Linda H. Kidder 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).

  • High-volume on-line spectroscopic composition testing of manufactured pharmaceutical dosage units
    Publication number: 20090294673
    Abstract: Disclosed are pharmaceutical dosage unit manufacturing process control apparatus and methods. These can include acquiring a plurality of multi-pixel images of a flow of pharmaceutical dosage units at different wavelengths along an axis that is perpendicular to a direction of the flow of pharmaceutical dosage units, processing the images acquired in the step of acquiring, and providing an indication about the flow of pharmaceutical dosage units based on the step of processing.
    Type: Application
    Filed: July 15, 2008
    Publication date: December 3, 2009
    Inventors: E. Neil Lewis, David J. Strachan, Linda H. Kidder

  • Multi-source spectrometry
    Publication number: 20010052978
    Abstract: A spectrometer that includes an array of illumination sources positioned to illuminate a detection area with a plurality of beams of light. A detector is responsive to the detection area, and a spectroscopic signal output is responsive to relative amounts of light from the beams in different spectral regions received by the detector after interaction with the sample in the detection area.
