Patent number: 7178767Abstract: A multi-leg equipment stand has a unitary user interface. All legs can be adjusted simultaneously, or, an individual leg can be adjusted, by distinct motions of the interface. A collar is near to an equipment support shoulder. Rotation around a vertical axis releases all legs. For a tripod, tilting the collar in one direction releases only one of three legs. The tilt may be toward the leg to be moved. The legs have adjacent, telescoping components. A control rod extends from the collar, through the hollow interior of the upper component, to a jam-plate, at the lower end of the upper component. The plate jams between an inside of the lower component, and an inside of the upper component. The rod passes through the jam-plate. Pushing the rod tilts the jam-plate, freeing it from jamming. A spring returns it to jamming if released. For each leg, the collar underside has a two level cam recess. The rods each have a cam follower surface at their shoulder end.Type: GrantFiled: May 9, 2002Date of Patent: February 20, 2007Assignee: Massachusetts Institute of TechnologyInventors: Jasper L. Steyn, Daniel K. Moon, Brian B. Conaty, Thomas A. Greenwood, Ingrid Shao-Ying Huang, Philip G. Kong, James I. Meyer, Prabhat K. Sinha

Patent number: 6980881Abstract: Large machines, especially those having working envelopes in excess of fifteen feet, exhibit unacceptable errors because of thermal expansion and mechanical misalignments between the axes. The errors have traditionally been minimized by enclosing the machine in a thermal enclosure, by careful calibration, or by mounting a laser interferometer on each axis. These solutions are costly, may require frequent recalibration, and do not correct for small rotations of one axis relative to another axis due to wear etc. The present invention uses an interferometric laser tracker or a comparable 3D position sensor to measure the position of a retroreflector attached to the end effector, e.g. a machine head when the machine comes to rest. A computer compares the measured position to the desired position according to the machine media, and adds the appropriate correction with trickle feed media statements to move the machine to the correct position prior to further machining.Type: GrantFiled: August 20, 2003Date of Patent: December 27, 2005Assignee: The Boeing CompanyInventors: Thomas A. Greenwood, Thomas W. Pastusak

Patent number: 6420694Abstract: A steerable retroreflective system is disclosed that includes a retroreflector that reflects at least some light incident upon the retroreflector, while permitting at least some of the incident light to leak therethrough. The steerable retroreflective system also includes an optical detector that detects leakage light that passes through the retroreflector. The steerable retroreflective system further includes means for controllably steering the retroreflector in response to the leakage light detected by the optical detector, such as to track the incident light. The method of controllably steering the retroreflector is also disclosed. The steerable retroreflective system and method therefore provides a retroreflective target with a much wider acceptance angle than conventional retroreflective targets.Type: GrantFiled: September 21, 1999Date of Patent: July 16, 2002Assignee: The Boeing CompanyInventor: Thomas A. Greenwood

Patent number: 6392222Abstract: A machine system having optical endpoint control and an associated method for monitoring the position of a machine are provided which includes at least one steerable retroreflective system that defines a relatively large effective acceptance angle, typically exceeding 320°. In particular, the machine system includes a machine capable of movement in at least one direction and a steerable retroreflective system mounted upon the machine, such as upon the end effector of the machine, for movement therewith. The machine system also includes at least one light source for illuminating the retroreflector such that the position of at least a portion of the machine is determinable based upon reflections from the retroreflector. As such, the machine system can make any necessary corrections in the computer control of the machine to accommodate for differences between the anticipated position of the machine and the actual position of the machine.Type: GrantFiled: September 21, 1999Date of Patent: May 21, 2002Assignee: The Boeing CompanyInventor: Thomas A.
