Patent number: 6273237Abstract: A semiconductor wafer pod payload platform is operable for rotation in response to linear movement of the platform by a cam assembly having rollers adapted to engage a cam surface. The payload platform is rotatably attached to a shuttle platform adapted for movement along linear rails. The shuttle platform is supported by shuttle glides adapted to move along the linear rails. A cam follower assembly is connected to the payload platform through a shaft extending through the shuttle platform and operable to rotate the payload platform. A cam surface substantially parallel to the linear rails is adapted to engage rollers on the cam follower assembly. Linear movement of the shuttle platform causes the rollers on the cam follower assembly to engage the cam surface and dispose the cam follower assembly so as to rotate the payload platform via rotation of the shaft.Type: GrantFiled: November 10, 1999Date of Patent: August 14, 2001Assignee: PRI Automation, Inc.Inventors: Kenneth J.

Patent number: 6265851Abstract: An ultracapacitor power supply for an electric vehicle is provided which employs an ultracapacitor as the primary power source and a battery as a supplemental power source. This vehicle is particularly effective in power-rail system having gaps in the power-rail or in non-power rail systems having recharging stations positioned along the track The ultracapacitor recharges quickly upon vehicle passage over a live power rail or entry into a recharging station. Optimum performance is achieved when the capacitor is allowed to fully recharge. The battery need only provide power when the ultracapacitor has been discharged or during acceleration or other periods of peak power consumption, thereby reducing the number of battery recharges required during any given operational period.Type: GrantFiled: June 12, 2000Date of Patent: July 24, 2001Assignee: PRI Automation, Inc.Inventors: Richard M.

Patent number: 6259221Abstract: A method and apparatus for tuning control loop parameters in a motion control system, is provided. In one embodiment, tuning of the proportional and integral gains of a servocontroller's velocity loop compensator is provided, as well as tuning of the cutoff frequencies of the servocontroller's low pass filters. In this embodiment, random noise excitation is added to the velocity command during a plurality of movement types for a machine tool axis. During each movement type, frequency response measurements are taken. Then, a composite frequency response can be selected by concatenating portions of the various frequency response measurements, so as to simulate a worst case scenario for the machine tool axis. From this composite response, an open loop response can be calculated and displayed, as well as bandwidth, phase margin, and gain margin values. The user can then enter the compensator parameters which were used when this data was taken, as well as proposed parameters.Type: GrantFiled: September 6, 2000Date of Patent: July 10, 2001Assignee: Siemens Energy & Automation, Inc.Inventor: Stephen J.

Patent number: 6257827Abstract: A method and apparatus for substrate processing at lower cost than existing processing systems are disclosed, which by implementing an arrangement using load locks of smaller dimensions or of a non-indexing type, as compared to existing large dimension or indexing load locks, along with a substrate loading and unloading technique can achieve the fast throughput of existing systems while reducing the size and cost of the load lock apparatus required. A processed substrate is returned by an internal robot from one of its processing modules to the shelf or slot in the small load lock from which the last substrate was removed for processing by the robot, rather than being returned to the original source shelf or slot from which it was removed for processing, as in the prior art. Also venting for a first one of the load locks is started as soon as the second load lock becomes the substrate source for the internal robot rather than waiting until the first load lock has been refilled with processed substrates.Type: GrantFiled: June 2, 1998Date of Patent: July 10, 2001Assignee: Brooks Automation Inc.Inventors: Ruth Ann Hendrickson, Peter F.
