Scientific studies on sleep having shown that sleep stage at awakening is an important factor in amplifying sleep inertia. Alarm clocks involving sleep stage monitoring appeared on the market in 2005. The alarm clocks use sensing technologies such as EEG electrodes and accelerometers to wake people from sleep. Dawn simulators are another technology meant to mediate these effects.

When the mains' input moves to the transformer, the component helps to change the input voltage to a 12V AC signal. When this happens, the diode (D1) and capacitor (C1) swing into action by changing the AC voltage to DC. Then, it supplies the IC1's Vdd (Pin 20). dallas fort worth airport skylink
