| 20090055145 | Systems and Methods Involving Engine Models - Systems and methods involving engine models are provided. A representative method for updating a gas turbine engine reference model includes: determining whether an absolute difference between a dominant time constant of a sensor and an assumed sensor model time constant is outside a tolerance value; and responsive to determining that the absolute difference is outside the tolerance value, updating the assumed sensor model time constant with the dominant time constant of the sensor. | 02-26-2009 |

| 20120120974 | 6 KHZ AND ABOVE GAS DISCHARGE LASER SYSTEM - A system and method of operating a high repetition rate gas discharge laser system. The system includes a gas discharge chamber having a hot chamber output window heated by the operation of the gas discharge laser chamber, an output laser light pulse beam path enclosure downstream of the hot chamber window and comprising an ambient temperature window, a cooling mechanism cooling the beam path enclosure intermediate the output window and the ambient window. The gas discharge chamber can include a longitudinally and axially compliant ground rod, including a first end connected to a first chamber wall, a second end connected to a second chamber wall, the second chamber wall opposite the first chamber wall and a first portion formed into a helical spring, the ground rod providing mechanical support for a preionizer tube. | 05-17-2012 |

| 20110088652 | Ram induction system - The method of separating contaminants from a stream of incoming contaminated air to an engine is disclosed wherein the incoming contaminated air stream is separated into a relatively clean air stream and a relatively dirty air stream with the relatively clean air stream being directed to the inlet of the engine and with the relatively dirty air stream being directed to one or more purge exits and out of the system, thereby causing the purged air stream to carry at least some of the original contaminants from the incoming air stream. | 04-21-2011 |

| 20110055255 | METHOD FOR DOWNLOADING A DATA SET TO AN OUTPUT DEVICE - A method for downloading a data set from a network application to an output device, comprising the steps of initiating the network application; uploading search and discovery parameters to the network application to identify and locate the output device, the parameters being selected from geographical locating information, identifying information, prior access and usage information, and combinations thereof; identifying and locating the output device via an algorithm and a database in the network application; and downloading the data set to the output device. The network application preferably is distinct from the output device. The data set may be, for example, a file, an image, a video recording, an audio recording, other digital format file, or a written document. The output device may be, for example, a printer, document display device, laptop computer, mainframe computer, mobile device, video projector, or any other computerized device. | 03-03-2011 |

| 20080229641 | FABRIC ARTWORK WITH MOUNTING ASSEMBLY FOR NESTING IN FRAME - Framed fabric artwork features an artwork canvas with an artwork body having a first set of tabs and an orthogonal second set of tabs wherein the rectangular artwork body has a back surface configured to be attached to a first composite backing structure. The first set of tabs is folded beneath the first composite backing structure and adhered to it. A second composite backing structure is configured to be attached to a lower side of the first set of tabs and the second set of tabs is folded beneath the second composite backing structure and adhered to it. A third composite backing structure is adhered to the lower side of the second set of tabs and also joined to the artwork body which, in turn, is nested in a unitary frame with a rectangular well with upright walls at an outer periphery. The outer periphery of the frame may have bosses adaptable for jewelry uses. | 09-25-2008 |

| 20100040903 | Anisotropically compliant horns for ultrasonic vibratory solid-state bonding - A horn for vibratory solid-state ultrasonic welding of metals and similarly-behaved materials “self-levels” to produce wide continuous seams or large-area spot-welds between delicate workpieces without damage, even if the workpieces are not perfectly flat and parallel to the nominal toolface angle. The horn toolface flexes under pressure to conform to skew-angled workpieces because it is disposed on a tool head supported by a tool neck cut from the tool body. The tool head, the tool neck, or both are anisotropically compliant. When resonances are properly optimized for typical VSS modes of vibration, atypical but useful localized modes are excited at the compliant toolface edges, actually intensifying the bond energy where one might normally expect unwanted damping. Various design approaches optimize the characteristics of the tool head and tool neck to various materials and bonding configurations. The horns can be configured for use with existing ultrasonic welders. | 02-18-2010 |

| 20100180146 | Dynamic Membership Management in a Distributed System - Transactional database replication techniques are disclosed that do not require altering of the database management system implementation. A replicator module includes a dynamic membership manager, which is configured to manage the persistent membership of a coordination group. The persistent membership can be, for example, a durable set of sites that can replicate changes amongst themselves. Changes from sites not in the persistent membership are discarded. The set of recovered members is a subset of the persistent membership. The persistent membership changes incrementally by either removing or adding members. Failed members may still be part of the persistent membership. The dynamic membership manager module manages the modification of the persistent membership, initialization of replicas, and propagation of membership information. | 07-15-2010 |
