US 6,384,776 B1 · EM signal detection and position broadcasting system and method

Abstract

A system and method for alerting a driver to the presence of an EM signal from a police speed sensor signals (RADAR/LADAR), emergency vehicle signals and traffic hazard warning signals using RADAR/LADAR detectors and coupled GPS positioning system an transceiver. The system receives electromagnetic signal emissions and records the location of the Signal, providing that information to a central processor. A GPS system constantly updates the vehicle position so that the processor can note the vehicle position at the time the Signal was received. The GPS position signal is reformatted and broadcast to other vehicles having similar units. When a position signal is received by the transceiver, it is stored and compared to the present position of the driver's vehicle. When the vehicle is within a predetermined range if the police sensor position that was broadcast, a signal is sent to the driver in audible, visual, voice or a combination of these means notifying the driver that the automobile is within range of a Signal. A base station coordinates and transmits reports of EM signal to drivers.

Dependent claims

An electromagnetic (EM) signal detection and position broadcasting system comprising:

a plurality of integrated units, each integrated unit mounted in a vehicle of a first party and comprising;
a global positioning system (GPS) receiver adapted to continuously output a changing determined position;
a microprocessor comprising storage connected to the GPS receiver and adapted to receive the changing determined position;
an EM signal detector connected to the microprocessor adapted to provide a notification to the microprocessor when a non-reflected EM signal from a third party is received;
the microprocessor further comprising instructions stored in the storage adapted to designate an EM signal position calculated from the changing determined position when the notification is received and adapted to format a transmitted EM signal position into a form transmittable by a transceiver;
and
a transceiver connected to the microprocessor adapted to broadcast the EM signal position directly to another one of said plurality of integrated units mounted in
a vehicle of a second party;
wherein said EM signal is selected from the group consisting of police traffic RADAR, police traffic LADAR, emergency vehicle RADAR, emergency vehicle LADAR, road traffic hazard RADAR and road traffic hazard LADAR.
