Abstract
A traffic warning system for first responders, such as the police, firefighters, and paramedics, that allows a first responder to wirelessly communicate their pending approach to an intersection with a multimedia warning system mounted and hardwired to a conventional traffic light and operated via an integrated remote control device or mobile phone application (“mobile app”) using radio frequencies, BLUETOOTH® technology, wireless digital technology, or the like.
Claims19
A traffic warning system, comprising:
- a warning system housing including module display windows and an integrated radio frequency receiver;
- a transmitter for each of two or more first responders, each transmitter configured to transmit a signal to the radio frequency receiver for alerting motorists and pedestrians of emergencies at intersections, wherein the radio frequency receiver and each transmitter operates in the VHF or UHF radio spectrum within frequency bandwidths allocated for emergency public service communications by the Federal Communications Commission;
- a coding scheme and frequency for the transmitter of each first responder communicating wirelessly with the radio frequency receiver, wherein the coding scheme includes a digital code address and a prefix for each first responder;
- an encryption code and frequencies using a rolling code, frequency-hopping spread spectrum method, transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies avoiding interference, preventing eavesdropping, and enabling code-division multiple access;
- and
- a local area computer network, a wide area computer network, or a combination of networks facilitating transmission and receipt of commands associated with operation of the traffic warning system.

A traffic warning system, comprising:
- a warning system housing including glare resistant LCD digital technology signage monitor screens, an integrated radio frequency receiver, wherein the radio frequency receiver operates in VHF or UHF radio spectrum within frequency bandwidths allocated for emergency public service communications by the Federal Communications Commission;
- content that can display a graphic Fresnel lens texture on the monitor screens to enable the monitor screens to be controlled by a timer;
- a coding scheme and frequency for each first responder communicating wirelessly for emergencies for alerting motorists and pedestrians;
- a digital code address and a prefix for each first responder;
- a transmitter;
- a local area computer network, wide area computer network, or a combination of networks facilitating transmission and receipt of commands associated with operation of the traffic warning system;
- an encryption code and frequencies using a rolling code, frequency-hopping spread spectrum method and transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies avoiding interference preventing eavesdropping, and to enable code-division multiple access.
