This paper deals with some of the virtual instruments we achieved in order to study the d. c. circuits and the resistance measurement methods. These are effectively used in teaching and learning activities where they turned out to be very helpful for the students. We made them simple, easy to use and intuitive, being an alternative, more flexible, method of practice in the laboratories. [ABSTRACT FROM AUTHOR]

The processes located in the environments such as the underground mining, mineral oil or natural gases, chemical processes are subject to risk factors like explosions, fires, contamination with gas or toxic substances. Monitoring and prediction of both environment and equipments parameters from these processes represent a priority in conditions because by the maintaining of these parameters in correct limits and taken actions at the right time depends: preventions of humans, technological or environment accidents, assurance the microclimate conditions for humans in respective works. This requires data collection through data acquisition systems, comparing them with accurate and possibly setting limits on the values of measurements and predictions of its dangerous. In this paper we propose a system structure of a data acquisition and data processing procedure for obtaining a prediction on the evolution of the measured values. [ABSTRACT FROM AUTHOR]

The paper presents the actuation system of an electromagnetic element whose control is developed in LabView. The actuation is performed when the entered code is identical to the previously stored one. If someone enters another code, the circuit blocks. [ABSTRACT FROM AUTHOR]

This paper presents a virtual instrument built in LabVIEW used like a software solution to implement an angular speed measurement for a mobile that is moving in a circular direction. For this, first is determined the function through which is possible to detect the direction of movement and this is implemented through the graphical programming language used in LabVIEW.

In this paper a solutions for data acquisition and processing from the displacement resistive sensors is proposed. For these displacement sensors, is used a DC potentiometric bridge whose output signal is a voltage that has the amplitude dependent of resistance variation namely displacement value and polarity dependent of displacement direction.
