1. A study of strain and deformation measurement using the Arduino microcontroller and strain gauges devices
Abstract This paper presents a methodology for the measurement of strain by means of strain-gauges, where the data acquisition is done by using an Arduino Uno board, due to the low-cost and the easy manipulation of this microcontrollers. The measured signal conditioning is performed by means of a Wheatstone Bridge and then discretized by an Analog-Digital Co

2. Circuit of Conditioning of Analogical Signals Programmable for Integrated Systems / Circuito de Condicionamento de Sinais Analógicos Programável para Sistemas Integrados
Em sistemas digitais de medição, circuitos de condicionamento de sinais têm como principal finalidade o ajuste dos sinais analógicos para realização da conversão digital. Para maximização da aplicação de um circuito ou sistema de medição, considerando ainda sua integração em uma única pastilha, esses circuitos têm que ser programáveis, de f

3. Computerized invasive measurement of time-dependent intraocular pressure
Several methods have been described to measure intraocular pressure (IOP) in clinical and research situations. However, the measurement of time varying IOP with high accuracy, mainly in situations that alter corneal properties, has not been reported until now. The present report describes a computerized system capable of recording the transitory variability

5. CONTROLE DE ACELERAÇÃO DE UMA MÁQUINA DE VIBRAÇÃO ELETRODINÂMICA / ACCELERATION CONTROL OF AN ELECTRODYNAMIC VIBRATION MACHINE
This work presents the development of a novel digital acceleration controller for sinusoidal vibration tests using switching-mode AC power source (ACPS) fed electrodynamic vibration machines. The proposed scheme is based on the interaction of two control loops: one for the shaker s acceleration regulation and another for the ACPS output voltage control. A ro
