Abstract: A semantic search engine is enhanced to employ user preferences to customize answer output by, for a first user, extracting user preferences and sentiment levels associated with a first question; receiving candidate answer results of a semantic search of the first question; weighting the candidate answer results according to the sentiment levels for each of the user preferences; and producing the selected candidate answers to the first user. Optionally, user preferences and sentiment levels may be accumulated over different questions for the same user, or over different users for similar questions. And, supplemental information may be retrieved relative to a user preference in order to further tune the weighting per the preferences and sentiment levels.

Abstract: Methods and devices for shielding electronic equipment within an enclosure are disclosed. One method includes positioning electronic equipment within an interior volume of a shielding enclosure having an opening providing access to the interior volume, the opening surrounded by an enclosure frame. The method further includes closing a door to the shielding enclosure, thereby closing off the opening, and engaging one or more latches to affix the door in a closed position, the door including a shielding curtain positioned across the opening. The method also includes inflating an inflatable member positioned along a perimeter of the door frame, thereby applying a uniform pressure to the shielding curtain toward the enclosure frame to form a seal therebetween.
