20130335733 | System With Multiple Scattered Light Collectors - A method for inspecting a surface of a workpiece for asymmetric defects, by scanning an incident beam on the surface of the workpiece to impinge thereon to create reflected light extending along a light channel axis in a front quartersphere and scattered light, the incident beam and the light channel axis defining an incident plane, collecting the scattered light at a plurality of collectors disposed above the surface at defined locations such that scatter from asymmetric defects is collectable by at least one collector, detecting collector output and generating signals in response, and processing the signals associated with each collector individually to obtain information about asymmetric defects. | 12-19-2013 |
20150042987 | Front Quartersphere Scattered Light Analysis - A surface inspection system, as well as related components and methods, are provided. The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The optical collection and detection system features, in the front quartersphere, a light channel assembly for collecting light reflected from the surface of the workpiece, and a front collector and wing collectors for collecting light scattered from the surface, to greatly improve the measurement capabilities of the system. The light channel assembly has a switchable edge exclusion mask and a reflected light detection system for improved detection of the reflected light. | 02-12-2015 |

20080304057 | SYSTEM AND METHOD FOR CONTROLLING LIGHT SCATTERED FROM A WORKPIECE SURFACE IN A SURFACE INSPECTION SYSTEM - In one embodiment, a surface analyzer system comprises a radiation targeting assembly to target a radiation beam onto a surface; and a scattered radiation collecting assembly that collects radiation scattered from the surface. The radiation targeting assembly generates primary and secondary beams. Data collected from the reflections of the primary and secondary beams may be used in a dynamic range extension routine, alone or in combination with a power attenuation routine. | 12-11-2008 |

20100278956 | METHOD FOR RETAINING A VASCULAR STENT ON A CATHETER - A method of securely mounting a stent on a balloon of a balloon catheter. The method generally includes crimping a stent on a balloon of a balloon catheter, and positioning the balloon with the drug delivery stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold as the mold radially restrains the stent from expanding. The stent is recrimped on the balloon after removal from the mold to increase retention of the stent on the balloon. | 11-04-2010 |
20110203739 | METHOD FOR RETAINING A VASCULAR STENT ON A CATHETER - A method of securely mounting a stent on a balloon of a catheter. The method generally includes crimping a stent on a balloon of a catheter at least one time, and positioning the balloon with the stent thereon within a polished bore of a mold formed at least in part of a metallic material. The balloon is pressurized and heated within the mold, or within a sheath, in two stages as the stent is restrained from radially expanding. The method may include crimping the stent onto the balloon one or two times during processing. The method increases retention of the stent on the balloon catheter following sterilization. | 08-25-2011 |
