Abstract: A light air-cushion vehicle has a thrust reverser bucket arranged at an output end of an air nozzle, at least one direction rudder having control surfaces at the output end of the air nozzle and at least one direction rudder having control surfaces in a lift contour, a control system for the thrust reverser bucket and a control system for the direction rudders. The direction rudders are kinematically connected to each other and to a steering device. The control surfaces at the output end of the air nozzle turn around an axis in the vertical direction and the control surfaces in the lift contour turn around an axis in the longitudinal direction axis.

Abstract: A platform wheeled apparatus that incorporates an intelligent wheel configuration for each wheel in which each wheel can dynamically change its radius to negotiate various obstacles. The intelligent wheel has a rotational hub and support disc that carries a series of arcuately spaced extendable, weight bearing radial spoke mechanisms that can be controllably extended and retracted in response to the anticipated terrain surface over which the wheel is to travel. The hub of the intelligent wheel carries a microcontroller for a set of obstacle proximity sensors, force and position sensors and an appropriate electrical power supply for operation of the spokes and control components.

Abstract: A track assembly having first and second hub assemblies that are operatively connected to a support frame by first and second attachment members, respectively. The first and second attachment members include resilient or movable mounts that are configured so that the track assembly can be attached to vehicles whose axles or wheel flanges are misaligned or have irregular rotational movement such as runout or wobble. The attachment members may be adjustably positioned relative to the support frame to accommodate vehicles having different wheelbase lengths and axle lengths. An endless track encircles the first and second hub assemblies, and the support frame, and is drivingly engaged by one of the hub assemblies. First and second rollers, which define the longitudinal extent of the endless track, are positioned at either end of the support frame. A tensioning member, with at least one upper idler roller, positions the endless track so that it is spaced from one of the hub assemblies in a spaced relation.
