Off the Beaten Path: Xandem’s Party Detector
Created at the University of Utah by Dr. Joey Wilson and Dr. Neal Patwari, TMD is based on “radio wave synergistic sensing” and designed for easy integration into existing systems. Unlike traditional microwave sensors that depend on radio wave reflections, motion sensing is done via communicating nodes in a wireless mesh network that sense disruption in a defined area. And because the wireless networks penetrate through walls, furniture, and other solid materials, TMD sensors can be hidden from view.
The system is even able to quantify motion and detect the difference between a single intruder and a crowd of people, according to Wilson. He sees endless applications for TMD technology, including party detection. “When parents leave their kids at home, they can be notified if a party is occurring.”
