Abstract

Patente de Invenção: <B>"DISPOSITIVO PARA ATIVAçãO E/OU DESATIVAçãO DE DISPOSITIVO DE SEGURANçA"<D>. A invenção consiste em um dispositivo para ativação e/ou desativação de um dispositivo de segurança, especialmente de um dispositivo de entrada para um veículo, com uma unidade emissora portátil para envio sem fios de uma informação codificada, que é recebida por um dispositivo de recepção e que é comparada com uma informação codificada previamente definida, e no caso de ambas as informações coincidirem é emitido pelo dispositivo de recepção um sinal de comando para o dispositivo de segurança sendo que a unidade emissora e o dispositivo de recepção podem ser avançados em relação à informação codificada atual. Dispositivo, no qual uma desativação não autorizada do dispositivo é evitada de forma segura, em que se realiza um avanço de n vezes na unidade emissora (1) e no dispositivo receptor (2) a seguir a um espaço de tempo previamente definido, em que o espaço de tempo previamente definido é apenas ligeiramente maior, do que o tempo decorrido do sinal portador da informação codificada da unidade emissora ao dispositivo receptor com um alcance máximo do dispositivo receptor.
