This paper presents the validation of a noninvasive sleep monitoring device and sleep quality evaluation. The system is based on an array of pressure sensors positioned on the bed that can measure relevant parameters to estimate sleep quality. This device can measure time in bed (TB), body movements (BM), the thorax expansion, periods out of bed (POB) and apnea events. We compare the results of the...
The mining industry is constantly looking to improve the safety of mine operators and their productivity. The sleep quality of mine workers is an important issue related to both goals. Miners are usually exposed to hard working shifts in a hostile environment, which can lead to deficient rest between shifts. Inadequate sleep is related to fatigue and higher risk of accidents. Sleep quality is traditionally...
The mining industry is constantly looking for improvements to the safety of the mine operators and productivity. Sleep quality of mine workers is an important issue related to both goals. Miners are usually exposed to hard working shifts in a hostile environment, without specialized medical supervision. Deficient rest during shifts is related to fatigue and risk of accidents. Sleep quality is usually...
This project implements a non-invasive sleep monitoring system using a bed pressure sensor array. The system detects changes in the contact pressure between a subject and the bed and is able to automatically select the sensor with the best respiratory signal, determine the respiratory rate (RR), count number of sleep apneas and count body position changes through the night. The respiratory signal...
