Purdue researchers have created a technology to help prevent dust explosions. The technology uses an image- and video-based application using OpenCV algorithms that detect explosible suspended dust concentration. The app requires a camera or video recording device to image and determine the suspended dust level, and the app can accurately distinguish the dust from normal background noise. App testing has shown that the algorithm successfully recognized 95 percent of sawdust and 93 percent of cornstarch particulates in the air.

According to Kingsly Ambrose, an associate professor of agricultural and biological engineering who leads the research team, current technology to detect sus-pended dust is often expensive, difficult to install, and separates dust matter into multiple filters that must be weighed and further manipulated for analysis.

Purdue University is a public research university in West Lafayette, IN. The Purdue Research Foundation Office of Technology Commercialization has a comprehensive technology transfer program among leading research universities in the US. The office’s activities benefit the economic development initiatives of Purdue University and benefit the university’s academic activities by commercializing, licensing, and protecting Purdue intellectual property. The office is run by the Purdue Research Foundation, a private, nonprofit foundation dedicated to advancing the mission of Purdue University. (11/20 pbe)
