Emergency vehicle approach warning system
First Claim
1. For use in providing an audio and visual warning of an approaching emergency vehicle;
- a transmitting and receiving device comprising an injection molded plastic shell having open backs receivable of transmitting and receiving circuit boards along guide tracks molded into side walls of the plastic shell;
audio means for providing the audio warning;
visual means for providing the visual warning;
a means for mounting the transmitting and receiving devices into emergency vehicles and motor vehicles respectively;
a means for attaching the transmitting and receiving antennas to emergency and motor vehicles respectively, wherein said means for attaching transmitting and receiving antennas to emergency and motor vehicles includes a coaxial lead extending from their respective transmitting and receiving devices, said transmitting and receiving antennas further including a cylindrical juncture connected to a terminal end of the said lead, said juncture including openings at each end for receiving severed and prepared ends of the original equipment vehicle antenna, wherein the ends of the juncture are crimped to electrically connect the severed ends of the original transmitting and receiving antenna; and
a means for attaching positive and negative leads to existing emergency and motor vehicles respectively.

Abstract
For use in warning motorist, especially those who are hearing impaired, of an approaching emergency vehicle, a new and useful invention comprises a transmitter which is installed into an emergency vehicle and activated upon an emergency run. A low frequency signal is sent out over the emergency vehicles original equipment antenna system and is picked up by motorist having a receiver unit mounted to their dash panel. The signal is processed into visual and audio warnings whenever a transmitting emergency vehicle is within close proximity to the receiving vehicle. The receiver is on full time when the motor vehicle is in operation thereby allowing suitable response time for motorist to take appropriate action in yielding to the emergency vehicle. The transmitter does however have an on/off switch as well as a visual and audio means for monitoring the transmitted signal.
