Patent number: 7328123Abstract: A monitoring method for a drive system with a motor and a moving part driven by the motor. The movement of the driven part is monitored and the movement of the driving part is monitored and compared to recognize a collision between the driven part and another structure. Measurement of at least one drive-side motion quantity of the motor is taken and measurement of at least one driven-side motion quantity of the moving part is taken. The motion quantity can be a position, velocity or acceleration. A dynamic model is calculated based on predetermined or expected operational data and the drive side measured data. An error signal is generated when the motion quantity measured on the driven side varies from the dynamic model.Type: GrantFiled: February 9, 2006Date of Patent: February 5, 2008Assignee: Durr Systems, Inc.Inventors: Sven Hooge, Dietmar Wildermuth

Patent number: 7322089Abstract: The present invention provides an enhanced method and apparatus for locating a valve stem aperture in a wheel. The invention includes a locating station having an overhead camera to scan the wheel. The scanned image of the wheel is received by a controller and is divided into radial zones. The controller locates the radial zone that defines the valve stem aperture from the scanned image of the wheel. The wheel then moves along an assembly line to a stemming station. A robot is positioned at the stemming station. The robot supports a valve stem insertion tool and a valve stem aperture locating sensor. When the wheel reaches the stemming station, the robot moves the valve stem insertion tool and the valve stem aperture locating sensor to the radial zone that defines the valve stem aperture. The robot moves the valve stem aperture locating sensor along the radial zone that defines the valve stem aperture and locates the valve stem aperture.Type: GrantFiled: May 14, 2004Date of Patent: January 29, 2008Assignee: Durr Systems, Inc.Inventors: Ben Giacona, Dan Pellerin, Brian Hoy, Eugene M.
