Abstract: The automatic building mapping system comprises a tracker module that can be carried by a user and an optional command module which operate to automatically map the rooms of a building as a user traverses the rooms of the building. The tracker module includes a transducer system that determines the present distance from the user to each of the walls of the room, the location of openings in the walls as well as an inertial guidance system that precisely locates the user with respect to a known reference point. The data produced by the tracker module of the automatic building mapping system can be transmitted to a centrally located command module so that multiple units can simultaneously be tracked and a mapping of the building effected from different perspectives to thereby create an accurate composite layout map.

Abstract: A method for creating a personal profile of a user for searching a database comprises the following steps: (a) words or words linked to graphical elements are presented as choices to a user in a display; (b) each word is associated with other keywords or default words; (c) if a profile of the user has previously been established, the profile is referenced for previous added keywords or associative words; (d) search phrases are made from selected keywords or associative words added to the profile; (e) the search phrases are sent as search queries to search for objects in the database; (f) the objects returned from the search are presented to the user as a new display of choices; (g) when a user selects an object, the words that were used to search for that object are added to the user's profile, or reinforced if already present; and the steps (d) to (g) above are repeated iteratively.
