7 . The alarm clock of claim 1 wherein the display backlight is controlled to decrease brightness when the at least one sensor distinguishes a sleeping human presence.
8 . The alarm clock of claim 1 wherein the display backlight is controlled to increase brightness when the at least one sensor distinguishes a wakeful human presence.
9 . The alarm clock of claim 1 wherein the wake event comprises a prescheduled wake time.
10 . The alarm clock of claim 1 wherein the at least one sensor further distinguishes different sleep levels of sleeping human presence.
11 . The alarm clock of claim 1 wherein illumination level of the display backlight is changed upon the at least one sensor detecting transition between wakeful human presence and sleeping human presence.
12 . The alarm clock of claim 1 wherein the distance of the distance measurement area is settable by a user, and the operation of select and control illumination level of the display backlight comprises select and control the illumination level of the display backlight to be off.
13 . An alarm clock comprising:
a housing;
a display disposed on or in the housing, the display having a backlight;
at least one sensor disposed on or in the housing, the at least one sensor configured to measure distance to a body, the at least one sensor providing sensor signals distinguishing between (a) a wakeful human presence, (b) a sleeping human presence, and (c) no human presence, wherein distinguishing (c) no human presence from (a) a wakeful human presence and/or (b) a sleeping human presence is based on detected change in distance within a distance measurement area in response to an output of the at least one sensor; and
at least one processor disposed in the housing and configured to execute program instructions to perform operations comprising:
control the display to display time,
control a sound transducer to emit an awakening sound in response to the sensor signals; and
select and control illumination level of the backlight based on distinguished no human presence at the time of a wake event.
14 . The alarm clock of claim 13 wherein the distance of the distance measurement area is settable by a user, and the operation of select and control illumination level of the backlight comprises select and control the illumination level of the backlight to be off.
15 . An alarm clock comprising:
a housing;
a display disposed on or in the housing, the display having a backlight;
at least one sensor configured to measure distance to a body, the at least one sensor disposed on or in the housing, the at least one sensor distinguishing between (a) a wakeful human presence, (b) a sleeping human presence, and (c) no human presence, wherein distinguishing (c) no human presence from (a) a wakeful human presence and/or (b) a sleeping human presence is based on detected change in distance within a distance measurement area in response to an output of the at least one sensor; and
processing circuitry disposed in the housing and configured to:
control the display to display a time indication,
control emission of an awakening sound in response to body motion detected by the at least one sensor, and
