Abstract: A vehicle-to-vehicle power transfer system for use between a first vehicle and at least a second vehicle. The system includes an electric power system disposed in each of the first and second vehicles configured to provide electrical drive power to a vehicle drive system for propulsion of the associated vehicle and a power transfer system configured to transfer electric power from at least the electric power system of the first vehicle to the electric power system of the second vehicle while the vehicles are in motion or stationary.

Abstract: A rotationally compliant bearing roller assembly having a roller, at least one bearing member operably coupled to a base configured to support rotational movement about a rotational axis; and a rotary compliant joint interconnecting the at least one bearing member to the roller. The rotary compliant joint having a first compliance in a rotational direction about the rotational axis to permit movement of the roller in the rotational direction relative to the at least one bearing member, such that the first compliance being greater than a friction induced compliance of the at least one bearing member in the rotational direction. The compliant joint having a second compliance in a direction orthogonal to the rotational direction, such that the second compliance being less than the first compliance.

Abstract: An axially compliant rolling bearing for precision motion stages having a stage, at least one bearing member slidably disposed along a rail, and a compliant joint interconnecting the at least one roller bearing to the stage. The compliant joint is sufficiently compliant to permit movement of the stage in the axial direction while remaining stiff in other directions orthogonal to the axial direction.

Abstract: A vibration-assisted positioning stage comprising a stage, a roller bearing, an compliant joint interconnecting the roller bearing to the stage such that the compliant joint is sufficiently compliant in a direction of movement to permit reliable alignment of the stage and further permit dithering, and a dithering force actuator applying a dithering force directly to the roller bearing to permit the dithering of the stage. The dithering forces can be applied out of phase to minimize vibration of the stage. Furthermore, the controller of the stage can be employed to suppress any remnant vibrations of the stage due to dithering. A supervisory control system can intelligently adapt the parameters of the dithering signal to optimize the performance of the stage as friction changes.

Abstract: A magnet assisted stage system for scanning applications having a scanning table being moveable from a first position to a second position, a scanning actuator operably associated with the scanning table to move the scanning table along a scanning direction from the first position to the second position, and an actively variable magnetic spring system being operably augmented to the scanning table to exert a magnetic repulsion force upon the scanning table in the scanning direction.
