Abstract: An automatic portable inspection system includes a part holder for holding a component to be inspected and a rotary actuator coupled to the part holder. The system further includes an eddy current probe for scanning the component and providing eddy current signals. The system also includes a self-alignment unit coupled to the eddy current probe and configured to align an axis of the probe substantially perpendicular to a surface of the component and to maintain constant contact with said surface of the component. The system also includes a linear actuator coupled to the self-alignment unit, for providing movement of the eddy current probe along the X, Y and Z axes. A motion control unit is coupled to the rotary actuator and the linear actuator, for controlling the rotary actuator and the linear actuator for moving said probe about the component in accordance with a scan plan.

Abstract: X-ray source bearing assemblies are described herein. In an exemplary embodiment, an x-ray source includes a target anode, a rotor shaft coupled to the target anode, and a motor coupled to the rotor shaft at an end of the shaft opposite the target anode. The bearing housing, in the exemplary embodiment, includes a rotor bore, the rotor shaft extending through said rotor bore and supported therein by a plurality bearings. The housing and the shaft form a cooling medium pool so that as the shaft rotates, a cooling medium in the pool is radially displaced.

Abstract: The present invention provides, in one embodiment, a bearing assembly consisting of a rotatable shaft and a stator coaxially aligned. The stator has at least one circumferential protrusion that contains respective segments that extend radially from the stator. Each of the respective segments contains at least one capture cavity and has a main cavity disposed between each of the respective segments so as to house a thermal shunt. A plurality of roller bearings are also disposed radially between the rotatable shaft and the stator. In addition, at least one viscoseal is disposed on the rotatable shaft.
