20090091745 | Method and system to measure the concentration of constituent elements in an inhomogeneous material using LIBS - A system and method to improve the accuracy of the measure of constituent element(s) in a sample containing domains potentially including the constituent element(s) are described herein. For each domain, the volume of the domain is estimated and the concentration of the constituent element(s) in the domain is determined using LIBS. When all the domains have been analyzed, the volumetric concentration of the domains is summed and divided by the total volume of the sample. Accordingly, by limiting the concentration analysis to separate domains, it is possible to improve the accuracy of the concentration analysis. | 04-09-2009 |

20140109675 | ULTRASONIC TESTING INSTRUMENT WITH DITHERY PULSING - Disclosed is an ultrasonic device optimized with both averaging and dithery pulsing techniques. The averaging technique significantly removes white noise; on the other hand, the dithery pulsing significantly removes acoustic noise, which is otherwise accumulated during conventional averaging processes. | 04-24-2014 |

20130345073 | USE OF ALPHA-2-MACROGLOBULIN FOR DETERMINING OSTEONECROSIS DISEASE STATUS AND FOR SCREENING THERAPEUTIC AGENTS FOR PREVENTING OR TREATING OSTEONECROSIS - The present application presents a method of assessing a predisposition to osteonecrosis in an individual based on the level of expression/activity of alpha-2-macroglubulin, a biomarker whose expression is positively correlated with osteonecrosis. Also provided herein are a diagnostic/prognostic system as well as a software product based on the determination of the level of expression/activity of alpha-2-macroglobulin. Screening methods for the determination of usefulness of an agent in the prevention and/or treatment of osteonecrosis are also provided. | 12-26-2013 |

20130020291 | LASER DRILLING METHODS OF SHALLOW-ANGLED HOLES - A method for providing a shallow-angled hole through a metal component, such as a turbine combustor, includes a step of applying a pulse laser beam to drill a section of the hole substantially within a thermal barrier coating of the component in a trepanning concept. A further step is conducted to apply the pulse laser beam through the completed section of the hole to further drill through a base metal of the component to complete the formation of the hole extending through the component. | 01-24-2013 |
20130020292 | LASER DRILLING METHODS OF SHALLOW-ANGLED HOLES - A method for providing a shallow-angled hole through a thermal barrier coated component in accordance with one aspect thereof, includes a step of applying a pulse laser beam to pre-drill the hole through a base metal of the component. A thermal barrier coating is then applied to the base metal, covering the pre-drilled hole in the base metal. A further step is conducted to apply the pulse laser beam through the thermal barrier coating a location to coincide with pre-drilled hole in the base metal in order to complete the formation of the hole extending through the component. | 01-24-2013 |
20130020293 | LASER DRILLING METHODS OF SHALLOW-ANGLED HOLES - A method for drilling a shallow-angled hole through a thermal barrier coated component includes a step of applying a pulse laser beam to drill a section of the hole substantially within a thermal barrier coating of the component in a direction substantially perpendicular to a top surface of the component. A further step is conducted to apply the pulse laser beam to further drill through a base metal of the component to complete the formation of the hole extending through the component. | 01-24-2013 |
20130020294 | LASER DRILLING METHODS OF SHALLOW-ANGLED HOLES - A method for drilling a shallow-angled hole through a thermal barrier coated component, in accordance with one aspect thereof, includes a step of applying a pulse laser beam with a first setting to drill a section of the hole substantially within a thermal barrier coating of the component. A further step is conducted to apply the pulse laser beam with a second setting through the initiated hole to further drill through a remainder of the component to complete the formation of the hole extending through the component. | 01-24-2013 |
