Publication number: 20240023842Abstract: A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data points to the first subset of simulated reflectance curves to determine a closest fitting one of the simulated reflectance curves. The method includes determining a second subset of simulated reflectance curves for a fine grid based on the closest fitting one of the simulated reflectance curves; determining a peak of absorption and reflection coefficients from the fine grid; and determining an absorption and a reflectance coefficient for the reflectance data points by performing a weighted average of the absorption coefficients and reflection coefficients from the peak.Type: ApplicationFiled: October 3, 2023Publication date: January 25, 2024Inventors: Kate LeeAnn Bechtel, H.

Patent number: 11744348Abstract: A device for automating the process of installing eyelash extensions onto the natural eyelashes of a subject. In some embodiments, the placing of extensions is carried out by a robotic mechanism utilizing computer vision. In some embodiments, the same device may be used for extending eyebrows rather than eyelashes, as eyebrows have rather similar properties to eyelashes.Type: GrantFiled: April 26, 2021Date of Patent: September 5, 2023Assignee: WINK ROBOTICSInventors: Nathan Harding, Kurt Amundson, H. Keith Nishihara, Michael Muller
