Abstract

"PROCESSO E DISPOSITIVO PARA DETECTAR OBJETOS LOCALIZADOS SOBRE UM PáRA-BRISA". Dispositivo e processo para detectar objetos (3) em um pára-brisa (2). O processo compreende as seguintes etapas: registro de um segmento do pára-brisa (2) pelo lado interno através de uma matriz de sensores ópticos (4), focalizada no lado externo (7) do pára-brisa (2), a qual apresenta uma multiplicidade de elementos de imagem individuiais; apuração dos espectros de frequência local S (f) das oscilações de intensidade de elementos de imagem reunidos em um ou vários blocos da matriz de sensores (4) e em seguida a análise dos espectros de frequência local, em que os espectros de frequência local apurados S(f) são comparados com uma ou várias distribuições de frequência de referência e em que é gerado um sinal para controlar um ou vários atuadores quando ocorre uma conformidade suficiente dos espectros de frequência local S(f) com uma distribuição de frequência de referência. O dispositivo compreende uma unidade de detecção (4) conectada à um módulo computador (5), a qual constitui uma matriz de sensores (4) provida de um diaframa (9) e está alojada a uma certa distância atrás do pára-brisa (2).
