Optoelectronic Module For Gas Detection DOROGAN, V.; VIERU, S.; VIERU, T.; DOROGAN, A.; SECRIERU, V.; MUNTEANU, E.; BALICA, Ş.; KAPON, E.; SÎRBU, A. Optical gas detection module consists of vertical emitting laser diode (VCSEL), optical flux control photodiode, a thermoelectric cooler, thermo-resistor - all integrated in one chip. The gas chamber consists of a parallel mirrors system. Optical beam is multiply reflected in the mirror system after it is recorded by a photo-detector. Optical path of beam in the gas medium is changed by the rotation of mirrors that reflect the optical beam, increasing the absorbed energy by the gas. Pending.

Monitoring And Remote Control System DOROGAN, V.; VIERU, S.; VIERU, T.; SECRIERU, V.; MUNTEANU, E.; BALICA, Ş. The monitoring and remote control system is an autonomous unit, which is powered from the accumulator. The electronic block collects signals from various sensors of humidity, gas, fire, breaking and transmits signals via a stationary phone or GSM. Battery supply systems are carried out by the conversion of renewable energy (hydro, wind, solar). Pending. Exibits Clasification: Class no. 10 Information Technology and Communication

Optical Modes Separator (Te, Tm) Based On In0.3Ga0.7As/GaAs Heterostructures With Quantum Wells SÎRBU, N.; DOROGAN, A.; VIERU, T.; KAPON, E.; MEREUŢA, A. The study of luminescence, absorption and reflection spectra of In0.3Ga0.7As/GaAs heterostructures with quantum wells was made for determining fundamental electronic states of polariton excitons in quantum wells. The presence of electronic transitions from the excited excitonic states was determined and it was proposed a model of optical modes separator (TE, TM) based on In0.3Ga0.7As/GaAs heterostructures.

Intelligent system for the fabrication of glass-coated microwires ZAPOROJAN, S.; CALMÎCOV, I.; PLOTNIC, C.; LARIN, V.; PAVEL, V. Unlike a conventional casting plant, the proposed system is based on the technologies of machine vision and assures video monitoring of microwires’ casting for the optimization of technological process. The realized control model offers a mechanism to estimate on-line the geometry of the metal-filled capillary and predict the evolution of the process of microwire casting. Pending.
