ActiveUS20120055367A1Improve performanceConvenient distanceMonorailsTrain hauling devicesCombustionInternal combustion engine
A personal transportation and freight delivery system that can be operated as a fully automated driverless land transportation system consisting of vehicles that move on their own propulsion on a pair of overhead parallel steel rails that form a single track and allows people to go anywhere the tracks can take them and delivery of freight anywhere along the tracks. Passengers and freight are transported inside a module that hangs from a propulsion dolly with in-line wheels to roll along such tracks. Electric motors are used for propulsion with power supplied at the tracks assembly; however, the system is also suited for internal combustion engines. There's no need for track switches to route vehicles to its destination as each vehicle has a steering mechanism. Rubber bumpers at each end of the propulsion dollies allow the vehicles to fit bumper-to-bumper along the tracks.

Adjustable air suspension shocks with rotatable damper assemblies, apparatus, systems and method for motor vehicles, such as automobiles, vans, trucks, off the road vehicles, motorcycles, the like. Deflating interior air springs / airbags (bladders) allows for pistons on shock absorbers to expand outward separating lower front and rear frame portions which effectively lowers the motor vehicle to the ground surface and for the driver to have a firmer ride. Inflating the airbags (bladders) allows for the pistons on the shock absorbers in the devices to retract so that devices have a more shock absorbing effect giving the driver and passenger(s) a smoother ride, which also raises the motor vehicles above the ground surface. A sleeve attached to the air shock allows for a damper assembly to rotate relative to the air shock so that it can be installed within mounting brackets where the axial mounting openings need not be perpendicular to one another.
