INPROX Technology Signs Space Act Agreement with NASA to Develop Advanced Sensor

Breakthrough Technology Provides For Advanced Silicon Carbide Digital Sensor

BOSTON, Mass., February 19, 2008 - INPROX Technology Corporation (ITC), a leading sensor technology company announced today that it has entered into a Space Act Agreement (SAA) with NASA Glenn Research Center to develop advanced silicon carbide (SiC) based position sensors aimed at potential uses in future space flight, turbine engine controls and automotive engine applications.

Silicon carbide electronics are capable of operating in the extreme 600�C (1112�F) range and are poised to aid challenging on-engine, aerospace surface, automotive and energy applications and are recognized as a significant advancement over conventional silicon-based electronics. All of today's conventional electronics must be carefully housed in controlled environments shielded from higher temperatures by cooling, necessitating complicated and often costly thermal management systems and long cable runs between critical sensor systems and the electronics that control them.

"The capability to embed electronics in a device without the need to provide cooling provides a substantial technological advantage for many applications in sensing and control," adds Phil Neudeck, Electronics Engineer and Team Lead for this silicon carbide work sponsored by the Aeronautics Research Mission Directorate at NASA Glenn Research Center.

The rising costs of fuel, both in automotive and aerospace markets and the drive for greater reliability at lower costs has the sensors and electronics market anticipating the capabilities of these next generation SiC electronics and sensors. Future space missions and satellites will certainly have high temperature and radiation hardened requirements and will rely heavily on the breakthroughs of today. The reduction or elimination of these thermal management systems and extended cable runs will aid greatly in lowering weight and costs even in the more traditional commercial aviation markets.

In automotive applications, SiC integrated sensors and electronics are currently being studied for cutting edge engine controls that display improved combustion measurement and control; capabilities directly leading to lower emissions and more fuel efficient vehicles. The automotive community is looking hard at SiC sensors to monitor critical cylinder and exhaust parameters.

Installing sensors directly in the engine cylinder chamber and exhaust system allows monitoring of critical pressures and temperatures, providing feedback which allows for the optimized control of valve timing and fuel control. Controlling the engine cylinder temperature has a large impact on the engine performance; both in the burn rate of fuel and in emissions emitted through the exhaust. Since vehicle engines operate over broad spectrums of power output and ambient conditions, these requirements demand engine control systems that can manipulate operating parameters in order to approach theoretical optimum efficiencies.

Because of high temperatures, today's automotive electronics require remote location from quantities to be measured. This introduces inaccuracies and system complexity. Silicon Carbide electronics offer a potential pathway to more accurate engine monitoring. By more closely coupling operating parameters of cylinder pressure and temperature, exhaust and intake temperatures and mass flows with valve timing, ignition timing, and air/fuel delivery; cleaner, more efficient power production could be attained.

"Silicon carbide is one of the most exciting advances in electronics being developed today. The marriage of SiC electronics, which can remain operational in high temperature, high power, and high radiation environments, enabled with our proprietary digital sensor technology is of great significance to us, our customers and the aerospace and automotive communities at large", said Derek Weber, INPROX Technology President, "Playing this vital role in the development of (SiC) sensors with NASA is a great opportunity and one that we are very proud of".

INPROX Technology looks to be a key supplier of advanced SiC based sensor technology; position, pressure, speed and temperature sensors to the automotive and aerospace communities among others. Under this (SAA), high temperature silicon carbide (SiC) electronics from NASA will be prototyped into ITC's proprietary position sensor technology platform. If proven successful, INPROX Technology intends to continue development for uses in the aerospace, automotive, energy and industrial markets in a diversified solutions based platform designed to solve practical applications.
