Timothy created several projects for his work at Purdue University. One project involved creating a board with lights and switches that students could easily connect to and disconnect from. A second project was a simulated car bumper with sensors and a speaker to simulate backing up alerts. The third project was an assistive device created with international students to help the elderly put on and remove shoes, with a platform that raises and lowers and built-in features like a shoe horn.

Project 1
This project was for my work at Purdue University. My boss had asked me to create a
board that all of the lights could be mounted to along with some interactive switches. It also
needed to be able to be hooked into easily so the students could hook up and start working and
then disconnect and leave lab on time. I chose an acrylic board to attach everything to. I used
CAD software to draw out all of the holes that would need to be drilled out. I then plugged the
software in to a laser that would cut all of the holes for me to keep it all uniform. For the quick
connection I decided to use 2 boards one for the students and the other would be the project
shown above. The one for the students would just have a terminal strip and the wires already
connected. The students would keep those as a work space and hook into them. Then when
they were ready they would attach their board through a quick connect to the main project.

Project 2
This was designed for my work at Purdue University. I was tasked to make a simulated
car bumper with the alert system for when backing up. The small holes have motion sensors in
them. The large circle in the middle is a speaker for the sound of the beeping when backing up.
I wanted to utilize the boards the students had already used to connect to this project also. I
put the same quick connect on them so that they would be able to connect in the same way.

In this project I was teamed with 3 American students and 5 students from the
Netherlands. We were tasked to come up with an assistive device to help the elderly with their
mobility. We had decided to assist people with putting on their shoes. This device is an assistive
device to help the user put their shoes on and take their shoes off. The platform raises and
lowers so that the user will never have to bend over to pick up or change out the shoes that
they want to wear. The device has a built in shoe horn so that the user can slide their foot in to
their shoe with ease. The back bumpers hold the shoe in place while the user takes their foot
out. The front rocker helps hold the shoe in place when the want to put their shoe back on. The
handles are meant so that the person can maintain their balance while they are using the
device. It is motor driven for the lifting of the platform. For this project I created the assembly
drawing in Solidworks 2015. I also created all of the mechanical drawings that are shown for
examples of my work. This project is still in progress. When reviewing my portfolio if you
would like an update on it I would gladly be willing to give it to you. In the next couple of
months, I should have a fully functional prototype and photos of such to show. Feel free to
contact me about the project at the given email or telephone number.
