Abstract

The present invention relates to a vehicle warning system device that is capable of detecting sirens of approaching emergency vehicles. This device includes a plurality of siren detectors, each siren detector capable of generating status signal at an output of each siren detector when activated by a siren. A plurality of visual indicators and a speaker. A microprocessor having a microprocessor plurality of input, a microprocessor plurality of output and a microprocessor memory, the microprocessor plurality of input connected to each output of the plurality of siren detectors, the microprocessor plurality of output connected both to the speaker and an input of each of the plurality of visual indicators.

Claims

1. A safety warning device comprising:

a. a plurality of siren detectors, each siren detector capable of generating a status signal at an output of each siren detector when activated by a siren;

b. a plurality of visual indicators;

c. a speaker;

d. a microprocessor having a plurality of input, a plurality of output and a memory, the microprocessor'"'"'s plurality of input are connected to each output of the plurality of siren detectors, the microprocessor'"'"'s plurality of output connected to the speaker and an input of each of the plurality of visual indicators;

e. one of the microprocessor plurality of output connected to an electrical switch in a vehicle radio;

f. the microprocessor configured to receive and store the status signal from each of the plurality of siren detectors in the microprocessor memory, the microprocessor further configured to generate a voice indicating signal and visual indicating signals, wherein both the voice indicating signal and the visual indicating signals correspond to the status signal from each of the plurality of siren detectors stored in the microprocessor memory;

g. the microprocessor further configured to generate a signal to turn off the vehicle radio when the microprocessor receives the status signal from at least one of the plurality of siren detectors; and

h. the microprocessor further configured to generate only the visual indicating signals when the microprocessor receives the status signal from at least two of the plurality of siren detectors.
