Abstract
A wake-up alarm is set to ring in some time interval. One or more physical characteristics of the sleeping subject, including brain wave activity, pulse rate, REM activity, muscle tension, body temperature, hearing acuity, positional changes and the like are monitored to determine whether the subject is in a deep or shallow-sleep phase. If the subject is in the deep-sleep phase throughout the alarm time interval, the alarm is inhibited until the end of the alarm interval. The inhibiting of the alarm ends as soon as the subject goes into a shallow-sleep phase.
