(from the Knoxville News Sentinel story by Carly Harrington)  Jenna Johns’ baby had stopped breathing for 20 seconds.

With a remote monitoring system developed by Knoxville-based RDI Technologies, Johns, the company’s chief operating officer, was able to rewind the video and watch what happened with side-by-side playback of the video and breathing waveform.

RDI 01The application is one of three health care and industrial markets Knoxville-based RDI Technologies is pursuing for its patented platform technology.

“The technology uses video cameras to see things that we can’t see with our eye,” RDI Technologies CEO Jeff Hay said. “We can take a video input and actually turn it into data. We can measure it and turn it into something that we can quantify. We can look at the way machines move; we can look at the way structures vibrate or a baby’s chest moving.”

Hay invented the technology 10 years ago while at the University of Louisville. He left in 2013 to start RDI Technologies to bring the technology into commercial markets.

By pointing a digital camera in the direction of the subject, RDI Technologies uses every pixel as an optical sensor capable of measuring motion or vibration without requiring direct contact.

RDI 02The company, which recently moved into new corporate headquarters off Technology Drive in West Knoxville, is focused on advancing products for sleep monitoring, bridge inspection and machine analysis.

“All three are at points of different levels in the market,” company President Bob Wilson said. “All of them are huge markets, which makes it so interesting. The power of what we do is the actionable information. Seeing is believing is our motto, because if you can see it, then you can start believing what’s going on. The ability to see it and understand that information, that’s the key.”

RDI Technologies has already licensed the technology on the machinery side with Charleston, S.C.-based Allied Reliability Group.

The company, however, opted to develop its own bridge monitoring system that was launched earlier this year. It is currently working with three of the largest bridge-inspection companies in the southeast.

The BridgeView software provides real-time data collected by using remote video imagery as traffic travels across a bridge. What would typically take a crew to do in four days, can be done in two hours, Wilson said.

RDI 03“That’s the difference in the quickness and ability to capture that information in a more timely manner,” Wilson said.

For its respiration system, which is currently in the testing phase, RDI Technologies is looking to partner with an industry leading company to take it to market. Those efforts are being spearheaded by Johns, whose daughter had been diagnosed with central and obstructive sleep apnea.

Unlike other sleep monitoring devices, RDI’s system doesn’t require contact, visible light or the person’s face to be visible.

“From adolescence to as you get older, we see this as a lifelong product that people can use in all stages,” Hay said.
