Recognizing the need for additional safety precautions in the railway system, Indranil Majumdar of India was awarded the $100,000 worldwide top prize for developing the Railway Collision Avoidance System 2001, or RACAS.
RACAS is an anti-collision system that prevents collisions in a railway network.
It uses paired digital transponders operating in the ISM for radio ranging and quasi-packet connectivity.
Andrew Matykin of Russia used TI's high-performance analogue products to design an Ultrasonic Binaural Radar System for the blind that received top prize for the European region.
The system is intended to aid the blind to better orient themselves relative to their environment and the objects that surround them.
The system allows a person to determine the disposition of objects in a space through audible signals based upon changing frequency and the phase shift of reflected acoustic waves.
Matykin's design included a variety of instrumentation and signal amplifiers, audio power amplifiers, power management and interface products for TI.
The top prize for the Americas region went to Kwokon Ng of the USA.
Ng designed wireless electronic equipment for the sport of fencing.
In the lightning-fast sport of fencing, electronic equipment is used extensively to detect hits and misses.
Currently, bulky cable reels and floor cables are expensive and require high levels of maintenance.
This new wireless system uses an ISM band to replace the cables while remaining compatible with the standard weapons and body-cords.
Ng's design used a number of data convertor/codec, comparator, logic, RF, microcontroller and DSP products, all from TI, in his winning design.
