After walking off and leaving my briefcase countless times, I need this device. One section the transmitter, is fixed to my briefcase, the other section, the reciever, credit card sized is in my pocket. Once the reciever determines that I am more than 60 feet away from the transmitter, it vibrates, reminding me that I might be leaving my briefcase behind me. The reciever is equipped with a 5 to 15 minutes "snooze" function, but cannot be disabled. This prevents me from turning it off, then forgetting and leaving it off.

Sadly, without the electric shock option. [8th of 7, Oct 17 2004]

Could get annoying when you visit the gym on your way home from work. How about a delay snooze function you can set for up to an hour? Could be a feature accessible by password that emits a quiet blip every five minutes to remind you that it's in delay mode.

Add in a locator like those avalanche transceivers to help find where you've left it too. (+)

This is baked. I've owned one at some time in the past, though I never used it. Don't know if the commercial ones come with a snooze function, though.

There are "child alarms" that work like this. When the transmitter gets out of range (variable) of the receiver, the receiver starts to bleep. The transmitter is nailed or screwed to the child, and the adult carries the receiver (about the size of a pager) in a pocket or clipped to a belt. It wouldn't be hard to make it vibrate instead of bleep. Sadly, there is as yet no version commercially available that gives the errant child a painful electric shock if it wanders off ......

Available license-free in the UK, costing between GBP £20 and £40. Battery life is only a few hours, so you might want to add a solar recharger.

????????

Anyway, the device you describe is ... a piece of string.

kinda hard to use the string in a cubicle farm, or a classroom

Why have a snooze? Just hit the "Yeah I f*cking know." button and until the device comes back into range, then goes out of range again, your beeper won't go off.
