Abstract

The alarm clock is a device designed to wake a person or several people up at a specific time. The basic structure of the conventional alarm clock is the combination of a time-keeping mechanism (mechanical, electromechanical or electronic) and a sound source (i.e. bell, buzzer, beeper, or a loudspeaker). The principle of operation is to automatically activate the sound at a predetermined time, for the purpose of waking a person or people. The activation time is user-settable. In some clocks, the user may also have the ability to select the type of sound (e.g.- beeps or radio station) and the volume.

Personal Alarm Clock with Wireless Earpiece

By Haim Friedlander and Gadi Shirazi

 

1. Introduction – the problem

The alarm clock is a device designed to wake a person or several people up at a specific time. The basic structure of the conventional alarm clock is the combination of a time-keeping mechanism (mechanical, electromechanical or electronic) and a sound source (i.e. bell, buzzer, beeper, or a loudspeaker). The principle of operation is to automatically activate the sound at a predetermined time, for the purpose of waking a person or people. The activation time is user-settable. In some clocks, the user may also have the ability to select the type of sound (e.g.- beeps or radio station) and the volume.

There are two common problems with alarm clocks:

(a) They sometimes fail to wake the right person. This is usually due to the fact that the sound level (either fixed or set by the user) may not be sufficient to wake someone from a deep sleep. Another common situation is blockage of the person’s hearing by a pillow, covers, etc.

(b) They tend to wake the wrong people. This is because the alarm clock is not selective – it could wake anyone within hearing range. Sometimes this is an advantage, but usually it is not desired. For example, if two people sleeping in the same room need to wake up at different times, the one who needs to wake up first sets the clock for himself/herself, and after waking up he/she resets it for the second person. Most likely, however, both of the people will wake up when the alarm clock rings, or perhaps the wrong person will wake up first.

2. Closest known technology

The various alarm clocks available today provide a wide range of different wake-up signals, including voice, music, simulations of natural sounds, etc. But they all suffer from the same basic drawback – they are not selective, and they cannot insure waking the correct person without waking others.

3. The solution – “Wireless Alarm Clock”

The key to solving the problems described above is to provide a selective signalling mechanism, so that only one person will be awakened by the alarm clock. This can be accomplished by means of a “Wireless Alarm Clock”, which will be described below.

3.1 General Description

The clock will consist of two parts: (1) a base unit, and (2) a wireless personal waking device. The base unit will contain the timekeeping mechanism and a low-power wireless transmitter. The wireless personal waking device will contain a battery and a miniature wireless receiver, and will have some means of stimulating the person wearing it without disturbing anyone else. This concept is illustrated in Figure 1.

3.2 Wireless Personal Waking Device- Description

Two examples of personal waking devices are: (a) wireless earpiece, and (b) wireless bracelet. These wireless personal waking devices will be described below:

The wireless earpiece will contain a micro-miniature radio-frequency receiver, a battery and an earphone. ...
