Elephant Behavior Monitoring Collar
Elephants face many threats in the wild including poaching, habitat loss, and disease. A major goal in elephant conservation is to monitor their activity at all times so that there can be rapid response to potential threats, but this is a problem that cannot be solved by manpower alone. Instead, an edge-AI device on the animals could radio telemeter behavioral inferences and alert rangers quickly. To train and test this device, we can work with the African Elephants in our care. Current off-the-shelf systems are either very expensive, are not fully waterproof/impact proof, or do not utilize LoRa or onboard AI. This project involves developing an as-small-as-possible sensor stack. This will include a 9-axis IMU sampled at 25 Hz, and a board capable of housing a tinyML machine learning model. The device should periodically send device status properties and behavioral information over LoRa. The device housing needs to be elephant-proof, IP67, and able to withstand a portion of the elephant's weight. The outer face of the housing should hold a solar panel and the battery capacity should allow for indefinite use. LoRa signal strength should be considered when choosing materials as it's important the range is not inhibited greatly by the enclosure. Manufacturing of the device should be able to be reproduced with our lab’s current fabrication capabilities and rapidly accessible parts.

EUV Source Module Metrology Tool
ASML focuses on developing and manufacturing Extreme Ultraviolet (EUV) lithography machines essential for producing computer chips. This process uses liquid tin ablated by a CO2 laser, including approximately 2,000 gas holes that guide tin to the proper disposal. Currently, ASML inspects these holes by hand which is inefficient and dangerous. Team Deep Purple has been tasked with designing a dual-axis robotic camera system to check which holes are blocked by tin debris. This increases the efficiency and safety of the cleaning process.

Laminar Water Jet with Micro Bubbles
In the swimming pool industry, there are various designs of water features that use water and light to accentuate the swimming pool aesthetics. One challenge is to bring enough light to a long stream of laminar flow to create a bright enough visual effect for the user. One proposed solution is to add small bubbles to this stream of water which will refract the lighting and make the stream “glow” more brightly when viewed by the user. This project is to start with a basic water feature and design a method of creating the micro bubbles to create the desired effect. The bubble size and quantity will need to be controlled and adjustable for testing to get the optimal effect. An ideal project will develop a method of measuring the size and amount of bubbles generated at various positions along the stream to also measure “bubble life”.

MQ-9A Remotely Piloted Aircraft Radome Redesign
Redesign the MQ-9 radome for two separate but equally important design goals. First, the radome should be streamlined for efficient operations at cruise. Secondly, the radome should be redesigned such that it can be opened and either removed or placed into the locked position within 30 seconds. The design may use a full opening radome, panels, or some other method to facilitate common maintenance and inspection actions. Any portion of the aircraft that is opened or removed should be designed to remain safely in place during wet and windy conditions of up to 20 knots. Any design shall note keep out zones for RF transmissibility.
