The aim of this study is to develop and evaluate an algorithm to help in the diagnosis of the obstructive sleep apnea syndrome (OSAS). Arterial oxygen saturation (SaO2) signals from nocturnal pulse oximetry were used to identify OSAS patients. A total of 149 SaO2 recordings from subjects suspected of OSAS were available. The initial population was divided into a training set (74 subjects) and a test...
A classification algorithm is developed to translate facial movements into five cursor actions: i) left, ii) right, iii) up, iv) down, and v) left-click. The algorithm utilizes the unique spectral characteristics exhibited by electromyogram (EMG) signals obtained from different muscles in the face to assist in the classification process. A previous three-electrode, EMG-based system was utilized in...
