  • Publication number: 20090087288
    Abstract: A substrate transport apparatus including a frame, a drive section connected to the frame and including at least one independently controllable motor, at least two substrate transport arms connected to the frame and comprising arm links arranged for supporting and transporting substrates, and a mechanical motion switch coupled to the at least one independently controllable motor and the at least two substrate transport arms for effecting the extension and retraction of one of the at least two substrate transport arms while the other one of the at least two substrate transport arms remains in a substantially retracted configuration.

  • Publication number: 20090033173
    Abstract: A motor includes a stator and a rotor, equipped to be movable in at least a first direction relative to the stator, the rotor operably interfacing the stator so that a motor force is generated in a first direction, where the stator comprises an anti-cogging element configured to generate anti-cogging forces on the rotor in at least the first direction and a second direction at an angle to the first direction.

  • Publication number: 20090015248
    Abstract: A sensing mechanism includes a magnetic source, a magnetic flux sensor, a sensor backing on which the magnetic source and flux sensor are mounted, and a ferromagnetic target, where the magnetic source, magnetic flux sensor, and ferromagnetic target are positioned to form a magnetic circuit from the magnetic source to the target, from the target to the sensor, and returning to the magnetic source through the sensor backing.

  • Publication number: 20070067678
    Abstract: A system for condition monitoring and fault diagnosis includes a data collection function that acquires time histories of selected variables for one or more of the components, a pre-processing function that calculates specified characteristics of the time histories, an analysis function for evaluating the characteristics to produce one or more hypotheses of a condition of the one or more components, and a reasoning function for determining the condition of the one or more components from the one or more hypotheses.

  • Patent number: 7119343
    Abstract: The present invention is directed to a scanning apparatus and method for processing a substrate, wherein the scanning apparatus comprises a first link and a second link rigidly coupled to one another at a first joint, wherein the first link and second link are rotatably coupled to a base portion by the first joint, therein defining a first axis. An end effector, whereon the substrate resides, is coupled to the first link. The second link is coupled to a first actuator via at least second joint. The first actuator is operable to translate the second joint with respect to the base portion, therein rotating the first and second links about the first axis and translating the substrate along a first scan path in an oscillatory manner. A controller is further operable to maintain a generally constant translational velocity of the end effector within a predetermined scanning range.
