Abstract

Patente de Invenção: "PROCESSO PARA DETERMINAçãO DA DISTANCIA ENTRE DOIS DISPOSITIVOS DE UM SISTEMA DE IDENTIFICAçãO". Trata-se de um processo para determinação da distância entre dois dispositivos de um sistema de identificação, em que o primeiro dos dispositivos envia um sinal eletromagnético que é formado por uma seq³ência de oscilações com uma evolução de amplitude previamente indicada e uma duração previamente indicada, cuja amplitude se reduz de forma constante em direção ao fim da seq³ência de oscilações. O sinal é captado e é medida a duração da parte que ultrapassa um valor de limiar de amplitude previamente indicado do sinal recebido. A partir desta duração medida determina-se a distância entre os dispositivos.Patent of Invention: "Process for Determining the Distance Between Two Devices of an Identification System". It is a process for determining the distance between two devices of an identification system, wherein the first device sends an electromagnetic signal which is formed by a sequence of oscillations with a previously indicated amplitude evolution and a previously indicated duration, whose amplitude decreases steadily towards the end of the oscillation sequence. The signal is captured and the duration of the part exceeding a previously indicated amplitude threshold value of the received signal is measured. From this measured duration the distance between the devices is determined.
