  • Publication number: 20240148291
    Abstract: An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared.

  • Patent number: 11977027
    Abstract: A method and device for determining the depth and fluorophore concentration of a fluorophore concentration below the surface of an optically absorbing and scattering medium suitable for use in fluorescence-based surgical guidance such as in tumor resection is described. Long-wavelength stimulus light us used to obtain deep tissue penetration. Recovery of depth is performed by fitting measured modulation amplitudes for each spatial frequency to precomputed modulation amplitudes in a table of modulation amplitudes indexed by optical parameters and depth.

  • Patent number: 11866669
    Abstract: A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber are controlled by controlling the moisture in the combustion atmosphere and energy injections at or downstream of the combustion chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy plasma within the combustion chamber environment are controlled to degrade hazardous polyfluoro compounds.

  • Patent number: 10966800
    Abstract: Two-piece bilateral illumination attachment for dental camera is a light source that is reversibly attachable to any dental camera. Two-piece bilateral illumination attachment for dental camera has two light sources that directly face each other. When properly attached to a dental camera, two-piece bilateral illumination attachment for dental camera effectuates sub-enamel illumination or bilateral illumination of a tooth, so that the dental camera may capture a photo or image of the illuminated tooth. Two-piece bilateral illumination attachment for dental camera has a specially shaped body that makes a slip-fit, press-fit, or snap-fit onto the exterior surface of any dental camera. Two-piece bilateral illumination attachment for dental camera has a distal section and a proximal section. The distal section is reversibly attachable to the proximal section.

  • Patent number: 10364400
    Abstract: A process of making a fuel product from spent grain from a beer brewing process. In the brewing process, the grain is pulverized to a particle size whose mean particle size is approximately 0.25 mm to 0.6 mm with less than 1% greater than 2 mm. After the brewing sugars are extracted from the grain, the spent grain is pressed against a filter to reduce moisture below sixty-five percent (65%), and then the grain is dried to further reduce its moisture to less than ten percent (10%). The dried spent grain, after the aforementioned processing, is fed into a combustion chamber for a steam boiler that is used for beer brewing, and the spent grain is separated during combustion by agitation such as spraying of the grain in the combustion chamber.

  • Patent number: 9447354
    Abstract: A process of making a fuel product from spent grain from a beer brewing process. In the brewing process, the grain is pulverized to a particle size whose mean particle size is generally in the range of 0.25 mm to 0.6 mm with less than 1% greater than 2 mm. After the brewing sugars are extracted from the grain, the spent grain is pressed against a filter to reduce moisture below sixty-five percent (65%), and then the grain is dried to further reduce its moisture to less than ten percent (10%). The dried spent grain, after the aforementioned processing, is fed into a combustion chamber for a steam boiler that is used for beer brewing, and the spent grain is advanced downward through the combustion chamber with agitation to aid combustion.
