Sleep disorders are a major health problem affecting more than 50 million people in the US alone. Sleep Apnea (SA) is by far the most common of these disorders, causing excessive sleepiness and diminished cognitive functions. Monitoring the respiratory effort is essential for SA detection. Conventional methods are limited to measuring only respiratory effort, and methods based on Inertial Measuring...
It is necessary to adopt effective data fusion method to improve the data efficiency and the accuracy of attitude determination, due to the sensors of low accuracy and low power dissipation is often used in attitude determination with the limitation of scientific research funding and power restriction. A new micro satellite attitude determination algorithm based on fusing-feedback federal filtering...
This paper presents an original multi-sensor system for 3D orientation determination based on only 4 MEMS sensors. MEMS sensors are manufactured on a cheap standard technology from NXP Semiconductors using TMAH front side wet etching with no additional masking step. This very low cost manufacturing process makes the system suitable for various consumer applications. Electronic architecture for signal...
