Peaceful awakenings: taking the "alarm" out of the alarm clock.
The quality of my daily awakening ritual changed dramatically a few months ago when I was exposed to the Timex Nature Sounds alarm clock. Prior to this, it had never occurred to me to use something other than the traditional buzzer-type alarm clock that I had had since 1986 because “it still worked.” While this was true, it worked by emitting a loud obnoxious sound that stimulated a fight or fl...
متن کاملDesign Principles of a Genetic Alarm Clock
Turning genes on and off is a mechanism by which cells and tissues make phenotypic decisions. Gene network motifs capable of supporting two or more steady states and thereby providing cells with a plurality of possible phenotypes are referred to as genetic switches. Modeled on the bases of naturally occurring genetic networks, synthetic biologists have successfully constructed artificial switch...

متن کاملAdaptive Alarm Clock Using Movement Detection to Differentiate Sleep Phases
Waking up can be very troubling. In many cases, being awoken by the alarm clock during a period of deep sleep causes a person to not feel fully rested after waking up. This paper describes how an adaptive alarm clock was developed addressing this problem. The alarm clock predetermines in what state the sleeper will be at the instant of supposed alarm-firing, and adjusts that instant to a more f...
متن کاملSleep: The Sound of a Local Alarm Clock
Besides the master clock located in the suprachiasmatic nucleus (SCN) of the brain, additional clocks are distributed across the central nervous system and the body. The role of these 'secondary' clocks remains unclear. A new study shows that the lack of an internal clock in histamine neurons profoundly perturbs sleep.
