| 20080236328 | Steering Wheel Mounting Assembly - A steering wheel mounting assembly comprising first and second stationary rings, the second stationary ring being adapted for connection to a vehicle frame. The assembly further comprises a steering hub having a spindle with a radial flange extending therefrom. The spindle is adapted for connection with a steering shaft and the radial flange is adapted for connection with a steering wheel. The spindle has a first bearing raceway for engaging a bearing of the first stationary ring and a second bearing raceway for engaging a bearing of the second stationary ring. The steering hub has at least one opening that defines a bearing surface. A friction roller assembly, having a shaft with a third bearing thereabout, is positioned in the opening such that as the third bearing rotates relative to the bearing surface, the third bearing moves radially outward and the shaft engages the first and second cylindrical raceways. | 10-02-2008 |

| 20090093961 | ANALYSIS OF TIME-SERIES DATA USING SINGULARITIES - A method for acquiring and analyzing time-series data using singularities is described. This method allows for the analysis of data over a wide spectrum of frequencies. Once the data is acquired in an oil field, singularities of the data are extracted; and the extracted singularities are utilized to interpret the formation properties related to the data. | 04-09-2009 |

| 20110203846 | METHOD AND APPARATUS FOR SEISMIC DATA ACQUISITION DURING DRILLING OPERATIONS - An apparatus and method are provided for obtaining formation data while drilling. The apparatus may include a drill string and a plurality of sensors. At least two of the plurality of sensors are spaced apart along the drill string a approximately the same distance as a length of a segment of the drill string. The segment of the drill string is either added to or removed from the rest of the drill string as the drill string moves in the borehole during a drilling operation. The method may include providing numerous sensors along a drill string and repeating a cycle of various functions. The cycle may include performing an operation moving the drill string relative to the borehole and stopping movement of the drill string. Additional functions may include changing an overall length of the drill string and performing the formation property while the drill string is relatively stationary. | 08-25-2011 |
