The Wearsafe tag allows its user to call out to friends and family by way of a cell phone--without actually using the phone. Once pressed, the Wearsafe tag sends constant audio through the tag holder's phone--even capturing and saving audio from a full minute before the tag has been activated--giving anyone connected to the user's phone (by an app) an idea of what is happening, and how to respond. All those connected to the Wearsafe user's phone can also share in a live chat room, so everyone linked will know if a response has been sent, what sort of response and where everyone in the room is located. As for the tag, it silently vibrates once an alert is sent, and again once a response has been placed. Tags are $149.99, which includes the tag itself and a lifetime subscription to Wearsafe service; for more information visit wearsafe.com. (Be sure and read the Terms of Service in relation to possible cancellation or non-return of device fees.)
Vigilant personal alarm with backup whistle
Designed to look like a car alarm fob, the Vigilant 130dB personal alarm emits a 130-decibel alarm at the push of a button. To give you an idea of how loud that is, a Purdue University report says it's the volume of a military jet aircraft taking off from an aircraft carrier with an afterburner at 50 feet. Last we checked, no one (a student or otherwise) can yell that loudly (the average scream registers roughly 90 decibels), so this alarm promises to summon the neighbors. And that volume can also be painful to the ears of those in the vicinity. In addition, there's a built-in backup whistle for use in case the battery dies. Available in red, pink and black.
