  • Patent number: 10813791
    Abstract: A method for modifying a refractive property of ocular tissue in an eye by creating at least one optically-modified gradient index (GRIN) layer in the corneal stroma and/or the crystalline by continuously scanning a continuous stream of laser pulses having a focal volume from a laser having a known average power along a continuous line having a smoothly changing refractive index within the tissue, and varying either or both of the scan speed and the laser average power during the scan. The method may further involve determining a desired vision correction adjustment, and determining a position, number, and design parameters of gradient index (GRIN) layers to be created within the ocular tissue to provide the desired vision correction.

  • Patent number: 10806567
    Abstract: A method for modifying the refractive index of an optical, polymeric material. The method comprises irradiating select regions of the optical, polymeric material with a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000 nJ. The irradiation results in the formation of refractive optical structures, which exhibit little or no scattering loss. The method can he used to modify the refractive index of an intraocular lens following the surgical implantation of the intraocular lens in a human eye. The invention is also directed to an optical device comprising refractive optical structures, which exhibit little or no scattering loss and are characterized by a positive change in refractive index.

  • Publication number: 20200323460
    Abstract: A system and method for rehabilitation and recovery using adaptive surface electromyographic sensing and visualization is disclosed. The system uses surface electromyography (sEMG) sensors to identify signals of intent from patients with physical disabilities and then uses these signals to interact with a computer system designed to create repetitive practice In a manner that promotes neurological recovery. A machine teaming module analyses body signals picked up during patient movement attempts and converts these body signals to a visual representation of the intended movement by way of a virtual body or virtual body part displayed on a computer display, display glasses, or the like. The system thus allows for very early patient therapy, providing early benefits to rehabilitation therapy not heretofore possible. The virtual reality or augmented reality environment provides a patient with very early visual reinforcement of beneficial muscle activation patterns.

  • Patent number: 10772496
    Abstract: A method for imaging retinal structures involves offsetting an imaging aperture from the center of the reflected/scattered light distribution. Images are obtained with the imaging aperture at multiple offsets with respect to the center. The various obtained images are co-registered to a reference confocal image in a reference wavelength and averaged to generate high signal to noise ratio images. The images may be combined in various ways to enhance the contrast of retinal structures that would not be visible in confocal images.

  • Patent number: 10739111
    Abstract: Digital cloaking is a method for practical cloaking, where space, angle, spectrum and phase are discretized. At the sacrifice of spatial resolution, a good approximation to an ideal cloak can be achieved—a cloak that is omnidirectional, broadband, and operational for the visible spectrum, three-dimensional (3D), and phase-matching for the light field, among other attributes. One example of a digital cloak is an active cloak that uses lenticular lenses, similar to integral imaging for 3D displays. With the continuing improvement in commercial digital technology, the resolution limitations of a digital cloak may be minimized, and a wearable cloak can be implemented.

  • Publication number: 20200229890
    Abstract: A surgical visualization and medical imaging device and related computer based imaging methods and systems are disclosed. The surgical devices of the present invention use indocyanine green dye combined with a plastic, and are used in enhanced surgical imaging in applications such as robotically assisted surgeries. A near infrared light source, such as an 805 nm laser, may be used to excite the surgical device so that the device emits 835 nm light. Both the excitation and emission wavelengths penetrate tissue and blood, and provide enhanced imaging of surgical procedures. The resulting fluorescence image allows a user to readily determine relative tissue depth, to identify tissue inhomogeneity, to detect masses or tissue irregularities, to pinpoint anatomical holes, and to visualize tears.

  • Patent number: 10646154
    Abstract: A system to assess risk of changes to brain white matter includes a sensor system adapted to measure an energy of each impact to an individual belonging to a sub-population that causes a repetitive head impact (RHI). A head impact dose equivalent number (HIDEN) process calculates a HIDEN for a most recent RHI event based on the energy of the most recent RHI event, a time of the most recent RHI, and all previously recorded RHI events available in a non-volatile memory. A sub-population function process calculates a risk assessment number based on the sub-population and the HIDEN. A risk assessment notification means provides a notification of the risk assessment number. A method to assess risk of changes to brain white matter based on a head impact dose equivalent number and a method to define a sub-population function to convert a HIDEN to a risk assessment value is also described.
