Figure 3From: Sleep/wake estimation using only anterior tibialis electromyography data An example of y k , threshold T m and HEMG m in subject #1. (a) yk signals from the 392th epoch to the 397th epoch; T395 was about 60. Bold lines indicate the yk signals of each epoch, and the dashed line indicates the threshold Tm. (b) Enlarged figure of epoch 395 in panel (a). In this case, HEMG395 was six.Back to article page
