We\u2019re a few days into CES now, and amid the demos, launches, meeting, greeting, keynotes and all the walking, there’s one thing on a lot of people\u2019s minds: sleep. So, Marketplace\u2019s Lily Jamali stopped by the National Sleep Foundation’s booth to meet some folks there thinking about sleep. She spoke with Biquan Luo, co-founder and CEO of Lumos Tech, whose company makes what looks like a regular sleep mask, but has embedded LED lights. It\u2019s designed to help recalibrate a user’s sleep schedule.
