Abstract

Dispositivo che prevede mezzi emettitori-ricevitori di segnali infrarossi, e mezzi portatili che si presentano generalmente nella forma di una piastrina di riconoscimento o di una scheda comportante dei circuiti elettronici alimentati a mezzo pile, caratterizzato da mezzi (4, 4a) per l'emissione permanente di un segnale di sveglia infrarosso modulato a frequenza hertziana, e da ciò che il mezzo portatile comporta un circuito di sveglia (l-4; 6-26) sensibile a detto segnale di sveglia per stabilire il collegamento fra la sorgente di alimentazione e i circuiti elettronici di detto mezzo portatile.
