MEI
has extensive computer and software capabilities for engineering
design and analysis. The latest in computer aided design tools are
used to maximize productivity and reduce development time. The CHEMKIN
chemical kinetics software, developed at Sandia National Laboratories,
provides modeling of chemical systems and catalytic reactions. For
mechanical design layout, MEI uses AutoCAD R14 and SolidWorks and
a variety of translation programs to interface with other CAD packages.
For detailed thermal and structural analysis, COSMOS/M finite element
code is used, which is capable of non-linear stress, vibration,
and heat transfer analyses. For electronic design and layout, OrCAD
and PADS-2000 and P-CAD codes are used. PHOENICS 3-D computational
fluid dynamics code provides flow analysis, which is suitable for
modeling complex laminar, turbulent, two-phase flows, and reacting
flows. |

MEI’s
electronics fabrication area include soldering/desoldering stations,
wirebonders, optical microscopes for product inspection, ultrasonic
cleaning stations, a thick film screen printer for the fabrication
of heaters, temperature sensors and hybrid circuits and a dicing
saw to separate microsensors in a wafer. In addition, a machine
shop equipped a CNC mill, a CNC lathe, and a variety of tools provide
for the fabrication of protective enclosures, manifolds, and other
auxiliary product components. |

MEI
test laboratories include a variety of electronic test equipment.
Incorporated in the lab are oscilloscopes, multimeters, power supplies,
as well as thermal and flow instrumentation including electronic
pressure transducers, thermocouple probes, flowmeters and high-pressure
gas and liquid handling equipment which are used for research projects.
A gas reactor panel with close loop temperature control of the reactor
bed supports the development of chemical reactors. MEI also has
two Tracor gas chromatographs, one dedicated to reactor research
and the other dedicated to sensor development. |

MEI
has extensive data acquisition capability using multifunction PC
I/O boards. MEI uses LabView, LabWindows, and the Borland Delphi
development environments for writing data acquisition and control
software. Extensive C tools are available for customization of the
software. Two Sun Systems closed-loop environmental chambers are
used for in-house thermal evaluation of equipment from -55 to 125°C.
Two VWR vacuum ovens, equipped with deep vacuum pumps and automated
gas filling systems are used to characterize the effect of temperature
and pressure on sensor output, while exposing it to various gas
concentrations. |
