  • Publication number: 20240023842
    Abstract: 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.

  • Patent number: 11744348
    Abstract: 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.

  • Patent number: 11589667
    Abstract: A device for ensuring safe operation of a robot used for cosmetics applications, including the retrofitting of robots not originally design for such applications. In some embodiments, the robot is used for the automatic placement of eyelash extensions onto the natural eyelashes of a subject. In some embodiments, a safety barrier is provided by a physical barrier or light curtain. In other embodiments, readily deformable end effectors are used.
