Major problem that the concept solvesMajor problem that the concept solves• Parents need not to get out of bed to wake kids up• Alarm output can be adjusted to very high, forcing children

to wake up in case they try to ignore it.

Possible uses/applications of the system• As a one-alarm clock for the whole house, each room can

have a different time that the alarm will go off in that room.• In ships for alerting crew (in different decks of danger) or

just to wake them up as well.• By managers as a means to call employees to their offices.
