A recent post published on the NeoGAF forum sheds light on a possible patent from Nintendo Co, Ltd (TYO:7974) (OTCMKTS:NTDOY). The patent describes a sleep-tracking device which looks similar to an alarm clock.

Nintendo’s late CEO, Satoru Iwata, shared a photo of the device which reportedly used microwave transmission sensors to obtain data and recommend sleep habits. The device was dubbed the S+ and could include a bedside monitor, smartphone app and web app. It could also come packed with other sensors for measuring pulse rate, temperature and biometrics.
