  • Publication number: 20170015007
    Abstract: An apparatus for driving an articulating probe comprises an elongate probe constructed and arranged to articulate in at least one predetermined degree of motion and to transition from a flexible state to a rigid state, and a force transfer mechanism constructed and arranged to apply a force to the probe. The force is selected from the group consisting of a force that causes probe to articulate in the at least one predetermined degree of motion and a force that causes the probe to transition from the flexible state to the rigid state. The base structure is attached to portion of the force transfer mechanism and the elongate probe; the base structure comprising one or more stabilizing elements constructed and arranged to resist undesired movement of the probe caused by force from the force transfer mechanism.

  • Patent number: 7246524
    Abstract: The present invention comprises a novel, lightweight, massively parallel device comprising microelectromechanical (MEMS) fluidic actuators, to reconfigure the profile, of a surface. Each microfluidic actuator comprises an independent bladder that can act as both a sensor and an actuator. A MEMS sensor, and a MEMS valve within each microfluidic actuator, operate cooperatively to monitor the fluid within each bladder, and regulate the flow of the fluid entering and exiting each bladder. When adjacently spaced in a array, microfluidic actuators can create arbitrary surface profiles in response to a change in the operating environment of the surface. In an embodiment of the invention, the profile of an airfoil is controlled by independent extension and contraction of a plurality of actuators, that operate to displace a compliant cover.
