  • Publication number: 20170176740
    Abstract: A microelectromechanical system (MEMS) is comprised of a micromirror attached to a semiconductor device. A stack of inorganic high index materials comprised of titanium oxide, titanium nitride, and titanium is deposited above metal levels within the semiconductor device. Another stack of inorganic high index materials comprised of titanium oxide, titanium nitride, and titanium may be deposited in a continuous or dis-continuous layer within one or more of the dielectric layers. Each stack of high index material films is deposited at a depth and of thickness to achieve a minimum reflectance for the entire film system and to ensure maximum destructive interference at the targeted wavelength range. The high index material stack results in reduced light scattering during operation of the micromirror and improves contrast of the display system.

  • Patent number: 8657036
    Abstract: A tubing shoe is disclosed with a body adapted to be connected to a section of tubing to be emplaced in a wellbore and a nose provided on the body, wherein the nose includes a failure guide structure for controlling break-up of the nose upon being drilled out from inside the nose. The failure guide structure typically controls break up by limiting the maximum size of pieces of the nose broken off upon drill out, for example, by defining weakened areas of the nose which are prone to failure upon drilling. The failure guide structure can include discontinuities such as slots or bores formed or drilled into the outer surface of the nose. The failure guide structure controls the break up of the nose in a consistent and predictable manner, and typically at a predictable stage during the drill-out process.

  • Patent number: 7694733
    Abstract: A centralizer having a body with an inner surface provided with a friction-reducing slider, typically located in an annular recess on the inner surface of the body of the slider, spaced from the ends of the body. The slider can be formed separately from a body of the centralizer and subsequently attached thereto on the inner surface so that it is adapted to bear between the outer surface of the tubing to be centralized and the inner surface of the centralizer. This reduces rotational torque transmitted between the centralizer and the tubing, and assists in maneuvering of the tubular string into the desired position in the well.

  • Publication number: 20060060012
    Abstract: The present invention provides a device that modifies the centrifugal force of a series of weights held at the perimeter of a rotating assembly by creating an acceleration on the weights perpendicular to their circular path of travel in addition to the centripetal force acting on them. By creating an acceleration on each weight perpendicular to its circular path and by timing when to create the acceleration, the net centrifugal force of the weights can be increased along the top of their rotational path and decreased along the bottom of their rotational path thereby producing a sustainable imbalance that can produce a thrust which propels the device in a particular direction. By using numerous weights on the rotating assembly, a smoother continuous force will be produced. In addition, the present invention can be processed, accelerated or decelerated to produce three dimensional controlling force vectors to add stability to its platform.
