Abstract: Methods and apparatus, including computer program products, implementing techniques for document object model caching and validation. A client identifies a change of a user interface (UI) element that references a node of the DOM hierarchy. The client determines whether the change of the UI element can be applied to the DOM hierarchy by using an update function, for example, a delta renderer. If so, the client finds in the DOM hierarchy the node that is referenced by the UI element and modifies at least one attribute related to the node according to the change by using the update function. Otherwise, the client sets a dirty flag.

Abstract: A fastening element 30 is fed from a feed track 64 through a feed chamber, formed by interfacing closed channels 132 and 160, to a junction point located in a feed passage 84, formed by two communicating feed openings 86 and 88. An inclined surface 82, located between the feed chamber and the junction point, is inclined downward from the feed chamber to the junction point. A ram 105, located movably in the feed chamber, transfers the fastening element 30 from the feed track 64 to the inclined surface 82, where the fastening element moves down the inclined surface to the junction point. Upon the application of a pressure medium into the feed passage 84, selectively in either of two directions, the fastening element 30 can be directed toward a fastening device 104.

Abstract: An XML client abstraction layer for providing an XML page description as an abstraction of an HTML page at design time. A style sheet XSLT translator is used to derive the run time code from the XML page. Additional features or improvements may be added through an XML parser.

Abstract: A client-side framework for enhancing the functionality of web browsers. The client-side framework enhancing a client-side scripting language, such as JavaScript, so that it provides object-oriented features and enabling cross-window and cross-frame communications.

Abstract: Methods and apparatus, including computer program products, for processing a user interaction with an application, such as a browser-based application. A user interaction with the browser-based application is detected at a software framework. The browser-based application is executing in a browser at a local computer system. The user interaction is processed at the software framework, where processing includes determining whether the user interaction can be handled locally or requires access to a resource at a remote computer system. The user interaction is processed based on a result of the determination. A data item representative of the user interaction can be created at the software framework and stored at a data store. The data item can later be retrieved and the user interaction represented by the data item reprocessed at the software framework to replay the user interaction.

Abstract: A component installation tool of the type having a rearward stroke to accommodate delivery of a component to the front of the tool and a forward stroke to engage, deliver and install the component at a workpiece, the tool including a housing, a reciprocating mechanism contained therein, a feeder support mounted on the housing, a reciprocal magazine mounted on the feeder support for reciprocation between a component receiving position adjacent the tool and a position for delivering a component in front of the mechanism; and delivery means for delivering a component to a chamber in the magazine when the magazine is in the component receiving position and the mechanism is in the forward stroke.

Abstract: A rivet setting tool for use with double headed blind rivets comprises a collet assembly adapted to engage a pulling head of the rivet mandrel and support segments for engaging the rivet. A single piston drive pulls the collet assembly and the mandrel rearwards relative to the support segments and rivet to set the rivet. Continued movement of the piston further retracts the collet assembly and the support segments to permit delivery of a new rivet at the front of the tool and returns the collet assembly and support segments to a forward position in engagement, respectively, with the mandrel head and the rivet.
