Abstract: A computer system for creating and displaying a presentation is disclosed. In various embodiments, the computer system receives a request to generate one or more slides and to associate the one or more slides with a particular background. The system then displays a preview of the one or more slides and the associated particular background in a preview area. The system, in one or more embodiments, is configured to display, during the presentation, the one or more slides overlaid on the one or more backgrounds. In a particular embodiment, the computer system is configured to display multiple slides on a single background during the presentation.

Abstract: A system and method that allows a user to interactively display a presentation to one or more viewers. The presentation system allows the presentation to be displayed on an interactive display while one or more mobile computing devices assigned to each viewer connects to the presentation system so that the viewer can view the presentation and also receive one or more slides from the presentation in real-time while the slide presentation is being presented. The received slides may be electronically editable versions of the slides being displayed or electronically editable versions of slides that contain subject matter related to the subject matter of the slides being displayed. The viewers can edit the electronically editable versions of the slides and send the edited versions back to the user during the presentation. The user may then optionally display one or more of the edited slides as part of the presentation.

Abstract: A computer system for creating and displaying a presentation is disclosed. The computer system may receive a request to generate multiple presentation slides and to associate the slides with a particular background. Later, during a presentation, the system simultaneously displays the slides against the one or more backgrounds within a slide display area. The system may be configured to allow one or more users, during the presentation, to: (1) selectively annotate the slides; (2) save the annotations to memory for future use; (3) independently rotate and/or resize one or more of the first and second slides; (4) remove the first slide from the slide display area independently of the second slide; and/or (5) add one or more additional slides to the slide display area.

Abstract: A prefabricated roofing panel having an outer sheathing, rafters, insulation, and an interior ceiling material. The panel is configured to fit with other roofing panels to form the roof and ceiling structure of a building. Further the panel is ventilated. The roofing panel allows a building roof, insulation, and ceiling to be pre-fabricated in a shop and then quickly installed into a building.
