Knot / safety accessory


Knot is a powerful search tool for lost and potentially abducted children.
It has two parts.Child and guardian,which
communicate each other through ZigBee protocol.
The Kid's Terminal continually detects pressure on the feet and monitors the distance between the child's terminal and guardian's to keep them at a safe distance.
The Guardian Terminal makes judgments by
calculating the signals received from the kid's terminal to send vibration feedback to the user.
