20130125552 | GAS TURBINE ENGINE LOCKOUT REDUCTION - A method is provided of reducing lockout time of a gas turbine engine which includes: an inlet, a compressor, a combustor, a turbine, and an exhaust duct, where the compressor and the turbine are carried on a turbomachinery rotor and each include an array of blades mounted for rotation inside a casing of the engine. The method includes: operating the engine at a first power output; shutting down operation of the engine without substantially reducing the power output beforehand, wherein thermomechanical changes occur in the engine subsequent to shutdown that tend to reduce a radial clearance between at least one of the blades and the casing; and subsequent to shutting down the engine, (1) heating the casing and/or (2) pumping an airflow of ambient air into the inlet and through the casing, past the rotor, and out the exhaust duct, so as to reverse at least partially the thermomechanical changes. | 05-23-2013 |

20140145884 | PACKAGE STRUCTURES TO IMPROVE ON-CHIP ANTENNA PERFORMANCE - A radio frequency integrated circuit (RFIC) chip package is provided having an RFIC chip and an integrated antenna structure. The integrated antenna structure includes an on-chip antenna having one or more radiator elements formed as part of a back-end-of-line structure of the RFIC chip. The antenna structure further includes a superstrate structure disposed on the back-end-of-line structure of the RFIC chip. The superstrate structure includes at least one substrate layer and a focusing metal element. The focusing metal element has a structure that is complementary to the on-chip radiator elements and which is configured to focus electromagnetic radiation to and from the planar antenna structure. The superstrate structure improves the performance (e.g., antenna gain and bandwidth) of the on-chip antennas for millimeter-wave applications. | 05-29-2014 |
