#Problem
On UIUC's campus, there is a recurring problem of bikes being stolen on campus. However, it isn't necessarily because they don't have bike locks, it's because the bike locks alone aren't good enough. They're purely mechanical in nature and once they're broken, the robber can ride away with the bike.

#Solution overview 1

(!-- This is one possible solution to the problem --!)

I'm proposing we create a supplement to a bike lock that will prevent the gears from moving unless unlocked. The reason for this is because if a robber breaks a standard bike lock, they'll ride away with the bike. But if we add a fingerprint unlocked bike lock that attaches to the bike's gears, thus immobilizing it. Then, a robber will be significantly less likely to pick up the bike and run with it. If the lock is broken, the lock that is attached to the bikes gears will still be attached and the gears won't move.

The way I measure with a high degree of certainty that a bike is being stolen is by using a built-in accelerometer to detect movement and a gps tracker to alert the user of the bike's location. When the user locks up the bike this activates the accelerometer which will constantly monitor to see if we pass a certain threshold of movement. If this threshold is passed it will trigger the GPS device as well as a suite of anti-theft protection such as lights, and audible beeping, etc.

The reason for this is because if a robber breaks a standard bike lock, they'll ride away with the bike. But if we add a fingerprint unlocked bike lock that attaches to the bike's gears, thus immobilizing it. Then, a robber will be significantly less likely to pick up the bike and run with it. If the lock is broken, the lock that is attached to the bikes gears will still be attached and the gears won't move.

The way I measure with a high degree of certainty that the bike is stolen is by adding a perimeter module that the user can attach to the bike rack. This sets a active customizable perimeter around the bike rack which will monitor if the bike is detected outside the perimeter. If so, it then turns on GPS tracking as well as the suite of anti theft protections.




# Solution Components

## Subsystem 1

All solutions: The software involved in fingerprint locking/unlocking as well as receiving gps location signals from the LoRa module

## Subsystem 2

All solutions: the physical lock attached to the gears

## Subsystem 3

Solution 1: The IMU, the gps tracker, and the anti-theft protection suite sending signals wirelessly through the LoRa module

Solution 2: The perimeter detector, the gps tracker, and the anti-theft protection suite sending/receiving signals wirelessly through the LoRa module


# Criterion For Success

Criterion 1: The physical lock must immobilize the bike forcing the thief to carry the bike in order to move it.

Criterion 2: The fingerprint sensor needs to lock/unlock when a proper fingerprint is scanned

Criterion 3: The gps tracker must accurately (to some degree) give the location of the bike when it is stolen and must be power-efficient (to a reasonable degree)

Criterion 4:
Solution 1 : The accelerometer must correctly detect when a person picks up the bike and runs off with it.
Solution 2: The perimeter module must be able to detect when the bike leaves the range.

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
