Patents by Inventor Norton W. Bell

Norton W. Bell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of performing measurements and error analysis of the measurements
    Patent number: 4458323
    Abstract: An instrument is disclosed which performs measurements and calculates the average and the variance of the measurements. The particular instrument illustrating the invention is a spectrophotometer which measures sets of dark, reference and sample spectra for use in calculating an average absorbance spectrum and its variance. The measurements are performed in an order which enables the cancellation of measurement variation due to variation in instrument response. The order of measurements is determined by measurement subroutines which can be aggregated to produce a series of measurements performed over a user selected period of integration time.
    Type: Grant
    Filed: March 26, 1982
    Date of Patent: July 3, 1984
    Assignee: Hewlett-Packard Company
    Inventors: Barry G. Willis, Arthur Schleifer, Norton W. Bell, Paul C. Dryden, Andrew Stefanski, C. Nelson Dorny
