  • Publication number: 20140055004
    Abstract: A rotary motor and a method of making the same include a vibrating motor body which has two orthogonal first bending modes and is substantially enclosed within a housing. A shaft is frictionally coupled to the vibrating motor body and is arranged to rotate in at least one direction about a rotation axis in response to the vibrating motor body. The shaft is frictionally coupled the vibrating motor body by a force substantially perpendicular to the rotation axis. One or more bearings support the shaft, are connected to the housing, and define the axis of rotation of the shaft.

  • Patent number: 8646942
    Abstract: A luminaire includes an electrical base, an optic, and a heat sink disposed between the base and the optic. The lens has a first curved portion, a second curved portion and a third portion. An LED light source is coupled to the heat sink with LED modules arranged to direct light in the same direction. A frustoconical member having a reflective outer surface is disposed between the lens and the LED light source wherein the LED light source has LED modules disposed to emit at least a portion of light toward the reflective outer surface such that light is emitted with a substantially even luminous intensity in a 0°-135° zone.

  • Publication number: 20140020912
    Abstract: An apparatus for isolating a first zone from a second zone in a subterranean wellbore. The apparatus includes an outer tubular and an inner tubular disposed within the outer tubular forming an annular flow path therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path that is in fluid communication with the second zone. A sleeve having at least one seal is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path.

  • Patent number: 8466637
    Abstract: A method, computer readable medium, and apparatus for controlling a moveable element includes generating and providing with a control device one or more driving signals to one or more positioning actuators to move the moveable element towards a target position based on a target travel distance and a calibration value. The control device determines when a post-movement position of the moveable element is outside of a tolerance range of the target position. The control device recalibrates the calibration value when the post-movement position is determined to be outside of the tolerance range. The control device repeats the generating, the determining, and the recalibrating as open loop steps until the post-movement position is within the tolerance range or until a limit, if any, on attempts is reached.
