	Many times GPS devices can not be used to locate a person in a big crowd. They are not accurate enough to tell you exactly where a person is within close distances,and sometimes the signal is unreliable.The friend finder armband aims to fill this void in the market by creating an intuitive tool to easily find others which works where GPS does not. Our product would be useful in a myriad of situations including concerts, malls, and any other events where large gatherings of people make getting separated easy. Our goal is to develop a compact armband that will allow the users to easily locate each other in any situation. The armbands will use a system of antennas to locate each other. There will be increasing vibration with increasing proximity. Moreover, the armbands will have LED's to point the user in the right direction.

# Automatic Water Bottle Filler

Team Members:

- Jakub Migus (jmigus2)

# Problem

In normal liquid dispensing and water bottle filling systems, the process requires the user’s attention and constant manual activation of the device. This may require the holding of a button, the action of pushing the bottle against a sensor for a specific amount of time, or holding the bottle in front of a sensor until it is full. If the user gets distracted or is unable to provide that attention (blindness or lack of motor function), liquid may spill or the bottle may not be filled enough.

# Solution

Our goal with this project is to make an automatic water bottle filling station. Our device senses when a water bottle is placed underneath it, begins filling the bottle with water once a start button is pressed, determines when the bottle is full and shuts off automatically. After placing the bottle on a platform and pressing a button, the user can walk away knowing their bottle will be filled accurately.

# Solution Components

## Sensing Component

This subsystem utilizes multiple sensors including an ultrasonic sensor to measure the water level and a light-based sensor to determine the height of the bottle.

## Control

This subsystem connects the sensors to the water system. It receives data from the sensors, compares the water level height to the height of the water bottle, then decides to either begin, continue, or stop dispensing water.

## Display/Interface System

An LCD display will show instructions for the user and will display simple messages. A few push buttons will be included for manual filling and selection of desired amount of liquid (ex. Half bottle, full bottle)

## Water System

This subsystem utilizes a water tank attached to a pump and tubing, which transport water to the dispenser.

# Criterion for Success

The device…

- detects a water bottle and accurately measures the height

- monitors the water level in the bottle

- stops filling when a desired water level is reached

If there is no bottle/ the bottle is removed, the device stops filling water.
