasts.
