Patent number: 9250188
Abstract: A system and method for measuring cooling effectiveness of a component is disclosed. The method includes providing a component with a coating applied on a surface of the component. Further, the method includes supplying a first gaseous medium over a surface of the component through a plurality of holes in the component and feeding a second gaseous medium along the surface of the component. Further, the method includes exposing the surface of the component to the first and second gaseous mediums for a predetermined period. The method further includes obtaining an image of the surface of the component exposed to the first and second gaseous mediums for the predetermined period. The method includes analyzing the obtained image to determine whether at least a portion of the coating is removed from the surface of the component upon exposure to the second gaseous medium.

Patent number: 9250212
Abstract: A method of selecting one element among a plurality of elements of a phased-array ultrasonic weld inspection arrangement during inspection of a weld to obtain optimum weld inspection coverage. The weld connects portions of material having a known thickness. The elements extend along an ultrasonic transmission wedge of the arrangement that supports the extent of the elements at a wedge angle relative to the welded material. The method includes utilizing material thickness, offset distance of an edge of the wedge from a weld centerline and number of elements within calculation that yields the selection.

Patent number: 9250245
Abstract: Methods comprising the use of photoactivated chemical bleaching for detecting multiple targets in a biological sample are provided. The methods include the steps of providing a biological sample containing multiple targets, binding at least one probe to one or more target present in the sample, and observing a signal from the probe. The method further includes the steps of contacting the sample comprising the bound probe with an electron transfer reagent and irradiating the sample, thereby initiating a photoreaction that substantially inactivates the probe by photoactivated chemical bleaching. The method further includes the steps of binding at least one probe to one or more target present in the sample, and observing a signal from the probe. The process of binding, observing and bleaching may be iteratively repeated.

Patent number: 9251421
Abstract: In accordance with one aspect of the present technique, a method is disclosed. The method includes receiving a new video from one or more sensors and generating a new content graph (CG) based on the new video. The method also includes comparing the new CG with a plurality of prior CGs. The method further includes identifying a first portion of the new CG matching a portion of a first prior CG and a second portion of the new CG matching a portion of the second prior CG. The method further includes analyzing a first set of semantic annotations (SAs) associated with the portion of the first prior CG and a second set of SAs associated with the portion of the second prior CG. The method further includes generating a sequence of SAs for the new video based on the analysis of the first and the second set of SAs.
