source: New Scientist June 1 2002 p23

Temko of Tokyo has developed a device allowing handlers to control dogs at a distance. The handler uses a loudspeaker transducer attached to the dog’s head at the back, and this transducer sends sound to the dog’s eardrums via its skull. The device could be helpful for handlers of rescue and police dogs.
