Abstract: A system and method through which programming content is delivered for display on a network of electronic out-of-home display devices. The network includes a plurality of individually addressable display devices that are located in public venues. Demographic data is tracked for the display devices by place and by time so that the programming content can more closely conform to the changing demographic.

Abstract: An aircraft capable of sustained flight including a fuselage and a spiral-formed flat-section right hand and left hand wing positioned in generally horizontally opposing relation along either side of the fuselage. Each wing is formed of an elongated flat panel or plate having generally parallel leading and trailing edges, the length of the panel being substantially greater than its width, the width being substantially greater than its thickness. The forward and rearward ends of each wing are movably connected within forward and rearward longitudinal channels of the fuselage. By appropriate controlled linear and rotational movement of the wing ends, in combination with a conventional rudder of an upright rear stabilizer fin of the fuselage, all aerodynamic flight path variable control is accomplished. Both single and multiple spiral-turned wings are provided.
