Sleep Management System

KnightTime is a system designed to monitor and aid the quality of sleep. It is intended to not only help the user quantify their sleep experience but to improve the quality of a significant proportion of life.

Consistent use of KnightTime will allow for a broader, more generalized understanding of sleep habits and associated health effects not easily discovered in a limited laboratory setting.

Team

About Us

From the inception, the team's goal was to design and implement a system that would help improve the quality of a significant portion of life. This project has served as an invaluable experience for each member. It has proved to provide challenges in all aspects of its design, allowing each member the benefit of learning new skills and expand upon his educational foundation in engineering.

FAQ

  • Q. What does it do?

    The system attempts to wake the user during a lighter stage of sleep. This reduces sleep inertia.

  • Q. How does it work?

    KnightTime attempts to monitor sleep cycles through the use of three peripherals.

    The peripherals contain biomedical sensors that transmit data back to the mobile application.

  • Q. How can it improve the quality of my sleep?

    This system intends to combat sleep inertia, which is a feeling of grogginess and sleepiness often encountered when awakening. Awakening during certain sleep stages or at the wrong time relative to one’s circadian rhythm can worsen sleep inertia.

    By identifying the stages of sleep and circadian rhythm of users, this device could help them wake up feeling alert and refreshed.

  • Q. How does the wristband work?

    The wrist peripheral functions as an actigraph unit, which is a non-invasive way of monitoring rest and activity through measuring movement.

    A vibrator was added to act as a non-audible alarm.

  • Q. How does the headband work?

    The headband is designed to function as a sleeping mask that also happens to collect data such as skin temperature and pulse rate.

    A buzzer was added to the headband so that users can have the option of an audible alarm that is closer to their head.

  • Q. How does the basestation work?

    The base station has sensors that collect ambient light, temperature, humidity, and noise.

    A charging module was built into the device so that the peripherals can be charged in a convenient location.

  • Q. Will I have to recharge the battery every day?

    It is recommended that the battery be recharged after each night.

    All of the peripherals were designed to be power efficient and the battery has lasted on a single charge upwards of 3 days.
