Abstract: A slotted crossbar may include an upper slot and a lower slot running continuously across the entire length of the crossbar. Internal channels associated with the upper and lower slots may be structurally independent, such that a floor of the upper channel is spaced from a ceiling of the lower channel. An illustrative slotted crossbar may be manufactured using an aluminum extrusion process.

Abstract: A selectable pitch crossbar-to-vehicle coupler may include a crossbar clamp having a first mating surface that is selectively receivable on a second mating surface of the coupler in a plurality of discrete orientations. Each of the discrete orientations may correspond to a respective angle of the crossbar relative to the coupler. The angle may be a pitch angle.

Abstract: A seismic expansion joint cover assembly installed at an expansion gap between a first structural member on one side of a gap and a second structural member on the opposite side of the gap including a cover panel bridging the gap having at least one connector joining one edge of the cover panel to the first structural component to allow movement of the cover panel. The expansion joint cover assembly includes at least one slide support, which attaches to the second structural member, and which includes a track having a lift component located on the track to lift the cover panel. The expansion joint cover assembly also includes a rider assembly for engaging with the track of the slide support. One or more spring assemblies are attached to the second structural member and the cover panel. The expansion joint cover assembly is mechanically latched when the system is in the normal service position, but has the capability of becoming unlatched in response to large displacements.

Abstract: The present invention provides a system and method for providing flight information data to an airport. A flight information provider collects airline-specific flight information data from several airlines. The airline-specific flight information is then processed by the flight information provider to generate airport-specific flight information containing flight information for flights arriving at and departing from each airport. Web pages are then generated for each airport containing the airport-specific flight information for that airport. The web pages are then transmitted to the airports for display on monitors in the airports.
