Established high-performance containment design concept.
Conducted CFD modeling to speed design optimization.
Completed schlieren visualization testing to confirm capture and containment.
U.S. Patent 6,089,970 issued for the basic concept; U.S. Patent 6,428,408 issued for the advanced “air divider“ technique and other features (see Fig. 4).
Conducted ASHRAE Standard 110-1995 test and achieved containment with 70 percent flow reduction using alpha prototype.
Established partnerships with laboratory hood and controls manufacturers to develop and test alpha units.
Signed intellectual property agreement for product development in the microelectronics field.
Conducting new field tests in 2002 with larger version; started additional field test in 2001; completed two field tests in 2001.
Designed new lighting systems that reduce lighting energy by 47 percent, improve lighting quality and reliability while reducing maintenance.
