摘要： A system for process control comprises a server digital data processor and a client digital data processor that are coupled by a network, such as the Internet or an Intranet. The server digital data processor, which is additionally coupled to a control/sensing device and any associated interface equipment (collectively, referred to as “process control apparatus”), includes a command processor that transfers information between the network and the process control apparatus. The client digital data processor includes an information client (e.g., a so-called Internet web browser) capable of requesting and receiving an applet from the server digital data processor. The information client, further, defines a hardware-independent and operating system-independent virtual machine environment within the client digital data processor. The client digital data processor executes, within that virtual machine environment, an applet for configuring the client digital data processor as a “process controller” that establishes communications over the network with the command processor and that monitors and/or controls the process control apparatus via those communications.

摘要： Motion is induced in a conduit that contains a fluid. The motion is induced such that the conduit oscillates in a first mode of vibration and a second mode of vibration. The first mode of vibration has a corresponding first frequency of vibration and the second mode of vibration has a corresponding second frequency of vibration. At least one of the first frequency of vibration or the second frequency of vibration is determined. A phase difference between the motion of the conduit at a first point of the conduit and the motion of the conduit at a second point of the conduit is determined. A quantity based on the phase difference and the determined frequency is determined. The quantity includes a ratio between the first frequency during a zero-flow condition and the second frequency during the zero-flow condition. A property of the fluid is determined based on the quantity.

摘要： Disclosed is a technique for managing memory items in a cache. An “age-lock” parameter is set to protect the newer memory items. When an incoming memory item (such as a history block header) is to be added to the cache, the amount of free space in the cache is checked. If there is insufficient free space for the incoming memory item, then space is freed up by removing memory items from the cache. No memory items protected by the age-lock parameter are removed. Of the older items, the selection for removal follows any of a number of well know cache management techniques, such as the “least recently used” algorithm. A “maximum size” parameter can be set for the cache. If the cache exceeds this maximum size, then free space is released and memory items are removed to decrease the cache size.
摘要翻译：公开了一种用于管理高速缓存中的存储器项的技术。设置“年龄锁定”参数来保护较新的内存条目。当要将进入的内存项（如历史块头）添加到高速缓存中时，将检查高速缓存中的可用空间量。如果进入的内存条目的可用空间不足，则通过从缓存中删除内存项来释放空间。没有被age-lock参数保护的内存项被删除。在较旧的项目中，删除的选择遵循许多熟知的高速缓存管理技术中的任何一种，诸如“最近最少使用的”算法。可以为缓存设置“最大大小”参数。如果缓存超过此最大大小，则释放可用空间，并删除内存项以减小缓存大小。

摘要： A modular system and method is provided for enabling remote configuring and ordering of flowmeters in a client-server environment. The system includes a meter selection module configured to enable a user to select from a plurality of flowmeter types. A process data module receives process data from a client and a fluid selection module coupled to the process module is configured to receive a process fluid selection and to calculate properties thereof. A sizing module generates parameters of at least one sized flowmeter, sized in accordance with the received process data. A material selection module provides a list of materials from which the sized flowmeter may be fabricated, and a fluid rating module rates compatibility of the various materials with the process fluid selection. A results module is configured to generate data corresponding to expected performance of the sized flowmeter.

摘要： In one general aspect, methods and devices for use with multiple communications protocols automatically determine which communications protocol to use when connected to a system bus. Signals transmitted on the system bus are monitored to determine what communications protocol the system bus is using. After determining which communications protocol the system is using, a compatible communications protocol is selected from one of several communications protocols stored in a device's memory. As a result, a user may connect a device to the system bus without having to determine which communications protocol is used by the system bus. Furthermore, suppliers may stock a single type of device that is compatible with multiple communications protocols reducing overhead associated with stocking devices. In addition, a device may be switched between systems without regard to the communications protocol of the device or system.

摘要： In one oil production operation, a fluid conduit transports a fluid from a well head to a floating production platform. To prevent an occurrence of formations that obstruct the flow of fluid in the fluid conduit, a forecast is made as to whether a flow assurance curve will intersect an operating curve of the fluid conduit. In the event that the operating curve and the flow assurance curve will intersect, the appropriate personnel may be alerted so that they may attempt to prevent the hydrate forming conditions from occurring in the pipe. Which personnel are alerted may be based on a level of criticality. The level of criticality may be based on an estimated time period remaining until the flow assurance curve and the operating curve will intersect.

摘要： A method is disclosed, in a supervisory process control system environment, for installing supervisory process control software from a central software deployment server. The software distribution method includes the step of first specifying a software component for a supervisory process control application to be deployed to a remote location and a destination for the software component based upon a distributed application configuration. A software component is conditionally transmitted to the remote supervisory control computer, after the determining step, if the software component for the supervisory process control application is not present at the remote location.

摘要： A method and system are disclosed for managing Profibus device information in a distributed control system. After receiving input parameter data originating from a Profibus device message, the I/O module assembly performs steps for processing, maintaining and providing the input parameter data to a requesting control processor. The processing step includes extracting input parameter values from a received Profibus device message. The extracted input parameters are then deposited in a repository on the I/O module assembly, such that for a primary input parameter, the I/O module assembly stores at least: (1) a measured value, and (2) a status value. Furthermore, the I/O module assembly maintains a reference linking the first status parameter to the first input parameter. The I/O module assembly provides a data status value with the measured value for the first input parameter in accordance with an I/O read operation. The data status value is based on the status value for the first status parameter.
