摘要： A method for analysis includes directing a converging beam of X-rays toward a surface of a sample having multiple single-crystal layers, including at least a first layer and a second layer that is formed over and tilted relative to the first layer. The X-rays that are diffracted from each of the first and second layers are sensed simultaneously while resolving the sensed X-rays as a function of angle so as to generate a diffraction spectrum including at least a first diffraction peak due to the first layer and a second diffraction peak due to the second layer. The diffraction spectrum is analyzed so as to identify a characteristic of at least the second layer.

摘要： Apparatus for inspection of a disk, which includes a crystalline material and has first and second sides. The apparatus includes an X-ray source, which is configured to direct a beam of X-rays to impinge on an area of the first side of the disk. An X-ray detector is positioned to receive and form input images of the X-rays that are diffracted from the area of the first side of the disk in a reflective mode. A motion assembly is configured to rotate the disk relative to the X-ray source and detector so that the area scans over a circumferential path in proximity to an edge of the disk. A processor is configured to process the input images formed by the X-ray detector along the circumferential path so as to generate a composite output image indicative of defects along the edge of the disk.

The control system comprises a voltage sensing system to sense a voltage on a collector terminal of the switching device and provide a voltage sense signal; a controller; and a drive modulation system coupled to an output of the controller for modulating a drive to the control terminal of said bipolar switching device responsive to a controller control signal; wherein said controller is configured to monitor changes in the sensed voltage during a period when said switching device is switched on and to control said drive modulation system to control the degree of saturation of said bipolar switching device when the device is switched on and hence improve turn-off times.

摘要： A globally-addressable array of electronic circuit elements having distributed intelligence. Each circuit element location is connected to a common bus structure which can address each circuit element and transfer data to and from each element. Logic circuitry at each circuit element location recognizes data addressed to a respective circuit element location, and converts data received into an operating level for a respective transducer element. Data transfer to each element location can be made using conventional compression techniques. The data transfer can be bidirectional so that a sensed condition may be transferred from the location over the common bus structure.
