  • Publication number: 20200000464
    Abstract: An orthopedic fixation system fuses bone, bones, or bone pieces in a predetermined anatomical position. The orthopedic fixation system includes an implant that transitions between an unconstrained shape and a constrained insertion shape, a drill guide, first and second K-wires, and a cannulated drill bit. The drill guide and the first and second K-wires retain the bone, bones, or bone pieces in an anatomical position corresponding with the predetermined anatomical position. The cannulated drill bit fits over the first and second K-wires and drills, respectively, first and second drilled holes into the bone, bones, or bone pieces. After insertion of the implant into the first and second drilled holes, the implant attempts to transition from its constrained insertion shape to its unconstrained shape such that the implant continuously compresses the bone, bones, or bone pieces thereby holding the bone, bones, or bone pieces in the predetermined anatomical position.

  • Publication number: 20200004330
    Abstract: A system controls a brightness of an augmented reality (AR) eye-mounted device. The system includes an eye-mounted display, a photodetector system, and a controller. The eye-mounted display includes a contact lens and a femtoprojector. The femtoprojector is contained in the contact lens and is configured to project an AR image to a user's retina. The AR image is overlaid on an external scene viewed by the user through the contact lens. The photodetector system detects a brightness level of the external scene. Based on the brightness level of the external scene, the controller adjusts a brightness level of the AR image projected to the user's retina. In some embodiments, the eye-mounted display receives image data defining the AR image and the controller adjusts a bit depth of the image data based on the brightness level of the AR image.

  • Patent number: 10456131
    Abstract: An implant insertion device is adapted for use with a shape memory implant. The shape memory implant includes a bridge interconnecting first and second legs. The shape memory implant is movable between a first shape in which the first and second legs are substantially non-parallel and a second shape in which the first and second legs are substantially parallel. The implant insertion device engages the shape memory implant to maintain the shape memory implant in its second shape until the delivery of the shape memory implant into tissue or bone.

  • Patent number: 10352381
    Abstract: A brake disc for a high performance vehicle comprises a rotor 20 formed of grey cast iron and comprising a friction ring 24 annular about an axis of rotation 26 and, coaxial with the friction ring 24, a tubular flange 28 extending axially from the friction ring 24 to a free end 28a and having a wall 28e with a radially inner face 28c and a radially outer face 28d. A hub 22 formed of aluminum is cast over the flange 28 to encapsulate at least a portion of the wall 28e, with which it has a shrink-fit connection. The encapsulated portion of the wall is made smooth (or otherwise formed with a varying radial dimension, or a screw thread) so as to permit differential thermal contraction, in an axial direction, of the hub 22 relative to the flange 28 as the hub 22 solidifies and cools after its casting. By this means, retained stresses in the hub 22 are minimized.

  • Publication number: 20190053793
    Abstract: An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may include one or more needles. The suture passer may also include a pusher; a distal end with a sharp, blade-like extension; or a side-loading distal end.

  • Publication number: 20180149884
    Abstract: An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.

  • Patent number: 9572566
    Abstract: An implant manipulator may have a distal end that retains an implant, a proximal end, and an intermediate portion between the ends. The intermediate portion may have a cross-sectional shape that extends along a nonlinear pathway. The intermediate portion may have a selectively bendable portion in which the cross-sectional shape varies to facilitate bending when desired. The implant manipulator may be a needle for a suture passer, with a suture capture feature at the distal end. The suture capture feature may have first and second members that flex apart to permit entry of the suture into a suture capture hole wherein the suture is retained until released. A suture passer may receive the needle in a bore shaped to change the cross-sectional shape to facilitate or restrict bending of the needle, as needed.

  • Patent number: 8959431
    Abstract: Architecture generates low resolution placeholder content that preserves the usefulness of application responsiveness by preserving and displaying the structure of the content. This facilitates decreased memory requirements associated with pre-rendering structurally-intact content. The architecture enables the storing of pre-rendered content at a lower zoom level than is intended for actual display to require fewer resources, pre-rendering content at a lower zoom level to allow the application to adjust for the lower zoom level to provide more structural integrity than would be achieved rendering at full display zoom level and compressing the resulting data, stretching the pre-rendered content to the zoom level that is intended for display in order to achieve a low resolution appearance that merges directly with the full resolution content, and transitioning between low resolution content and full resolution content when the full resolution content becomes available.

  • Patent number: 7934026
    Abstract: A method to preserve a logical communication path in a data processing system, that includes a host computer, a storage controller that comprises a first logical control unit (“LCU”), and a logical communication path that is in communication with the host computer and the first LCU, comprising deleting the first LCU and setting a first status for same. The method then configures a second LCU, and establishes a second status for same, wherein the second LCU includes all or a portion of the first LCU, but is not the same as the first LCU. The deleting, setting, configuring, and establishing are performed while maintaining the logical communication path, which is in communication with the second LCU.
