The logging tool control module is also operable to determine one or more expected sensor signals, determine error values using the expected sensor signals and the sensor signals received from the one or more sensors, and compare the error values with one or more thresholds.
WO/2016/022120 MULTI-ZONE ACTUATION SYSTEM USING WELLBORE PROJECTILES AND FLAPPER VALVES||WO||11.02.2016|
||PCT/US2014/050071||HALLIBURTON ENERGY SERVICES, INC. ||WALTON, Zachary William |
An example sliding sleeve assembly includes a body that defines an inner flow passageway and one or more ports. One or more sensors are positioned on the body to detect wellbore projectiles that traverse the inner flow passageway, and a sliding sleeve is arranged within the body and movable between a closed position, where the sliding sleeve occludes the one or more ports, and an open position, where one or more ports are exposed. A flapper valve is arranged within the body and movable between an open configuration, where the flapper valve allows fluid flow through the inner flow passageway, and a closed configuration, where the flapper valve seats against a flapper seat defined on the sliding sleeve and prevents fluid flow through the inner flow passageway. An actuation sleeve is arranged within the body and movable to allow the flapper valve to move to the closed configuration.
WO/2016/022135 FUEL INJECTION SYSTEM FOR A TURBINE ENGINE||WO||11.02.2016|
||PCT/US2014/050253||SIEMENS AKTIENGESELLSCHAFT ||BERTONCELLO, James |
A fuel system (10) for a gas turbine engine that improves efficiency by supplying fuel to a primary stage (14) and secondary stage (16) via a common fuel source (18) is disclosed. The fuel system (10) may be formed from first and second primary injector assembly stages (20, 22) and a first premix injector assembly stage (24) positioned upstream from a combustor chamber (26), whereby the first premix injector assembly stage (24) is a secondary injector system. The second primary stage (22) and the first premix stage (24) may be in fluid communication with the same fuel source (18) to eliminate duplicative components found within systems where fuel is supplied individually to the second primary stage and the first premix stage. In at least one embodiment, the second primary injector assembly stage (22) and the first premix injector assembly stage (24) may each be in communication with a fuel manifold (28) configured to supply more fuel to the second primary stage (22) than the first premix stage (24).
WO/2016/022136 INTERSTAGE SEAL HOUSING OPTIMIZATION SYSTEM IN A GAS TURBINE ENGINE||WO||11.02.2016|
||PCT/US2014/050255||SIEMENS ENERGY, INC. ||ZHANG, Jiping |
An interstage seal system (10) for adjusting the position of an interstage seal during operation of a gas turbine engine (14) to increase efficiency of the seal (12) is disclosed. The interstage seal system (10) may include a interstage seal housing (16) formed from a circumferentially extending housing having a seal (12) positioned on a radially inward surface (18) of the interstage seal housing (16). The interstage seal housing (16) may biased radially outward via one or more springs (20) to bias the radially inward surface (18) of the interstage seal housing (16) outwardly. The interstage seal housing (16) may reside in an interstage housing receiving cavity (68). The cavity (68) may be supplied with gases at a higher pressure than on the other side (24) of the seal housing (16) during turbine engine operation. As such, the interstage seal housing (16) is forced radially inwardly to close the gap (26) within the seal (12) as the high pressure force directed radially inward overcomes the spring bias directed radially outward.

||PCT/US2014/050310||HALLIBURTON ENERGY SERVICES, INC. ||MAXEY, Jason Eric |
A flow conditioning opening may be used to manipulate the flow of particulates in a particulate laden fluid in a downhole environment. The particulate flow may be manipulated towards or away from openings downstream of the flow conditioning opening. For example, a perforation cluster may include a flow conditioning opening extending from the wellbore into the subterranean formation that is aligned axially along the wellbore with and uphole of a perforation, wherein the flow conditioning opening has at least one of characteristic selected from the group consisting of: a smaller cross-sectional area at the wellbore than the perforation, a smaller volume than the perforation, a smaller depth into the subterranean formation than the perforation, and any combination thereof.
WO/2016/022155 SENSOR-BASED SAFETY FEATURES FOR ROBOTIC EQUIPMENT||WO||11.02.2016|
||PCT/US2014/050405||ROBOTIC VISION TECHNOLOGIES, LLC ||HUNT, Shawn |
Technologies are generally described for sensor-based safety features for robotic equipment, and the implementation thereof. One or more sensors may be positioned relative to the robotic equipment such that the sensors may capture light from at least a portion of an environment surrounding the robotic equipment. In some examples, the sensors may be integrated with the robotic equipment and/or may be configured to rotate. An analysis module coupled to the sensors may build a model image of the environment based on the light captured by the sensors. The analysis module may detect that an unintended object is approaching the robotic equipment in response to detecting a change in the model image, and based on a proximity and/or a speed of approach of the object to the robotic equipment, the analysis module may instruct the robotic equipment to reduce an operating speed and/or stop motion of the robotic equipment.

One of the plurality of error counters may count errors, detected by the on-die ECC, in a memory unit on the memory device. A post package repair (PPR) may be initiated on the memory device in response to a determination that a value of the one of the plurality of error counters equals a threshold value.
WO/2016/022157 VIRTUALIZATION OF NATURAL RADIO ENVIRONMENTS TO TEST A RADIO DEVICE||WO||11.02.2016|
||PCT/US2014/050418||INTEL CORPORATION ||MONGHAL, Guillaume |
Natural radio environments are virtualized to test radio devices. In one example, this is done by extracting signals and messages recorded in the field and injecting them in the operation of a protocol tester. In another example, the radio environment is reproduced by generating channel impulse responses in a ray-tracer, then interpolating them in a channel emulator and supporting the interpolation by means of post-processing. In another example, the radio environment is recorded using a mobile terminal in the field. In another example, natural radio environments are produced by reconstructing realistic cell loads and, as a consequence, intra-cell interference for a given device under test
