20080225255 | CONFORMING SEATS FOR CLAMPS USED IN MOUNTING AN OPTICAL ELEMENT, AND OPTICAL SYSTEMS COMPRISING SAME - Clamps are disclosed for holding an optical element relative to a support. An exemplary clamp includes first and second arms and a member connecting the arms such that a portion of a mounting feature of the optical element is between the first and second arms. The first arm applies a clamping force toward a respective portion of the mounting feature, and the second arm includes a seat. The seat has at least upper and intermediate portions. The upper portion engages the respective location on the mounting feature. The intermediate portion is situated between the upper portion and the second arm and has a lateral thickness less than the lateral thickness of the upper portion. The intermediate portion exhibits elastic and plastic deformability sufficient for any moment applied by the clamp to the mounting feature to be limited to less than a designated peak moment, while maintaining substantially full engagement of the upper portion with the respective location. | 09-18-2008 |
20090033907 | DEVICES AND METHODS FOR DECREASING RESIDUAL CHUCKING FORCES - Devices and methods are disclosed for holding a reticle or analogous object, particularly a planar object. An exemplary reticle-holding device includes a reticle chuck having a reticle-holding surface on which a reticle is placed to hold the reticle. The device includes at least one ultrasonic transducer (as an exemplary vibration-inducing device) sonically coupled to the reticle to excite, whenever the ultrasonic transducer is being energized, a vibrational mode in the reticle or reticle chuck, or both. The vibration mode is sufficient to reduce an adhesion force holding the reticle to the reticle-holding surface. Sonic coupling can be by direct contact with the transducer or across a gap. | 02-05-2009 |
20110242511 | Apparatus and methods for inhibiting immersion liquid from flowing below a sustrate - A substrate stage is provided with an immersion liquid collection member that surrounds at least an alignment feature of the substrate stage used to align the substrate on the stage by engaging alignment structure of the substrate. The collection member is located at least partly below the periphery of the substrate held by the substrate holding member of the substrate stage. The collection member has an uppermost liquid-receiving surface that preferably is spaced below a lowermost surface of the substrate when the substrate is held by the substrate holding member. The collection member collects liquid that flows along the alignment feature so as to prevent that immersion liquid from flowing along the under-surface of the substrate. | 10-06-2011 |
20120320362 | MULTIPLE-BLADE HOLDING DEVICES - An exemplary device includes first and second portions that are movably connected together by first and second sets, respectively, of multiple blades interleaved with each other at an overlap region. When the overlap region is compressed, displacement of the first and second portions relative to each other is prevented so as to provide relatively high stiffness in first and second orthogonal directions (e.g., z- and y-directions) and relatively low stiffness in a third orthogonal direction (e.g., x-direction). The device can be used in coordination with an actuator, wherein operation of the actuator and compression of the overlap region are automated. | 12-20-2012 |

20090121539 | BRAKE PIPE VENT VALVE FOR LOCOMOTIVE BRAKE SYSTEM - The present locomotive brake system includes a brake controller operable by an operator and a brake pipe vent valve. The brake controller includes an emergency output port which provides emergency pneumatic signal on the emergency output port when the brake controller is in an emergency position. The brake pipe vent valve includes a housing having brake pipe, emergency input and exhaust ports, and first and second valves. The emergency output port is fluidly connected to the emergency input port. The first valve selectively connects the brake pipe port to the exhaust port when opened in response to an emergency signal on the brake pipe port. The second valve selectively connects the brake pipe port to the exhaust port when opened in response to an emergency signal on the emergency input port. | 05-14-2009 |

20090192740 | MARK EXTENSION FOR ANALYSIS OF LONG RECORD LENGTH DATA - A method of analysis of long record length data using mark duration includes displaying together with a portion of the long record length data each mark that identifies a specified feature of interest together with the mark duration. Associated with the mark may be text identifying the feature of interest, measurement values associated with the duration of the mark, or a combination thereof. Multiple sets of marks may be generated for the long record length data, which sets may be combined to generate new marks with duration. The marks also may be filtered to further refine the marks to be displayed according to user specified criteria. In this way analysis of long record length data representing an acquired signal may be readily automated so a user may move from one interesting event to another without having to pan through the long record length data. | 07-30-2009 |
