Wireless Innovation GIZMO GEEKS 2011 The document proposes an idea for a system to help drivers locate available parking spaces more efficiently. The system would involve pressure switches under parking spaces connected to small transmitters that broadcast signals when a space is vacant. A receiver in a car could trace the signal to find the open spot, saving time spent searching. Potential advantages are saving time and low cost, and it could help prevent car theft if modified to send signals to cell phones. A disadvantage is receivers would need supporting software.
