Abstract: A cementing tool for cementing a casing in a well has an inner mandrel that defines a central flow passage and has at least one fluid port defined through a wall thereof. An outer mandrel is disposed about the inner mandrel and the inner and outer mandrels define an annular space therebetween. The outer mandrel has at least one sealing element affixed thereto. An opening sleeve is positioned in the inner mandrel and is movable from a closed position to an open position in which the fluid port is uncovered. An expansion cone is positioned in the annular space. Fluid pressure applied through the central flow passage, and the fluid port will pass into the annular space and will urge the expansion cone through the annular space which will plastically deform the outer mandrel so that sealing elements affixed to the outer mandrel engage a previously installed casing in the well to seal thereagainst.

Abstract: Eyewear includes a left temple and a right temple. Each of the temples has a cavity sized to receive an audio device such as a BlueTooth transceiver configured to communicate wirelessly with a remote device like a cell phone or a digital sound device. The BlueTooth transceiver may be placed in the cavity of either temple with the other temple cavity covered with a cover plate. An earphone may be connected to the BlueTooth transceiver through a receptacle. The earphone delivers the audible sound to the user's ear. The receptacle of the BlueTooth transceiver to which the earphone connects is also configured to receive the connector from a charger to charge a rechargeable battery in the BlueTooth transceiver. The eyewear may also be configured with cover plates over the cavity in both of the temples or with an audio device in both cavities to provide audible signals to both ears of the user.

Abstract: A system and method for throttling a slave component of a computer system to reduce an overall temperature of the computing system upon receiving a first signal is disclosed. The first signal may be from a master component indicating that a temperature for the master component has exceeded its threshold temperature. The slave component or the master component may be a central processing unit, a graphics memory and controller hub, or a central processing unit memory controller hub. The slave component may send a second signal to indicate that a temperature for the slave component has exceeded its temperature. The master component would then initiate throttling of the master component to reduce the overall temperature of the computing system. The master component may be throttled to a degree less than the slave component. A first component may be designated the master component and the second component may be designated the slave component based on a selection policy.

Abstract: Embodiments of a target-based game and methods of playing the target-based game are herein disclosed. In one embodiment, the target-based game includes a vertically-oriented target platform having a plurality of openings therein. Each opening may be approximately circular in configuration, may vary in size, and may have a backing, or “pocket” to catch one or more game pieces. In one embodiment, the target platform includes one or more suspension means about one or more edges or peripheries thereof for holding the target platform in a vertically-oriented position when attached to a plurality of supporting members. When assembled, the supporting members may form a frame to support the suspension means and/or the target platform. A plurality of game pieces may be used to play a variety of games using the target-based game.

Abstract: Embodiments of the present invention include a lens configured to adapt to varying light conditions. The lens comprises a first layer made of a transparent thermoplastic material and a second layer made of a transparent thermoplastic material. The lens also includes a polarized film and a photochromatic film that adjusts to vary the amount of light that is transmitted through the film in response to the amount of ultraviolet radiation received by the film. The lens is thermoformed to have a selected radius of curvature. Embodiments of the lens disclosed herein are adapted for use with a frame that is configured to receive the lens and position the lens proximate a user's face and eyes.

Abstract: A control system for a subsurface safety valve addresses normal open and closed operation and a failsafe operation if key system components fail. It features a single control line from the surface that splits at the subsurface safety valve and goes to one end of two discrete piston chambers that are aligned and isolated from tubing pressure. The piston in one chamber is larger than in the other and the pistons are connected for tandem movement. Each side of the unbalanced system's piston has a seal mounted to it and another for the rod attached to it that exits the chamber. A jumper line connects the chambers at a point between the seals in each chamber and features a large reservoir. The jumper line is filled with a compressible fluid. Fail safe closure of the valve occurs if any of the four seals fail.

Abstract: Systems for operating one or more sliding sleeve valves in an incremental, step-type fashion between open and closed positions, permitting the valve or valves to be choked to progressively smaller flow areas. The systems of the present invention also permit the valve or valves to be fully closed without having to progress through incremental steps.

Abstract: A tubing pressure insensitive actuator system includes a housing having a bore therein; a force transmitter sealingly moveable within the bore the force transmitter defining with the bore two fluid chambers, one at each longitudinal end of the force transmitter; and at least two seals sealingly positioned between the housing and the force transmitter, one of the seals isolating one end of the force transmitter from tubing pressure and another of the seals isolating another end of the force transmitter from tubing pressure and method.

Abstract: A control system can be used with a single control line to a subsurface safety valve. The operating piston is exposed to the flow tube between two blocks with near identical seals to make the piston insensitive to tubing pressure. A control system seal is carried by the piston in the upper block and a passage between the control system seal and the tubing pressure seal in the upper block communicates to a compressible fluid reservoir in the lower block that is also isolated from tubing pressure by a tubing pressure seal. Movement of the piston compresses the fluid in the reservoir. The reservoir can also include a spring to return the piston and the flow tube to a position to close the valve. A redundant system can be actuated if the primary system fails.

Abstract: An apparatus, system and method including a latching device for displaceably retaining a panel relative to a frame. The latching device includes at least a bolt which is carried on the latching device and is operatively associated with the panel to prevent disengagement of the panel. The latching device includes at least one pressure responsive device operatively coupled to the bolt to retain the bolt in a desired position and release the bolt when a predetermined pressure differential occurs relative to two, generally opposite, sides of the panel or when a pressure decrease occurs on one side of the panel.

Abstract: A computer system having one or more components capable of being in either wake or sleep states includes a power manager and a voltage regulator.

Abstract: Method for specific detection of one or more analytes in a sample. The method includes specifically associating any one or more analytes in the sample with a scattered-light detectable particle, illuminating any particle associated with the analytes with light under conditions which produce scattered light from the particle and in which light scattered from one or more particles can be detected by a human eye with less than 500 times magnification and without electronic amplification. The method also includes detecting the light scattered by any such particles under those conditions as a measure of the presence of the analytes.
