Abstract: A compressor blade having an airfoil that comprises oppositely-disposed convex and concave surfaces, oppositely-disposed leading and trailing edges defining therebetween a chord length of the airfoil, a forward-most nose of the airfoil located at the leading edge and having a profile, a blade tip, and an erosion-resistant coating. The coating is present on the concave surface near the trailing edge, optionally present on the nose, optionally present on the convex surface, wherein the convex surface is free of the erosion resistant coating within at least 20% of the chord length from the nose. The thickness of the coating on the concave surface, the convex surface, and the nose is such that, if the gas turbine engine is exposed to an erosive environment, deterioration of the concave surface, the convex surface and the leading edge does not form a pronounced cusp at an intersection of the convex surface and leading edge.

Abstract: Improved imaging systems are disclosed. More particularly, the present disclosure provides for an improved image sensor assembly for an imaging system, the image sensor assembly having an integrated photodetector array and its associated data acquisition electronics fabricated on the same substrate. By integrating the electronics on the same substrate as the photodetector array, this thereby reduces fabrications costs, and reduces interconnect complexity. Since both the photodiode contacts and the associated electronics are on the same substrate/plane, this thereby substantially eliminates certain expensive/time-consuming processing techniques. Moreover, the co-location of the electronics next to or proximal to the photodetector array provides for a much finer resolution detector assembly since the interconnect bottleneck between the electronics and the photodetector array is substantially eliminated/reduced.

A designated signal and one or more characteristics corresponding to a plurality of imaging gradient waveforms are received. Further, a tracking pulse sequence is synchronized with an imaging pulse sequence at a determined point based on the designated signal. The tracking pulse sequence is then applied simultaneously with the imaging pulse sequence for acquiring corresponding response signals from an interventional device that includes at least one tracking coil and a tracking source configured to generate response signals at a tracking resonant frequency different from an imaging resonant frequency. A location of the tracking coil within or outside body of a subject is determined based on the response signals received from the tracking source and the characteristics corresponding to the imaging gradient waveforms.

Patent number: 8850878
Abstract: Various methods and systems are provided for a turbocharger. In one example, a method includes receiving a signal indicative of a monitored pressure of a pressurized oil supply of a turbocharger or other turbomachine. The method further includes determining whether a high frequency component of the signal meets one or more designated criteria, and, if the high frequency component of the pressure meets the one or more designated criteria, generating a first control signal.

Patent number: 8851846
Abstract: A platform cooling arrangement in a turbine rotor blade having a platform that includes an interior cooling passage formed therein. The platform cooling arrangement may include: a main plenum residing just inboard of the planar topside and extending from an aft position to a forward position within one of the pressure side and the suction side of the platform, the main plenum having a longitudinal axis that is approximately parallel to the planar topside; a supply plenum that extends between the main plenum and the interior cooling passage; and a plurality of cooling apertures, each cooling aperture extending from one of the pressure side and the suction side slashface to a connection with the main plenum.

Patent number: 8850818
Abstract: Systems and methods for supplying fuel to a gas turbine are described. A fuel may be received, and one or more parameters associated with the received fuel may be determined. Based at least in part upon the determined one or more parameters, a desired pressure for removing one or more liquids from the fuel utilizing a separator may be calculated. The operation of a pressure changing device may then be controlled in order to achieve the desired pressure. In certain embodiments, the operations of the method may be performed by a controller that includes one or more computers.

Patent number: 8850894
Abstract: A device and a method for ultrasonic testing by means of a local immersion technique of a stringer component section of a flat component are provided. The device includes a test head assembly mounted as moving floatingly by a holding device in the Y-direction longitudinally. The test head assembly includes: a test head that can be connected to an automatically actuated handling device and that can be moved by the handling device along the stringer; a test head holder; and a counter-holder coupled with the test head holder by an actuation element, wherein the actuation element is configured to steer the test head holder and the counter-holder from a closed position to an open position, the test head holder and the counter-holder being mounted floatingly along a guiding rail running in the X-direction transversely to the stringer, and fit, in a force-loaded manner, to each side surface of the stringer.

Patent number: 8850811
Abstract: Systems and methods for determining compression device degradation of an engine of a rail vehicle are provided. In one embodiment, a rail vehicle system includes an engine, an air-intake passage coupled to the engine, a compression device including a compressor positioned along the air-intake passage, a barometric air pressure sensor for measuring a barometric air pressure upstream of the compressor, a manifold air pressure sensor for measuring a manifold air pressure downstream of the compressor, and a controller configured to adjust a rail vehicle operating parameter responsive to a determination of compression device degradation based on a negative pressure differential between the manifold air pressure and the barometric air pressure during a designated operating condition.

Patent number: 8853594
Abstract: Methods and apparatus for welding a component to fill a groove therein. The method entails simultaneously projecting an electric arc and at least first and second laser beams into the groove. The electric arc melts and deposits a filler material in the groove while the first and second laser beams are projected onto opposite first and second walls, respectively, of the groove. The axis of each of the first and second laser beams is oriented at an acute angle relative to the respective wall thereof.
