20100157103 | HIGH RESOLUTION ZOOM: A NOVEL DIGITAL ZOOM FOR DIGITAL VIDEO CAMERA - A camera system and a method for zooming the camera system is disclosed. The method generally includes the steps of (A) generating an electronic image by sensing an optical image received by the camera, the sensing including electronic cropping to a window size to establish an initial resolution for the electronic image, (B) generating a final image by decimating the electronic image by a decimation factor to a final resolution smaller than the initial resolution and (C) changing a zoom factor for the final image by adjusting both of the decimation factor and the window size. | 06-24-2010 |

20100260323 | X-RAY TUBE HAVING A FERROFLUID SEAL AND METHOD OF ASSEMBLING SAME - An x-ray tube includes a vacuum enclosure, a shaft having a first end and a second end, a flange attached to the first end of the shaft, the flange having an outer perimeter, and a ferrofluid seal assembly having an inner bore, the inner bore having an outer perimeter smaller than the outer perimeter of the flange. The shaft is inserted through the bore of the ferrofluid seal assembly such that the ferrofluid seal assembly is positioned between the first end of the shaft and the second end of the shaft and such that the first end extends into the vacuum enclosure, and the ferrofluid seal is configured to fluidically seal the vacuum enclosure from an environment into which the second end of the shaft extends. | 10-14-2010 |
20100260324 | AIR-COOLED FERROFLUID SEAL IN AN X-RAY TUBE AND METHOD OF FABRICATING SAME - An x-ray tube includes a rotatable shaft having a first end and a second end, a target coupled to the first end of the rotatable shaft, the target positioned to generate x-rays toward a subject upon impingement of electrons thereon, and an impeller coupled to the second end of the rotatable shaft and positioned to blow a gas into an inlet of an aperture passing into the rotatable shaft. | 10-14-2010 |
20110007877 | APPARATUS AND METHOD OF COOLING A LIQUID METAL BEARING IN AN X-RAY TUBE - An x-ray tube includes a center shaft having an inner surface and an outer surface, the inner surface forming a portion of a cavity therein, a mount having an inner surface, the mount having an x-ray target attached thereto, and a liquid metal positioned between the outer surface of the center shaft and the inner surface of the mount. The x-ray tube further includes a flow diverter positioned in the cavity, the flow diverter having a wall with an inner surface, and a plurality of jets passing through the wall, wherein the plurality of jets are configured such that when a fluid is flowed into the flow diverter and passes along its inner surface, a portion of the fluid passes through the plurality of jets and is directed toward the inner surface of the center shaft. | 01-13-2011 |
