"Some firsts represent truly monumental achievements. Others, like the world's first production-ready Bluetooth Low Energy heart-rate chest belt, are just a mouthful. This little black belt claims to be the very first of its kind, and promises to \"spur the development of a whole new range of... health and fitness apps,\" by harnessing the power of Bluetooth Low Energy to pump heart rate stats to your mobile phone. Of course, that deluge of new fitness apps will have to wait until a Bluetooth 4.0-compatible phone hits the market. In the meantime, we wouldn't expect the black chest strap to pioneer any new fashion trends."^^<http://www.w3.org/2001/XMLSchema#string>
