Delay-Based Physical Unclonable Function Implementation, Abigail Aguirre, Michael Hall, Timothy Lim, Jonathan Trinh

Electrical and Computer Engineering Senior Theses

As we venture further into the 21st century, it becomes much clearer that hardware security is at the forefront of many challenges that we face today in ensuring that data is protected. “Keys” (a sequence of bits) can be used to unlock pieces of data and is a concept that is pervasive throughout cryptography, but storage in memory makes this sole method nonviable. To make the approach more practical, one can dynamically generate a key through a Physical Unclonable Function (PUF). PUFs are circuit primitives that use intrinsic variations of microchips created during the manufacturing process to generate a unique …

Disaster Relief Communications Box, Kyle Johnson, Karter Naito

Electrical and Computer Engineering Senior Theses

This report showcased a project from Santa Clara University's Senior Design Showcase. Current senior electrical engineering students Karter Naito and Kyle Johnson have created a Natural Disaster Relief Communications Box that they hope will have a big impact on natural disasters. The device had three different power sources to provide power to operate the device : plug-in wall charger , solar panel, and a handle crank. Powered by a Raspberry Pi 4, it could set up a local Wi-Fi network for people to connect to and receive and send important information. To increase the reliability of the device , it …

3dscanner, Thomas Heckman, Robert Kalb, Shreyes Nallan

Electrical and Computer Engineering Senior Theses

This project entails designing, prototyping, and testing a 3D scanner. The device that we are building uses LIDAR to take position data of a 3D object, then analyze and encode the sensor data as an STL file that can later be 3D printed out at the same resolution. We aim to build an affordable, high-performance 3D scanner that takes advantage of the falling cost of LIDAR in order to bring 3D scanning capabilities to individuals, the maker community, and even small businesses.

We begin this process by choosing a sensor, the YDLIDAR X4, as our primary method of taking position …

Solar Panel Monitor And Data Logger, Ryan Murray, Sharan Singh

Electrical and Computer Engineering Senior Theses

When deploying systems halfway across the world, having some system for monitoring their performance and status is essential. All We Are, in their mission to build solar panel installations in Uganda, encounters this problem daily. For our project, we worked with All We Are to deliver a system to monitor these solar installations. Building an embedded solution that can communicate with the solar installations and upload the data to the cloud allowed us to accomplish this goal. Our system connects data from the existing solar panel infrastructure to the cloud. The platform of our system is a Raspberry Pi microprocessor. …

Transmission System For Wireless Charging In Three-Dimensional Space, Bradley Shirley, Amritpal Singh

Electrical and Computer Engineering Senior Theses

Current methods of wireless power transfer (WPT) limit the mobility and usage of a device when it is actively charging. Here, a three-dimensional wireless power transfer technique known as quasistatic cavity resonance (QSCR) is studied in arbitrary geometries and practical scenarios. Physical fabrications and simulations demonstrate the viability of QSCR along with techniques for lowering the resonant frequency to meet safety standards. Two methods of lowering the resonant frequencies are presented, one by changing the physical dimensions and the other by increasing the systems capacitance. It is shown that QSCR is a feasible option to wirelessly transfer power in a …
