  • Inventor(s):
    Tommie L. Wood, Thomas C. Corke, Martiqua Post
    Patent Number:
    US 8308112 B2
    Description:

    An aircraft includes a surface over which an airflow passes. A plasma actuator is configured to generate a plasma above the surface, the plasma coupling a directed momentum into the air surrounding the surface to reduce separation of the airflow from the surface. A method of reducing separation of an airflow from a surface of an aircraft includes generating a plasma in air surrounding the surface at a position where the airflow would separate from the surface in the absence of the plasma.

    Patent Number:
    US 8109050 B2
    Description:

    A floor including a flooring plate and a plurality of spaced apart stiffening columns extending from an underside of the flooring plate. The columns remain substantially rigid up to a predetermined critical pressure and then buckle as the pressure increases. The columns are at least partially surrounded by a resilient underlayment. Deflection stops may extend from the flooring plate to prevent over-buckling and/or permanent deformation of the stiffening columns. In some examples, the deflecti…

    Patent Number:
    US 7744738 B2
    Description:

    The present invention provides a method and apparatus for use in rapid particle transportation, separation, focusing, characterization, and release. Dielectrophoresis and electro-osmotic driven fluid convection are used independently or in tandem as the driving forces for particle manipulation and on occasion characterization. Although dielectrophoresis has been acknowledged for decades as a powerful technique for particle manipulation and characterization, long processing times and measureme…

    Patent Number:
    US 8323349 B2
    Description:

    A bearing surface having increased wear resistance. Generally, certain aspects of the present invention are directed to an implant design based on concepts of unidirectional load application and the use of engineered surfaces to increase the amount of lubricant at the bearing surface, to thereby reduce wear of the bearing surface. Surfaces of certain bearing surface embodiments are fabricated to maximize lubricant retention, encourage lubricant entrainment, and/or restrict lubricant escape fr…

    Patent Number:
    US 7275013 B2
    Description:

    Methods and systems are described for a system for obtaining information regarding a flow. These methods and systems comprise a signal generator configured to generate an alternating current signal at a carrier frequency and a transformer arranged to receive the generated signal, wherein the transformer and carrier frequency are selected so that the generated signal resonates at the carrier frequency. The alternating signal is then used to cause plasma to form across a gap between two electro…
