Abstract: Some information retrieval systems, such as the Westlaw™ system, empower users to search thousands of databases. One problem with some systems is that the large number of databases makes it difficult for some users to identify the right database(s) to search. Thus, the inventors devised, among other things, new options for helping users target searches on the right databases. One option enables users to search sample-based database profiles. Another enables users to navigate to a category or subcategory in an online database directory and search databases or database profiles associated with the category. And, yet another enables users to select a query-category and receive a list of relevant database choices, a list of links into a database directory, or a sequence of follow-up questions. One or more of these or other disclosed innovations enable users to execute more effective search strategies, while potentially reducing computational burdens on information retrieval systems.

Abstract: A high density interconnect system is described which comprises a laminated board including a conductive power plane and a ground plane insulated from each other and containing a series of holes therethrough. Signal contacts, ground contacts, power contacts, data bus interconnect contacts, and feed-through contacts are selectively mounted in the series of holes with the ground contacts and power contacts connected to the respective ground plane and conductive power plane and the other contacts insulated therefrom. Front contact housings are secured against the laminated board means and contain spring-loaded contacts in openings therein for electrical engagement with the signal contacts and for electrical engagement with pins of a signature board.

Abstract: A modular plug board system is disclosed for interconnecting an array of parallel cards in a card cage. The cards are pluggably connected to the IO circuit board of a machine to be programmed by the plug board system. A rear board of the plug board system is divided into sections which impinge one another in side to side relationship. The sections are pluggably connected to corresponding cards and are individually removable from the plug board system to allow for individual removal of the cards from the card cage and from pluggable connection with the IO circuit board. One or more cards may be eliminated from the card cage to allow for discrete wire or cable connection directly from the IO circuit board to an appropriate section of the plug board system.
