Anybody heard of this yet? It's a women's bra with built-in heart rate monitor, wireless phone, and GPS receiver. Supposedly, when the woman wearing it experiences a sudden jump in heart rate (such as when she is the victim of an assault) the wireless phone will transmit a distress signal to the police and give her location using the GPS.
I'm sure that a version that can alert a father when the bra on their teenage daughter is unclasped would be a great seller too!
