KSL TV LOGAN — A new high-tech machine that can check your temperature and whether you are wearing a mask is expected to keep businesses like ski areas open and events running safely. The device will be used Wednesday at the Ellen Eccles Theater in Logan. Creator Dustin Hansen stood in front of a Firefly Power Display to show KSL how it works. The device could be described as a fancy, high-speed thermometer. "My temperature is 96.2," Hansen said, looking at the display. "Please wear a mask," the machine reminded him. "So, I'm not wearing a mask, shame on me," Hansen said. The machine strongly interrupted and reminded him again to get a mask.
