20130315136 | FRAME TIMING SYNCRHONIZATION IN A GEOSTATIONARY SATELLITE SYSTEM - Aspects of the invention provide a system and method to allow inroute frame timing synchronization without the aid of hub signal loopback or satellite ephemeris data. Furthermore, it allows tracking and compensating of the satellite motion to allow multiple remotes to use TDMA on the inroute frequencies, while minimizing the aperture.

20140355594 | VIRTUAL DATA FRAMING FOR DATA PACKET TRANSMISSION OVER CHANNELS OF A COMMUNICATIONS NETWORK - An approach for transmission of data packets, based on virtual frame timing, over a communications channel is provided. A remote terminal receives a first stream of data packets at periodic time intervals. The terminal receives an allocation of time slots within a sequence of TDMA transmission frames, for transmission of the data packets over the channel. The timing structure of the allocated time slots is based on a virtual frame size relative to the interval timing of the first data packet stream, and independent of the frame size/timing of the TDMA transmission frames. The remote terminal may receive a second stream of data packets at periodic time intervals that differ from the time intervals of the first stream. In a multi-stream scenario, the virtual frame size for the time slot allocation is based on the greatest common denominator of the interval timings of the first and second data streams. | 12-04-2014 |

20110083857 | REPEATABLE, COMPRESSION SET DOWNHOLE BYPASS VALVE - A bypass valve for use in tubing string which can be repeatedly opened and closed to selectively provide bypass fluid flow between the interior of the tubing string and the annulus to assist in flowing debris. The valve uses hardened valve elements which can be opened and closed while flowing fluids under pressure through the tubing string. The valve is actuated by placing the tubing string in a sufficient weight down condition to operate the valve. A trigger is provided to prevent unintended actuation of the bypass valve during use. | 04-14-2011 |
20110203809 | WELLBORE BYPASS TOOL AND RELATED METHODS OF USE - Disclosed is a bypass tool for connection in a tubing string suspended in a subterranean location in a wellbore. The bypass tool has a tubular body for connection to a tubing string with ports in the body wall to inject fluid into the annulus, surrounding the tubing string. In some applications, nozzles are placed in the ports to create fluid jets which can be utilized, for example, for cleaning a subsea BOP. In other applications, fluids are injected into the annulus to assist circulation. An axially shiftable sleeve is mounted in the body's internal bore and acts as a valve to open and block flow through the ports. Spring-loaded detents in the body engage openings in the sleeve to lock the sleeve against axial movement. The detents extend into the sleeve to be engaged by an actuator ball pumped down the tubing string to the bypass tool. In operation, the bypass tool is run into the wellbore in the closed position with the sleeve closing the ports in the mandrel. When bypass flow is desired, an actuation ball is pumped down the wellbore to the bypass tool. The ball engages a seat in the sleeve to block flow down the tubing string. The ball also engages and depresses the detents, unlocking the sleeve to shift axially down the wellbore to the bypass position where ports in the sleeve align with ports in the mandrel to permit flow through the ports. To return the bypass tool to the closed position, a second ball of the same diameter as the first ball is pumped down the well to abut the first ball and engage and depress the detents to allow the sleeve to shift to a closed position. In this closed position, flow through the tubing string is reopened by shifting the ball-seat assembly to an enlarged area of the mandrel bore where fluid is free to flow around the ball seat. | 08-25-2011 |
