William C. Karl 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).

  • Publication number: 20130130926

  • Patent number: 8247240
    Abstract: Performing high-resolution determination of the relative shift of the spectral properties of a biosensor. The shift in the resonance peak of the biosensor is indicative of the amount of material bound to the surface of the biosensor. A preferred biosensor is a Guided Mode Resonant Filter Biosensor (GMRFB). In one aspect of the invention, curve fitting is used to determine the relative location of the spectrum of the unexposed biosensor with respect to those spectra that are altered (e.g., shifted) by the presence of materials bound to the surface of the biosensor. In an alternative embodiment, the cross correlation function is used to detect spectral peak offsets between a reference spectrum and a spectrum measured from an exposed biosensor. In yet another alternative, maximal likelihood estimation techniques are used to determine the spectral shift or offs.

  • Patent number: 7689017
    Abstract: In one aspect, the invention is a method to reduce a blooming effect of a bright object in a medical image generated from a low-dose imaging system. The method includes characterizing an ideal image as a composition of a first component and a second component. The first component is characterized by a first function and the second component is characterized by a second function. The method also includes minimizing the first function and the second function using a smoothing process and generating the medical image based on the minimizing.
