Abstract: A power converter includes first and second DC terminals between which the power converter is operable to generate a voltage difference. The power converter also includes a control unit that is configured to operate in a normal mode during normal operation of the power converter and in a fault mode when a fault occurs in a respective DC power transmission medium that is operatively connected in use to one of the first or second DC terminals. The control unit in the normal mode generates a normal operating voltage difference between the first and second DC terminals. The control unit in the fault mode generates a modified operating voltage difference between the first and second DC terminals while maintaining the respective voltage potential with respect to earth of the other of the first and second DC terminals. The modified operating voltage difference is lower than the normal operating voltage difference.

Abstract: Systems and methods for obtaining and displaying a collimated X-ray image are described. The methods can include providing an X-ray device having an X-ray source, a square or rectangular X-ray detector, and a collimator. The collimator can be sized and shaped to collimate an X-ray beam from the X-ray source that exposes a receptor region on the detector. The collimator can allow the X-ray image received by the X-ray detector to have any suitable shape that allows a relatively large view of the image to be displayed and rotated on the display device without changing the shape or size of the image as it rotated. In some instances, the collimator provides the image with superellipse shapes or cornerless shapes having four substantially straight edges with a 90 degree corner missing between at least two edges that run substantially perpendicular to each other. Other embodiments are described.

Abstract: A robot with improved cleanliness for use in a clean environment is disclosed, having a uniform flow through the open interface between the clean environment and the interior of the robot housing, passing the particle generation area to an exhaust port, keeping the particles from the clean environment. The uniform flow reduces or eliminates the back flow, and further allows the scalability of the open interface to prevent particles generated from moving mechanisms within the robot housing to contaminate the clean environment. The uniform flow can be established by designing the flow dynamic, centering the exhaust port, or by restricting the flow along the elongated slot, for example, by uniformly restricting the flow along the elongated slot, or by implementing a restrictor along the elongated slot.

Abstract: Systems and methods for making and using a multi-blade collimator device are described herein. The collimator device can include a base member, a rotational member, and multiple X-ray-attenuating blades that fit together to define an aperture. The blades are typically disposed between the base member and rotational member. Additionally, the blades can be mechanically connected to or interfaced with the base member and the rotational member so that when the rotational member is rotated with respect to the base member, the blades move and cause the aperture to change in size. The aperture can be any shape, including polygonal, square, or rectangular. While the aperture's size can be increased and decreased, the shape and orientation of the aperture can remain substantially constant. The collimator can contain a single layer of blades or multiple layers of blades. Other embodiments are described.
