What is an Alarm Clock
An alarm clock is a clock that is designed to alert an individual or group of individuals at a specified time period. The primary function of such clocks is to awaken people from their night’s sleep or short naps. Sometimes it’s used for other reminders as well. For alarms, most of the clocks use sound while some use light or vibration. Some clocks have sensors to identify when a person is in a light stage of sleep, in order to prevent waking someone who is deeply asleep, which causes tiredness, even if the person has had enough sleep. Such clocks also have a push-button or handle to stop the sound or light. But, most clocks automatically stops the alarm if left unattended long enough. These alarm clocks are also found on mobile phones, watches, & computers.
The very first American alarm clock was designed by Levi Hutchins, of New Hampshire, in the year 1787. The device which he made was only for himself which had the ability to rang only at 4 AM, in order to wake him for his job. He didn’t even have to be at work so early but it was simply his firm rule to wake before the sunrise. Later, the French inventor Antoine Redier was the first to patent a flexible mechanical alarm clock, in the year 1847.
