Abstract: A wheel cover system comprises a bracket adapted to mount to a hub of a vehicle, an alignment bushing coupled to the bracket, a piston, and a biasing member to bias the piston in an outboard direction. The alignment bushing defines an open area for receiving a tab of a disk assembly. The piston comprises a tab seating area and a rib, where the rib is aligned with the open area. The piston translatable in an inboard direction from a first position with the rib extending into the open area to a second position to create a clearance between the alignment bushing and the rib to allow the tab to be rotated from a position aligned with the rib to a tab position aligned with the tab seating area. The biasing member translates the piston to secure the tab in the tab seating area.

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 rollover prevention device couples a semi-trailer to a semi-tractor. The rollover prevention device comprises a top plate configured to be coupled to the semi-trailer and a bottom plate configured to be coupled to the semi-tractor. One or more frangible fasteners couple the top plate to the bottom plate. The rollover prevention device includes a controller coupled to one or more sensors, with the controller configured to determine a roll angle and a roll rate of the rollover prevention device. In response to determining the roll angle and/or the roll rate satisfy a rollover condition, the controller transmits a control signal to separable fasteners, which separate in response to the control signal allowing the top plate to detach from the bottom plate.

Abstract: Embodiments provide an aerodynamic fairing system that may comprise a base configured to mount to a vehicle, an arm coupled to the base at a proximate end and extending laterally, and a fairing mounted to the arm having an inboard and an outboard surface. The fairing outboard surface may provide an aerodynamic outer surface to direct flow to an angle to the rear. The arm may be a fixed or adjustable length arm. The arm may provide a mounting area for a mud flap such that aerodynamic system may act as a mud flap hanger. Embodiments also provide an adjustable mud flap hanger.

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: A system including a presentational layer with a graphical participant interface which receives data from a participate and passes said data to a workflow engine, a business logic layer including a computer processor, where the business logic layer receives payload data from said workflow engine and sends encrypted payload data to the data layer, and a data layer which includes a storage medium or combination of storage mediums including a blockchain, wherein said data layer receives encrypted payload data from said business logic layer and stores said encrypted payload data on the blockchain and on a shadowing relational database. The system generates dynamic accounting and bookkeeping methodologies without the use of a ledger by sequencing activity records of associated transaction participants, authorization provided to complete a transaction, and supporting documentation and processing them through a rule-based workflow engine.
