TITLE MUSCLE TONE DETECTOR FOR SLEEP ANALYSIS INVENTORS Roger Broughton Bernardo Da Costa ABSTRACT OF THE DISCLOSURE The muscle tone detector periodically samples the electromyo- gram (EMG) signal to determine the level of muscle activity for sleep analysis. The signal is sampled periodically for nearly two second periods, the amplitude of the components of the sample that have a real- time frequency greater than 22 Hz, is then monitored and categorized in one of five levels, i.e. below 12 µV, from 12-29 µV, from 29-45 µV, from 45-57 µV and above 57 µV. The detector output is a series of one to five pulses for each sample period.
