Abstract: A control method and system for managing operations at a well. The well operation is divided into operating phases and a set of management requirements for each operating phase are established. An associate system for each discreet management requirement produces selected outputs based upon selected inputs from all the sensed dynamic variables as well as selected inputs from knowledge bases and models. Each associate displays real time functions depending upon the processing of any operating parameter, at the selected operating phase and discreet management requirement.

Abstract: A control section 20 incorporated in a coating/developing unit 2 is connected to a host computer 4, while a control section 30 incorporated in an exposure unit 3 is connected to the control section 30 of the coating/developing unit 2. Communication with the host computer 4 is performed by the coating/developing unit 2. The control of transfer of a wafer between the coating/developing unit and the exposure unit is executed using a timing signal which is independent of a process instruction output from the host computer 4. The host computer controls the coating/developing unit and the exposure unit using the control section of the coating/developing unit. Supply of instructions to the exposure unit 3 or collection of information therefrom is centrally controlled on the coating/developing unit 2 side.

Abstract: A human/machine interface for designing, monitoring and troubleshooting complex industrial control systems uses the paradigm of the factory floor to organize machines, control program portions and data as virtual spatially linked objects that may be moved in three dimensions to be joined with other spatially linked objects. The user may move within the virtual factory floor among the spatially linked objects followed by spatially indifferent objects which provide tools for monitoring and interacting with the spatially linked objects. Proximity of visual objects determines data sharing between objects.

Abstract: An image acquisition system for machine vision systems decouples image acquisition from the transmission of the image to a host processor by using a programmable imager controller to selectively disable and enable the transmission of data to the host and by using a system of buffers to temporarily store image data pending allocation of memory. This enables the image acquisition system to acquire images asynchronously and to change the exposure parameters on a frame-by-frame basis without the latency associated with the allocation of memory for storage of the acquired image. The system architecture of the invention further permits interruption and resumption of image acquisition with minimal likelihood of missing data. Data throughput is further enhanced by transmitting to the host only that data corresponding to the region of interest within the image and discarding the data from outside of the region of interest at the camera stage.

Abstract: A control system includes an Internet web interface to a network of at least one programmable logic control system running an application program for controlling output devices in response to status of input devices. The Web interface runs Web pages from an Ethernet board coupled directly to the PLC back plane and includes an HTTP protocol interpreter, a PLC back plane driver, a TCP/IP stack, and an Ethernet board kernel. The Web interface provides access to the PLC back plane by a user at a remote location through the Internet. The interface translates the industry standard Ethernet, TCP/IP and HTTP protocols used on the Internet into data recognizable to the PLC. Using this interface, the user can retrieve all pertinent data regarding the operation of the programmable logic controller system.

Abstract: A hot-plugging capability for video devices is achieved by shifting the responsibility for recognizing changes in the configuration of a display environment from a computer's operating system to a device manager. When an input/output device is added to or removed from the computer system, an interrupt signal informs a device manager of the fact that a change in configuration has occurred. In response thereto, the device manager determines whether the changed component relates to the computer's display function. If so, the device manager makes a call to the computer's display manager, to inform it of the fact that the display configuration has changed. In response to this call, the display manager reconfigures the display space for the computer system and notifies clients as appropriate, to accommodate display features associated with the added component. With this change in the configuration of the display space, the added component becomes immediately available for use.

Abstract: An on-line optimizer is comprised of a nonlinear dynamic model (702) which is operable to provide an estimation of the output of a plant. This receives manipulated variables (MV), disturbance variables (DV), and computed disturbance variables (CDB). The estimated output of the model is then compared to the actual output measured by virtual on-line analyzer (VOA) (616). This is compared is a difference block 618 to generate a bias which is then filtered by a filter(620). The output thereof is then provided to an output block (672) in a steady state optimizer (700) to offset the desired setpoints. These set points are input to a steady state nonlinear model which is operable to optimize the inputs to the plants for use for writing new set points in accordance with a predetermined cost function. This cost function is utilized to optimize the new inputs with the use of the steady state model in accordance with various constraints and target values.

Abstract: An apparatus and method for enabling an uncalibrated, model independent controller for a mechanical system using a dynamic quasi-Newton algorithm which incorporates velocity components of any moving system parameter(s) is provided. In the preferred embodiment, tracking of a moving target by a robot having multiple degrees of freedom is achieved using an uncalibrated model independent visual servo control. Model independent visual servo control is defined as using visual feedback to control a robot's servomotors without a precisely calibrated kinematic robot model or camera model. A processor updates a Jacobian and a controller provides control signals such that the robot's end effector is directed to a desired location relative to a target on a workpiece.

Abstract: The invention generally relates to various aspects of a plasma process, and more specifically the monitoring of such plasma processes. One aspect relates in at least some manner to calibrating or initializing a plasma monitoring assembly. This type of calibration may be used to address wavelength shifts, intensity shifts, or both associated with optical emissions data obtained on a plasma process. A calibration light may be directed at a window through which optical emissions data is being obtained to determine the effect, if any, that the inner surface of the window is having on the optical emissions data being obtained therethrough, the operation of the optical emissions data gathering device, or both. Another aspect relates in at least some manner to various types of evaluations which may be undertaken of a plasma process which was run, and more typically one which is currently being run, within the processing chamber.

Abstract: An industrial control system uses a number of autonomous control units, each associated with one piece of equipment in an industrial process. The autonomous control units include data indicating not only their constraints of operation but also reflecting the constraints of operation of machines to which they are attached and with which they share common operating parameters. An autonomous controller associated with a machine having operating parameters in common with another machine adopts the intersection of the ranges of the machine constraint of the two machines. Machine constraints are preserved to the extent possible as ranges so as to permit flexibility in selecting and seeking goals by the individual autonomous control units.

Abstract: A method suitable for producing a production plan that is feasible with respect to capacity availability. The method includes the steps of reading an end product demand and capacity availability information; selecting a specific demand derived from the end product demand and comprising an end product, a time period, and a quantity; determining whether the quantity can be produced in the time periods using the available capacity and surplus capacity from earlier periods; and, recording the amount of capacity used in each time period to produce this quantity; thereby enabling realization of end product demand when an imbalance of demand and capacity exists.

Abstract: A table of sequential call statements is used to organize various program portions of the operating system of an industrial controller. This organizing structure allows troubleshooting of individual program portions of the operating system as are intimately related to the controlled process and the control hardware on an individual basis without the need to generate dummy programs or “stubs” to replace the unexecuted program portions. Those program portions not being executed have their call instructions replaced by NOP instructions. The call table may be edited to provide for different operating modes of the industrial controller without the need for mode test flags otherwise dispersed within the program code of the operating system.

Abstract: A vacuum network controller includes a host interface for interfacing with a host controller, a component interface for interfacing with vacuum system components, a computer-readable medium storing software code, and a processor in communication with each of the preceding elements. The software code generates commands to control the vacuum system components, translates those commands into multiple communication protocols, and communicates the translated commands to the component interface. In a method embedded in a set of computer-translatable instructions, an instruction is received from a host controller. That instruction is processed to generate a command for controlling a vacuum system component. A software driver is selected from a library of drivers for communication protocols, and the selected software driver is used to translate the command into the respective protocol. Finally, the translated command is communicated to a component interface to control the operation of the vacuum system component.

Abstract: A mobile expert machine that moves along a nominal predefined trajectory. The expert machine should be a substitute for unskilled labor performed at workstations characterized by repetitive activities. An expert machine is defined as a machine that performs a specific task; the knowledge applied to the machine should be used to perform a repetitive task professionally. Predefined trajectory is defined as the actual trajectory that the slave expert machine should follow. The slave expert machine should move along a known predefined trajectory whose parameters have been calculated prior to start-up of the motion. It is assumed that the trajectory is given as function of time and the disturbances are well known. A Master Expert Machine (MEM) is incorporated with sensors for sensing and reading joint motions. It features excellent follow-up attributes and records motion activity in its memory by a process of “machine learning” within the study area.
