  • Patent number: 9597833
    Abstract: Wrinkling of thin films is a strain-driven process that enables scalable and low-cost fabrication of periodic micro and nano scale patterns. However, real-world application is limited by the inability of current tools to provide the means for applying large, accurate, and non-equal biaxial strains via a device that can fit within the vacuum chambers that are required for thin film deposition/growth during wrinkling. The present biaxial tensile stage is a compact system that enables one to apply large and accurate non-equal biaxial strains to elastomeric films. It consists of (i) fixtures to clamp and hold films onto the stage, (ii) linear bearings for motion guidance, (iii) integrated actuators for real-time stretch control, (iv) base with kinematic coupling for registration to a metrology system, and (v) the structural frame.

  • Patent number: 8601878
    Abstract: A system (1100) for fatigue testing wind turbine blades (1102) through forced or resonant excitation of the base (1104) of a blade (1102). The system (1100) includes a test stand (1112) and a restoring spring assembly (1120) mounted on the test stand (1112). The restoring spring assembly (1120) includes a primary spring element (1124) that extends outward from the test stand (1112) to a blade mounting plate (1130) configured to receive a base (1104) of blade (1102). During fatigue testing, a supported base (1104) of a blade (1102) may be pivotally mounted to the test stand (1112) via the restoring spring assembly (1120). The system (1100) may include an excitation input assembly (1140) that is interconnected with the blade mounting plate (1130) to selectively apply flapwise, edgewise, and/or pitch excitation forces.

  • Patent number: 8561473
    Abstract: In one embodiment, a force sensor apparatus is provided including a tube portion having a plurality of radial ribs and at least one fiber optic strain gauge positioned over each rib of the plurality of radial ribs. The strain gauges are comprised of a negative thermo-optic coefficient optical fiber material in one embodiment. A proximal end of the tube portion is operably couplable to a shaft of a surgical instrument that is operably couplable to a manipulator arm of a robotic surgical system, and a distal end of the tube portion is proximally couplable to a wrist joint coupled to an end effector. In another embodiment, adjacent fiber optic strain gauges with differing thermal responses are used to solve simultaneous equations in strain and temperature to derive strain while rejecting thermal effects. In yet another embodiment, a thermal shunt shell is over an outer surface of the tube portion. An advantageous surgical instrument having improved temperature compensation is also provided.
