I am a brazilian retired Electronic Engineer (BS in 1970 by Instituto Tecnologico de Aeronautica - ITA). I was expert in Analog Electronic , Digital Electronic, Switched Energy Power Supply and Microchip microcontrollers. I initiated my profession in telecommunication area (Empresa Brasileira de Telecomunicaçoes - EMBRATEL from 1971 until 1984). After that I founded with 3 more mates a company (SKY DIGITAL) that dealed with control systems for automation of transportation belts. By 1995 I went out from that company and acted as design engineer developing medical instruments for sonotherapy. By 1999 I got a retirement but followed designing instruments to be used with fiber optics. My last project was a fiber optic interface to transmit high quality audio signal to be distributed inside a shopping center with very low delay to avoid echo.
