Children's tracking device invented
Children getting lost in theme parks could become a thing of the past thanks to an invention pioneered at Birmingham University.

Engineers at the university have developed a bangle that emits a signal, allowing missing youngsters to be easily located.

The "Geobangle" uses global positioning by satellite, or GPS - the same system used in some cars as a navigational aid.

Parents would be encouraged to rent out a Geobangle from the theme park for their children to wear during a visit, with control room staff on hand to pinpoint their exact location if they get lost.

Tim Brown, from the department of electrical, electronic and computer engineering's company Wave Solutions, said he hoped the bangle would soon be available at places like Alton Towers.

"We have received extensive interest in the prototype of the Geobangle from theme parks in the UK and would like to put it into production if a suitable company were to come on board.

"The Geobangle has many other applications and could also be used by schools or even for pet tracking."
