  • Publication number: 20190357769
    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: 10413179
    Abstract: A fundus imaging system is used to generate fundus images when a patient has not received mydriatic pharmaceuticals. The fundus imaging system includes a processor and memory, an infrared light source, and an image sensor array. The infrared light source illuminates the patient's fundus using only infrared light. The fundus imaging system uses one or more different near-infrared wavelengths to illuminate the patient's fundus, and the fundus imaging system captures images during infrared light illumination. Then the fundus imaging system generates a color image of the patient's eye fundus based on generated lightness maps of the infrared-illuminated images.

  • Patent number: 10376141
    Abstract: A fundus imaging system includes: an image sensor array, where the image sensor array includes monochrome photodiodes and global shutter control, an illumination unit with one or more light-emitting diodes that have one or more dies, a computing system including a processor and memory, one or more lenses, one or more reflective mirrors, and a display. In an example method of use, a clinician positions a patient, initiates a focal adjustment, initiates a retinal imaging process, and the same or a different clinician views the image. In some embodiments, the imaging system is configured to analyze the image and identify detected physical attributes in the image relating to the diagnosis and treatment of diabetic retinopathy.

  • Patent number: 10229298
    Abstract: An antenna system may include a first metamaterial antenna having a first resonant frequency and a second metamaterial antenna having a second resonant frequency. The first resonant frequency may be different from the second resonant frequency. A first feed point may be connected to the first metamaterial antenna, and a second feed point may be connected to the second metamaterial antenna. A signal may be applied to the first and second feed points so that the first and second metamaterial antennas radiates electromagnetic energy while the signal is being applied and so that the antenna system is configured to send or receive signals over both the first and second resonant frequency bands.

  • Publication number: 20190038124
    Abstract: A system automatically captures a fundus image with limited user interaction such that the fundus image has one or more desired characteristics. The system can retrieve at least one image from an image capture device, process the at least one image digitally to generate a processed image, detect at least one point of interest in the processed image, determine that each of the at least one point of interest is representative of a corresponding feature of the eye, and obtain a fundus image of the eye based on the at least one image.
