    Proceedings of the 2016 International Conference and Exposition on Electrical and Power Engineering EPE 2016, 2016
    The paper mainly deals with the assessment of the general public exposure to low frequency magnetic fields in a complex urban area of the Iasi city, Romania. More than 150 measurements have been taken indoor, in three apartments, and outdoor, at 23 locations in the vicinity of a power substation and along a street route. All measured exposure levels, also including those recorded in the proximity of a number of household appliances, are well below the ICNIRP reference level.
  • Ultrasonic radar
    Marius Valerian Paulet, Andrei Salceanu, Oana Maria Neacsu
    Proceedings of the 2016 International Conference and Exposition on Electrical and Power Engineering EPE 2016, 2016
    The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the sensor produced for Arduino with the microcontroller PIC 18F, manufactured by Microchip. We have taken into account the temperature influence on the ultrasound. The radar can detect objects located at distances between 2 cm and 4 meters and displays the value of distance to the object. The object detection is performed inside an angle of 180 degrees. The motion sensor that covers this angle uses a stepper motor. Data are presented on a LCD display, the motor movement being synchronized with the browsing of the radar screen. Synchronization is made by programming the timers of the microcontroller. These timers generate interruptions at preset moments, correlated with the completion of a specific area of the graphic display.
  • Assessing the close field non-ionizing emissions of PC-monitors

    Proceedings of the 2016 International Conference and Exposition on Electrical and Power Engineering EPE 2016, 2016
    In recent years there has been an increase in the general concerns regarding the possible negative effects of non-ionizing electromagnetic emissions. A very common situation is determined by electric and magnetic emissions of computer monitors with which we work more than 8 hours a day. This display is located within small distance (around 50 cm) of the most sensitive organs of the human: the brain and eyes. That is the reason that the legal provisions of newly issued EU Directive 35 are completing some earlier rules, which were included in the so-called “TCO certification”. For instance, various synchronizing oscillators and switching power supply units are sources for low frequency electric and magnetic fields. It is no coincidence that the spectrum analyzer NF 5035, used by us for the measurements here reported, has preset from the design, a frequency band called TCO, a different band being dedicated to old CRT monitors and a third, to the currently all-over spread LCD monitors made in TFT technology. We have developed and applied a trustful methodology for measuring E&H field emissions of 4 types of monitors, representative for different generations. We have presented the situations when there were exceedances, issuing explanations and recommendations for control and reduction. Results and metrics were reported for cumulative, simultaneous exposure to many working displays.
  • Expanding the functionality of an EMF spectrum analyzer with self-performed near field probes

    EPE 2014 Proceedings of the 2014 International Conference and Exposition on Electrical and Power Engineering, 2014
    The paper presents the constructive solutions applied for the fabrication of three loop magnetic probes, followed by the affordable calibrating procedures. The performance factors obtained after these processes (edited as .csv format, each one associated with the corresponding calibration graph) were used in association with SPECTRAN NF-5035 capabilities, the selected option (from the main menu) for the sensor being “analog”. The main advantage is that we can identify the emissive points in narrow environments, where it is impossible to place the already integrated, included sensors of the analyzer. Due to the usage of an exterior directional loop probe, it is more intuitive to establish the location of the emissive points. There are demonstrated some advantages of using cheap, self-performed probes, enhanced by means of all the processing facilities offered by a handheld, cunning low frequency spectrum analyzer and its associated software.
  • Virtual device for recovering the hand functions
    Marius Valerian Paulet, Oana Maria Neacsu, Alexandru Salceanu
    EPE 2014 Proceedings of the 2014 International Conference and Exposition on Electrical and Power Engineering, 2014
    The paper presents an affordable, but genuine smart device, as a versatile, complementary tool, that might be use in specialized therapeutic units or even at home. It is an important advantage, considering that most of the already developed devices can work only inside specialized institutes, as they require special operating conditions and qualified personnel. Essentially, it is a common joystick connected to a computer via USB port and software developed in LabVIEW. The system offers fast feedback, based on commands operated in real time. There were developed two versions of software: one for single hand, 2D, asynchronous movements; the other was developed for 3D exercises, synchronously performed with both hands. There are presented the block diagrams and the front panels. The software generates “handy” reports in Word or Excel format. The therapist and also the patient can see the number and quality of performed exercises, (completely or just partially done) and the corresponding necessary time, aiming to remotely evaluate the results. It is possible to transmit (or just post) the exercise-reports on the Internet. By simple knowing the address of the patient's computer, the therapist can evaluate the achieved results and modify (if necessary) the therapeutic course. It is achievable for any authorized person to change or just to improve the data base associated with the recovery exercises. Further developments of the system in order to support two joysticks or a steering wheel and two foot pedals (for many other synchronization exercises) are achievable.

    EPE 2014 Proceedings of the 2014 International Conference and Exposition on Electrical and Power Engineering, 2014
    Research in recent years have led to the emergence of technologies for remote monitoring of patients with the wireless transmitted to biomedical signal obtained from various sensors. Specialist person who monitors can be connected via a router to the IP address of the wireless board monitoring system, and through software developed in LabVIEW graphical programming software can read the value of measuring of the value, but very important is that it can be viewed as biomedical signal monitored.

    With increasing speed Internet developed infrastructure, opportunity for virtual: meetings, training or teambuilding events online. The virtual environments have allowed developing virtual laboratories for study. In these virtual classrooms there experiments can be realized using hardware device or simulate some experiments using different specialized software. Also, students can study theoretical concepts of the application. Clear advantage of online training is their minimum use of resources.
