Application number: 20140268906
Abstract: Methods and systems for current sharing using interleaved LLC power converters are described herein. The method provides for current sharing between a first LLC power converter interleaved with a second LLC power converter. The method includes determining an expected output voltage for at least one of the first and second LLC power converters and measuring an output voltage of at least one of the first and second LLC power converters. The method also includes increasing a dead-time of at least one of the first and second LLC power converters when the measured output voltage exceeds the expected output voltage. Finally, the method includes interleaving the first and second LLC power converters, wherein an output current of the first LLC power converter is substantially equal to an output current of the second LLC power converter.

Application number: 20140268926
Abstract: A high voltage direct current (HVDC) converter system includes a line commutated converter (LCC) configured to convert a plurality of AC voltages and currents to a regulated DC voltage of one of positive and negative polarity and a DC current transmitted in only one direction. The HVDC converter system also includes a buck converter configured to convert a plurality of AC voltages and currents to a regulated DC voltage of one of positive and negative polarity and a DC current transmitted in one of two directions. The LCC and the buck converter are coupled in parallel to an AC conduit and are coupled in series to a DC conduit. The HVDC converter system further includes a filtering device coupled in parallel to the buck converter through the AC conduit. The filtering device is configured to inject AC current having at least one harmonic frequency into the AC conduit.

Application number: 20140270059
Abstract: Embodiments of the systems and methods of this disclosure utilize different positions, or poses, of a target object to collect images that can result in high-resolution volumetric models of the target object. In one embodiment, the object poses define a lateral position and an axial position (also “angular orientation”) of the target object relative to components of an imaging system, e.g., the source of the x-ray beam. The imaging system captures an image of the target object in the object poses. Further processing of the image data that relates to the images generates a volumetric model of the target object at higher resolution, or with fewer artifacts, as compared to similar volumetric models that arise from conventional scanning of these large parts.

Abstract: Automated assessment of registration quality, focus, and area defects in sequentially acquired images, such as images acquired by a digital microscope, is disclosed. In one embodiment, acquired images are registered and whole-image defects are automatically detected based on a figure of merit generated by the registration process. In related implementations, area defects may be automatically detected by calculating correlations in localized image regions for images acquired in different imaging rounds.

Application number: 20140271268
Abstract: This disclosure proposes designs for a fan shroud that dissipates thermal energy from a motor using a single, externally-powered fan design. Examples of the proposed fan shroud allow the cooling fluid to achieve maximum velocity at a position at which the fan shroud exposes the flow to cooler ambient air that surrounds the fan shroud/motor assembly. In this configuration, the high-velocity cooling fluid draws the cooler ambient air towards the surface of the motor, which, in turn, increases the thermal capacity of the moving cooling fluid to dissipate more thermal energy from the motor.
