RESUMO
In this study, we presented an experiment to obtain the thermal relaxation time which is necessary to model heat conduction by the hyperbolic heat equation. This experiment was evaluated by finite element simulation to acquire reliably this parameter for biological tissue. Besides that, we measured the thermal relaxation time of agar-gelled water with 2% of concentration at 25°C. The average value of thermal relaxation time for the gel was 7.9630s with standard deviation of 1.4562.

A system for remote monitoring of patients' vital signs using multipoint videoconferencing is proposed. A multiparametric module and a videoconference server were developed to set up a proof-of-concept where a text was streamed live as data was captured, while a third party monitored it.

In this work, a system to transfer electrocardiogram image signal through videoconference is described. The approach proposed was tested in order to evaluate its performance and the quality of the signal received back from the videoconference. The performance presented good results as the system react rapidly and no losses of data were observed.
