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.'' SYSTEM FOR WARNING OF TRAFFIC INCIDENTS ''. System for warning of traffic incidents, especially the approach of emergency vehicles, comprising a radio transmitter adapted to be positioned in a first vehicle, for example, an emergency vehicle, and a radio receiver adapted to be positioned in a second vehicle. Said transmitter is adapted to emit radio frequency pulses within a chosen frequency range, at chosen intervals being substantially longer than the duration of the pulses, and said receiver is adapted to receive radio signals within said frequency range. chosen frequency and to detect the occurrence of said pulses, the receiver also comprising means to visually or audibly indicate the detection of said signals.
