Patents by Inventor Augustine M. URBAS

Augustine M. URBAS has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11826868
    Abstract: Apparatuses and associated methods for polishing side surfaces of fibers. The system includes a fiber loading mechanism for securing a fiber to the apparatus, a polishing mechanism, and a linear motion mechanism for linearly translating one of the polishing mechanism and the fiber for polishing a side surface of the fiber using the polishing mechanism.
    Type: Grant
    Filed: December 12, 2018
    Date of Patent: November 28, 2023
    Assignee: United States of America as represented by the Secretary of the Air Force

  • Patent number: 9835870
    Abstract: Methods and systems for the super-resolution imaging can make visible strongly subwavelength feature sizes (even below 100 nm) in the optical images of biomedical or any nanoscale structures. The main application of the proposed methods and systems is related to label-free imaging where biological or other objects are not stained with fluorescent dye molecules or with fluorophores. This label-free microscopy is more challenging as compared to fluorescent microscopy because of the poor optical contrast of images of objects with subwavelength dimensions. However, these methods and systems are also applicable to fluorescent imaging. Their use is extremely simple, and it is based on application of the microspheres or microcylinders or, alternatively, elastomeric slabs with embedded microspheres or microcylinders to the objects which are deposited on the surfaces covered with thin metallic layers or metallic nanostructures.
