  • GRIN lens structure in micro-LED devices
    Patent number: 11275202
    Abstract: A GaN layer of micro-LEDs is exposed to ion implantation to amorphize one or more regions of the GaN layer. As a result, the GaN layer through which light rays propagate have non-uniform refractive indexes that modify propagation paths of some light rays. Ions are implanted in a region overlapping an active region that emits light to function as a converging GRIN (gradient-index) lens. The ion implanted regions collimate light rays that propagate along predetermined directions. As such, the light extraction from and the focus of the micro-LEDs is increased.

  • Method, device, and computer program for virtually adjusting a spectacle frame
    Patent number: 11262597
    Abstract: A virtual try-on process for spectacles includes an approximate positioning and a fine positioning of a spectacle frame on a head of a user. Provided for this purpose are 3D models of the head and the spectacle frame, as well as head metadata based on the model of the head and frame metadata based on the model of the frame. The head metadata contains placement information, in particular a placement point, which can be used for the approximate positioning of the spectacle frame on the head, and/or a placement region which describes a region of the earpiece part of the frame for placement on the ears of the head. A rapid and relatively simple computational positioning of the spectacle frame on the head and a more accurate positioning using a subsequent precise adjustment can be achieved with the aid of the metadata.

  • Weekly and monthly disposable water gradient contact lenses
    Patent number: 11256003
    Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.
