Patent number: 8852234Abstract: An apparatus for anchoring a rod to a bone fastener in a spine stabilization system. A first resilient insert may have two deflectable arms and a first channel formed therein. A second resilient insert may have two deflectable arms and a second channel formed therein. A cylindrical body may have a passage, wherein the first resilient insert and the second resilient insert have a width greater than the inner diameter of the cylindrical body when the first resilient insert is in a neutral state. Advancement of the first resilient insert or the second resilient insert into the passage deflects the two deflectable arms inward, causing the width of the first or second channel to decrease, and inhibiting the first resilient insert or the second resilient insert from moving relative to the cylindrical body.Type: GrantFiled: June 1, 2012Date of Patent: October 7, 2014Assignee: Zimmer Spine, Inc.Inventors: Wesley Hunt, H.

Publication number: 20080182208Abstract: Aspects of the present disclosure provide a method and a system for closing plate take-over in immersion lithography. A plate holder is provided for a closing plate in a wafer holder of an immersion lithography system. An optical detector is provided below the plate holder for determining whether a light signal passing through the closing plate is aligned with the plate holder using the optical detector. If the light signal is aligned, a fluid containment mechanism is lowered, and the closing plate is placed into the plate holder. Alternatively, the fluid containment mechanism is lowered to surface of the closing plate, the closing plate is affixed to the mechanism, and the mechanism is raised with the closing plate. If the light signal is not aligned, an error is triggered and the scanner is stopped.Type: ApplicationFiled: January 25, 2007Publication date: July 31, 2008Applicant: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Tzung-Chi Fu, Hsin (Alex) Chang
