  • Patent number: 10766526
    Abstract: A steering system and method is described for a vehicle having steerable front and rear wheels, and a steering input device for receiving manual steering input. Front and rear hydraulic steering devices may be coupled, respectively, to the front and rear wheels. Front and rear valve assemblies may be configured, respectively, to steer the front and rear wheels. In a manual steering mode, the front valve assembly may be disabled with respect to the front steering device, and the front hydraulic steering device may steer the front wheels based upon the manual steering input. In a rear steering assist mode, a rear steering command may be determined based upon the manual steering input, and the rear wheels steered based upon the rear steering command. In an automated steering mode, the front and rear wheels may be automatically steered based upon a target path of travel for the vehicle.

  • Patent number: 10518804
    Abstract: A steering system and method for a vehicle having steerable front and rear wheels has rear hydraulic steering device that may be coupled to one or more of the rear wheels. A rear valve assembly may hydraulically control the rear hydraulic steering device to steer the rear wheels based upon a rear steering command from a controller. In a manual steering mode, the controller does not determine a rear steering command for the rear valve assembly such that the rear wheels are freely rotatable. In a rear steering assist mode, the controller determines the rear steering command based upon, at least in part, the manual steering input.

  • Patent number: 7625548
    Abstract: Liquid nanoscale particle precursor materials for generating nanoscale particles include at least one high volatility carrier and a second component. A nanoscale particle generating device generates nanoscale particles by passing a liquid nanoscale particle precursor material through a flow passage heated to convert the carrier into a vapor and the second component into nanoscale particles. The nanoscale particles preferably consist essentially of the second component and can consist essentially of dry, solid particles. The particle generator can be incorporated in a hand held inhaler, and can be delivered to a targeted portion of the lung using the inhaler. Composite controlled release particles of micron or nanoscale size can be produced by flowing a solution of medicament, control release agent and carrier liquid through a capillary heater.
