Patent number: 7306075Abstract: A dynamic hinge includes a first member connected to a first ladder portion of a ladder, and a second member connected to a second ladder portion. The first member pivots relative to the second member about a pivot axis that does not intersect both the first and second members. The first member includes first and second parallel segments, and the second member includes a third and fourth parallel segments. A guide plate is attached to either the first or second member, and the guide plate is positioned between the first and second segments and between the third and fourth segments. The guide plate includes two non-linear slots, and an other of the first and second members includes two pins, respectively adapted to slide within the two non-linear slots. The pins extend between either the first and second segments or the third and fourth segments.Type: GrantFiled: April 13, 2005Date of Patent: December 11, 2007Assignee: Werner Co.Inventors: David A.

Patent number: 7165649Abstract: A support frame for a folding ladder, a folding ladder positioning system, and a method for installing a folding ladder, are disclosed and pertain to folding ladders disposable within an opening, such as openings in a ceiling of a house, to provide temporary access between one floor or space and another floor or space. In one aspect, a support frame includes a plurality of separable support frame plates collectively configured to circumscribe the opening and a plurality of connection sites are disposed at opposing ends of each of the plurality of separable support frame plates to facilitate connection of each support frame plate to adjacent support frame plates. The connection sites include, for example, mating locking connectors or a plurality of matching through-holes, which permit insertion of a fastening means therethrough.Type: GrantFiled: August 7, 2003Date of Patent: January 23, 2007Assignee: Werner Co.Inventors: Brett A.

Publication number: 20060266508Abstract: A cold plate assembly, which in one embodiment includes a manifold layer comprising one or more input coolant sub-manifold channels and one or more output coolant sub-manifold channels. A metering plate having a plurality of orifices defined there through is disposed adjacent the manifold layer in spaced relation to a cover plate. A core layer is disposed between the metering plate and cover plate, the core layer comprising corrugated fin material. The input sub-manifold channels and output sub-manifold channels are in fluid communication through fluid paths passing through the orifices in the metering plate and the core layer.Type: ApplicationFiled: May 24, 2005Publication date: November 30, 2006Inventors: Scott Johnson, David Winslow

Patent number: 7072786Abstract: Techniques for efficiently setting up inspection, metrology, and review systems for operating upon semiconductor wafers are described. Specifically, this involves setting up recipes that allows each system to accurately inspect semiconductor wafers. The invention gathers pertinent information from these tools and presents the information to users in a way that greatly reduces the time required to complete a recipe. One system embodiment includes an inspection system and a review station that is communicatively linked such that the review station can read from and write to an entire set of data stored at the inspection system. The set of data includes image files of features detected by the inspection system.Type: GrantFiled: September 28, 2005Date of Patent: July 4, 2006Assignee: KLA-Tencor Technologies, CorporationInventors: David Bruce Coldren, Prashant A. Aji, David Winslow Randall, Sharon Marie McCauley

Publication number: 20060102425Abstract: A ladder includes a first section having at least one step. The ladder includes a second section having a least one step. The ladder includes a platform attached to the first and second sections. The ladder includes a hinge mechanism connected to the first section and second section, about which the first section and second section move between an open state, where the first and second sections are in an angular relationship for use, and a folded state where the first and second sections and the platform are essentially in parallel, as shown in FIGS. 4 and 5. The ladder includes a foldable tray mechanism attached to the hinge mechanism about which the foldable tray mechanism moves between the open state independently of the first and second sections, where the foldable tray is in an angular relationship with the first and second sections for use, and a folded state where the foldable tray essentially forms a plane with the first section. A hinge for a stepladder. A step to a ladder.Type: ApplicationFiled: November 17, 2004Publication date: May 18, 2006Inventors: Jason Moldthan, Thomas Parker, Jack Gee, David Winslow, Kyle Astor, Timothy Brookbank
