A Wireless System for Monitoring the Progressive Loading of Lower Limb in Post-Traumatic Rehabilitation

F. Neaga; Daniel Moga; Dorin Petreus; Mihai Munteanu; Nicoleta Stroia

The paper presents a low cost system for wireless monitoring of the progressive loading of lower limb. This system contains a smart device able to measure the plantar pressure, to compare it with predefined levels and to signal the patient in order to avoid excessive loading of the limb in case of patients following post-traumatic rehabilitation.

Model based approach in fault detection and diagnosis for DC motor

Petru Dobra; Mirela Trusca; Ioan-Valentin Sita; Radu Munteanu; Mihai Munteanu

Recent advances in microelectronic circuit have enabled the application of process diagnostics to a variety of systems to improve performances and the reliability. Failure detection and isolation strategies monitor a system for degradations and if detected, classify the failure source. One of the most important methods for failure detection and diagnosis is the analysis of the variations of the estimated parameter of DC Motor. In this paper is presented a structure of a method for failure detection and diagnosis based on continuous time parameter estimation of a mathematical model of the DC Motor. Continuous time parameters can be related easily to the physical characterizations of DC Motor. The parameter is directly estimated by well-known prediction error method of identification for dynamic systems. The failure detection it is based on changing the process coefficient and statistical decision methods. Unlike usual papers, the failure can be detected whether others process parameters are not constant.

Didactic Application for Monitoring Biomedical Parameters and Data Transfer over the Network Using Virtual Instrumentation

Radu Munteanu; C. Mureşan; Dan Iudean; Mihai Munteanu; B. Amza

Telemedicine is used on a large scale for monitoring the state of a patient and permits the real-time contact between the doctor and the patient. The software applications and the TCP/IP protocols, combined with the data acquisition techniques, allow the doctors and engineers to cooperate towards reliable medical equipment and solutions.

EMG Signals Case Study: A Time and Frequency Domain Analysis

Mihai Munteanu; Corneliu Rusu; Daniel Moga; Rozica Moga; G. Tont

The paper aims to analyze the time and frequency domains of EMG signals coming from healthy patients and from patients with muscular disorders (muscular myopathy and neuropathy). The study of these signals can reveal some features in time domain or in frequency domain, that can serve as a basis for diagnosis.

Hand prosthesis simulation developped in the virtual instrumentation technique

Dragos Ploscariu; Mihai Munteanu; Rozica Moga; Constantin Pica

The present study proposes an artificial upper limb prosthesis simulation that combines elements of electric engineering (sensors, data acquisition / transfer, servo-motors) and virtual instruments programming technique (LabVIEW). Since we are in the process of working on a prototype of the prosthesis, the paper presents a model that enables the movement of a single phalanx, operated by a LabVIEW program. This program controls the servo-motor rotation, by using the data acquired by the Arduino board.

Numerical modelling of a wind farm located in the south area of Romania through equivalent electrical circuits

Denisa Stet; Dan Ovidiu Micu; Andrei Ceclan; Levente Czumbil; Mihai Munteanu; Mihaela Cretu; Anca Nicu

Unexpected faults occurring in certain conditions on renewable energy sources connected to the power grid may result in severe damages, if capacitive load exists and consequently inductive power factor correction is applied with shunt coils. The paper presents some investigations on a case study.

Examples of undergraduate students projects in the area of assistive technologies

Laura Grindei; Dan Mandru; Mihai Munteanu; Vasile Topa; Tony Ward

Within the SALEIE project LLP Programme 527877-LLP-1-2012-“Strategic Alignment of Electrical and Information Engineering in European Higher Education Institutions”, work package 4 is concerned with Widening Participation & Student Support. As an integral part of this work package, consideration is to be given to how students with disabilities can be supported throughout their studies within the electrical and information engineering (EIE) disciplines. An important result of this project will be the on-line Student Support Centre, which is planned to include a technical resource area on undergraduate student projects in the field of designing and using assistive technologies. The purpose of this paper is to present several examples of projects at undergraduate level, undertaken in the area of assistive technologies by students from the Technical University of Cluj-Napoca, Romania.

Structured Light Based Imaging Architecture for Guided Fracture Reduction

F. Neaga; I. Raus; Rozica Moga; Daniel Moga; S. Vlad; Nicoleta Stroia; Mihai Munteanu

This paper introduces a structured light based imaging architecture able to serve for the development of an affordable guided fracture reduction system. The 3D models of the bones in the healthy limb are used for the preoperative alignment of the proximal and distal segments of the fractured bone using algorithm for automated registration. A structured light setup performs the reconstruction of 3D information needed for the intraoperative guidance in order to support the fracture reduction in accord with the preoperative alignment.

Application of Virtual Instrumentation for Transmitting and Processing ECG Signals

Mihai Munteanu; P. Bechet; Corneliu Rusu; D. D. Micu; Radu Munteanu; Rozica Moga; C. Amza

The paper aims to emphasize the possibilities offered by Virtual Instrumentation (LabVIEW) in the field of biomedical engineering. Thus, it proposes a low cost and flexible wireless transmission (between two equipments) and ECG signals processing architecture. Since during acquisition the signal may be corrupted by noise, in the first stage of the application the signal is filtered by implementing a designed mean averaged filter, followed by a Butterworth filter. The second stage of the application is represented by the infrared transmission of the signal between two infrared “in range” compatible devices. Finally, for an accurate R-peak detection, the Pan-Tomkins algorithm was implemented.
