It seems that when children are drowning, they don’t thrash about, but instead they first go silent.

Today’s invention is a life-saving technology which takes advantage of this scary information.


Each child entering a body of water would put on a waterproof collar with a throatmike and a small transmitter embedded.

Each child’s signal would be monitored by a system on dry land.

In the event that a given youngster was substantially less noisy than its own average for say 20 seconds, a light on the collar would illuminate, alerting adults in the vicinity.
