  • Artificial tessellated implants, and systems and methods of making and using same
    Patent number: 11771563
    Abstract: A synthetic material can comprise a plurality of rigid components. Each rigid component can be spaced from each adjacent rigid component to define respective interstices between each rigid component and each adjacent rigid component. A flexible material can be disposed within each respective interstice and can extend between and connect to adjacent rigid components.
    Type: Grant
    Filed: January 3, 2020
    Date of Patent: October 3, 2023
    Assignee: UNIVERSITY OF ALASKA ANCHORAGE
    Inventors: Cheryl Wilga, Evelina Natekin, Matthew Calhoun, Petra Ditsche, Raghu Srinivasan
  • Suction device for reversible adhesion to a substrate surface
    Patent number: 11286974
    Abstract: A suction device, in particular a suction cup, suction lifter, or vacuum gripper, for reversible attachment to a substrate surface, comprising a first component, which is used for the actuation of the suction device, and a second component, which can be brought into contact with the substrate surface via the suction cup surface, wherein the first component consists of at least one harder first material and the second component of at least one, in comparison to the first material, softer second material, wherein the second material is an extremely soft material with a Shore 00 hardness less than 50, wherein the thickness of the second component measures, in an unloaded condition, at least 2.5% of an outer diameter or a length or a width of the first component and/or particles and/or fibers, which are harder than the second material, are integrated into at least one second material.
