# Problem
Urine sample analysis is essential for managing patients with chronic disease but these tests are often tedious for the patients to conduct and usually involve providing a sample to a lab or collecting urine over 24 hours. Moreover, patients and doctors may be missing out on valuable information from the tests if the patient cannot come in regularly to provide a sample.

# Solution

Create an autonomous system that allows for the sanitized movement of urine/cleaning liquid, which we refer as “solution,” to a glass slide to be imaged and sent wirelessly to a workstation for a doctor or technician to be analyzed. This takes out the middleman of the need for samples to be processed at a separate lab, and gets the results from health professional to patient with haste.

# Solution Components

## Pump

This will drive the solution from the float fluid sensor, and deliver it to the imaging window/slide. Whilst waiting from the flow sensor and image capturing response signal from the control system, pressure will be built to evacuate the slide (perfusion chamber) so the next solution set can be brought in. We won’t need a high power pump as the capacity of the slide is minimal, but the pump will most importantly create the pressure differential for exit flow.

## Camera

This camera will be attached to a microscope focused on the imaging window through which the sample flows. Based on when the pump activates and the current sample is in the window, it will take multiple sample photographs that will be uploaded to a network drive to be viewed by a doctor. This camera should be able to capture photos that visualize the cells and cast in the urine as well as be able to have the right focus to capture the image.

## Control System

The control system will use an STM8 or STM32 microcontroller to control the pump and camera systems, as well as send the sample photographs to the analysis location. To do this, it will use either a resistive sensor or float device to determine when the urine is at the threshold value, run the pump, and take input from a flow sensor to transfer .5mL (amount variable to specification) of urine to the slide. It will then trigger the camera to take a photo, store the photo, and send it to an external computer for human analysis. It will repeat this process up to 5 times, after which it would send the urine to a waste reservoir by flushing the system and observation slide with a cleaning fluid.

# Criterion For Success

-The system should be completely autonomous from the point the urine is collected to uploading the images to the network drive.
-The system should be hygienic and leak-free.
-The images captured should be of sufficient quality for a doctor to analyze the sample.
-The imaging window of the microscope should be cleaned between samples and the entire system should be flushed once all the data is collected.

El Durazno Wind Turbine Project

Featured Project

Partners: Alexander Hardiek (ahardi6), Saanil Joshi (stjoshi2), and Ganpath Karl (gkarl2)

Project Description: We have decided to innovate a low cost wind turbine to help the villagers of El Durazno in Guatemala access water from mountains, based on the pitch of Prof. Ann Witmer.

Problem: There is currently no water distribution system in place for the villagers to gain access to water. They have to travel my foot over larger distances on mountainous terrain to fetch water. For this reason, it would be better if water could be pumped to a containment tank closer to the village and hopefully distributed with the help of a gravity flow system.

There is an electrical grid system present, however, it is too expensive for the villagers to use. Therefore, we need a cheap renewable energy solution to the problem. Solar energy is not possible as the mountain does not receive enough solar energy to power a motor. Wind energy is a good alternative as the wind speeds and high and since it is a mountain, there is no hindrance to the wind flow.

Solution Overview: We are solving the power generation challenge created by a mismatch between the speed of the wind and the necessary rotational speed required to produce power by the turbine’s generator. We have access to several used car parts, allowing us to salvage or modify different induction motors and gears to make the system work.

We have two approaches we are taking. One method is converting the induction motor to a generator by removing the need of an initial battery input and using the magnetic field created by the magnets. The other method is to rewire the stator so the motor can spin at the necessary rpm.

Subsystems: Our system components are split into two categories: Mechanical and Electrical. All mechanical components came from a used Toyota car such as the wheel hub cap, serpentine belt, car body blade, wheel hub, torsion rod. These components help us covert wind energy into mechanical energy and are already built and ready. Meanwhile, the electrical components are available in the car such as the alternator (induction motor) and are designed by us such as the power electronics (AC/DC converters). We will use capacitors, diodes, relays, resistors and integrated circuits on our printed circuit boards to develop the power electronics. Our electrical components convert the mechanical energy in the turbine into electrical energy available to the residents.

Criterion for success: Our project will be successful when we can successfully convert the available wind energy from our meteorological data into electricity at a low cost from reusable parts available to the residents of El Durazno. In the future, their residents will prototype several versions of our turbine to pump water from the mountains.
