2. Electromagnetic interference reduction by dynamic impedance balancing applied to biosensors
INTRODUCTION: Electromagnetic interference caused by electric power lines adversely affects the signals of electronic instruments, especially those with low amplitude levels. This type of interference is known as common-mode interference. There are many methods and architectures used to minimize the influence of this kind of interference on electronic instru

5. Biomedic data visualization on mobile devices / Visualização genérica de sinais e dados biomédicos em dispositivos móveis
The objective of this work is to develop a system for visualization of biomedical signals in a generic way. The proposed system uses the SOA architecture to access data and biomedical signals of patients. The display of signals proposed in this paper proves to be effective for devices with a small screen resolution. The implementation of Web services based o

6. Interface and management framework for systems data bank / Framework para interface e gerenciamento de bancos de dados
The usage of specific databases for certain application does not allow the replacement of database or sharing information with other databases by user, without rebuilding the entire application, turning non-trivial the application of the solutions proposed in the literature. This reduces the interoperability among different suppliers of present biomedical da

9. Atualização de sistema duplicador de pulsos para teste de proteses de valvulas cardiacas / Upgrade of a pulse duplicator system for cardiac valve prostheses evaluation
It has become very frequent the use of mechanic or biological cardiac valve prostheses. These prostheses must be evaluated (in vitro and in vivo tests) in order to be used clinically. The hydrodynamic performance tests are carried out in vitro. The analyses of the test results are very important for the characterizations and classification of a given prosthe

11. Numerical analysis of thermal and electrohydrodynamic effects in travelling-wave dielectrophoretic devices
Travelling-wave dielectrophoretic phenomena involving cell detection and manipulation are very interesting for biomedical and biotechnological applications. However, electrohydrodynamic phenomena may interfere with the action of dielectrophoresis. The main goal of our study is to calculate the interplay of these effects. In so doing, we have been able to go

12. Utilização de wavelets no processamento de sinais EMG
This study proposes an approach to analyze EMG signals using wavelets transformed as a method of signal features extraction. The adopted methodology is based on the study of the aggregated power envelope and the aggregate power spectrum envelope, which are obtained from the distribution of energy of a certain signal, based on the potency of wavelet coefficie
