  • Patent number: 9993159
    Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) light sources for early detection and monitoring of breast cancer, as well as other kinds of cancers may detect decreases in lipid content and increases in collagen content, possibly with a shift in the collagen peak wavelengths and changes in spectral features associated with hemoglobin and water content as well. Wavelength ranges between 1000-1400 nm and 1600-1800 nm may permit relatively high penetration depths because they fall within local minima of water absorption, scattering loss decreases with increasing wavelength, and they have characteristic signatures corresponding to overtone and combination bands from chemical bonds of interest, such as hydrocarbons. Broadband light sources and detectors permit spectroscopy in transmission, reflection, and/or diffuse optical tomography. High signal-to-noise ratio may be achieved using a fiber-based super-continuum light source.

  • Patent number: 9500635
    Abstract: A system and method for using near-infrared or short-wave infrared (SWIR) sources such as lamps, thermal sources, LED's, laser diodes, super-luminescent laser diodes, and super-continuum light sources for early detection of dental caries measure transmission and/or reflectance. In the SWIR wavelength range, solid, intact teeth may have a low reflectance or high transmission with very few spectral features while a carious region exhibits more scattering, so the reflectance increases in amplitude. The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools. The measurement device may communicate with a smart phone or tablet, which may transmit a related signal to the cloud, where additional value-added services are performed.

  • Patent number: 9494567
    Abstract: Non-invasive monitoring of blood constituents such as glucose, ketones, or hemoglobin A1c may be accomplished using near-infrared or short-wave infrared (SWIR) light sources through absorbance, diffuse reflection, or transmission spectroscopy. As an example, hydro-carbon related substances such as glucose or ketones have distinct spectral features in the SWIR between approximately 1500 and 2500 nm. An SWIR super-continuum laser based on laser diodes and fiber optics may be used as the light source for the non-invasive monitoring. Light may be transmitted or reflected through a tooth, since an intact tooth and its enamel and dentine may be nearly transparent in the SWIR. Blood constituents or analytes within the capillaries in the dental pulp may be detected. The non-invasive monitoring device may communicate with a device such as a smart phone or tablet, which may transmit a signal related to the measurement to the cloud with cloud-based value-added services.
