Government-Owned Inventions; Availability for Licensing and 
Cooperative Research and Development Agreements (CRADAs)

AGENCY: Centers for Disease Control and Prevention, Technology Transfer 
Office, Department of Health and Human Services.

ACTION: Notice.


SUMMARY: The invention named in this notice is owned by agencies of the 
United States Government and is available for licensing in the United 
States (U.S.) in accordance with 35 U.S.C. 207, and is available for 
cooperative research and development agreements (CRADAs) in accordance 
with 15 U.S.C. 3710a, to achieve expeditious commercialization of 
results of federally funded research and development. A provisional 
patent application has been filed. In addition, the invention is 
protected by copyright registration. A Patent Cooperation Treaty (PCT) 
application and national stage foreign patent applications claiming 
priority to the Patent Cooperation Treaty (PCT) application are 
expected to be filed within the appropriate deadlines to extend market 
coverage for U.S. companies and may also be available for licensing.

ADDRESSES: Licensing and CRADA information, and information related to 
the technology listed below, may be obtained by writing to Suzanne 
Seavello Shope, J.D., Technology Licensing and Marketing Scientist, 
Technology Transfer Office, Centers for Disease Control and Prevention 
(CDC), Mailstop K-79, 4770 Buford Highway, Atlanta, GA 30341, telephone 
(770)488-8613; facsimile (770)488-8615; or e-mail [email protected]. A

Computer Software for Automating Permeation Testing Data Analysis

    Data analysis for chemical protective clothing (CPC) permeation 
testing involves a number of equations and experimental factors. 
Experimenter bias and possible calculation errors are critical issues 
when determining permeation parameters. In order to compare results 
among different laboratories and manufacturers, the normalized 
breakthrough time is required since it is not dependent on the 
detection limits of the analytical system. However, calculating the 
normalized breakthrough time requires the use of polynomial curve 
fitting, polynomial derivatives, and quadratic equations. Solving these 
equations, without a computer program, would be very difficult. 
Therefore, a unique computer program using Microsoft Visual C++, 
referred to as ``Permeation Calculator'', has been developed at the 
National Institute for Occupational Safety and Health/National Personal 
Protective Technology Laboratory (NIOSH/NPPTL) to calculate the 
permeation parameters. The program imports data and then calculates the 
permeation parameters;

including breakthrough detection time, ASTM normalized breakthrough 
time, European normalized breakthrough time, and steady-state 
permeation rate. The calculation of these parameters is based on a 
series of strategies, approaches, and algorithms. At the end, the 
program displays all the permeation parameters as a report file that 
can be saved as a Microsoft Excel file or a text file. The program 
reduces the time spent on data analysis from hours to seconds.
