Abstract: Enhanced user selection interface structures comprise one or more buttons that are linked to selectable characteristics, and a display linked to the buttons, for display of an item that corresponds to the selected characteristics. The interface is typically linked to a database comprising stored images and other information that corresponds to the selectable characteristics, wherein an image that corresponds to an item that meets a selected characteristic is retrieved and displayed. Corresponding information other than the image may also be retrieved and displayed. In some embodiments, the stored images comprise a single image that matches all the selected characteristics. In alternate embodiments, the displayed image comprises a composite image that corresponds to different selected characteristics. In some embodiments, the user selection interface comprises any of a graphic user interface or a mechanical interface.

Abstract: An Internet wire-mesh disc merchandising system embodiment of the present invention comprises a webserver that generates a web presence. Potential customers looking to select and buy wire mesh are allowed to log-on to a website operated by a wire-mesh retailer, distributor, and manufacturer. An HTML product page includes navigation buttons that link to other HTML product pages. Each page further includes JPG or GIF type pictures that allow the shopper to see a particular wire-mesh disc product corresponding to a presently displayed HTML product page. A set of navigation buttons permit the shopper to hyperlink to HTML product pages where a graphic is presented that corresponds to the selected wire-mesh disc and prices.

Abstract: A test fixture for integrated circuits, particularly those having large numbers of contacts. The fixture has a socket for receiving the integrated circuit, with conductive wad pins of the socket contacting lands or solderballs of the integrated circuit. Four clamping and alignment studs having peripheral grooves near their upper ends extend upward from the four corners of the socket. A lid is pivoted about a hinge pin which goes through bearing holes in the two studs and the lid. A pressure pad is resiliently suspended from the lid for applying pressure to the upper surface of an integrated circuit disposed in the socket. A slide-lock plate is mounted on the upper surface of the lid. A pressure pad screw extends from a position above the slide-lock plate, through a hole in the slide-lock plate, to engage threads of the central hole of the lid to apply pressure to the pressure pad when the pressure pad screw is rotated.
