The determines process model parameters for a simple and complex model of the process and uses those parameters along with the value of the process variable and the final control element position to predict the off control data. The method also uses the process model parameters to determine the optimal tuning and then forecasts the optimal process performance from the predicted off control data and the determined optimal tuning.

Abstract: An edge gripping device grips and ungrips a substrate, such as a semiconductor wafer. A blade extends in a distal direction from a base of the device. At least one distal contact member is provided at the tip of the blade. Two proximal lever arms are pivotally coupled for synchronized, oppositely directed rotation to the base. Each lever arm has at least one proximal contact member at an outer end. A biasing member is coupled to the two proximal lever arms and to an actuator to effect pivoting movement of the lever arms. The pivoting motion moves the ends of the arms generally radially toward and away from the center of the substrate to be gripped or ungripped, thereby minimizing sliding of the substrate. The biasing member is biased to retain the lever arms in a closed position in the event of a power failure. Ramps are provided next to each contact member. The contact members and ramps are profiled to minimize the zone of the substrate edge that is contacted.

Abstract: Disclosed is a vehicle which includes an electrical system monitoring system which results in detecting arcing in the electrical distribution system of the vehicle and the ability to provide notification and protection for such arcing. The system functions to monitor the electrical distribution system of the vehicle to sense the frequencies of signals in the system using appropriate filtering. One type of filtering which may be used is based upon a heterodyning circuit which provides variable frequency filtering for filtering a signal representative of the current in at least one electrical circuit of the vehicle. The heterodyning circuit output is configured to produce a signal which may be logarithmically related to the filtered signal. If the output signal exceeds a predetermined limit (representative of noise) for a predetermined period (representative of a typical arc duration), the system generates an arc signal.

Abstract: An automated image recording and document generation system is disclosed that generates identity documents using image and text information that is input to the system using computer controlled video cameras. The image and text information is combined with other stored images, such as logos, signatures and seals, to produce official identity documents such as identity cards, drivers licenses and passports. Prior to use the system automatically enters a setup and calibration phase wherein a video camera images a backdrop having borders on the left and right vertical edges and the digitized video output is analyzed to adjust the camera zoom and to locate the center of the backdrop in front of which an individual will sit or stand to have their picture taken. The image of a person whose picture is taken is analyzed and is centered horizontally in a picture by adding or subtracting columns of background color to the left or right side of the picture as needed.

Abstract: For a web color change, at least one current dye rate is determined and at least one nominal dye rate for the new web color is retrieved. The difference between the current dye rate and the nominal dye rate is used in a dye rate change response to change the dye rate thereby changing the web color from a first to a second color. The dry rate change response is boosted to achieve a faster rate of color change. Dye rates required for color targets are determined by accumulating historical data of production dye rates that are combined with current dye rate data to arrive at new nominal dye rates for web colors to be produced. A retrieved nominal dye rate and the current dye rate are combined using a filter factor, &agr;, (0≦&agr;≦1), defining the fraction of the historical dye rate which is combined with the remaining fraction of the active dye rate to determine a new nominal dye rate stored as the nominal dye rate for the given product color.
