Patent number: 8940057Abstract: A tubular casting liner for forming a definitive prosthetic socket includes an outer layer defining first and second surfaces and at least one polymeric layer having first and second surfaces. The first outer layer surface continuously defines at least a portion of the exterior surface of the casting liner, and the at least one polymeric layer first surface is secured to the second surface of the outer layer. A ratio of thickness of the at least one polymeric layer at the distal end area relative to the proximal end area is at least 3:1. The casting liner has a substantially straight profile, wherein a diameter d1 of the liner whereat the distal end area begins to transition to close-ended form is the same or substantially the same as a diameter d2 at the proximal end area. A method and kit for forming a definitive prosthetic socket may use the casting liner.Type: GrantFiled: January 10, 2012Date of Patent: January 27, 2015Assignee: Ossur HFInventor: Sigurdur Asgeirsson

Patent number: 8914813Abstract: Embodiments of this invention relate to an application program interface to enable browser extensions which may be executed in different browsers. In an embodiment, a browser extension may be written in using commands written in a cross-browser application program interface. When the browser extension is executed, the cross-browser commands may be translated into a native command of the browser. In an embodiment, the commands that require access to a document object model (DOM) of a page loaded in the browser may be executed on the thread that renders the loaded page. In a further embodiment the cross-browser application program interface may be, at least in part, an asynchronous interface. In this way, the cross-browser extension application program interface provides a stable, uniform interface to implement browser extensions that can operate in a plurality of different types of web browsers.Type: GrantFiled: April 9, 2010Date of Patent: December 16, 2014Assignee: Google Inc.Inventors: Johann Tomas Sigurdsson, Sigurdur Asgeirsson

Patent number: 8572066Abstract: A method for extracting content from a data store includes creating a file identifier mapped to an item. The method includes receiving a request that seeks cached access to the item and that is not directed to the item. In response to the request, contents of the item are provided using the file identifier without caching the contents. A system for extracting content from a data store includes an indexer. The system includes a data store containing at least an item. The system includes a redirector containing a file identifier mapped to the item.
