#Problem

Many peoples have struggles waking up in the morning. Even with an alarm clock, many people still feel tired or just hit the snooze button and just go back to sleep. There has to be a better way to wake up in the morning.

#Solution Overview

Some new technologies attempt to track a user's sleep cycle to know the optimal time to wake them up with an alarm. Other studies show that using light instead of sound to wake up in the morning makes it easier to wake up, Our plan is to combine these technologies to create a device that will track your sleep cycle and then trigger a lightbulb to turn on. This will allow us to leverage the benefits of both technologies to help people wake up.
We plan to make this device fit on a band/watch which a user will wear and will use a microphone, pulse sensor, and accelerometer to measure the user's noise, heart rate, and movement respectively. These will help us determine what sleep cycle they are in. Additionally. we plan to use a bluetooth module to connect the device with the lgihtbulb and signal the light bulb when to turn on. We expect that this will require users to buy these specific lightbulbs to use the band.

#Solutiion Components

##Band Subsystem

-Will fit on the arm of the user and measure heart rate, noise, and movement.

-Will quickly signal the lightbulb whether to turn on or not

-Will be battery powered

##Light subsystem

-Will be small enough to attach to a standard lightbulb and not impede its connections.

-Will allow the band to communicate to turn on the light

#Criterion for Success

We would consider this project a success if we could build a working prototype with a band that tracks the heart rate, motion, and noise of a user and use that data to correctly interpret whether a user is sleeping and what sleep cycle he's in. The band should also be able to communicate with the lightbulb and the lightbulb will turn on when the band sends the signal.

Featured Project

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.

Hardware

• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
