13. On the evolution of remote laboratories for prototyping digital electronic systems
The design of digital electronic systems for industrial applications can benefit in many ways from the prototyping capabilities of field-programmable gate array (FPGA) platforms. This paper presents three evolutionary releases of an FPGA-based remote laboratory and discusses the didactical and technical motivations behind each release, aiming to reduce the o

15. Experimental and theoretical study of a telemetric dynamic torque meter
This paper presents the development of a dynamic torque meter to be applied to rotating shafts using electronic transduction, strain gage, telemetry and LabView Graphic programming. A mathematical model was developed. The electronic transduction signal is transmitted by digital modulation from a remote transduction unit fixed to a shaft to a base station, se

18. New technique for the implementation of digital demodulation of fiber optic gyroscopes / Implementação de uma nova tecnica para demodulação digital de sinal de giroscopio a fibra optica
Gyroscopes are devices used to measure angular orientation, being extensively employed for guidance, navigation and stabilization. Among the many types of gyroscopes, IFOG (Interferometer Fiber Optic Gyroscope), based on Sagnac effect, is the most interesting solution due to its high sensitivity, resolution, reliability, small size and EMI immunity. The pres

20. Active magnetic bearing applied to a tubular linear induction motor. / Mancal magnético ativo aplicado a um motor de indução linear tubular.
A tubular linear induction motor applied to onshore oil exploitation, named MATÆOS (which is in the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation) was built at Escola Politécnica da Universidade de São Paulo (EPUSP). Its purpose is to directly drive the sucker-rod pump installed in the down hole of the oil well. In continu

21. Arquitetura amplificada: incorporação de dispositivos tecnológicos digitais à arquitetura
This dissertation presents a study about the incorporation of digital devices into architecture, focusing on experiences that, through the use of electronically mediated interactions, can enrich the relation between human beings and architectural space. Until a few decades ago, these devices were relatively disconnected from architecture, but recently there
