20140057681 | Adaptive Noise Mitigation for Touch-Screen Displays - Touch-screen controllers, particularly those in mobile telephones, are prone to erratic behavior when the mobile telephone is plugged into devices, such as AC power adapters, that create electrical noise. To more intelligently mitigate noise in these and other electronic devices that include capacitive touch-screen displays, the present inventors devised, among other things, a touch-screen controller that measures noise level in the touch-screen display and increases its drive voltage only when necessary to exceed the measured noise level, thereby reducing the chance of noise signals being misinterpreted as touch events while also reducing power consumption over prior techniques. Moreover, for electronic devices that include radio receivers, intelligently increasing the touch-screen voltages based on measured noise, avoids the sensitivity-reduction (desense) issues that providing constant higher operating voltage creates. | 02-27-2014 |

20100236257 | GAS TURBINE COMBUSTOR EXIT DUCT AND HP VANE INTERFACE - An assembly for a gas turbine engine includes a combustor and a vane assembly disposed downstream thereof. A portion of an outer platform of the vane assembly defines an axial sliding joint connection with the combustor, and includes a plurality of depressions located in an outer circumferential surface thereof opposite the combustor. The depressions are disposed in regions of expected higher thermal growth about the circumference of the outer platform such that thermal growth of the entire outer platform is substantially uniform circumferentially therearound. | 09-23-2010 |
20110078902 | METHOD FOR CENTERING ENGINE STRUCTURES - A method for centering an engine structure such as a bearing housing is provided which may be used, for example, during assembly of a mid turbine frame or other engine case structure. In one aspect, the method includes using spacers with respective radial spokes which connect inner and outer portions of the case. In another aspect, centring may be provided by machining selected contacting surfaces of selected components. | 04-07-2011 |
20110081228 | INTERTURBINE VANE WITH MULTIPLE AIR CHAMBERS - A gas turbine engine has a mid turbine frame disposed between turbine rotor assemblies. The mid turbine frame includes hollow airfoils radially extending through an annular gas path duct. The airfoils each include a double-walled leading edge structure to define a front chamber separated from a rear chamber defined in the remaining space within the airfoil. | 04-07-2011 |

20140230404 | GAS TURBINE ENGINE EXHAUST MIXER - An exhaust mixer for a gas turbine engine includes an annular wall having upstream end adapted to be fastened to an engine case and a downstream end forming a plurality of inner and outer mixer lobes. A support member interconnects at least a number of the inner lobes, and includes a circumferentially extending stiffener ring located radially inwardly from the inner lobes and a series of circumferentially spaced apart mixer struts radially extending from the inner lobes to the stiffener ring. The mixer struts have a radial length at least equal to a width of a main gas path defined between the inner lobes and the exhaust cone such that the mixer struts extend entirely through the main gas path. The stiffener ring being fixed solely to the mixer struts such as to float with respect to the exhaust cone and permit relative movement therebetween. | 08-21-2014 |
20140241899 | BLADE LEADING EDGE TIP RIB - A rotor blade for a gas turbine engine includes a leading edge tip rib projecting outwardly from an airfoil of the blade at a tip region thereof. The tip rib continuously surrounds a leading edge of the airfoil and extends rearwardly from the leading edge along respective pressure and suction side surfaces to thereby alter the blade tip leakage vortex structure and strength, resulting in a stage efficiency benefit. | 08-28-2014 |
