| 20080258792 | Digital Single Event Transient Hardened Register Using Adaptive Hold - By adjusting a register's capturing clock edge timing so that the register captures data when the data returns to a correct state, the register may be protected against DSET upsets. If a data glitch occurs near the clock edge, the valid time at the register output is increased (CLK to Q). This valid time increase occurs when the presence of a DSET transient is detected near the clock edge. | 10-23-2008 |
| 20090108912 | Circuit Architecture for Radiation Resilience - A system and method for extending the operating life of a device susceptible to defects caused by total ionizing dose radiation and/or bias dependent degradation are described. The device is replicated at least once and at least one switching mechanism is used to cycle between the devices such that only one device is operating normally. While the first device is operating normally, the other devices are biased. The bias condition may slow, eliminate, or even reverse device shifts that occur due to total ionizing dose radiation or bias effects. | 04-30-2009 |

| 20090217858 | GEOSTATIONARY ANCHORING AND RISER ARRANGEMENT ON A SHIP - A geostationary anchoring and riser arrangement in a vessel comprises a rotating body ( | 09-03-2009 |
| 20090233503 | CONNECTION SYSTEM AND METHOD FOR CONNECTING AND DISCONNECTING A FLOATING UNIT TO AND FROM A BUOY WHICH IS CONNECTED TO A SUBSEA INSTALLATION - The present invention relates to a connection system and a method for connecting and disconnecting a floating unit to and from a buoy which is connected to a subsea installation, where the buoy comprises a first connection device for connecting pipes and/or lines for transfer of fluid, control signals and/or electric power between the buoy and the floating unit. The connection system further comprises a support structure which is laterally movable relative to the floating unit and a swivel stack arrangement movably mounted on the support structure. The swivel stack arrangement comprises a second connection device for connecting to the first connection device in the buoy; shut-off devices for opening and closing at least one of the pipes and/or lines in the first and second connection devices by connecting and disconnecting the buoy; and a turret bearing for rotating the buoy relative to the floating unit. | 09-17-2009 |

| 20090158165 | Web Interface for Providing System-Status On-Demand - An Internet web application interfaces to a machine to give users information about the status of the machine. The information on the status of the machine is constantly changing. This design only dynamically builds a web page when the page is requested for viewing. Once built, the page is retained so that the next time it is requested, if the information it contains has not changed, the page can be served without having to be rebuilt. If the information has changed, the design will not update the page until the page has been requested. In addition, the page is only built in the human language requested. | 06-18-2009 |
