Ray Kurzweil - Scientist, inventor, entrepreneur, author and futurist

ComputerHistory — 20 de setembro de 2009 — [Recorded July 13 2009] Ray Kurzweil is a 21st century polymath. He is a scientist, inventor, entrepreneur, author, visionary and futurist. As a scientist and inventor he has pioneered work in optical character recognition (OCR), speech recognition technology, and electronic keyboard instruments. As an entrepreneur, Kurzweil has founded businesses in the fields of OCR, music synthesis, speech recognition, reading technology, virtual reality and financial investment. He is the author of numerous books on health, artificial intelligence (AI), the technological singularity and futurism. The Kurzweilian version of the future is the inevitable merger of humans and intelligent machines.

Verification of Rogowski Current Transducer’s

Verification of Rogowski Current Transducer’s
Ability to Measure Fast Switching Transients

Abstract - Rogowski current transducers combine a high
bandwidth, an easy to use thin flexible coil, and low insertion
impedance making them an ideal device for measuring pulsed
currents in power electronic applications. Practical verification of
a Rogowski transducer’s ability to measure current transients due
to the fastest MOSFET and IGBT switching requires a calibrated
test facility capable of generating a pulse with a rise time of the
order of a few 10’s ns. A flexible 8-module system has been built
which gives a 2000A peak current with a rise time of 40ns. The
modular approach enables verification for a range of transducer.

Primera Comunicación con el Cosmos en Latinoamérica -PERU-RUSSIA

TVUNI — 26 de agosto de 2009 — El Jueves 20 de Agosto se llevó a cabo el 1er radioenlace en Latinoamérica con el Cosmos. Esta comunicación se llevó a cabo en la Universidad Nacional de Ingeniería del Perú a las 13:32, hora local, y lo cual marcó un hito en la historia de las telecomunicaciones del Perú y Latinoamérica. El radioenlace tuvo una duración de 10 minutos en los cuales el rector de la UNI Mag. Ing. Aurelio Padilla Ríos se comunicó con el comandante ruso de la EEI Gennady Ivanovich Padalka quien tuvo frases de elogio y gratos recuerdos del Perú. TV UNI © 2009. Lima, Perú.
