2. Developement of an ecg telemetric system powered by photovoltaic cells for hyperbaric chambers / Desenvolvimento de sistema telemÃtrico passivo alimentado por cÃlulas fotovoltaicas para aquisiÃÃo de ecg em cÃmaras hiperbÃricas
This dissertation presents the development of a Passive Telemetry system for ECG measurement inside of a hyperbaric chamber. Hyperbaric Chambers are used to oxygenotherapy treatments, where an enviroment with 100% of O2 is applied at 3 atm. To avoid risk of ignition and fire, the internal circuitry must be low voltage and very low power, so a passive telemet

3. Projeto e desenvolvimento de um sistema multicanal de biotelemetria para detecção de sinais ECG, EEG e EMG / Design and development of a multichannel biotelemetry system for ECG, EEG and EMG signal acquisition
O emprego de novas técnicas na aquisição, processamento e análise de sinais bioelétricos, têm contribuído significativamente para o melhoramento dos processos de monitoramento fisiológico de indivíduos. Porém, em muitas situações deseja-se registrar aqueles sinais concomitantemente com monitoração e execução de movimentos livres, como durante

4. Design and development of a multichannel biotelemetry system for ECG, EEG and EMG signal acquisition / Projeto e desenvolvimento de um sistema multicanal de biotelemetria para detecÃÃo de sinais ECG, EEG e EMG
The application of new techniques for data acquisition, processing and analysis of bioelectrical signals has contributed to the improvement of physiological monitoring. However, in some circumstances, it is necessary to record those data during complex activities, such as running and jumping. Conventional monitoring relies on devices that require a set of ca

5. Desenvolvimento de um medidor de fase para um sistema de biotelemetria passiva / Development of a phase meter for a passive biotelemetry system
This work describes the development of a phase measurement equipment for use in a passive biotelemetric system, whose system and measurement technique were developed before in the Biotelemetry Laboratory of the UTFPR. Based on a new technique and phase measurement system developed in this work it was possible to implement an equipment to measure the input ph

6. Cardiovascular responses to locomotor activity and feeding in unrestrained three-toed sloths, Bradypus variegatus
Heart rate (HR) and systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure were recorded by biotelemetry in nine conscious unrestrained sloths for 1 min every 15 min over a 24-h period. The animals were allowed to freely move in an acoustically isolated and temperature-controlled (24 ± 1ºC) experimental room with light-dark cycle (12/12 h). Behavior

7. Biotel3M : sistema de biotelemetria multicanal para a monitoração da marcha
Most eletromedical devices for monitoring and measuring physiological parameters of human locomotion do not allow free movement, which causes discomfort to the individual as well as compromising the veracity of the collected data. The objective of this work is to design an equipment based on biotelemetry technology which would give greater freedom of movemen

8. Desenvolvimento de sistemas bio-telemétricos para a medida da freqüencia cardíaca e do ritmo respiratório. / Development of Biotelemetric systems for the measure of the cardiac frequency and the respiratory rhythm.
O desenvolvimento da Física tem possibilitado sua atuação em vários campos, e mais recentemente, na Medicina, onde estudos da Freqüência Cardíaca e do Ritmo Respiratório fornecem informações importantes acerca de processos fisiológicos e podem ser um útil instrumento diagnóstico e terapêutico. Nestes estudos, em muitos casos, necessita-se que a

9. Cardiovascular responses induced in free-moving rats by immune cytokines.
1. We investigated the effect of intraperitoneal (I.P.) injections of the immune cytokines, interleukin-1 beta (IL-1 beta) and tumour necrosis factor (TNF) on cardiovascular responses in free-moving rats, using a biotelemetry system. 2. The I.P. injection of a small dose of IL-1 beta (1 microgram/kg) induced a monophasic increase in the heart rate, and that
