# Problem

Many elderly persons may live in elderly homes or retirement homes and have many health related problems. It might be difficult for the staff to be able to keep track of the health of all the individuals and ensure that they are able to keep performing their daily routine without additional assistance. It might be hard for them to track problems immediately due to difficulty communicating and the caretakers would not know when their health is deteriorating until their condition becomes very serious. In elderly homes or retirement centers, it might be hard to keep track of a number of elderly patients, especially when the technology like Apple Watches or Fitbits are not intuitive for older people or customized to their needs and are too expensive. It is not feasible to ask the staff to monitor each individualized fitbit and track it separately without a more centralized system.

# Solution

Describe your design at a high-level, how it solves the problem, and introduce the subsystems of your project.

In this situation, a cost effective device that keeps track of various health data such as heart rate, temperature, step counts, gps to track where they are, sleep tracking and their daily habits like how many times they visit the bathroom and the duration of time they are in the bathroom, and if there are any irregularities can be a good indicator of their health. Our web application would allow the elderly home caretakers to monitor multiple elderly people at once. A notification would be sent when there is an irregular/ critical heart rate/ breathing activity for a particular person. We could also potentially store past health data points to a database and monitor for any irregularities, or this can be used by doctors during checkups.

The subsystems are the health sensors, emitter, WIFI enabled microcontroller, and our web application.

# Solution Components

## Health Sensors

We would have different sensors to measure the different health parameters and indicators. These sensors will be placed either on some kind of sleeve on their wrist (for heart rate measuring) or a belt on the stomach to get direct measurements. We are planning on implementing the following sensors:
Temperature - NTC Thermistor by TE Connectivity
Heart Rate and BPM - PulseSensor
Sleep Tracking Sensor and Step Count : Accelerometer by BOSCH BMA400
GPS - PA1616D
Infrared Detector - to detect infrared radiation by the specific device when it receives a signal from the emitter system

Explain what the subsystem does. Explicitly list what sensors/components you will use in this subsystem. Include part numbers.

## Emitter Subsystem
This subsystem allows us to keep track of the number of times the bathroom is used and the number of times the bathroom is used. The sleeve would have an infrared detector and the bathroom facility would have two sensors - one at the entrance outside and one inside the bathroom once they enter. Depending on which sensor is detected first, we can see if they are entering or leaving the bathroom and this can help us keep track of the number of times they used it and the length of duration that they used it.

## WIFI enabled microcontroller
The various health sensors would send the health data over to the microcontroller. The microcontroller would then send these data to our database using HTTPs requests to our backend via the WIFI module. We assume that our devices would be used in elderly homes or retirement homes, so there would be WIFI available.

## Web Application
This web application would enable the staff to monitor multiple elderly at once in one page. This application would be a full - stack web application, using MERN stack (MongoDB, Express, React, Node). We would design the database schema, front end, and backend. If there is an irregular activity, we would send out an alert. This page would be updated periodically close to real-time.

# Criterion For Success

Describe high-level goals that your project needs to achieve to be effective. These goals need to be clearly testable and not subjective.

- Send out an alert on the web applications when the heart rate is below a certain threshold or temperature is not within acceptable range for healthy person
- Able to measure the data from all the sensors and send it to the microcontroller and store in the database

Sometimes bikers might not which gear is the optimal one to select. Bicycle changes gears by pulling or releasing a steel cable mechanically. We could potentially automate gear changing by hooking up a servo motor to the gear cable. We could calculate the optimal gear under current condition by using several sensors: two hall effect sensors, one sensing cadence from the paddle and the other one sensing the overall speed from the wheel, we could also use pressure sensors on the paddle to determine how hard the biker is paddling. With these sensors, it would be sufficient enough for use detect different terrains since the biker tend to go slower and pedal slower for uphill or go faster and pedal faster for downhill. With all these information from the sensors, we could definitely find out the optimal gear electronically. We plan to take care of the shifting of rear derailleur, if we have more time we may consider modifying the front as well.

Besides shifting automatically, we plan to add a manual mode to our project as well. With manual mode activated, the rider could override the automatic system and select the gear on its own.

We found out another group did electronic bicycle shifting in Spring 2016, but they didn't have a automatic function and didn't have the sensor set-up like ours. Commercially, both SRAM and SHIMANO have electronic shifting products, but these products integrate the servo motor inside the derailleurs, and they have a price tag over $1000. Only professionals or rich enthusiasts can have a hand on them. As our system could potentially serve as an add-on device to all bicycles with gears, it would be much cheaper.
