The electronic block collects the alarm signals form diverse sensors like humidity, gas or fire sensors and transmits the alarm signal through an alarm sound system, telephone or GSM network.; Sistemul inteligent de securizare, alarma si control reprezinta un bloc autonom ce se alimenteaza de la acumulator. Blocul electronic efectueaza colectarea semnalelor de alarma de la diversi senzori de umiditate, gaze, incendiu, spargere si efectueaza transmiterea semnalului de alarma prin sistem de alarma sonor, înstiintare prin reteaua telefonica sau GSM. The intelligent security, alarm and control system represents an autonomous block which uses an accumulator as power supply. The electronic block collects the alarm signals form diverse sensors like humidity, gas or fire sensors and transmits the alarm signal through an alarm sound system, telephone or GSM network.

It was demonstrated that the absorption is 3000 times more intense at E||c polarization than it is at E┴c polarization. The device permits to separate the optical TE and TM modes in optoelectronic devices.; Dispozitivul este elaborat în baza cristalelor CuGaS2 cu anizotropie optica la absorbtie si reflexie la temperatura de 300 si 10K. A fost demonstrat ca absorbtia este de 3000 ori mai intensa în cazul polarizarii E||c decât în cazul polarizarii E┴c, ce permite separarea modelor optice TE si TM în dispozitive optoelectronice.
