20080243270 | Methods for predicting dimensional stability of a wood product based on differential characteristics - Methods are provided for predicting warp of a wood product given its differential characteristics, such as, for example, curvature. The methods may involve measuring at least one original warp profile for each of one or more first wood products; measuring one or more inputs on the one or more first wood products; converting the warp profile, for each of the one or more first wood products, into a differential characteristic profile; developing a prediction algorithm based on the one or more inputs and the differential characteristic profile; measuring one or more inputs of the given wood product; inputting the one or more inputs of the given wood product into the prediction algorithm; and determining a differential characteristic profile for the given wood product based on the prediction algorithm. | 10-02-2008 |
20080243271 | SYSTEM AND METHOD FOR QUANTIFYING AN IMPROVEMENT IN AN ADVANCED PROCESS CONTROL STRATEGY - An analysis application utilizes several quantitative metrics that characterize a controller's performance with respect to: specification limits, extreme values, and target and trend versus time. The application utilizes the metrics to provide statistical p-values. | 10-02-2008 |
20090055000 | SYSTEM AND METHOD FOR ROUTING SELECTION USING STATISTICAL DATA - A system, method, and medium, the method including receiving parameter information associated with a mailer, associating the parameter information with a mailing, receiving statistical information, the statistical information including historical performance data of at least one carrier, determining a delivery sequence for the mailing based on the received mailer parameter information and the statistical information, and outputting the determined delivery sequence for the mailing. | 02-26-2009 |
20090088873 | APPARATUS AND METHOD FOR THERMAL MANAGEMENT OF ELECTRONIC DEVICES - A system that incorporates teachings of the present disclosure may include, for example, a thermal management device having a controller to monitor pressure parameters for hot and cold rooms where the hot and cold rooms are divided by a rack for electronic devices and are substantially isolated from each other, and adjust a flow of cooling air to the cold room where the adjustment of the flow of cooling air to the cold room is based at least in part on the pressure parameters and maintaining a target pressure differential between the hot and cold rooms and where the target pressure differential induces a flow of the cooling air through one or more electronic devices in the rack. Other embodiments are disclosed. | 04-02-2009 |
20130060354 | METHOD AND SYSTEM FOR DETECTING AND CORRECTING PROBLEMATIC ADVANCED PROCESS CONTROL PARAMETERS - The invention may be embodied in a system and method for monitoring and controlling feedback control in a manufacturing process, such as an integrated circuit fabrication process. The process control parameters may include translation, rotation, magnification, dose and focus applied by a photolithographic scanner or stepper operating on silicon wafers. Overlay errors are used to compute measured parameters used in the feedback control process. Statistical parameters are computed, normalized and graphed on a common set of axes for at-a-glance comparison of measured parameters and process control parameters to facilitate the detection of problematic parameters. Parameter trends and context relaxation scenarios are also compared graphically. Feedback control parameters, such as EWMA lambdas, may be determined and used as feedback parameters for refining the APC model that computes adjustments to the process control parameters based on the measured parameters. | 03-07-2013 |
20140244002 | SYSTEM FOR MONITORING STATUS OF MODULES IN AN INDUSTRIAL CONTROLLER - An output module for an industrial controller configurable to simplify setup and commissioning is disclosed. The output module includes configurable PWM outputs that may be scheduled to start at different times within the PWM period, that may be configured to generate a fixed number of PWM pulses, and that may have an extendable PWM period. The output terminals are configurable to enter a first state upon generation of a fault and further configurable to enter a second state after a configurable time delay following the fault being generated. The output module may receive inputs signals directly from another module and set output signals at the terminals responsive to these signals. | 08-28-2014 |
