  • Patent number: 11096574
    Abstract: An apparatus for producing a fundus image includes: a processor and a memory; an illumination component including a light source; a camera; and a display, the memory stores instructions that, when executed by the processor, cause the apparatus to: display a target element on the display; display a light source reflection from a cornea of an eye on the display; update a position of the light source reflection on the display as a caregiver manipulates a position of the apparatus relative to the eye; as time elapses, modify the display to allow the light source reflection to more easily be positioned within the target element; and automatically initiate fundus image capture with the camera when the light source reflection is within the target element on the display.

  • Patent number: 11039795
    Abstract: A method of estimating oxygen saturation includes illuminating a target site with light of three different wavelengths, for example green, red and infrared, and detecting light returned from the site at each of the wavelengths. The method distinguishes between cardiac pulsatility and nonpulsatility based on a parameter of the return light of the shortest wavelength. The method formulates an estimate of oxygen saturation as a function of a parameter of the light of the two longer wavelengths taken at both a period of pulsatility and at a period of nonpulsatility. An oximeter adapted to carry out the method is also disclosed. Aspects of the method and oximeter may be used to estimate other physiological parameters.
