Cant find your keys? Give them a call! Printer Friendly Version
How about an electronic device which is attached like a keyring with your keys. It will have a sensor. It will send signals and receive signals. If you have lost your keys you could dial (on your mobile phone) a personal signal number that would transmit to the keyring, causing an alarm to be set off! Or if you lose your phone you could press the keyring button which will activate the alarm on the phone. With a flashlite attached to the keyring as well this could be a handy object.

There could be a small self-contained, battery-powered motor and battery that could last several hours. It would then be retrieved and its information analyzed. For longer durations, it could have a skin comprised of solar-collecting cells. Universities around the world could competitively bid to get a contract to build these.

Personal Locator Printer Friendly Version
Using Cell Phone Technology create a device that can be placed on elderly and small children so that when they get lost they could be located. Have it with an automatic on so that they wouldn't have to press a button to answer. You could just start talking to them and them to you. Also include a panic button on it for emergencies.
