Abstract: A cross bar for mounting a vehicle topper to a roof of a vehicle is provided. A center section has a rectangular cross section, a first end, and a second end. A first tapered section extends from the first end of the center section. A second tapered section extends from the second end of the center section. A longitudinal axis of the center section, the first tapered section, and the second tapered section extend primarily in the same direction.

Abstract: A system and method for monitoring air quality is disclosed. A housing for an electronic display has a first pathway which extends between an ingestion area and an exhaustion area. An air quality monitoring device is located along said pathway and has one or more sensors that measure the concentration of various gases. The air quality monitoring device has a housing with a second pathway which connects an entrance aperture to exit aperture. The entrance aperture being configured to permit a portion of the ambient air in the first pathway to enter the second pathway.

Abstract: A roof mounted vehicle topper includes an electronic display, a housing for said electronic display, and a cross bar. The housing is mounted to the cross bar which is configured for mounting to the roof of a vehicle. At least a portion of the cross bar is hollow. A power source for said electronic display is located outside of said housing. Electrical wiring extends from said power source, through the hollow portion of said cross bar, to the electronic display.

Abstract: A cross bar for mounting a vehicle topper to a roof of a vehicle has a center section with a substantially rectangular cross section. Tapered sections are attached at a proximal end to each side of the center section. Outer plates are located on the distal end of each respective tapered section. The tapered sections increase in cross sectional area from their distal end to their proximal end.

Abstract: A system and method for redundant multi-panel display is provided. A first system control board is electrically connected to the first electronic display and a first video player. A second system control board is electrically connected to the second electronic display, the first video player, and a second video player. The second system control board is configured to begin utilizing the first video player upon failure of the second video player. Order information is received from a point of sale data output and transmitted to at least one of the first system control board and the second system control board. The first and second video players are configured to cause background images to blended with the order information and displayed on the respective electronic display.

Abstract: An electronic display is controlled by a timing and control board and normally displays background image data. The timing and control board is electrically connected to a system control board that is configured to receive order confirmation data from a point of sale data output. A video player is electrically connected to the system control board and is configured to blend the order confirmation data with the background image data. The blended image is transmitted to timing and control board and displayed on the electronic display after an order is placed.
