The paper presents a designed, implemented and tested application intended to evaluate the level of attention to people who perform activities that require a high level of concentration, using a measurement system in one point of the electroencephalographic signal. The paper presents the hardware and software structure that highlights the advantages of the system.
World of industry in this moment doesn't offer possibility to have unlimited time for maintenance. When a breakage it is happen, in a limited time you need to solve the problems. In this article we are proposing a solution for a good management of accidental maintenance. Our solution is a little module that can be interchanged in a system when the breakage of this appear. The module that we propose...
The paper presents the study regarding the implementation of actuators that use special smart material springs. The system relates to an actuator formed by of two elements, one fixed and one mobile that are attached to a force measuring device. Between the two elements are placed a number of springs made from a material with special properties, and those springs heated at different temperatures will...
World became a place where the human is not the principal generator of working force. In nowadays engineers created almost all industries fully automated, where the people are only supervising the production. All this industry that is highly automated had become dependent for the spare parts and maintenance. When it's appearing a problem in a highly automated industry it may be possible a halt in...
In this paper is presented the authors concern regarding the development of solutions in the field of heliothermic actuators achieved based on the solid heat medium. One of the research directions has led to an actuator with bimetallic band in the form of flat spiral spring and heat conductive fins. In the end of the paper are presented main conclusions regarding the tests made on the actuator with...
In this paper we present a solution to save electrical components and energy in a system that produces compressed air. This system has a couple of compressors and when are connected to one tank these compressors work unsynchronized. Our solution reduces the number of start-ups for each one and minimalizes the cost of maintenance.
This paper presents a study on the implementation of the nitinol motor that use springs with shape memory. It refers to an engine system with two eccentric rings systems, which are attached to each other with the nitinol elements. While they are immersed in hot water they will give forces that will result a rotative motion. The operating characteristics are presented, materialized in the spring force...
CEUS figure are actually a series of images that captures the ferrofluid spectrum movement under the action of a rotating magnetic field. Depending on the shape of the field pattern, the ferrofluid located inside a cylindrical dielectric recipient, gets a rotating movement that is highlighted by a bronze powder cluttered on the surface of it. This paper presents the results obtained from the modeling...
This paper presents the software application, performed in LabView, concerning the utilization of clock hour number transformation diagram for the three-phase transformers. The transformation diagram through its configuration and composition expresses all the possibilities of amending clock hour number, by changing connections to the transformer terminals. The end of the paper presents the conclusions...
