    • A Multiple-Agent Hybrid Control Architecture (MAHCA) uses agents to analyze design, and implement intelligent control of distributed processes. A single agent can be configured to control a local process and a network of agents can be configured to control more complex distributed processes. Multiple agents interact through messages and can be either permanent or temporary. The network of agents interact to create an emergent global behavior. The network of agents support construction of closed-loop, autonomous systems which react to comply with two degrees of freedom: (1) a logic degree of freedom (useful for implementing switching between modes of control) and (2) an evolution degree of freedom (useful for implementing particular modes of control). Global behavior is emergent from individual agent behaviors and is achieved without central control through the imposition of global constraints on the network of individual agent behaviors (the logic agent network). MAHCA is especially useful for reactive synchronization of real-time distributed processes subject to decision-making under uncertainty where both logical and evolution constraints on system operation must be continuously maintained and where human operators must be kept appraised of current system operation and whose decisions must be promptly and safely executed. MAHCA also provides support for reuse of existing trusted components and incremental provision of expanded functionality in old or new components through formal construction of provably correct real-time software from declarations of desired logic and evolution behavior of system components. Finally, MAHCA agents can be used in conventional digital procedures to speed up an ensemble of procedures.
    • 多代理混合控制架构(MAHCA)使用代理分析设计,实现分布式进程的智能控制。 可以将单个代理配置为控制本地进程,并且可以将代理网络配置为控制更复杂的分布式进程。 多个代理通过消息交互,可以是永久的或临时的。 代理网络互动,创造出一种紧急的全球行为。 代理网络支持闭环自治系统的建设,这些系统对两个自由度有反应:(1)逻辑自由度(用于实现控制模式之间切换)和(2)进化自由度 (用于实现特定的控制模式)。 全局行为是从个体代理行为出现的,并且通过对个人代理行为网络(逻辑代理网络)施加全局约束而实现无中央控制。 MAHCA对于不确定性下的决策制定的实时分布式过程的反应同步特别有用,其中系统运行的逻辑和演化限制必须持续保持,并且必须对人员操作人员进行现行系统运行评估,其决策必须 及时安全执行。 MAHCA还通过从声明所需的逻辑和系统组件的演进行为的形式构建可证明的正确的实时软件,为现有可信组件的重用以及旧组件或新组件中扩展功能的增量提供支持。 最后,MAHCA代理可以用于传统的数字程序来加快程序的集合。

    • A method for evaluating inflow or outflow in a subterranean wellbore includes acquiring first and second axially spaced pressure measurements in the wellbore. The pressure measurements may then be processed to obtain an interval density of drilling fluid between the measurement locations. A tool string including a large number of axially spaced pressure sensors (e.g., four or more or even six or more) electronically coupled with a surface processor via wired drill pipe may be used to obtain a plurality of interval densities corresponding to various wellbore intervals. The interval density may be measured during static conditions or while drilling and may be further processed to compute a density of an inflow constituent in the annulus. Changes in the computed interval density with time may be used as an indicator of either an inflow event or an outflow event.

    • A UHF transmission frequency oscillator generates a UHF radio signal that is frequency modulated by a program signal. The voltage applied to a control voltage input of the UHF transmission frequency oscillator controls the transmission frequency. A sample of the UHF transmission frequency signal is heterodyned with the output of a crystal controlled reference frequency oscillator to generate a frequency difference signal. A voltage controlled VHF radio signal generator produces a VHF signal frequency modulated by the program signal. A phase detector receives the frequency difference signal and the VHF signal frequency modulated by the program signal and therefrom applies a voltage to the control voltage input of the UHF transmission frequency oscillator for the transmission of a UHF radio frequency signal frequency modulated by the program signal. The VHF voltage controlled generator has VHF programmable frequency dividers, which are pre-settable, to establish the VHF radio transmission frequency. The output of the VHF voltage controlled generator is phase locked through the phase detector with the crystal controlled reference oscillator for the stabilizing of the output transmission frequency of the UHF transmission frequency oscillator.

    • An attention signal receiver in which emergency broadcast transmissions are detected from various locations. A scanning circuit sequentially activates means to produce a plurality of oscillating frequencies which mix or beat with the incoming r.f. signals. An attention signal is a two tone signal that includes both a 960 H.sub.z frequency signal and a 853 H.sub.z frequency signal. The audio stage of the receiver is connected to a two tone decoder that passes only a 960 H.sub.z signal and a 853 H.sub.z signal. A squelch circuit is also connected to the audio stage of the receiver. Connected to the output of the tone decoder is a one second time delay circuit and a ten second time delay circuit. If an attention signal is detected for a period of time in excess of 1 second, the one second time delay circuit stops the scanning of the scanning circuit to lock in the receiver to the first carrier detected with an attention signal. The ten second time delay circuit normally disables the squelching circuit. If the detected attention signal continues for a period of time in excess of 10 seconds, the ten second time delay circuit enables the squelch circuit to operate an alarm.
    • 一种注意信号接收器,其中从各个位置检测到紧急广播传输。 扫描电路依次激活装置以产生与输入的r.f混合或拍击的多个振荡频率。 信号。 注意信号是包括960Hz频率信号和853Hz频率信号的双音信号。 接收机的音频级与仅通过960Hz信号和853Hz信号的双音解码器连接。 静噪电路也连接到接收机的音频级。 连接到音调解码器的输出是一秒钟延时电路和十秒延时电路。 如果在超过1秒的时间内检测到注意信号,则一秒钟延迟电路停止扫描电路的扫描,以将接收器锁定到用注意信号检测到的第一载波。 十秒钟延时电路通常禁用静电电路。 如果检测到的注意信号持续超过10秒的时间段,则十秒钟延迟电路使得静噪电路能够进行报警。
