Abstract

''SISTEMA PARA AVISO DE INCIDENTES DE TRáFEGO''. Sistema para aviso de incidentes de tráfego, especialmente a aproximação de veículos de emergência, compreendendo um transmissor de rádio adaptado para ser posicionado em um primeiro veículo, por exemplo, um veículo de emergência, e um receptor de rádio adaptado para ser posicionado em um segundo veículo. O mencionado transmissor é adaptado para emitir pulsos de freq³ência de rádio dentro de uma faixa de freq³ência escolhida, a intervalos escolhidos sendo substancialmente mais longos do que a duração dos pulsos, e o mencionado receptor é adaptado para receber sinais de rádio dentro da mencionada faixa de freq³ência escolhida e detectar a ocorrência dos mencionados pulsos, o receptor compreendendo também meios para indicar visual ou audivelmente a detecção dos mencionados sinais.
