Abstract: An improved retention mechanism having corresponding retention features is provided herein. The mechanism may include a pair of spring arm retention features in a connector receptacle engageable with a corresponding pair of recessed retention features in a connector tab and backup spring members for reducing stress within the spring arms during insertion of the tab and/or lubricating members for lubricating the retention mechanism. The backup spring is positioned adjacent an outer-facing surface or extends laterally outward from the spring arms so that deflection of the spring arms displaces the backup spring reducing stresses within each arm and/or increasing the retention force on the. The backup spring may include any or all of a bent portion of an bracket or arm, a wire, a loop, a complementary spring arm, dual backup springs, elastomeric members, compression springs and lubricating members. Methods of use and assembly such retention mechanisms are also provided.

Abstract: This is directed to a preview application for displaying several documents simultaneously in a single window, where the several documents are displayed as books. To view the pages of a document, the preview application can open the book and display the pages of the document (e.g., in a one or two-dimensional array). A user can also search for particular terms within the several documents. In response to a search, the preview application can filter the pages of the several documents and only display those pages that include the search terms. The displayed pages can be ordered in any suitable manner, including for example by search rank.
