    摘要: An imaging system and method for using the same is disclosed. The imaging system includes an x-ray detection array or plurality of detection arrays, a point x-ray source, and a controller. The point x-ray source moves relative to a detection array, each of the x-ray detectors subtending a solid angle at the point source that depends on the relative position of the point source and the detection array and on the location of the detector in the detection array. The signal generated by each x-ray detector depends on a calibration parameter that is independent of the solid angle subtended by that x-ray detector at the point source. The controller stores a table of calibration values that determines the calibration parameter for each of the x-ray detectors. The controller corrects the signals generated by the x-ray detectors for solid angle and for variations in the calibration parameter.

    摘要: A distributed power generation system enabled for assured reliability comprises a direct current power source, a direct current to alternating current converter (DTAC), electrically coupled to the direct current power source, the DTAC comprising a reliability limiting component (RLC) and a sensor for sensing a measurable parameter of the RLC. A decision engine is communicatively coupled to the sensor, and is operable to determine a lifetime estimate for the RLC based on the measurable parameter. A service provider is communicatively coupled to the decision engine by a communication system to receive a signal communicating the lifetime estimate. The service provider schedules preventative maintenance based on the signal communicating the lifetime estimate.

    摘要: A system for forming an image of an object. The system includes a first scanning x-ray source for generating x-rays that diverge from a source point along a first scan path, the point being variable and determined by an input signal provided by a controller. A plurality of x-ray detectors are positioned with respect to the first scan path and are readout by the controller. A conveyor moves the object relative to the first scanning x-ray source and the plurality of x-ray detectors. The object is divided into a plurality of voxels, and the x-ray detectors are positioned such that x-rays pass through each voxel and arrive at one of the detectors when the source point is located at a plurality of points along the first scan path. The controller preferably generates a three-dimensional representation of the object from the x-ray measurements.

    摘要: An apparatus and method for inspecting parts. The apparatus includes an x-ray source for illuminating a part from a plurality of locations with respect to the part and an imaging detector for forming a plurality of measured x-ray images of the part, one such measured x-ray image corresponding to each of the illumination locations. A controller compares each of the measured x-ray images with a corresponding calibration image. The controller provides a defective part indication if one of the measured x-ray images differs from the corresponding calibration image by more than a threshold value in part of the measured x-ray image. The controller localizes defects on the part by comparing two or more of the measured x-ray images with two or more corresponding calibration images. The calibration images can be constructed from measured images of defect free parts.

    摘要: An x-ray imaging system includes an x-ray source for projecting imaging radiation onto a sampled object that is secured by a support member and a detector support assembly having multiple detecting modules distributed in a sparse configuration for detecting imaging radiation that has passed through the object. The x-ray source and the detector support assembly are on opposite sides of the support member. Relative displacement is provided between the object and the imaging radiation. By providing the relative displacements and illuminating the object with pulses of imaging radiation at selected intervals, a time series of successive sub-images corresponding to overlapping regions of the object is captured by each module. Computational algorithms combine the captured sub-images to form a composite three-dimensional description of the sampled object. There are multiple pulses of x-ray illumination for each region of the object, and each pulse irradiates more than one detecting module.

    摘要: The nanostructure-based electronic device comprises a solid support, an organic template layer, a nanostructure and electrodes. The organic template layer is on the surface of the solid support, and has a surface comprising a pair of spaced, electrically-charged regions arranged in tandem in an electrically-neutral background. The nanostructure is elongate, is electrically-conducting, and extends between the charged regions. The electrodes are located the surface of the template layer and are at least co-extensive with the charged regions.
