Smart LED Bulb K**ws When Someone Falls
Smart LED Bulb K**ws When Someone Falls
  Union Tool Co out of Japan developed a Smart LED light Bulb that can monitor what’s going on in the room below it. Specifically, it was designed to automatically detect an elderly person falling and call for help. The Bulb has a 24 GHz milliwave radar, developed by Panasonic, pointing downward that can measure the distance to a person’s skull below it. If this distance suddenly and rapidly increases, the Bulb assumes Someone fell and uses an on-board networking chip to send a signal that can be picked up by a professional service or relayed to family or caretakers. The Bulb hanging at 3 meters above ground can cover an area of 13.2 square meters (142 sq ft). Having these bulbs throughout the house should be sufficient to cover most of the living space where accidents can happen.
