Unobtrusive online monitoring of sleep at home [PDF]

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
We describe an online sleep monitoring service, based on unobtrusive ballistocardiography (BCG) measurement in an ordinary bed. The novelty of the system is that the sleep tracking web application is based on measurements from a fully unobtrusive sensor.

Overnight consolidation aids the transfer of statistical knowledge from the medial temporal lobe to the striatum [PDF]

, 2012
Sleep is important for abstraction of the underlying principles (or gist) which bind together conceptually related stimuli, but little is known about the neural correlates of this process.

Development of a non-contact sleep monitoring system for children

Frontiers in Digital Health, 2022
Daily monitoring is important, even for healthy children, because sleep plays a critical role in their development and growth. Polysomnography is necessary for sleep monitoring. However, measuring sleep requires specialized equipment and knowledge and is

Thermal Vision for Sleep Apnea Monitoring [PDF]

, 2009
The present paper proposes a novel methodology to monitor sleep apnea through thermal imaging. First, the nostril region is segmented and it is tracked over time via a network of cooperating probabilistic trackers. Then, the mean thermal signal of the nostril region, carrying the breathing information, is analyzed through wavelet decomposition.

Blood Pressure Non-Dipping and Obstructive Sleep Apnea Syndrome: A Meta-Analysis [PDF]

, 2019
AIM: We examined the reduced blood pressure (BP) nocturnal fall in patients with obstructive sleep apnea (OSA) by a meta-analysis including studies that provided data on prevalence rates of non-dipping (ND) pattern during 24-h ambulatory blood ...

A Sensing Platform to Monitor Sleep Efficiency

, 2022
Sleep plays a fundamental role in the human life. Sleep research is mainly focused on the understanding of the sleep patterns, stages and duration. An accurate sleep monitoring can detect early signs of sleep deprivation and insomnia consequentially implementing mechanisms for preventing and overcoming these problems.
