# Problem
Have you ever seen a plant in nature or an animal in the wild that piqued your interest, but you didn’t have an efficient way of researching what it was? Repeatedly searching online to identify the subject can be a lengthy and tedious task, and this is the problem we seek to address. Our solution is meant to enlighten our user of unknown plants, animals, or objects in any setting they are observing.

# Solution
Our project idea stems from the surge of AR prototype glasses being introduced over the past year. We are planning to create our own glasses but in contrast to those on the market, ours will focus on the audio experience of the user. These glasses will have the explicit capability of capturing images of objects and relaying this information to an application that will process these images in the backend. The application will then send an explanation of the object back to an audio device on the glasses (either a speaker or bone-conducting device). The glasses will essentially work as a digital tour guide, with the explanation of the object being auditory rather than visual. The use case we have decided to tackle is a botanical tour guide, but the purpose is to create a platform that other applications can utilize for their objectives.

The subsystems we have broken down the device into are power, peripheral, communication, physical, and application. They are divided such that each subsystem has a designated purpose working towards the goal of full functionality.

# Solution Components

## Power System
The power system consists of the battery powering the device and the supporting charging circuit to replenish the battery once out of power. Some candidates for batteries are PCIFR18650-1500 from ZEUS Battery and ASR00011 from TinyCircuits.

## Peripheral System
The peripheral system focuses on the aspects of the glasses that interact with the outside world. This includes the camera, microphone, speaker, and interact button. These external components will interface with the microcontroller, provide crucial information to the application, and play audio to the user. For the moment we have the following components for each peripheral:
Camera: ESP32-CAM (Comes with development board and camera)
Microphone: CMA-4544PF-W
Speaker: ADS01008MR-LW100-R
Interact Button: B3U-1100P

## Communication System
The communication system consists of a microcontroller and Bluetooth Low Energy interface. This subsystem should create an interface that can be used by applications connected through Bluetooth. This interface allows for all the sensor data to be collected, processed, and sent to the application when requested. The component we plan to use for this system is the ESP32-WROOM-DA-N8 which contains an ESP32 microcontroller with a built-in PCB antenna for Bluetooth.

## Physical System
The physical system consists of the glass frame design and the mounting system for the PCB and hardware components. The frame design will be 3D printed. The goal would be to use premeasured plastic mounting points and screws to mount all components within the hollow frame.

## Application System
The application system consists of image processing, audio transfer, and user interface. The image will be processed, the plant will be identified, and then have audio transferred back to the speaker in the peripheral system. We will develop this application for iOS and interact with the glasses via Bluetooth.

# Criterion For Success

The following goals are fundamental to the success of our project:

- Successful User Flow - The user should be able to look at a plant, press the interact button, and then wait for the system to return the audio of the plant description.
- Accuracy - The final prototype should be able to correctly identify plants 75% of the time.
- Strong Bluetooth Connection - There should be an uninterrupted Bluetooth connection between the glasses and the mobile - device. Additionally, the glasses should be fully operational within a 15-foot range of the mobile device.

The goals below are considered reach goals, and if not accomplished would not hinder the success of our project:

- Bone Conduction Audio - An alternative way of relaying the audio to the user that involves transmitting sound vibrations through the bones.
- Adjustable Audio Volume Level - Within the application system the user will be able to adjust the volume.
- Voice Activation - In addition to the push button, users have the ability to speak to begin the system process.
- Heads-up Display - A display on the glass lenses to aid in relaying the information to the user.

STRE&M: Automated Urinalysis (Pitched Project)

Featured Project

Team Members:

- Gage Gulley (ggulley2)

- Adrian Jimenez (adrianj2)

- Yichi Zhang (yichi7)

The STRE&M: Automated Urinalysis project was pitched by Mukul Govande and Ryan Monjazeb in conjunction with the Carle Illinois College of Medicine.

#Problem:

Urine tests are critical tools used in medicine to detect and manage chronic diseases. These tests are often over the span of 24 hours and require a patient to collect their own sample and return it to a lab. With this inconvenience in current procedures, many patients do not get tested often, which makes it difficult for care providers to catch illnesses quickly.

The tedious process of going to a lab for urinalysis creates a demand for an “all-in-one” automated system capable of performing this urinalysis, and this is where the STRE&M device comes in. The current prototype is capable of collecting a sample and pushing it to a viewing window. However, once it gets to the viewing window there is currently not an automated way to analyze the sample without manually looking through a microscope, which greatly reduces throughput. Our challenge is to find a way to automate the data collection from a sample and provide an interface for a medical professional to view the results.

# Solution

Our solution is to build an imaging system with integrated microscopy and absorption spectroscopy that is capable of transferring the captured images to a server. When the sample is collected through the initial prototype our device will magnify and capture the sample as well as utilize an absorbance sensor to identify and quantify the casts, bacteria, and cells that are in the sample. These images will then be transferred and uploaded to a server for analysis. We will then integrate our device into the existing prototype.

# Solution Components

## Subsystem1 (Light Source)

We will use a light source that can vary its wavelengths from 190-400 nm with a sampling interval of 5 nm to allow for spectroscopy analysis of the urine sample.

## Subsystem2 (Digital Microscope)

This subsystem will consist of a compact microscope with auto-focus, at least 100x magnification, and have a digital shutter trigger.

## Subsystem3 (Absorbance Sensor)

To get the spectroscopy analysis, we also need to have an absorbance sensor to collect the light that passes through the urine sample. Therefore, an absorbance sensor is installed right behind the light source to get the spectrum of the urine sample.

## Subsystem4 (Control Unit)

The control system will consist of a microcontroller. The microcontroller will be able to get data from the microscope and the absorbance sensor and send data to the server. We will also write code for the microcontroller to control the light source. ESP32-S3-WROOM-1 will be used as our microcontroller since it has a built-in WIFI module.

## Subsystem5 (Power system)

The power system is mainly used to power the microcontroller. A 9-V battery will be used to power the microcontroller.

# Criterion For Success

- The overall project can be integrated into the existing STRE&M prototype.

- There should be wireless transfer of images and data to a user-interface (either phone or computer) for interpretation

- The system should be housed in a water-resistant covering with dimensions less than 6 x 4 x 4 inches
