Wireless traffic calming, cautioning, early warning and emergency notification system
First Claim
1. A wireless notification system comprising:
- a) a transmitter and microprocessor configured to transmit at a data rate up to approximately 500 kilobits per second limited to a range of up to approximately 500 meters;
b) a codec coupled to said transmitter and microprocessor, said codec configured to convert an analog audio signal to a digital signal for transmission by said transmitter to a transceiver in a vehicle configured to receive said digital signal, and generate an audio signal corresponding to said analog audio signal for playback in said vehicle.

Abstract
A traffic calming (broadly defined as methods and apparatus for the purpose of reducing or otherwise controlling vehicle speeds and improving safety appropriate to the state of the road), cautioning, early warning and emergency notification system using secure wireless transmitters, receivers and transceivers for localized point to point notification. Static, desktop, portable and vehicle mounted transmitters/transceivers are automatically or manually triggered to transmit cautioning, early warning or emergency alert messages within a specified range to desktop, portable or vehicular-mounted receivers/transceivers, notifying the user of the receiver/transceiver of an approaching traffic calming or cautioning situation (children crossing, train crossing, construction detour, accident scene, etc.) or emergency situation (approaching emergency responder vehicle, such as police, firefighters, ambulance, etc). The system utilizes secure, localized point-to-point wireless technology to overcome typical impediments to effective targeted traffic calming, cautioning, early warning and emergency notification at home, work and in a vehicle by allowing emergency responders and others responsible for cautioning, early warning and emergency notification, who have one or more transmitter/transceiver, to communicate directly and effectively with the immediately affected individual(s) within a specified range, who have at least one receiver/transceiver.
