Description

The Sunrise Alarm Clock is a device designed to be more effective than standard alarm clocks and more pleasant than specialty devices in waking the hearing impaired. This is accomplished with the inclusion of visual, physical, and audio alarms. The visual alarm stimulus is created by manipulating the light output of a bedside lamp to mimic the sunrise. This is achieved by varying the duty cycle of a pulse width modulated signal supplied through a standard three-prong receptacle located on the side of the alarm clock. Physical alarms are in the form of wristbands containing vibrating motors. Finally, audio alarms are provided with both volume and pitch control to match the user’s specific needs. The entire system is designed with two users in mind by providing two independently controlled receptacles, wristbands, and audio systems. At the conclusion of development, a nearly fully functional prototype has been produced. The prototype’s audio and physical alarm system along with one visual alarm are fully functional. Shortcomings include poor timekeeping accuracy and problems clearly displaying the time. Even so, this development in sleep technology is capable of performing its task and waking its user with all three alarm systems.
