Abstract
Methodology and corresponding apparatus pertains to sleep disruption monitoring, including use of a wireless signal-based monitoring system leveraging millimeter-wave technology. A software-only sleep disruption monitoring solution can be based on millimeter-wave (mmWave) wireless-based solutions which leverage cross-correlation between successive mmWave reflected signals and a Hidden Markov Model (HMM) to identify respective sleep (rest) and disruptions (toss-turn) periods. A toss-turn detector module can identify sudden movements during sleep from mmWave wireless signals and classify the sleeping period into the two states: Rest or toss-turn. Whenever mmWave transceivers (such as included in 5G-and-beyond devices) are implemented as access points, in mass privacy non-invasive sleep disruption monitoring can be provided for consumers at home.
