Rochester Section AES/COM Chapter Technical Presentation
After several years of research and development, WiSe-Net lab researchers at University of Maine created a standalone wireless device for detecting air leaks inside pressurized space vehicles or habitats. This system includes multiple ultrasonic sensors that listen for acoustic waves emitted from a small hole causing air leak. The large amount of data collected from these sensors are then statistically analyzed using a number of different algorithms and signal processing methods to find the most likely location of the leak. This can help save crew time, save precious air in deep space missions, and has the potential to be used here on earth for safety at homes or inside gas and oil pipelines.

Wireless Leak Detection with Applications in Earth and Space
This presentation discusses hardware, software, and algorithmic challenges for localizing air leaks on the International Space Station (ISS) using an array of ultrasonic sensors. Three devices were built, flight certified, and deployed to the ISS for data collection in Jan 2017. This research was funded by NASA and featured on Discovery Channel, Phys.org, and several other media outlets in 2016.
