  • Patent number: 8940057
    Abstract: 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.

  • Patent number: 8911506
    Abstract: A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, and having outer and inner surfaces. The liner sleeve includes an elongate, generally conical body portion formed from at least one material segment defining the liner outer surface. The at least one material segment being at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas. The liner sleeve includes a layer of polymeric material disposed on the at least one material segment and defining the liner sleeve inner surface, and a plurality of resilient seal elements protruding radially from the liner sleeve outer surface. The plurality of seal elements extend around at least one peripheral portion of the liner body portion. A pair of opposed annular recesses may be adjacently located above and below each of the at least one seal element.

  • Patent number: 8914813
    Abstract: 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.

  • Patent number: 8667480
    Abstract: Embodiments of invention relate to automatically updating browser extensions. In an embodiment, a method for updating browser extensions is provided. In the method, an input to execute a browser extension installed in a local browser extension database is received. In response to receipt of the input, a remote server is automatically communicated with to determine whether a portion of the browser extension should be updated. An updated portion of the browser extension is received if the browser extension should be updated. Finally, the updated portion of the browser extension is installed in the local browser extension database.

  • Patent number: 8572066
    Abstract: 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. When the redirector receives a request originated by the indexer that seeks cached access to the item and that is not directed to the item in the data store the redirector provides contents of the item using the file identifier without caching the contents in the system.

  • Patent number: 8177855
    Abstract: Embodiments of low cost prosthetic feet include a footplate with a connection mechanism embedded within a first foam element having a first stiffness. A second foam element is bonded to the footplate and has a recess in a proximal surface and a stiffness greater than the first foam element. The second foam element may have a portion extending past the terminal end of the footplate. A cosmesis encloses the components of the prosthetic foot. A third foam element that extends through the cosmesis into the second foam element may be provided. The third foam element may have a higher stiffness than the first and second foam elements.
