摘要： An anchoring module capable of being secured within a structure includes at least one compliant ring configured to radially expand and an expandable device positioned within the compliant ring to expand the compliant ring from a relaxed state to interface with the structure. The anchoring module is part of a modular system used to harvest fluid, such as oil or natural gas from a structure, such as a pipe or well. Another module of the system, sometimes referred to as a support or back-up module, employs an expandable surface that is capable of expanding to the diameter of the interior of the borehole. These modules may be combined in a variety of configurations to support a sealing element, such as an inflatable sealing element. The self-conforming nature of the system obviates the need for prior knowledge of the structure or complex sensor systems to chart the structure. The anchoring module can also be utilized in a crawling system to convey tools inside a structure.

摘要： A compliant mechanism is provided for accurate and precision alignment of mechanical component parts, surfaces or assemblies and the like, where low-cost, accurate, and repeatable alignment are desired. The compliant mechanism may be used in applications that require high precision alignment and where the relative location of coupled components must be variable or adjustable. The compliant mechanism includes a stage coupled to a plurality of hinges, at least one tab coupled to one of the hinges, and a support coupled to the tab. The relative position of the stage and the support may be adjusted by actuating (i.e., displacing) the tab(s) or other parts of the structure, to enable controlled movement in six degrees of freedom therebetween.

摘要： The invention includes a surgical fastener and associated deployment system and method that overcomes the drawbacks of prior art surgical mesh fixation devices. The surgical fastener and deployment system may be used to fixate a surgical mesh material to the abdominal wall for the purpose of hernia repair. In accordance with one embodiment, the fastener may include an anchor head comprising a bi-pyramid framework. The anchor head is preferably made from a highly deformable and biocompatible material that withstands high flexural strain within an oscillatory environment. The anchor head may be provided in an elongate, undeployed configuration, and then expanded during deployment into a second, generally planar configuration. The anchor head may be biased to expand into the generally planar configuration from the undeployed configuration in a variety of manners.

摘要： A high-bandwidth MEMS actuation system includes actuator pairs coupled in parallel to a stage, each actuator energizable in a drive direction against a bias to an energized position, and movable upon deenergization, to the rest position to define an actuation cycle. The actuators are asymmetric, with an energization frequency greater than a bias frequency, and are opposably coupled to one another. A pulse generator alternately transmits pulses to the actuators, at an alternation frequency greater than the bias frequency. The pulse generator transmits the energization pulses to each of the actuator pairs sequentially at a sequence frequency greater than the cycle frequency. The actuators are each movable from energized to rest positions faster than the bias frequency, and the actuator pairs are sequentially energizable faster than the cycle frequency, wherein the stage is movable in one degree of freedom at a bandwidth of at least four times the cycle frequency.

摘要： A MEMS actuator includes a coil stack in the form of microfabricated, electrically conductive first and second superposed layers. A magnet array is superposed in magnetic communication with the coil stack, with first and second coils being selectively, electrically actuatable to generate relative movement between the coil stack and the magnet array both in-plane and out-of-plane. In various embodiments, a plurality of the actuators are integrally coupled to a microfabricated compliant mechanism to provide a high bandwidth, six degree of freedom nanopositioner.

摘要： A micro electro-mechanical system (MEMS) positioner, including an actuator and method for making the same, includes a stage formed within a first layer of semiconductor material, along with a series of beams, flexure hinges and controlled input thermal actuators. The actuators are operatively engaged with a second layer, and are selectively actuatable to effect longitudinal expansion thereof, so that relative actuation between individual ones of actuators spaced in the planar direction relative to one another is configured to generate controlled movement of the stage within the planar direction, and relative actuation between individual ones of actuators spaced orthogonally to the planar direction relative to one another is configured to generate controlled movement of the stage out of the planar direction. The relative position between the stage and the support is adjustable in each of six degrees of freedom, so that the compliant mechanism forms a quasi-static precision manipulator.
