    • A dialog processing method and apparatus for uninhabited air vehicles is described. The apparatus contains a recognition unit for recognizing incoming data, an interpretation unit for interpreting the data according to a grammar and a response unit for generating an appropriate response to the incoming data. The method may utilize natural language processes and may reduce to a finite state machine. The incoming data is combined with uninhabited air vehicle state information to increase the accuracy of this interpretation. Additionally, the dialog states may be limited to customary air traffic control dialogs.
    • 描述了一种无人驾驶飞行器的对话处理方法和装置。 该装置包括用于识别输入数据的识别单元,用于根据语法解释数据的解释单元和用于生成对输入数据的适当响应的响应单元。 该方法可以利用自然语言过程并且可以减少到有限状态机。 输入数据与无人机动车状态信息相结合,以提高此解释的准确性。 此外,对话状态可能限于常规空中交通管制对话。

    • A real-time distributed model-based predictive control method having a time maintenance mechanism that solves all state synchronization problems. Method steps include generating a message that predicts a system value corresponding to a future time, and executing a control process using the system value contained within said message, resulting in a process state. The process state is then stored in a state queue. The local process time is rolled back to the latest valid local process time prior to said message if the message precedes the current process state time. Rolling back comprises retrieving the system state values at that latest valid local process time from said state queue and re-executing the control process, using the system value contained within the message, and storing the new state in the state queue. The method also includes rolling back if, upon receiving a message containing an observed system value, said observed system value differs from its predicted value by more than a predetermined tolerance. The method is carried out on a distributed processor control system.
    • 一种实时分布式模型预测控制方法,具有解决所有状态同步问题的时间维护机制。 方法步骤包括生成预测对应于未来时间的系统值的消息,以及使用包含在所述消息内的系统值来执行控制处理,从而产生处理状态。 然后将进程状态存储在状态队列中。 如果消息在当前进程状态时间之前,则本地进程时间将在所述消息之前回滚到最新的有效本地进程时间。 回滚包括从所述状态队列检索在该最新的有效本地进程时间的系统状态值,并使用包含在消息内的系统值重新执行控制进程,并将新状态存储在状态队列中。 该方法还包括回滚,如果在接收到包含观察到的系统值的消息时,所述观察到的系统值与其预测值不同超过预定公差。 该方法在分布式处理器控制系统上进行。

    • A method of measuring healing strength of bone includes a bone fixation plate (14) implanted at the healing area between bone segments (12). The bone fixation plate (14) includes high aspect ratio material with electric current conduction properties responsive to strain. This method causes an induced, or directly applied, electric current to pass through the high aspect ratio material. Analysis of the change in this current by a series of increasing loads placed on the healing body part indicates what level of load produces strain on the bone fixation plate (14). As healing strength increases, evidence of strain on the bone fixation plate (14) occurs at a greater load. Physicians determine thereby the strength of bone healing and safe levels of activity for patients while bone healing progresses.
    • 测量骨的愈合强度的方法包括植入在骨段(12)之间的愈合区域处的骨固定板(14)。 骨固定板(14)包括响应于应变的具有电流传导性质的高纵横比材料。 该方法使感应或直接施加的电流通过高纵横比材料。 通过放置在愈合体部分上的一系列增加的负载来分析该电流的变化表示什么水平的负载在骨固定板(14)上产生应变。 随着愈合强度的增加,骨固定板(14)上的应变证据发生在更大的负荷。 因此,骨骼愈合过程中,医师确定了骨骼愈合的强度和患者的安全活动水平。

    • The present technique provides for the analysis of a data series to identify sequences of interest within the series. The analysis may be used to iteratively update a grammar used to analyze the data series or updated versions of the data series. Furthermore, the technique provides for the calculation of a minimum description length heuristic, such as a symbol compression ratio, for each sub-sequence of the analyzed data sequence. The technique may then compare a selected heuristic value against one or more reference conditions to determine if additional iteration is to be performed. The grammar and the data sequence may be updated between iterations to include a symbol representing a string corresponding to the selected heuristic value based upon a non-termination result of the comparison. Alternatively, the string corresponding to the selected heuristic value may be identified as a sequence of interest based upon a termination result of the comparison.
    • 本技术提供数据序列的分析以识别该系列内的感兴趣序列。 该分析可用于迭代地更新用于分析数据系列或数据系列的更新版本的语法。 此外,该技术提供了对分析数据序列的每个子序列的最小描述长度启发式(例如符号压缩比)的计算。 然后,技术可以将所选择的启发式值与一个或多个参考条件进行比较,以确定是否要执行附加迭代。 可以在迭代之间更新语法和数据序列,以基于比较的非终止结果来包括表示对应于所选择的启发式值的字符串的符号。 或者,可以基于比较的终止结果将对应于所选择的启发式值的字符串识别为感兴趣的序列。
