  • Patent number: 7994662
    Abstract: The innovation relates to systems and methodologies for facilitating and/or enhancing heat transfer in a stage machine employed in an industrial or manufacturing environment. A thermal block and thermal rail combination and/or a thermal block and bearing rail combination draw accumulated heat away from a source of heat generated within the stage machine, and such combinations conduct the heat to a base of the stage machine. Each type of combination is conductively coupled such that the conductive coupling facilitates the translation or movement of the stage while maintaining contact to facilitate the conduction through the thermal block and thermal rail of the stage machine. The removal of the heat from the source of the heat or the accumulation of the heat within the stage machine system prevents distortion of the machine or products being manufactured or measured by the machine from the heat.

  • Patent number: 7528525
    Abstract: A system that facilitates damping of mechanical vibration associated with machinery that is subject to such mechanical vibration. The system comprises machinery with at least one moveable part and a piezoelectric actuator that is selectively applied to the machinery. The piezoelectric actuator receives voltages and is employed to facilitate damping of mechanical vibration associated with the machinery.

  • Publication number: 20090088912
    Abstract: Systems and methods of positioning a tool using a linear motor with a plurality of stages on a single path. A single rail and a plurality of trucks containing stages can comprise a linear motor. The trucks can connect to a tool through a linkage such as a four bar linkage or a scissor jack. The global position of the stages can be manipulated to effectuate motion along the path; the relative position, velocity, and acceleration of the trucks can be manipulated to effectuate motion in another direction such as a direction perpendicular to the path.

  • Patent number: 6715426
    Abstract: The present invention relates to a stability brake for absorbing parasitic vibrations of a stage moved to a working position in a motion system. The stability brake includes a motor coupled to a flexure plate through a translation system. The translation system translates horizontal motion of the motor into vertical motion of the flexure plate. The stability brake can be mounted to a stage in a motion system, such as a linear motion system. The stability brake is operative to absorb jitters and vibrations of the stage when the stage is moved to a working position in a motion system and held under servo at the working position.
