Abstract: A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.

Abstract: Described are a variety of techniques for viewing multimedia-based information in accordance with user controls for the speed and direction of the multimedia presentation. Different techniques for presenting multimedia data items are disclosed. User controls providing control for speed and direction in accordance with a user selection device being in a particular location. When a user device is with the defined area, the speed and direction control are on. When the user selection device leaves the defined area, the speed and direction are off. Also described is a system using a browser tool for displaying multimedia data in accordance with these viewing techniques. Multimedia data items displayed with the viewing techniques are indices into multimedia presentations. A user selection is made by viewing the multimedia data items and control is transferred accordingly to an appropriate application to present a multimedia presentation corresponding to a selected multimedia data item.

Abstract: A variety of techniques for both (1) viewing multimedia-based information in accordance with user controls for speed and direction of the multimedia presentation and in accordance with a user selection device being in a particular location and (2) presenting multimedia data items. When a user device is within the defined area, the speed and direction control are on, and when it leaves the defined area, the speed and direction are off. Also described is a system using a browser tool for displaying multimedia data in accordance with these viewing techniques which are indices into multimedia presentations. A user selection is made by viewing the multimedia data items and control is transferred accordingly to an appropriate application to present a multimedia presentation corresponding to a selected multimedia data item. An index database of the multimedia data items is used as indices into the multimedia presentations.
