Smart LED Bulb Knows When Someone Falls

"Smart LED Bulb Knows When Someone Falls":
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.
