  • Patent number: 11759194
    Abstract: Systems and methods are provided for illumination of the periorbital exterior of the eye and the interior of the eye with a non-invasive (or non-penetrating), trans-corneal, trans-conjunctival, trans-scleral, non-incandescent, and/or low-temperature light source. In some examples a ring structure is configured to sit on a surface area of an eye, the ring structure having a top surface and a bottom surface, wherein the bottom surface is configured to touch the eye. A plurality of light-emitting elements is configured in the ring structure and a plurality of apertures is configured on the bottom surface of the ring structure, wherein the plurality of light-emitting elements is aligned with the plurality of apertures.

  • Publication number: 20200187601
    Abstract: Systems, methods, and computer-readable storage media for applying an adhesive film to the sole of shoes. Application of a portion of the adhesive film can be performed by receiving a shoe on top of the adhesive film, which in turn is above a plate and compressible pins. Upon receiving the shoe, the plate is raised or lowered, and the compressible pins mark the perimeter of the sole of the shoe. The adhesive film is cut in a sole-shaped pattern due to the height differentiation, resulting in a sole-shaped portion of the adhesive film being adhered to the sole of the shoe.
