Abstract: An aerodynamic system comprising a torsion tube, a first rotatory coupling coupled to the torsion tube and adapted to mount to a first wheel hub, a second rotary coupling coupled to the torsion tube distal from the first rotary coupling and adapted to mount to a second wheel hub, and a non-rotating fairing panel mounted to the torsion tube.

Abstract: A chassis mounted energy extraction and delivery system. In one embodiment, a gravity-referenced, external tire inflation facility is integrated into an aerodynamic fairing mounted on the chassis of a vehicle. In one other embodiment, a torsion bar coupled between a hub-mounted energy extraction or delivery facility and a selected portion of the chassis provides a cross-referenced fixed point of reference. In a dual-axle embodiment, a first end of the torsion bar is coupled to the hub of one axle and a second end of the torsion bar is coupled to the hub of the other axle. In a single-axle embodiment, the second end of the torsion bar is coupled to the chassis.

Abstract: Retroreflective beads may be implanted into a coating applied to a surface of machinery to increase visibility of the machinery when a light source is directed at the machinery. A method of increasing the visibility of machinery includes applying a coating to a surface of the machinery. The coating may be a coating of paint, adhesive, or other material. The method also includes spraying the coating with beads before the coating sets to implant a portion of the beads in the coating without submerging the portion of the beads in the coating.
