摘要:
A wheel assembly for a vehicle includes a rotatable wheel having a selectively adjustable steering angle. A steering actuator is operatively connected to the wheel and is configured to selectively adjust the steering angle of the wheel and not any other wheels. The wheel assembly allows independent control of the steering angle of the wheel. The wheel assembly also facilitates modular construction of vehicles by enabling the packaging of mechanical steering components in a preassembled wheel module with simple electrical connections to a vehicle chassis

A vehicle is capable of being driven in a plurality of forward directions, the direction of travel being a function of the forward-facing orientation of a movable seat or movement of the driver to a different seat. The vehicle includes a frame, at least three wheels, a steering system, a braking system and an energy conversion system operable with respect to at least one of the wheels and controllable through non-mechanical control means. The vehicle has at least one movable seat connected to the frame and at least one operator interface operably connected to at least one of the steering system, braking system and energy conversion system that is usable to drive the vehicle in different directions when the seat is moved. A control cockpit for use on a vehicle controllable through non-mechanical controls includes a panel with a passageway, a movable seat mounted on the panel with a second passageway in communication with the first passageway, a driver interface that is movable with respect to the seat and usable for operating the vehicle via a connector connected at one end to the driver interface and extending through the first and second passageways.

A soil stabilization system, method of stabilizing soil, and a stabilized soil having improved engineering characteristics such as increased bearing ratio and improved triaxial compression characteristics. Select embodiments comprise one or more lipophilic fluid mixtures, fibers which may be synthetic, natural or both, the lipophilic fluid and fibers mixed into soil of a pre-specified moisture content in pre-specified dry soil weight ratios. The system is optimized by adjusting the moisture content of the soil to a pre-specified figure prior to treatment, by compacting the treated soil to a pre-specified standard and finally by aging the resultant compacted treated soil for a pre-specified period to optimize engineering characteristics thereof. Select embodiments are suitable for use at temperatures approaching −60° F.

A door system includes a structural member and a door that is movably mounted with respect to the structural member for movement between an open position and a closed position. A spring is mounted with respect to the structural member or the door and being sufficiently positioned to bias the door toward its open position when the door is in its closed position. Active material based actuators may selectively compress the spring prior to door closure to minimize door closing effort.

摘要:
A heterogeneous mixture produced by blending aliphatic or cyclic organic compounds with carboxylic acids of chemical structure R-COOH and applied to soils in a manner to produce high levels of dust and erosion control, and soil stabilization. Alternatively, a heterogeneous mixture may be produced by blending aliphatic or cyclic organic compounds with polyolefins of chemical structure CnH2n or R—C2nH3n, and applied to soils in a manner to produce high levels of dust control and soil stabilization. The aliphatic and cyclic compounds act as plasticizers and carriers for the carboxylic acids or polyolefin compounds. When applied to soil the carrier provides a mechanism for the carboxylic acid or polyolefin to penetrate the soil and also acts as a dust suppressing weighting agent. The plasticized carboxylic acid and/or polyolefin provides a durable, reworkable binder that associates small particulates while stabilizing soil and aggregate.
