Safety Turtle...uses a water sensor that's worn on a child's wrist. If the child falls into a pool, the device sends a one-way radio signal to a receiver typically placed inside a home that triggers a loud alarm.
The Virtual Lifeline...is a small sensor worn by boaters that can be attached to a swimsuit or life vest. If they fall into the water, it sends a signal to the ignition, immediately shutting it off and stopping the propeller.
