| 20110110767 | SEALED SHAFT ASSEMBLY FOR EXHAUST TURBINES - An exemplary assembly includes a component of a turbocharger that includes a bore that extends between an inner, exhaust gas side of the component and an outer, ambient side of the component; a shaft that includes a pin portion and a head portion; a sleeve positioned on the pin portion of the shaft; and a bushing positioned over at least part of the sleeve and over at least part of the head portion of the shaft where the bushing seats the shaft and the sleeve in the bore. During operation of a turbocharger that includes such an assembly, the shaft, the sleeve and the bushing restrict flow of exhaust gas from the inner, exhaust gas side of the component to the outer, ambient side of the component. Various other exemplary devices, assemblies, methods, etc., are also disclosed. | 05-12-2011 |

| 20110120125 | Locating Mechanism for Turbocharger Bearing - An exemplary semi-floating bearing for a turbocharger has a central axis defining a cylindrical coordinate system with an axial direction, a radial direction and an angular direction; a turbine end; a compressor end; journal surfaces between the turbine end and the compressor end, the surfaces configured to support a turbocharger shaft; and an opening disposed between the turbine end and the compressor end, the opening having a radial dimension that exceeds an axial dimension to, upon receipt of a locating pin, provide for movement of the bearing in the angular direction about its central axis and to provide for lesser movement of the bearing in the axial direction. Other exemplary bearings, arrangements and methods are also disclosed. | 05-26-2011 |

| 20090241648 | Reducing Noise In Atomic Force Microscopy Measurements - Exchanging data between an Atomic Force Microscopy (AFM) measuring device and an external controlling device using a wireless link. The wireless link replaces cables leading to the AFM measuring device and thereby mitigates mechanical noise vibrations. The controlling device can be an AFM controller, a PC workstation, a keyboard or a pointing device. A power supply and cables to provide power to the measuring device can be replaced with a battery power source to further mitigate mechanical noise. The AFM measuring device can reside in a vibration isolation chamber along with the power source and AFM controller to further isolate noise. | 10-01-2009 |
