Abstract: Combustion variables are diagnosed using sensors to measure turbulence in the post-flame zone as well as in the flame envelope of a combustor. Output signals from the sensors are processed and a set of statistical functions are calculated which are correlated with specific combustion variables, such as the concentration of unburned carbon in fly ash. A special sensor mounting box provides reliable long-term operation in harsh combustor environment, without a supply of cooling or protective air flow.

Abstract: A generic process control routine for a process control system is written to include alias names and dynamic reference parameters. Before execution of a process control function on a particular unit of the process control system, an instance of the generic routine is created, in which the alias names are replaced by parameters defined in an alias resolution table for the particular unit. The controller then executes the instantiated version of the generic routine to control operation of the unit. The generic routine can have multiple algorithms associated therewith, wherein each of the algorithms is designed to control different units having somewhat different hardware, even though these different units perform essentially the same function within the process control system. The generic routine may also be used with multiple classes of hardware that perform different functions within the process control system.

Abstract: The invention described herein includes a method of testing an analyte such as urine to determine whether the analyte contains specific substances such as drugs of abuse. An on-site screening test provides a preliminary test result either by visual or machine analysis of a screening test device, and the result and user data are entered on a provided form. An electronic image of the form is sent to a central data location, where it is received and the data on the form is recognized by machine and stored. If the on-site screening test provided a nonnegative result a sample is sent to a laboratory for further testing, and if the test provides only negative results no further testing is done. The testing laboratory performs further testing for verification of nonnegative screening test results, and all data is collected at the central data location. Results are then reported to the client or whoever the client designates to receive test results.

Abstract: A computer-implemented molecular dynamics-based process simulates a distribution of ions implanted in a semiconductor substrate. The properties of the semiconductor substrate and ion dose to be simulated are first initialized, including an initial set of splitting depths that contain an equal number of virtual ions implanted in each substrate volume determined by the splitting depths. A first ion with selected velocity is input onto an impact position of the substrate that defines a first domain for the first ion during a first timestep, where the first domain includes only those atoms of the substrate that exert a force on the ion. A first position and velocity of the first ion is determined after the first timestep and a second domain of the first ion is formed at the first position. The first ion is split into first and second virtual ions if the first ion has passed through a splitting interval. The process then follows each virtual ion until all of the virtual ions have come to rest.

These parameters are then used in processing a second workpiece, which may be similarly measured, and the results used to further refine the parameters.

Abstract: Object services like methods or properties are provided to or inherited by objects dynamically during run-time. In one method of providing dynamic inheritance, hierarchical relationships are defined between multiple objects such that each object references or is referenced by another object. A call is made for a particular service (e.g., a method or property) at a selected object. The service is provided directly from the object whenever the service is available therefrom. Whenever the selected service is unavailable at the selected object, the call is passed to a hierarchically superior object. Another aspect of dynamic inheritance is that an object, such as the root object, may include one or more methods for adding or otherwise changing the methods or properties available from that object.

Abstract: By monitoring the output voltage of a mass flow controller (MFC) there is no way to detect when a MFC is starting to degrade (or beginning to fail) as long as the MFC output voltage is driven to match the MFC setpoint voltage. Only when the MFC actually fails, and the MFC output voltage is unable to be driven to match the MFC setpoint voltage, is the failure detectable. A predictive failure monitoring system for a mass flow controller (MFC) is disclosed which monitors the “valve voltage” of the MFC as well as the MFC output voltage. By knowing the normal relationship between the MFC setpoint voltage and the respective valve voltage, then degradation or other changes may be noticed before the MFC actually fails, and importantly, before production material is ruined by the failing MFC. Such a real-time monitoring capability may be transparently implemented as an add-on module between the MFC and the system controller for the MFC.

The data processing start signal is sent to the data processor which starts the data processing in response to this signal.

Abstract: Formation of calcium sulfite in a desulfurization column for desulfurizing flue gas is prevented by maintaining the pH of the sorption liquid in the column in the range of 5.5-7.0 and the chemical oxygen demand of the sorption liquid below an upper value determined by the concentration of magnesium sulfate. The upper value of the chemical oxygen demand of the sorption liquid can be controlled by maintaining the quantity of magnesium sulfate in an oxidization vessel arranged downstream of the desulfurization column. The oxidized liquid discharged from the oxidization vessel is neutralized in a double composition vessel, and the thus-obtained slurry is returned directly to the desulfurization column. By preventing formation of calcium sulfite, high-quality gypsum is formed in the double composition vessel.

Abstract: One or both of two methods and systems are used to determine concentration of a known material in an unknown mixture on the basis of the measured interaction of electromagnetic waves upon the mixture. One technique is to utilize a multivariate analysis patch technique to develop a library of optimized patches of spectral signatures of known materials containing only those pixels most descriptive of the known materials by an evolutionary algorithm. Identity and concentration of the known materials within the unknown mixture is then determined by minimizing the residuals between the measurements from the library of optimized patches and the measurements from the same pixels from the unknown mixture. Another technique is to train a neural network by the genetic algorithm to determine the identity and concentration of known materials in the unknown mixture. The two techniques may be combined into an expert system providing cross checks for accuracy.
