Although the Zune didn't offer too much innovation in comparison to the bevy of other digital audio players out there, the wireless streaming (however effective) did have a leg up over the non-sharing competition. A California-based teenager, however, has supposedly changed all of that with her (well, her dad's) engineering efforts, as the SnoopTunes NoeStringAttached transmitter purportedly opens up the shared lines to iPod users. While you can certainly color us skeptical, the bullet-shaped device managed to grab some airtime on an MSNBC broadcast (shown after the jump), and reportedly transmits your music to other NoeStringAttached users "withing a 15 foot radius," touts five separate channels for non-chaotic field trip usage, and only runs you about $60 for an entire kit. While the slapped-together eBay sales page doesn't elaborate on what type of transmitting protocol is being utilized, we're here to inform you that this thing most certainly won't allow you to beam your song to another iPod -- not even for a measly 72 hours. Truth be told, we're not even sure this thing actually functions as advertised, but even if it does, we really hope you don't mind following your new best friend around fairly close if you're interested in tuning in to what they have to listen to.

Swimming is fun, but drowning, most certainly, is not. The makers of SenTAG know this, and have developed a system that monitors swimmers' depth and motion, alerting them, with a series of alarms and LEDs, if they might be in danger. The set-up, which is designed mostly for public swimming holes, consists of radio/ultrasound transmitters (worn around swimmers' wrists) and a base station that alerts rescue personnel if someone isn't responding to the alarm. No building modification is required for installation, meaning there won't be any wires running through or around the water and operating cost is kept relatively low. The most exciting part for us, though, is that the whole rescue process is now one step closer to being completely electronic. Eventually, the SenTAG could be used to signal a Strider robot, which could drag the victim back to land where the CPR bot could be applied. But, don't worry lifeguards, that day is still a long way off.
