Ultrasonic Shark-Tag Locator System For Iver2 Auv, Nathaniel Garcia
Ultrasonic Shark-Tag Locator System For Iver2 Auv, Nathaniel Garcia
Computer Engineering
The purpose of this project is to develop a system for tracking an ultrasonic underwater transmitter that can be integrated into an IVER2 AUV to allow it to follow and monitor tagged sharks in the ocean for scientific research.
The system consists of a four main components including a shark-tag, two hydrophones, a filter/amplifier & threshold detector circuit, and a microcontroller.
This project, while not completing field testing and integration with the IVER2, is a proof of concept of a system that utilizes passive sonar to determine a bearing from the system to a shark-tag transmitter. Additionally, it devised several …
Irrigation Leak Detection: Using Flow Rate Sensors To Detect Breaks In An Irrigation System, Adam Openshaw, Kalvin Vu
Irrigation Leak Detection: Using Flow Rate Sensors To Detect Breaks In An Irrigation System, Adam Openshaw, Kalvin Vu
Computer Engineering
This report details the exploration and invention of a mechanism that can detect breaks in an irrigation system. With the ultimate goal of conserving water, we have designed an inexpensive, self sustaining flow rate monitor that can be used to identify anomalies in an irrigation system and wirelessly communicate the status of the system to a base station. Our implementation can also determine the direction of the anomaly based on the nature of the anomaly itself. This means that multiple monitors can be used to pinpoint the location of a break within the system in addition to merely detecting its …

Characterization Of The Rfx400 For Use In Software Defined Radio, Edward Adams
Computer Engineering
While software defined radio is an extremely flexible technology that is fairly rarely used, as a single purpose radio is much cheaper, it provides an excellent means of learning RF and communications skills through the lens of digital electronics, and it would behoove a Cal Poly student interested in these areas to take on a project in software defined radio. This project aims to lower the barrier to entry for future students to undertake such a project. The use of an up-converter/down-converter is documented for future students to interface with.
