For a complete automation, was build a control panel to visualise technical alarms and intrusions alarms (burglar) and a different panel to monitories the state of the windows and revolving shutter (open/close). The access gates in to the courtyard for people and vehicles are automated. The intrusion alarm is activated through the magnetic and impact sensors (for windows) and the technical alarms are activated through water, gas and smoke detectors. Optionally those two alarms can alarm acoustical and optical or making phone calls to preset numbers.

These new systems, which are now appearing in industrial and consumer electronics, also promise great changes in medicine and health. Until recently, the idea of micro-scale energy harvesting, and collecting miniscule amounts of ambient energy to power electronic systems, was still limited to research proposals and laboratory experiments.Today an increasing number of systems are appearing that take advantage of light, vibrations and other forms of previously wasted environmental energy for applications where providing line power or maintaining batteries is inconvenient. In the industrial world, where sensors gather information from remote equipment and hazardous processes; in consumer electronics, where mobility and convenience are served; and in medical systems, with unique requirements for prosthetics and non-invasive monitoring, energy harvesting is rapidly expanding into new applications.This paper serves as a survey for applications of energy harvesting for ultra low power technology based on various technical papers available in the public domain.

The touch screen HMI Weintek eMT3070a is the user interface in the process command of Siemens PLC, in which the distances and displacement speeds are introduced on the three axes. The interface includes monitoring robotic arm movement but also allows its command by incrementing step by step the motion over axis.

The purpose of this paper is to develop and provide web-based system for the handling and control of remote devices via the Internet. Remote devices are currently the industry or mobile robots [13]. For future product development machine in the factory will be included in the system. This article also discusses the current use of virtual reality tools in the fields of science and engineering education. One programming tool in particular, virtual reality modeling language (VRML) is presented in the light of its applications and capabilities in the development of computer visualization tool for education. One contribution of this paper is to present the software tools and examples that can encourage educators to develop a virtual reality model to improve teaching in their discipline. [12] This paper aims to introduce a software platform, called VALIP where users can build, share, and manipulate 3D content in cooperation with the interaction processes in a 3D context, while participating hardware and software devices can be physical and / or logical distributed and connected together via the Internet. VALIP the integration of virtual laboratories to appropriate partners; therefore, allowing access to all laboratories in any of the partners in the project. VALIP provides advanced laboratory for training and research within robotics and production engineering, and thus, provides a great laboratory facilities with only having to invest a limited amount of resources at the local level to the partner site.

Theinconvenience of the former variant resides in the factthat it shows a fast rising velocity of direct and inversecurrents through thyristors, as well as an energyaccumulation in entrance inductances (coils). Thelatter variant, although the previously describedphenomena no longer appear, shows high tensionvalues on the commutation condensers because ofenergy accumulation in the L – C circuit, thusrequiring supplementary protection measures for thethyristors. This paper presents a variant obtained fromthe combination of the two (fig. 1.), inductance L1limiting the velocity of the current rise, and inductanceL0 makes it possible for the discharging of thecondenser through inverse diodes to be avoided. Fromthe analysis of the proposed inverter, presented in thispaper, the conclusion drawn is the fact that it preventsthe deficiencies noticed in the currently used variants,the next step being the confirmation of these throughthe results obtained after usage.

This is done by programming the PLC ladder diagram language that makes movement on the three axes of the arm by means of stepper motors. Required command console PLC is built with the help of a touch screen HMI Weintek. In the user interface are introduced distances and displacement speeds on the three axes.

So, with help of SCADA interface (Supervisory Control And Data Acquisition) all the process can be monitoring and controlling with the computer help. In the paper an application created with the help of the RTU Tbox equipment is presented, application used for the monitoring of a solar installation for the processing of hot water. The application is located in a mountain area, the solar system being made up of collectors with a surface of 2x16 mp, two 500 liter reservoirs and two heat switches.. It also presents an application for monitoring and control of a production line, made from 16 hydraulic presses, with the help of software SCADA Ethernet Tview. Because the major products realized by beneficiary (hub from auto) get to the export where the customs want a strict monitoring the times of vulcanization, of the temperatures and pressures uses, it is necessary to search the best solutions who permit a production control from computer and who can accomplish some conditions impose.
