Abstract
In un dispositivo antifurto combinato all'infrarosso (3,4) ed a microonde (6,7), l'elemento rilevatore a microonde (6,7) viene asservito (19) all'elemento rilevatore all'infrarosso (3,4) così da essere attivato, con conseguente diffusione di microonde nell'ambiente sorvegliato, soltanto quando l'elemento rilevatore all'infrarosso (3,4) emette un segnale di rilevazione suscettibile di indicare la presenza di un intruso nell'ambiente sorvegliato. Vengono così ridotti sia l'assorbimento energetico complessivo del dispositivo antifurto, sia l'inquinamento dell'ambiente sorvegliato da parte delle microonde.(Figura 3).
