In a method for the analysis of process data of an industrial plant, in particular a power station plant, parts of the plant are automatically controlled for the purpose of information compression, filtering and diagnosing faults in good time. Features characterizing the plant process are first prescribed and parameters relevant to the plant process are provided. Subsequently, the presence of each feature is checked for each plant part by using the parameters. Correlations between combinations o…

A concrete paving system of a variety employing an array of vibrators which consolidate dispersed concrete over a roadbed or the like as the concrete is introduced to the mouth of a slipform pan or mold. The rate of vibration of these vibrators is monitored utilizing an accelerometer in conjunction with a vibration conversion network treating the acceleration signals to deriving vibration rate data which is published for each vibrator at a display. A controller with the system provides for the d…

A fluid dispensing control for controlling the dispensing of a fluid by a metering valve through a nozzle onto a workpiece. An initial value of a flow characteristic of the fluid is determined that is correlated to the relationship between the flow rate of the fluid and nozzle pressure. Desired nozzle pressure values are periodically determined by evaluating a model of flow rate of the fluid through nozzle in response to the initial value of the flow characteristic and a desired flow rate value….

A process control system includes a diagnostic monitoring and display functionality for viewing, in a coherent manner, diagnostic information relating to a process that operates over multiple devices and system components. Although the multiple devices and system components typically encompass widely different device types and operational standards, the process control system incorporates diagnostic information relating to all devices and presents this information to a system user in a uniform m…

A method for predicting total bump height reduction from volume wear rate data for a laser textured magnetic disk. In this method, a bump topography function, r(h), is first established by which the bump half-width, r, is expressed as a function of bump depth, h. Then the bump height depth after first revolution, h.sub.1, is calculated according to the following equation: ##EQU1## Based on the observation of constant wear volume per cycle, the bump height depth after each subsequent revolution, …

An electronic measuring apparatus having a plurality of measuring modes. Each one of the plurality of measuring modes is selectively set to perform a corresponding operation. The electronic measuring apparatus includes a plurality of operational buttons. Information which associates one of the plurality of operational buttons with one of the plurality of measuring modes is stored in a memory. It is then distinguished which one of the plurality of operational buttons has been operated. Informatio…

So as to provide a network service that allows a specific service to be provided and received safely for both the user and service provider, a service provider providing a user identification file that is installed in a client computer used by a user whose user eligibility is confirmed in advance. Upon request for access from the client computer, the service provider checks for the presence of a user identification file residing in the client computer in the browser screen and provides a specifi…

A self-learning diagnostic system provides diagnostics capabilities which may be applied to a population of networked machines or components and assemblies in a product. The self-learning diagnostic system uses both the components’ own historical data and the data for an entire population of networked machines of a given product in the field as the training set to adjust critical threshold parameters for detection and diagnosis. The system includes a nominal diagnostic threshold setting module w…
