Abstract: A belt sander includes a frame, a drive roller, an idler roller rotatably attached to a pivot arm, a first linear actuator configured for pivoting the pivot arm, a nose roller and a continuous abrasive belt wrapped around the drive roller, the idler roller and the nose roller. A drive motor rotates the drive roller, and an air cylinder attached to the frame and a nose roller spindle exerts a first force against the frame and a second force equal to and opposite the first force against the nose roller spindle. A first sensor senses a position of a belt edge, and a first controller receives a belt edge position signal from the first sensor and sends a command signal responsive to the position signal to the first linear actuator for expanding or contracting so as to pivot the pivot arm about a pivot point.

Abstract: A universal software architecture for decision support includes an n-tiered architecture for building a universal task and workload management software system. The design incorporates a connectivity tier for activating a data object representative of application specific data; a management tier for activating a workflow object in response to both the data object and application specific rules; and a presentation tier for providing a user with decision support elements responsive to said workflow object. The design may also incorporate a corporate tier for providing the application specific data and rules.
