The Bat System
3D Ultrasonic Positioning for People and Objects
Bats are lightweight wearable devices featuring ultrasonic transducers, a 433Mhz radio transceiver and a long-life battery, amongst other components. They are used throughout the DTG to precisely locate people and objects, providing a location-aware environment. Each Bat is distinguished by a unique identification code and permits input through two small buttons on its side.
