20090231190	Electronic Tracking of Land Use Activities - Example systems and method described herein relate to electronic systems that allow land users to determine their location, determine the permitted activities for the specified location (based on day and hour) and communicate with land managers or other land users on permissions, conflicts or other issues. The example systems and methods will also allow land managers to track land users and communicate with them. In the examples shown, land users carry mobile devices that allow the land users to track their positions in relation to the geography of the land, as well as other land users. In addition, some examples described herein include devices that allow land owners or land managers to track land users and land use.	09-17-2009

20120008894	COMBINATION THRUST FLANGE AND THRUST PLATE - A thrust bearing assembly includes a single-piece thrust plate and thrust shaft flange having a generally cylindrical body portion, a frustoconical body portion and a bore extending through the cylindrical body portion and the frustoconical body portion. The bore defines a first bore section and a second bore section. A lip extends between the first and second bore sections. The first bore section, the second bore section and the lip are configured to receive a thrust shaft and axial thrust forces transmitted therefrom. The thrust bearing assembly also includes a bearing assembly in operable communication with the single-piece thrust plate and thrust shaft flange. The bearing assembly supports rotation of the thrust shaft and includes a plurality of first rolling elements. The bearing assembly includes a bearing cage to retain the first rolling elements and a plurality of second rolling elements disposed between the bearing cage and the thrust shaft.	01-12-2012
