High tensile strength, creep and corrosion resistant zirconium alloys containing 7.0-10.0 wt% aluminum, 0-3 wt% in total of one or more elements selected from the group consisting of magnesium, tin, chromium, iron, carbon, silicon, yttrium, niobium, molybdenum and beryllium, the balance zirconium and incidental impurities, are produced by annealing cast alloys at a temperature below about 992.degree. C for a period of time sufficient to produce alloys having a substantially continuous matrix of the ordered intermetallic compound Zr.sub.3 Al. The alloys may initially be hot worked at temperatures above about 1000.degree. C, while in the .beta.Zr-Zr.sub.2 Al two phase region, prior to annealing. Preferred alloys contain 7.5-9.5% aluminum, the balance zirconium and incidental impurities.
摘要:
In a method for making a wire guide, a fluoropolymer coating is removed from a distal section of an FP coated core wire to expose a metallic portion. A polymer coating is applied to a proximal section of the FP coated core wire such that the polymer coating overlays at least a portion of the FP coating, and to the distal section of the FP coated core wire including the exposed metal portion. The polymer coating is removed from the FP coating to form the wire guide having a proximal portion with the FP coating and a distal portion with the polymer coating. A hydrophilic coating may be applied to the distal portion over the polymer coating.

A stereographic camera system and method of operating a stereographic camera system. A camera platform may include a first camera head including first left and right cameras separated by a first interocular distance, the first camera head providing first left and right video streams, and a second camera head aligned with the first camera head, the second camera head including second left and right cameras separated by a second interocular distance, the second camera head providing second left and right video streams. An output selector may select either the first left and right video streams or the second left and right video streams to output as a 3D video output. The first interocular distance may be settable over a first range, and the second interocular distance may be settable over a second range, at least a portion of the second range smaller than the first range.
摘要:
A consolidated 2D/3D camera system and method of operation. A consolidated 2D/3D camera system may include a first camera having a first lens and a second camera having a second lens. A 3D frame extractor may extract a first 3D image frame from an image captured by the first camera and extract a second 3D image frame from an image captured by the second camera to provide a stereo image pair. A 2D frame extractor may extract a 2D image frame, different from the first 3D image frame, from the image captured by the first camera.
摘要:
There is disclosed a method and apparatus for acquiring stereoscopic images. A first camera may be mounted to a first convergence plate, the first convergence plate coupled to a first plate via a first XY slide and a first pivot displaced from the first XY slide. A distance between the first plate and a second plate may be adjusted to set an interocular distance between the first camera and a second camera. The first convergence plate may be rotated about the first pivot to set, at least in part, an angle of convergence between the first camera and the second camera.
摘要:
A system and method for adjusting a supply voltage provided by a power supply to a liquid crystal display includes a liquid crystal display having a glass panel, a power supply electrically connected to the liquid crystal display, the power supply configured to provide a supply voltage to the liquid crystal display, a temperature sensor configured to measure the temperature of the glass panel of the liquid crystal display and output a temperature output indicative of the temperature of the glass panel of the liquid crystal display, and a processor in communication with the power supply and the temperature sensor.
摘要:
A method for determining material density variations and prediction of defects on a multi-layer printed circuit board (PCB), in the X, Y, and Z axis, includes a virtual grid creation system and a set of rules for determining the material density in each grid element in the grid system.
摘要:
New photoresists are provided that can be applied and imaged with reduced undesired outgassing and/or as thick coating layers. Preferred resists of the invention are chemically-amplified positive-acting resists that contain photoactive and resin components.
