August 2003 - The General Atomics-led team of GA, MTECH, and Oak Ridge National Lab (ORNL) has successfully completed a comprehensive study of the benefits of applying low-temperature power electronics systems to ship-board power systems. The GA/MTECH/ORNL, or GMO, study was funded by the Defense Advanced Research Projects and dealt with optimizing all the factors that impact the losses, size, and weight of a complete motor controller for a large-scale all-electric vessel. The performance of synchronous rectifiers, converters, and inverters at reduced temperatures were evaluated, and MTECH's proprietary technologies were applied to further enhance the system's performance.
DARPA Study of SiGE Diodes at Low Temperatures
March 2003 - MTECH has collaborated with GPD Optoelectronics in a DARPA-funded program. In this project, GPD and MTECH investigated silicon-germanium devices for use in cryogenic power electronic systems. MTECH's role in the project was to test at low temperatures SiGe diodes fabricated by GPD, measuring such factors as reverse recovery and current-voltage characteristics. MTECH evaluated a shipboard motor drive utilizing SiGe devices rather than silicon components.
Telecommunications Traffic Analysis Completed
August 2002 - MTECH has completed a mathematical analysis of telecommunications traffic for a Texas-based telecommunications firm. Using this analysis, MTECH has developed C++ based algorithms, which were implemented by the company to upgrade their product line.
Neonatal Imaging Isolette Developed
July 2002 - MTECH has collaborated with researchers at a prominent medical school to develop an isolette for use in functional imaging of neonates.
MDA Phase II SBIR Awarded
May 2002 - MTECH has been awarded the second phase of the MDA SBIR program completed in January 2002. The project involves the development of cryogenic power electronics components, and will culminate in the fabrication and testing of cryogenic power inverters.
