| 20120023280 | Atomic Operations with Page Migration in PCIe - A method and data processing system enables scheduling of atomic operations within a Peripheral Component Interconnect Express (PCIe) architecture during page migration. In at least one embodiment, firmware detects the activation of a page migration operation. The firmware notifies the I/O host bridge, which responds by setting an atomic operation stall (AOS) bit to a pre-established value that indicates that there is an ongoing migration within the memory subsystem of a memory page that is mapped to that I/O host bridge. When the AOS bit is set to the pre-established value, the I/O host bridge prevents/stalls any received atomic operations from completing. The I/O host bridge responds to receipt of receipt of an atomic operation by preventing the atomic operation from being initiated within the memory subsystem, when the AOS bit is set to the pre-established value. The AOS bit is reset when the migration operation has completed. | 01-26-2012 |
| 20120023302 | Concurrent Atomic Operations with Page Migration in PCIe - A method and data processing system enables scheduling of atomic operations within a Peripheral Component Interconnect Express (PCIe) architecture during page migration. In at least one embodiment, firmware detects the activation of a page migration operation and sets a migration bit in the page table. When the PCIe Host Bridge (PHB) receives an atomic operation, the PHB checks the migration bit associated with the memory page targeted by the atomic operation and if the migration bit is set, the PHB buffers the atomic operation and sets an atomic operation stall (AOS) bit associated with the buffer. The atomic operation is stalled until the migration bit is reset, at which time the PHB resets the AOS bit of the buffer. The atomic operations are permitted to continue when the migration bit of the target memory page is not set, and along with DMA operations, may bypass other stalled atomic operations. | 01-26-2012 |

| 20120036401 | SELECTION OF A DOMAIN OF A CONFIGURATION ACCESS - A data processing system includes an input/output (I/O) host bridge to which at least one I/O adapter is coupled by an I/O link. In a register of the I/O host bridge, a configuration partitionable endpoint (PE) field is set to identify a PE to be used for an I/O configuration operation. Thereafter, the host bridge initiates the I/O configuration operation on the I/O link and determines if an error occurred for the I/O configuration operation. In response to a determination that an error occurred for the I/O configuration operation, an error state is set in the I/O host bridge only for the PE indicated in the configuration PE field of the register in the I/O host bridge, wherein I/O configuration errors are isolated to particular PEs. | 02-09-2012 |

| 20120008136 | GEODESIC MEASUREMENT SYSTEM AND METHOD FOR IDENTIFYING A TARGET UNIT HAVING A GEODESIC MEASUREMENT DEVICE - A geodesic measurement system having a geodesic measurement device. A unique identification code is allocated to each of the target objects, such that the target objects can be differentiated from one another based on the identification code. The measurement device has a distance and angle measurement functionality for determining the position of the target objects. The measurement device is designed for emission of the beam such that the identification code of a target object that is searched for from the target object volume can be modulated to the beam as a code to be searched for. The target unit has an evaluation component connected to the detector for inspecting correspondence between the code modulated to the beam and the own identification code of the target unit and a transmission component for transmission of a reactive confirmation signal to the geodesic measurement device that takes place upon correspondence being determined. | 01-12-2012 |
| 20120011733 | LEVELING DEVICE AND LEVELING METHOD - A leveling device having a sighting device that defines an alignment axis, an imaging system, spatially separated from the sighting device, having an imaging lens to which a lens primary plane is allocated and a detector having a recording surface lying in an image plane and an evaluation device that is connected to the detector. A visual field of the imaging system is defined by the imaging lens and the detector as the maximum angle range within which points can be registered by the imaging lens by means of the recording surface of the detector. The imaging lens and the detector are designed and arranged relative to one another and to a lens plane comprising the alignment axis such that all points of the lens plane within the visual field are simultaneously imaged in focus on the recording surface of the detector. | 01-19-2012 |

| 20110258923 | THERMOFORMED GROW TUBE - A grow tube formed from a sheet of thermoform polymer to include a plurality of longitudinal ribs that protrude in a first direction normal to the plane of the sheet. When rolled into a grow tube, the ribs can extend radially inward and act as cushions that prevent the stem of the resident plant from colliding with or resting on the continuous rim of the grow tube. The ribs can also define vertically oriented channels that are open to the interior of the grow tube. Natural convection currents develop in the channels, promoting air exchange between the interior of the grow tube and the surroundings. The ribs can promote diffusion of the incoming sunlight. In one embodiment, the grow tube includes snap forms that overlap when the sheet is rolled into tubular form to provide a flangeless grow tube. | 10-27-2011 |

| 20110283809 | MULTIPHASE FLOWMETER WITH BATCH SEPARATION - A process fluid flow system is provided having an input, an output, and a plurality of fluid circuits disposed between the input and output. At least one valve is disposed to selectably cause process fluid to flow through either a first circuit of the plurality of circuits, or a second circuit of the plurality of circuits. Process fluid flows through the first circuit during normal production, and through the second circuit during process fluid sequestration. A process fluid flow measurement device is operably interposed between the input and output and configured to measure total flow through the system. A separator is disposed in the second circuit and is arranged to allow the process fluid to separate gravitationally over time into immiscible components of the process fluid, the separator having a known internal volume. A guided wave radar level measurement device is preferably disposed to measure heights of interfaces within the separator. A controller is coupled to at least one valve, the process fluid flow measurement system, and the guided wave radar level measurement device. The controller is configured to combine total process fluid flow information from the process fluid flow measurement device with measured height information from the guided wave level measurement device to provide fractional flow rates for at least one immiscible component of the process fluid. | 11-24-2011 |
