Teslas might get a sensor that detects a child left in a hot car

Tesla is working on a sensor that could detect a child being left in hot car, Reuters reported Thursday. The automaker asked the Federal Communications Commission (FCC) to approve a short-range millimeter-wave sensor, that would operate at a higher power than is currently allowed. The device would have seven antennas (three for receiving and four for transmitting signal) and a radar front-end unit, and would be able to "see" through soft materials such as a blanket covering a child.  The device would also be able to differentiate between a child and an object on the seat, and could even detect the child's breathing patterns and heart rate, according to Tesla.  Read more...More about Tesla, Tech, and Transportation
