Title: The Innovations of Karl Norris
Introduction
Karl Norris is an accomplished inventor based in Beltsville, MD (US). He has made significant contributions to the field of spectrophotometry, particularly in the measurement of protein content in whole grain samples. With a total of two patents to his name, Norris continues to push the boundaries of innovation in his field.
Latest Patents
Norris's latest patents include a method for measuring the percentage of protein in whole grain samples using a near-infrared spectrophotometer. This method involves making reflectance measurements at wavelengths shorter than 1600 nanometers, which correspond to absorbance bands of the sample's constituents. The absorbance data is normalized by subtracting the absorbance value at a first wavelength and dividing the resulting data by the value at a second wavelength. This process allows for accurate determination of protein content in unknown samples based on regression coefficients derived from known samples.
Another notable patent is for a spectrophotometric instrument that features rapid scanning distortion correction. This instrument addresses distortion caused by the rapid scanning of the spectrum. It utilizes photodetectors to detect light energy, which is scanned at a rapid rate. The output signal from the photodetectors is amplified, sampled, and converted to digital values. By determining the first derivative from these digital values and applying a correction constant, the instrument provides a set of corrected values that accurately represent the intensity detected.
